The International Information System Security Certification Consortium Certifications, or else known as the ISC², is considered to be a non-profit organization that would be dedicated in certifications and training for cybersecurity professionals. It would be often expressed as the world's leading IT security organization. We are going to discuss the ISC Certification Preparation Steps to help you out in accomplishing the same.
Below mentioned are the steps to obtain the ISC Certifications
Step 1: (ISC)2 Certification Program Overview
The first thing is to know and decide which (ISC)2 Certification Program would be best for you. They would be offering six-core security credentials:
Systems Security Certified Practitioner (SSCP)
Certified Information Systems Security Professional (CISSP)
Certified Authorization Professional (CAP)
Certified Secure Software Lifecycle Professional (CSSLP)
HealthCare Information Security and Privacy Practitioner (HCISPP)
Certified Cloud Security Professional (CCSP)
Also, if you gain the training program, which is being offered at the SPOTO Club’s ISC Certification module, you’ll earn better results.
Step 2: (ISC)2 Resources
Online Training: When studying for ISC Certification I would go through the SPOTO Club’s ISC Online Training. I found this a great way for maintaining to ISC Certification study consistency. The content would be pre-2015 ISC Certification exam, however, it was considered useful with reinforcing concepts like the Security Models still used in today’s exam.
Study Dumps: Most of the candidates who are pursuing the ISC Certification, use the study dumps, which they get it for free and as a result fail miserably. On top of it, they blame the dumps and not their selection. Thus it is recommended to have reliable study dumps like that offered at the SPOTO Club’s ISC Dumps Section.
Step 3: Practice Exams (Plenty!)
The exam would be testing you on Common Body of Knowledge (CBK) available at various ISC Certification Exams. Practice exams would be your way of measuring your ability to pass it! Practice exams would be just as important as the study materials. You would be also anticipating using a variety of different exams. I would have seen some candidates stating that they have practiced 5000 questions before sitting the ISC Certification exam. I would estimate that I might have completed 2000 practice questions as part of my preparation, which I have gained at the SPOTO Club’s ISC Exam Section.
SPOTO Club ISC Certification module would be offering ISC Certification scenario-based questions, which I recommend to readers who are unfamiliar with scenario style questions. Practice exams would be giving you a good idea of what to expect in the exam.
Step 4: Know the Exam
Be prepared to see scenario or judgment based questions containing like the BEST/MOST/LEAST. You would be presented a scenario as well as you need to pick the best option out of the multiple choices which would be provided to you, in some cases all options presented might be correct. This could take you off guard as more than one of the options would be correct, at least logically! You would be required to think of this from a managerial perspective as well as select the best option.
Step 5: Finally Clear The Exam
Given the time constraints, you would be required to have a strategy for your exam. As you would be needed to gain the best out of the time you would have available. How you would be choosing to tackle answering questions is at the discretion of the individual depending on the style that would be suiting them best.
So, like this, you could obtain the ISC Certifications, and SPOTO Club’s ISC Certification Modules would help you a lot in clearing your ISC Certification in a single attempt. So, check out their courses for better results.

When it comes to getting your Cisco CCNA Routing & Switching certification, the biggest question might be whether or not it is worth it. If you have ever bothered asking anyone this, you have likely heard something along the lines of It depends. Sure, it depends on certain things, but that is not a very valuable or insightful response. So, take a little time to get more in-depth with this common question and then dive right into whether or not you should consider the CCNP. Before we get into it, if you do wish to opt for this certification, the best way to achieve it would be by enrolling yourself to the courses offered at the SPOTO Club.
Experience Matters, But still CCNP is needed
Even if you hold a tremendous amount of experience, you still need your CCNP, because of perception matters. If you have been in networking for a while, but do not have your CCNP, you will look like you aren’t interested in learning. There’s also the risk that a hiring manager may not take you seriously if you get to a hiring manager. Having CCNA experience is good -- but having both the CCNA and the CCNP is better, even if you lack in on-the-job experience. We, the IT folks know that a certification does not replace experience, but many hiring managers see it differently. Hiring managers rely on certifications as proof of knowledge and in their eyes certification equals experience. Combine this with the fact that the CCNP exams need you to perform configuration and troubleshooting tasks; the CCNP does prove experience just not on the job experience.
