CCIE Routing and Switching: It would be quite a surprising fact to note that the industry demands for around 300,000 CCIE Routing and Switching certified professionals, whereas it has only 35000 active professionals as on date. This would be speaking about the huge skill shortage. As a layman, we all know that with the demand and supply imbalance, where demand is higher than the supply, we have the opportunity to en-cash it for high packages for respectable positions in the networking domain. CCIE Security: The challenging era of digitization and internetworks, there is a strong demand for expert IT infrastructure professionals who can design, administer and maintain secured networks ensuring smooth functioning throughout the enterprise environment. According to the stats, there are only 6000 security professionals while the demand is nearly around 200000 which is an amazing opportunity to have a secured career with a great future. Both of them holds an eminent place and whether you select any of them, you would require a good training course, like that offered at the SPOTO Club.

CCIE Security certification would open doors to multiple profiles in the Networking domain depending on their skill sets. Let’s take a look at the options that you would be able to have after CCIE Security: Network Security Administrator Network Security Engineer Senior Network Engineer Security Analyst Network Security Engineer Network Security Specialist CCIE Routing and Switching vs CCIE Security – Benefits and Comparison:- Demand vs Supply Gap of CCIE Routing and Switching and CCIE Security: CCIE Routing & Switching is most famous CCIE track and there are only around 35,000 CCIE Routing and Switching Certified Engineers in the entire world whereas world needs over 3,00,000 CCIE Routing and Switching Engineers right now. CCIE Security, on the other hand, is the most reputed and highest-paid IT Certification ever. If you are a CCIE Security Certified Engineer, then you would be considered amongst those 6,000 Network Security Superheroes who are cut above the rest. You will be amazed to know that there are not more than 6,000 CCIE Security certified Engineers worldwide, whereas industry needs over 2,00,000 CCIE level Security Engineers right now. Salary Packages and Growth/Scope – CCIE Routing and Switching vs CCIE Security: If you are a CCIE Routing and Switching Certified engineer, you can easily start your career at Approx.  $100,000 package and reach up to Approx.  $400,000 package within 10 years. If you are a CCIE Security Certified Engineer, then you can easily kick start your career from Approx. $120,000 package and reach up to Approx.  $450,000 package with 10 years of hard work. In the end, here is a quick reminder that both of these tracks have the same importance. Do some more research and choose wisely among the two. It is considered to be much better if you pick that course in which you would find yourself involved. This means that you are required to have interests in that specific field and you should enjoy your work. If you have interests in Routing and Switching then go for it, then don't go for CCIE Security just because of its higher salary. And if you do this then soon you will find discomforts in your job. Also, whichever you choose, if you wish to ease up your study process, do check out the Study dumps, offered at the SPOTO Club.

CCIE Routing and Switching v4.0 Quick Reference: Network Optimization would be covering the SLAs, SPAN, RSPAN, NetFlow, and RITE as well as Cisco IOS EEM. IP Service Level Agreement (SLA) One of the most important aspects that would be needed to consider in maintaining a network is providing a guarantee of an explicit level of service to customers. In order to ensure that such an agreement is met at all times, IOS would be providing a mechanism so as to actively test specific metrics, called IP SLA. When configured, the IP SLA service would be active monitors a specific aspect of the network, like the DNS response time, UDP VOIP jitter, ping latency, and so on. If the IP SLA thresholds are not met, IOS would be sending a notification, like an SNMP trap or syslog message.  NetFlow:  As packets are going to be sent through router interfaces, they could be classified into flows. This information could be sent from the router so as to monitor the server that could be providing valuable information about the traffic traversing the network. A flow could be described by a number of fields: Destination IP address Destination port Interface Protocol type Source IP address Source port Type of Service In order to determine if a packet belongs in a particular flow, the seven packet fields are going to be inspected. If anyone of the fields would be different, the packet in question which could be considered a new flow. NetFlow statistics could be collected on the following types of networks: IP, MPLS, Frame Relay, and ATM. You could learn all of these in detail, by joining the SPOTO, which is the best institute for Cisco Certifications.  SPAN, RSPAN, and RITE (Router IP Traffic Export) Viewing the packets between two devices is often considered the best way to troubleshoot a networking issue. Many organizations would be deploying network monitoring servers for both network functionality as well as security purposes. In order to provide these servers a stream of data from all the segments of the network, the Switched Port Analyzer (SPAN) mechanism built into Cisco switches would be utilized. A SPAN port is considered as a physical port that is configured so as to send data which would be received on other ports or VLANs. When the data is sent out the SPAN port, it would be simply a copy of all the data that would have been sent through the configured source ports. The SPAN functionality assumes that the destination of the traffic would be directly connected to the switch. If the network is large, it might be not possible to wire a single monitoring station to multiple switches along with SPAN ports. Fortunately a special remote SPAN (RSPAN) VLAN could be created that would be transporting the SPAN port information into another switch. This would be enabling aggregation of monitoring data into a single VLAN that could be sent to the monitoring station.  Cisco IOS Embedded Event Manager (EEM) In the normal operations of the switch or router, events like the CLI command, a syslog message, or an SNMP trap, for example, could be occurring constantly. These events would be detected by the EEM Event Detectors that would be sending their information to the EEM server. The EEM server can then be programmed for the implementation of an EEM policy. Now, if you wish to learn all of it in detail, you could do it by joining the preparation courses which are being offered by the SPOTO. When it comes to various IT certifications, SPOTO would be considered the best destination for you.
