101 Question #30: Real Exam Question with Answer & Explanation
The correct answer is D: It can be done by assigning one monitor to the pool and a different monitor to the slower pool. In F5 BIG-IP, a pool member can be assigned its own monitor that overrides the pool-level monitor, enabling different check intervals per member.

Question
You have a pool of servers that need to be tested. All of the servers but one should be tested every 10 seconds, but one is slower and should only be tested every 20 seconds. How do you proceed.
Options
- AIt cannot be done. All monitors test every five seconds.
- BIt can be done, but will require assigning monitors to each pool member.
- CIt cannot be done. All of the members of a pool must be tested at the same frequency.
- DIt can be done by assigning one monitor to the pool and a different monitor to the slower pool
Explanation
In F5 BIG-IP, a pool member can be assigned its own monitor that overrides the pool-level monitor, enabling different check intervals per member.
Common mistakes.
- A. The monitoring interval is a configurable parameter on each monitor object and is not fixed at five seconds.
- B. Assigning individual monitors to every pool member is not required - a single pool-level monitor combined with one member-level override is sufficient to achieve different intervals.
- C. Pool members are not required to share the same monitoring frequency because a monitor assigned directly to a pool member overrides the pool-level assignment for that member only.
Concept tested. F5 BIG-IP per-pool-member monitor override assignment