CCNP in Spotlight
The initial investment which you would be making into getting your CCNP may pay off quickly, but it would be almost certainly pay off over time. Many times the candidates let their CCNP expire without re-certifying. Later they found a high-paying systems engineer position which demands the CCNP as a requirement. That’s how powerful the CCNP could be.
High Income Opportunities
How much will you make with the CCNP R&S certification? The short answer is this As much as you want. Ultimately, it comes down to experience, certifications, the market, and the company. Do not believe salary surveys. There are just too many variables that impact those figures. The bottom line is that you will make significantly more as a CCNP than you will as a CCNA, all other things being equal.
Vendor-neutral certifications and other vendors
It is common after getting your CCNA to consider pursuing other entry-level network certifications like the CompTIA Network+ and Juniper. Vendor-neutral certifications and other vendor certifications may considered to be valuable, but they are not replacements for Cisco certifications. If you have proven Cisco's expertise, it shows you are fully capable of learning other vendors. "We don't make use of Juniper,” is a common exhortation among businesses whereas “We don’t make use of Cisco,” is the kind of statement that makes a room go silent.
Conclusion
If you are passionate about networking and wish to make a career out of it, the CCNP Routing & Switching certification is a no-brainer, for you. Not only will it give you a sense of accomplishment, but it would also make you much more marketable by helping you gain more, and providing additional job security. Thus, we can say that CCNP Routing and Switching worth each and every penny you spend on it. Also, to achieve this certification, you are going to need a good and reliable training center. I would recommend you to check out the courses offered at the SPOTO Club, to ensure your success.

I. Understanding CCNA and CCNP Certifications
Cisco offers a range of certifications for IT professionals seeking career advancement. You can opt for the Cisco Certified Network Associate (CCNA) or the Cisco Certified Network Professional (CCNP) certifications, or even pursue both. However, it's essential to grasp the essence of each certification before deciding on the right path for your career.
CCNA (Cisco Certified Network Associate)
The CCNA certification is the initial step in the Cisco certification hierarchy. It provides a comprehensive overview of fundamental networking concepts and terminology. CCNA aims to equip candidates with knowledge in network fundamentals, network access, IP connectivity, IP services, security fundamentals, and automation and programmability.
CCNP (Cisco Certified Network Professional)
Considered a level above CCNA, CCNP targets professionals with a basic understanding of networking. This certification offers a more detailed and in-depth study of networking concepts and scenarios, involving intricate configurations and troubleshooting procedures.
II. CCNP without CCNA: Possibilities and Implications
For IT professionals, deciding whether to pursue the CCNA or directly attempt the professional-level CCNP certification requires careful consideration. Here are some crucial points to ponder:
Passing CCNP without CCNA
It is possible to attempt and pass the CCNP certification without first obtaining the CCNA certification. However, the CCNP is more complex and challenging. Without the foundational knowledge from CCNA, passing the CCNP can be exceedingly difficult.
Is CCNP Harder than CCNA?
The CCNP is generally more challenging than the CCNA due to its depth and complexity. However, the level of difficulty is subjective and depends on an individual's prior knowledge, experience, and preparation strategy.
The Importance of On-the-Job Training
To grasp the complexities of the CCNP, hands-on training or practical job experience is advisable. Practical experience enhances understanding and increases the chances of passing the certification exam.
III. Comparing the CCNA vs CCNP Certifications
When exploring Cisco certifications, two prominent options are CCNA (Cisco Certified Network Associate) and CCNP (Cisco Certified Network Professional). Let's examine the prerequisites and areas of focus for both certifications.
