Objectives
- Build a reliable mental model of how BIG-IP LTM processes traffic from virtual server to pool member, including selection logic and health decisions.
- Diagnose pool and monitor failures using evidence, separating configuration issues from runtime conditions and network reachability problems.
- Apply SNAT and translation strategies correctly, predict side effects, and restore traffic in environments with asymmetric routing constraints.
- Select and tune LTM profiles with clear intent, understanding how TCP, HTTP, OneConnect, and related profiles shape behavior and performance.
- Engineer persistence correctly for real applications, avoiding sticky-session mistakes that cause uneven load, user disruption, or hidden failures.
- Operate SSL offload safely by reasoning through certificates, chains, client-side and server-side profiles, and common handshake failure patterns.
- Use iRules for practical, controlled outcomes such as header and URI handling, while avoiding unsafe event choices and performance traps.
- Execute troubleshooting playbooks under pressure by choosing the best next diagnostic step and validating a fix without collateral impact.
Pre Requisites
- Basic understanding of networking fundamentals (IP addressing, ports, and routing) and comfort reading simple traffic flow diagrams.
- Familiarity with web application concepts such as HTTP requests and responses, cookies, and session behavior will help you move faster.
- Access to a BIG-IP lab is helpful but not required; the practice tests are designed to train reasoning and operational decision-making.
- A willingness to think in cause-and-effect terms, not “settings lists,” because the course focuses on outcomes, evidence, and safe changes.
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
