Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
then { deny; log; }
Why this is correct
Adding the 'log' modifier to a deny action ensures traffic drops are recorded in the security log.
- ✗
then { permit; trace; }
Why it's wrong here
'trace' is used for packet tracing/debugging, not standard security policy logging.
- ✗
then { reject; syslog-immediate; }
Why it's wrong here
'syslog-immediate' is not a valid Junos policy action modifier.
- ✗
then { drop; audit-trail; }
Why it's wrong here
'audit-trail' is not a valid policy logging keyword.