The Prerequisites for Both CCNA and CCNP
CCNA has no official prerequisites, although a good understanding of networking fundamentals is recommended. In contrast, CCNP requires at least the CCNA certification or any Cisco Certified Internetwork Expert (CCIE) certification, along with a deep understanding of networking principles.
Distinguishing the Areas of Focus
CCNA focuses on networking fundamentals, while CCNP delves deeper into these concepts. CCNP allows for specialization in various areas, making it valuable for IT professionals.
Importance of CCNP's Advanced Coverage
CCNP's advanced coverage of topics like security, VoIP, and wireless options sets it apart. In today's data-driven world, network security is crucial, making CCNP a valuable certification for IT professionals.
IV. Salary Expectations: CCNA Vs CCNP
Salary considerations are vital when choosing a certification. Let's examine the salary expectations associated with CCNA and CCNP certifications.
CCNA Salary
In the United States, CCNA-certified professionals can expect an average annual salary of around $109,474, making it a worthwhile investment.
CCNP Earnings
CCNP-certified professionals generally earn more than CCNA-certified individuals, providing a significant career boost.
V. The Transition from CCNA to CCNP
Traditionally, professionals followed the CCNA to CCNP path. However, recent changes require CCNP candidates to have at least the in-progress status of the corresponding CCNA exam, emphasizing a comprehensive understanding of networking basics before advanced topics.
VI. Weighing the Value of CCNA and CCNP
Both CCNA and CCNP certifications hold significant value in the IT industry, offering various benefits. CCNA serves as a foundational step, while CCNP signifies advanced networking knowledge and skills, leading to broader career opportunities.
Obtaining these certifications enhances career prospects, increases salaries, and opens doors to more senior roles. CCNA and CCNP certifications shape IT professionals' careers and contribute to career satisfaction and job security.

It would be allowing the candidates to maximize their investment in their education, and increase their professional value by giving them the skills so as to help their IT organization to meet increased business demands which would result from these technology transitions.
Because the CCIE Collaboration Written exam would be assuming the familiarity with a variety of unified communications solutions, you would certainly benefit by first successfully completing both the voice/collaboration associate and professional level certifications. Then, you would be able to fill in the gaps through self-study.
Perhaps you might have the luxury of working with some of these technologies in your current employment. If so, you might want to check into the feasibility of constructing a collaboration lab topology, which would help you to prepare for not only the CCIE Collaboration Written exam but also eventually the CCIE Collaboration Lab exam.
Cisco offers expert-level CCIE Collaboration training which would be acquired through its Cisco 360 program. The candidates pursuing this certification would be made it easy if they acquire a good training session, which they could gain by joining SPOTO.
The Cisco Expert-Level Training for CCIE
Additionally so as to your hands-on practice, you would also need to do quite a bit of reading so as to deepen up your understanding of key topics that would be appearing on the CCIE Collaboration blueprint. A collection of recommended books are provided in the section of recommended study resources.
Many CCIE Collaboration Lab candidates are going to benefit from collaborating with other candidates during their study. You are required to be familiarizing yourself with the CCIE Collaboration Lab study group that would be available at the Cisco Learning Network (CLN)
If you do not possess a good fortune of working with these technologies, you might consider renting it out from one of the many CCIE training companies, who provides the same. Or you might have to invest in a series of Cisco Press books.
Finally, if your budget allows, you are required to consider attending a CCIE Collaboration Written boot camp. Personally, the main benefit I would have seen from attending a boot camp is that it would seem so as to compress time. While you are preparing for my first attempt at the CCIE Voice Lab, the candidates are required to attend a week-long boot camp. Upon leaving the boot camp, you would remark that you would have learned more in that one week than you would have in a month and a half of independent study. So, although the candidates feel that they could reach that level on their own, might have taken much longer.
The most important element of your preparation is hands-on practice. You would have to either rent rack time or construct your own home lab. You would be required to expect to put in a minimum of 500 to 700 hours in order to practice rack time.
