On a BIG-IP ASM 3600, in standalone mode, which of the following pool configurations is valid?
The correct answer is A. Pool named vs_pool with 1 pool member, no persistence, and no load balancing method. In standalone mode, BIG-IP ASM 3600 supports only a minimal pool configuration with one pool member, no persistence, and no explicitly configured load balancing method.

- CPool named vs_pool with 2 pool members, cookie persistence, and ratio load balancing method
- DPool named vs_pool with 3 pool members, source IP persistence, and least connections load

Why each option
In standalone mode, BIG-IP ASM 3600 supports only a minimal pool configuration with one pool member, no persistence, and no explicitly configured load balancing method.
A standalone BIG-IP ASM deployment does not include full Local Traffic Manager (LTM) capabilities, restricting pool configuration to the most basic form - a single member with no persistence or load balancing method specified. Without LTM, features like cookie persistence and ratio or least-connections load balancing are not available. Option A reflects the only valid configuration for an ASM-only standalone deployment.
Cookie persistence and ratio load balancing are LTM features not available when BIG-IP is running in ASM standalone mode without LTM licensing.
A two-member pool with cookie persistence and ratio load balancing requires full LTM functionality, which is not present in ASM standalone mode.
Source IP persistence and least connections load balancing with multiple pool members require LTM, which is not licensed or available in ASM standalone mode.
