Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Stub areas filtering out external LSA advertisements
Why it's wrong here
Stub areas filter summary/external LSAs and do not dictate the creation of Type 2 LSAs.
- ✗
Virtual links traversing a non-backbone transit area
Why it's wrong here
Virtual links are modeled as point-to-point links using Type 1 LSAs.
- ✗
Point-to-point links between two directly connected routers
Why it's wrong here
Point-to-point links use Type 1 Router LSAs only and do not require a DR or Type 2 LSAs.
- ✓
Multi-access broadcast segments with an active Designated Router
Why this is correct
Type 2 Network LSAs are generated by the DR for multi-access networks.