So, you need to have good and proper training that would be acquired by joining a good training provider like the SPOTO. They have the latest and reliable study dumps, which you could rely on totally, as they also provide you the passing guarantee.

It would be basically an entry level certification which would require no additional qualification. You would have to appear for the EX 200 which is considered to be a half day hands-on lab exam. The certification or the exam would be focused on your ability of system administration. This would be including the installation as well as the configuration of Red Hat Enterprise Linux operating systems.
II. Red Hat Certified Engineer (RHCE)
RHCE is considered to be a more advanced level certification as it would be covering a wider syllabus. It would be giving you the ability to move from mid-level to advance level. The pre-requirement for RHCE would be the RHCSA. Once you would have fulfilled the condition you need to take up EX 300, which would be again a hands-on lab-oriented exam of two hours. This exam would be focusing on topics like installation along with network security. Being an RHCE, you would be considered capable of all RHCSA tasks which would also include the following:
Configuration, network translation, and packet filtering
Interface initiator
Maintenance
Setting the kernel
Shell scripting
III. Difference between RHCSA vs RHCE:
Although both of the certifications, RHCE as well as RHCSA, would give you enough knowledge as well as recognition in the industry, there would be considered as a valid amount of difference between the two certifications. The RHCE credential would be helping you to acquire more key and important roles in IT companies as a senior system engineer or system engineer whereas RHCSA would be considered as a prerequisite to gain the key roles in organizations as a system administrator or senior system administrator. Getting more advanced Certification, RHCA (Red Hat Certified Architect) certification could land you in big roles in the architecture department of a reputed IT organization.
RHCE Certification would be considered as more advanced level certification which would be covering a wide range of syllabus as well as it would give you more chances of employment and recognition in the corporate world. So as to become eligible for an RHCE Certification, one is required to pass the exam and acquire an RHCSA Certification first.
Moreover, an RHCE Certification would be allowing the candidates to be eligible for the more advanced level of Red Hat certifications which could really prove crucial for your carrier giving it a range as well as a wide spectrum that it deserves. You could either opt for an RHCA (Red Hat Certified Architect), RHCSS (Red Hat Certified Security Specialist) or even an RHCDS (Red Hat Certified Datacenter Specialist). These certifications could really change the course of your carrier and give you more than enough edge among other competitors for securing that high profile job in a big IT company that you would have always wanted for yourself. They can also improve your skills and knowledge.
So, whether you chose any of them, you are required to go through some good training courses, which you could gain at the SPOTO. They provide the best preparation courses, in the various IT Certifications. Also, you can practice exam questions with SPOTO 100% real exam dumps.

We would be here covering the basic OSPF concepts as well as their operation. We would explain about the working of OSPF, how to build OSPF tables on an OSPF-enabled router as well as their purpose, OSPF areas, and their importance. Next, we would be covering the OSPF Link State Packet types which would be utilized to exchange data between OSPF routers: LSA (Link State Advertisement), LSDB (Link State Database), LSR (Link State Request), LSAcK (Link State Acknowledgment) and LSU (Link State Update). Later on, we might be taking a look at the OSPF roles: ABR (Area Border Router), ASBR (Autonomous System Boundary Router), DR (Designated Router), Backup DR and much more. So if you wish to have knowledge about all these topics and if you wish to have proper hands-on practice on the same, join our courses at SPOTO to have more knowledge regarding the OSPF. So, let’s begin.
What Is OSPF And How Does It Work?
OSPF is considered as a Link State protocol that’s which would be believed to, may be the most famous protocol among the IGP (Interior Gateway Protocol) family, developed in the midst of 1980s by the OSPF working group of the IETF.
When configured, OSPF would be able to listen to neighbors and gather all link state data available to build a topology map of all available paths in its network and later on save the information in its topology database, which would be also known as its LSDB (Link-State Database).
