Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AS_PATH is a well-known mandatory attribute.
Why this is correct
Correct: AS_PATH is well-known mandatory; it is always included in BGP updates and is used for loop prevention and path selection.
- ✓
LOCAL_PREF is a well-known discretionary attribute.
Why this is correct
Correct: LOCAL_PREF is well-known discretionary; it is recognized by all BGP speakers but may or may not be included in updates, and it influences outbound traffic.
- ✗
MED is an optional transitive attribute.
Why it's wrong here
Incorrect: MED is optional non-transitive; it is not passed to other ASes and is used to influence inbound traffic.
- ✗
ORIGIN is a well-known discretionary attribute used for loop prevention.
Why it's wrong here
Incorrect: ORIGIN is well-known mandatory, not discretionary, and it indicates the origin of the route (IGP, EGP, or incomplete), not used for loop prevention.
- ✗
NEXT_HOP is an optional non-transitive attribute.
Why it's wrong here
Incorrect: NEXT_HOP is well-known mandatory, not optional non-transitive; it specifies the next-hop IP address to reach a prefix.
