Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
service_prefix "*" { policy = "write" }
Why it's wrong here
Write access is not required for discovery.

agent_prefix "" { policy = "read" }
Why it's wrong here
Agent read is for local agent status.

acl_prefix "" { policy = "read" }