Utilizing the information from its topology database:
From information which would be gathered, it would be calculating the best shortest path to each reachable subnet or network utilizing an algorithm called SFP (Shortest Path First) which was developed by the computer scientist Edsger W. Dijkstra in the year 1956. OSPF would be then constructing three tables to store the following information:
Neighbor Table: It would contain all discovered OSPF neighbors with whom routing information will be interchanged
Topology Table: It would contain the entire road map of the network with all available OSPF routers and calculated best and alternative paths.
Routing Table: It would contain the current working best paths that will be used to forward data traffic between neighbors.
Understanding OSPF Areas:
OSPF would be offering a very distinguishable feature namely the Routing Areas. It means it would be dividing routers inside a single autonomous system that is running OSPF, into areas where each area would be consisting of a group of connected routers.
The idea of dividing the OSPF network into areas is to simplify the administration as well as optimize the available resources. Resource optimization would be especially important for large enterprise networks with a plethora of network as well as links. Having many routers exchange the link state database could flood the network as well as reduce its efficiency. Thus, this was the need which led to the creation of concept Areas.
Areas which are considered as a logical collection of routers which could be carried to the same Area ID or number inside of an OSPF network, the OSPF network itself could contain multiple areas, the first as well as the main Area would be considered as the backbone area “Area 0”, all other areas should be then connected to Area 0.
So, now you would be aware of how much things that you are needed to have the knowledge of while preparing for the Cisco Lab Exams. But Don’t Worry! SPOTO is there to help you. Join the CCIE Lab Exam Courses, which are being offered at the SPOTO and gain access to their Premium Lab materials and lots more.

Solutions to the problem of data packet forwarding
In the previous two articles, we solved two problems: the routing conflicts in the local PE and the conflicts in the propagation process of the routing network, the problem of the schematic diagram RD format has been solved.
However, when data is forwarded, if there are 10.0.0.0/24 routes in the two local VRFs of the receiving PE, when it receives a packet with a destination address of 10.0.0.1, how does it know to send this packet? Which VRF is the CE connected to? Certainly need to add some information in the forwarded message. Of course, this information can be taken care of by RD. It is only necessary to transform the processing flow of MPLS VPN so that the data can also be carried when carrying RD.
But the RD has a total of 64 bits, which is too large, which will reduce the forwarding efficiency. To ensure efficiency, only a short, fixed-length mark is needed. Since the public network tunnel is already provided by MPLS, and MPLS supports nesting of multiple layers of labels, this label can be defined as the format of MPLS labels. Who will assign this label? The routing is private VPN, and LDP knows nothing about it. This task of assigning VPN private network routing labels can only be accomplished by extended BGP. Similar to the LDP protocol, label distribution is done before data forwarding occurs. The difference is that MP-IBGP assigns labels simultaneously with route exchange.

VPN-IPv4 Address family

It is the PE router itself, usually the LOOPBACK address
NTRL

Prefix
Rd:64bit+ip prefix
We know that BGP exchange routing is accomplished through NLRI (Network Layer Reachability Information). Through the transformation of BGP protocol, the modified MP-IBGP will append various information such as RD and label when NLRI information exchange. In this way, the routing exchange and data forwarding problems of the entire MPLS VPN are solved. Let's introduce the process of routing exchange and data forwarding of MPLS L3VPN.
MPLS L3VPN routing exchange and data forwarding process
As mentioned earlier, when MPLS L3VPN routes are exchanged, the PE router runs a single routing protocol (MP-IBGP) to exchange all VPN routes. To support the overlapping of VPN client spaces, add RD to the VPN address space to make it unique. And use the RT attribute to indicate the VRF to which the route belongs. We can summarize it as follows.
The routing exchange process of MPLS VPN is mainly divided into four parts:
■ Routing exchange between CE and PE;
■ The process of VRF route injection into MP-IBGP;
■ Public network label distribution process;
■ The process of MP-IBGP route injection into VRF.
Let's analyze the whole process of MPLS VPN routing exchange between PEs through examples.
