20+ practice questions focused on BIG-IP Local Traffic Manager — one of the most tested topics on the F5 Certified Technology Specialist: BIG-IP LTM exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start BIG-IP Local Traffic Manager PracticeAn LTM Specialist notices that a virtual server using a Cookie Insert persistence profile is not correctly maintaining session affinity for users. The application serves content over HTTPS and uses secure cookies. What must be configured to ensure persistence functions correctly?
Explanation: Persistence using Cookie Insert relies on the client returning the cookie provided by the BIG-IP. Because the application uses Secure cookies, the BIG-IP must be configured to match those security attributes. If the cookie is flagged as Secure but the persistence profile does not reflect this, the browser will ignore the set-cookie header, resulting in persistence failure. This is critical in load balancing environments where session state is maintained on specific backend pool members.
An LTM Specialist needs to ensure that all traffic sent to a specific virtual server is logged for auditing purposes. Which method is most efficient for capturing detailed request and response information without significantly degrading performance?
Explanation: High-speed logging (HSL) is the recommended way to log traffic on BIG-IP. Unlike older logging methods that rely on local syslog, HSL sends logs to a remote collector over a dedicated, non-blocking path. This prevents the BIG-IP's management processor from becoming a bottleneck, ensuring that auditing requirements are met without impacting the performance of the data plane or the availability of the application services.
Which THREE conditions must be met for a SNAT to be used by a virtual server to translate the source IP address of outbound traffic?
Explanation: SNAT is necessary when the server cannot route directly back to the client, or when the server needs to see a consistent source IP for policy reasons. The virtual server must be configured with a SNAT type (either Automap or a specific SNAT pool), the BIG-IP must be in the traffic path for both directions, and the packet must be traversing the BIG-IP as a full proxy. If any of these are missing, the SNAT will not engage.
An LTM administrator needs to ensure that client requests are consistently mapped to the same backend server based on the source IP address for a duration of 30 minutes. Which persistence method should the administrator configure?
Explanation: Source Address Affinity persistence, also known as sticky persistence, is the correct mechanism here. It uses the client's source IP address to map the session to a specific pool member. By setting the timeout to 1800 seconds, the BIG-IP ensures the mapping persists for exactly 30 minutes. This is critical for applications requiring session state continuity without cookie support or specific application headers.
Refer to the exhibit. An LTM administrator observes that 10.1.1.5 is marked as 'disabled'. How will this affect traffic flow for existing and new connections to the virtual server associated with this pool?
Explanation: When a pool member is marked as disabled, the BIG-IP stops sending new connections to that member while allowing existing connections to complete if persistence or connection mirroring is active. This state differs from 'down' which implies a health monitor failure. Understanding these states is vital for graceful maintenance procedures without dropping active user sessions abruptly during server rotation or patching cycles.
