F5-303 study plan

F5-303 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Application Delivery and Security Platform fundamentals & BIG-IP platform configuration and traffic management

  • Map the full request path through a BIG-IP: client VLAN, virtual server, iRule event, pool member selection, and server-side connection, drawing it from memory by week's end

  • Distinguish the roles of virtual server, pool, pool member, node, monitor, and profile, and state which object owns persistence, SSL termination, and health checking

  • Configure a working HTTP virtual server with a load-balancing pool of at least two members and one health monitor on a lab or trial instance

  • Explain the difference between a standard virtual server, a forwarding virtual server, and a performance L4 virtual server, and pick the right one for three described traffic scenarios

Your checkpoint

A one-page hand-drawn or digital request-flow diagram plus a lab screenshot showing a green pool with two healthy members

Week 2

BIG-IP platform configuration and traffic management & Application Delivery and Security Platform fundamentals

  • Configure and verify load-balancing methods (round robin, least connections, ratio, and priority group activation) and predict member selection for a given member state

  • Set up a health monitor tuned to an application endpoint and demonstrate the pool draining a member after a forced failure

  • Implement source-address persistence and cookie persistence, then articulate when each is appropriate and how they interact with SSL offload

  • Describe how profiles (TCP, HTTP, client SSL, server SSL) layer onto a virtual server and modify traffic without an iRule

Your checkpoint

A test report showing before/after pool member status when a monitor fails, with the persistence method that kept a client session pinned

Week 3

BIG-IP platform configuration and traffic management & Troubleshooting, monitoring, and operations

  • Configure SNAT and a SNAT pool, then confirm the source address seen by a backend server using a capture or server log

  • Build a simple iRule that logs a header and redirects based on URI, and explain which events fire in what order for one request

  • Compare one-connect, auto last hop, and SNAT behavior and select the correct choice for a topology where the pool member's default gateway is not the BIG-IP

  • Use tcpdump on the BIG-IP to prove whether traffic is being SNATed and whether the return path is symmetric

Your checkpoint

An iRule file plus a packet capture excerpt proving the SNAT address used toward the backend

Week 4

Application security and web application firewall & BIG-IP platform configuration and traffic management

  • Explain the WAF processing pipeline from virtual server through the security policy to the backend, including where attack signatures, parameters, and bot defense sit

  • Create a security policy in transparent/learning mode, generate traffic against a deliberately vulnerable test app, and read the resulting violations

  • Tune a false positive by disabling or relaxing a specific signature or parameter and record the rationale

  • Distinguish a signature-based violation from a violation raised by a negative-security or parameter enforcement setting

Your checkpoint

A tuning log listing at least three violations found in learning mode with the exact change made and why

Milestones

Week 4: Can you draw the request path, name the object that owns each function, and explain one WAF violation you personally tuned, without notes? If not, redo week 1 and week 4 goals before moving on.
