F5 Networks, Inc. is considered a global company that would specialize in application services as well as application delivery networking (ADN). F5 technologies are considered to be focused on the delivery, performance, and availability of web applications, as well as the availability of servers, cloud resources, data storage devices, and other networking components. F5 is headquartered in Seattle, Washington, with additional development, as well as sales/marketing offices worldwide. I would recommend that if you wish to make a career in the IT Industry, SPOTO Club’s prep courses would be a nice place, to begin with. Corporate history F5 Networks originally have been named F5 Labs, which have been established in 1996. The company name was inspired by the 1996 movie Twister, in which reference was made to the fastest as well as the most powerful tornado on the Fujita Scale: F5. F5's first product was a load balancer called BIG-IP, which was launched in 1997. When a server went down or became overloaded, the BIG-IP task was to direct the traffic away from that server to other servers that would be able to handle the load. In June 1999, the company had its initial public offering as well as was listed on the NASDAQ stock exchange with symbol FFIV. Competitors would have included Cisco Systems, until 2012, Citrix Systems, as well as Radware. François Locoh-Donou was replaced by John McAdam as president as well as CEO on April 3, 2017. BIG-IP F5's BIG-IP product family would comprise of hardware, modularized software, as well as virtual appliances that would be running the F5 TMOS operating system. Depending on the appliance which would be selected, one or more BIG-IP product modules could be added. These Offerings included: LTM (Local Traffic Manager): Local load balancing which was based on a full-proxy architecture. ASM (Application Security Manager): A web application based firewall. APM (Access Policy Manager): Providing access control as well as authentication for HTTP and HTTPS applications. AFM (Advanced Firewall Manager): On-premises DDoS protection, data center firewall. AAM (Application Acceleration Manager): through technologies like caching and compression. IPI (IP Intelligence): Blocking known bad IP addresses, prevention of phishing attacks as well as botnets. WebSafe: It would be helping the candidates to Protects against sophisticated fraud threats, client-less malware detection, leveraging advanced encryption as well as session behavioral analysis capabilities. BIG-IP DNS: Distributes DNS as well as application requests based user, network, and conditions of cloud performance. BIG-IP history On September 7, 2004, F5 Networks have released version 9.0 of the BIG-IP software in addition to appliances for running the software. Version 9.0 also marked the introduction of the company's TMOS architecture, with noteworthy enhancements which would be including: Moved from BSD to Linux for handling system management functions (disks, logging, bootup, console access, etc.) Creation of a TMM (Traffic Management Microkernel) for directly talk to the networking hardware as well as handle all network activities. Creation of the standard full-proxy mode, which would fully terminate the network connections at the BIG-IP as well as establishing new connections between the BIG-IP as well as the member servers in a pool. This would be allowing the candidates for optimum TCP stacks on both sides as well as the complete ability to modify traffic in either direction. BIG-IQ F5 describes the BIG-IQ as a framework for the management of the BIG-IP devices as well as application services, irrespective of their form factors (software, hardware or cloud) or deployment model (private/public, on-premises cloud or hybrid). So, if you wish to gain good and reliable study materials for the IT certifications, you could gain it offered by the SPOTO Club.

The 101-Application Delivery Fundamentals exam is the first exam required to achieve the F5 Certified BIG-IP Administrator status. All candidates are required to take this exam to move forward in the program. On completing the 101-Application Delivery Fundamentals exam successfully, it would be acknowledging the skills as well as understanding necessary for the day-to-day management of Application Delivery Networks (ADNs). Before we discuss the Guide in detail, if you wish to make a career in the IT certification, you should gain the study dumps offered at the SPOTO Club Section 1 – OSI Application Delivery Fundamentals The first section of the exam would be concentrating on some basic networking concepts, working up the OSI model from the bottom. This section would be worth 33% of the total test score. Objective 1.01 – Explaining, comparing and contrasting the OSI layer OSI Model Wiki Another OSI Model Overview   Objective 1.02 – Explaining technologies and protocols specific to the data-link layer ARP ARP on F5 MAC Address Broadcast Domain VLANs Link Aggregation Wiki Big IP Link Aggregation Objective 1.03 – Explaining apply and protocols technologies specific to the network layer Routing on F5 TCP/IP Overview IP Addressing & Subnetting Routing Protocols IP Packet Fragmentation IP TTL (Time to Live) Objective 1.04 – Explaining the functionality and features of technologies and protocols specific to the transport layer MTU / MSS TCP Functionality TCP Connection Setup by Virtual Server Type TCP Profile Settings (Tunables) UDP Functionality UDP Profile Settings (Tunables) TCPDUMP on F5 Objective 1.05 – Explaining the functionality and features of technologies and protocols specific to the application layer Application Layer Traffic Management on F5 HTTP Functionality HTTP Status Codes HTTP Headers F5 HTTP White Paper DNS Functionality DNS Record Types SIP Functionality F5 SIP White Paper FTP Functionality SMTP Functionality HTTP Cookies My Name is URL Section 2 – F5 Solutions and Technology In this section, we would be gaining into the actual F5 Solutions. Most engineers taking this exam would be experiencing with LTM and iRules, but little else. Hopefully, the familiarity gained from the F5 datasheets as well as white papers which would be shown at their web pages and would help you to understand the breadth of the F5 offerings. You would be preparing to take the first step into a larger world. This section would be also worth 33% of the total test score. Objective 2.01 – Articulating the role of F5 products Access Policy Manager (APM) Application Security Manager (ASM) Local Traffic Manager (LTM) Global Traffic Manager (GTM) Enterprise Manager (EM) WAN Optimization Manager (WOM) Web Accelerator ARX File Virtualization F5 White Papers F5 Datasheets Objective 2.02 – Explaining the purpose, advantages, and use of iRules iRule Wiki (Requires Devcentral Login) Objective 2.03 – Explaining the purpose, advantages, and use of apps iApp Wiki (Requires Devcentral Login) Objective 2.04 – Explaining the purpose, advantages, and use of iControl iControl Wiki (Requires Devcentral Login) Objective 2.05 – Explaining the function of and utilize cases for full proxy and packet-based architectures/packet forwarding.
