Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
All routes from neighbor 10.0.0.1 are permitted; routes with tag 100 have their tag changed to 200.
The route-map SETTAG has two permit sequences. Sequence 10 matches routes with tag 100 and sets the tag to 200. Sequence 20 is a catch-all permit with no match or set statements. Routes from neighbor 10.0.0.1 that have tag 100 will have their tag changed to 200; all other routes are permitted unchanged. No routes are filtered.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
All routes from neighbor 10.0.0.1 are permitted; routes with tag 100 have their tag changed to 200.
Why this is correct
Correct. Sequence 10 changes the tag for routes with tag 100; sequence 20 permits all others.
- ✗
Routes with tag 100 are denied; all other routes are permitted.
Why it's wrong here
Incorrect. The route-map has permit sequences, so routes with tag 100 are permitted but have their tag changed.
- ✗
Only routes with tag 100 are permitted; all other routes are denied.
Why it's wrong here
Incorrect. Sequence 20 is a catch-all permit, so all routes are permitted.
- ✗
The route-map is misconfigured because sequence 20 has no match statement; it should have a match any statement.
Why it's wrong here
Incorrect. A permit sequence with no match statement matches all routes; it is a valid catch-all.