Route exchange between CE and PE
Schematic diagram of route exchange between CE and PE
The exchange process is as follows:
Configure VRF for different VPN sites on the PE. PE maintains multiple independent routing tables, including public and private network (VRF) routing tables, including:
■ Public network routing table: contains all the routes between PE and P routers, and is backed by the backbone network IGP
Produce
■ Private network routing table: The routing and forwarding table that contains the reachable information of this VPN user.
Routing information is exchanged between PE and CE through standard EBGP, OSPF, RIP or static routes. In this process, except that the PE device needs to store the routes from the CE device in different VRFs (this is only related to the route receiving interface and has nothing to do with other MPLS VPN features), other operations are no different from ordinary route switching.
Static routing and RIP are standard protocols. All CE terminals can use the same routing protocol, but each VRF on the PE terminal needs to run a different instance, and there is no interference with each other. Simple introduction of each other. The situation of EBGP is similar to RIP. It is also ordinary EBGP instead of MP-EBPG, which only exchanges the VPN routes filtered by PE. However, choosing OSPF as the routing protocol between PE and CE is relatively complicated. Many modifications to OSPF are required to carry the LSAs of this site in the extended community attribute of BGP and exchange LSAs with OSPF in the remote VPN. OSPF in each site can have area 0, and the backbone network can be regarded as super area 0. At this time, OSPF changes from a two-level topology (backbone area + non-backbone area) to a three-level topology (super backbone area + backbone area + non-backbone area). For more detailed introduction of OSPF in MPLS VPN network, please refer to other related documents of MPLS VPN, which will not be described in detail here. This completes the route exchange process from CE to PE.
The process of VRF route injection into MP-IBGP
VRF route injected into MP-IBGP and route exchange diagram between PE
As shown in the figure, the process of injecting VRF routes into MP-IBGP and exchanging them between PE devices through MP-IBGP is as follows:
After receiving the routing information from the CE, the PE router needs to add RD to the route (RD is manually configured) to make it a VPN-IPv4 route. Then change the next hop attribute to yourself (usually your own loopback address) in the route advertisement, add a private network label to this route (generated automatically by the MP-IBGP protocol, no configuration required), and add the RT attribute (RT Need to be manually configured). After this series of work is completed, the PE sends it to all other PE neighbors. Other PE neighbors also perform the same operation to exchange routes on different CE ends.
Public network label distribution process
Schematic diagram of the public network label allocation process
The private network routing exchange between PEs needs to cross the MPLS backbone network. In this process, standard MPLS forwarding needs to be performed. Therefore, to properly route the route to the peer PE, you need to know the public network label that reaches the peer PE. As shown in the figure, the process of public network label assignment is as follows:
First, the PE and P routers learn the address of the next hop of the BGP neighbor through the backbone network IGP. By running the LDP protocol, labels are assigned, and LSP channels are established. The label stack is used for packet forwarding. The outer label is used to indicate how to reach the next hop of BGP. The inner label indicates the outbound interface of the packet or which VRF (which VPN) it belongs to. MPLS node forwarding is based on the outer label, regardless of the inner label. At this time, through the outer label space of MPLS, normal routing exchange can be performed between PE devices.
The process of MP-IBGP route injection into VRF
Schematic diagram of the process of MP-IBGP route injection into VRF
As shown in the figure, after receiving the route sent by the sending PE, the receiving PE changes the VPN-v4 route to an IPv4 route, and adds the route entry to the corresponding VRF according to the import RT attribute of the local VRF. The private network label Keep it, record it in the forwarding table, and use it for forwarding. It is then introduced by the routing protocol of this VRF and passed to the corresponding CE. When sending to CE, the next hop is the interface address of the receiving PE. This completes the process of injecting MP-IBGP routes into VRF.
After the above four steps, the routing exchange of the entire MPLS VPN network is completed. At this point, the VPN is constructed and normal business data can be forwarded.
