Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
show security flow session summary
Why it's wrong here
Summary only shows aggregate counts, not direction or interface details per session.
- ✓
show security flow session detail
Why this is correct
Detailed session output reveals interface mappings, NAT states, and flow directions necessary for diagnosing asymmetric routing.
- ✗
show security flow node 0 session
Why it's wrong here
While node specification is used in Chassis Clusters, show security flow session detail is the primary granular display command.
- ✗
show security flow session interface
Why it's wrong here
This command does not exist.
