Which type of OSPF area makes use of LSA type 7s?
- backbone
- stub
- not-so-stubby
- totally stubby
Explanation: When an OSPF not-so-stubby area (NSSA) is implemented, external routes are allowed to travel through a stub area that has other external routes prohibited. The way this is accomplished is through the use of type 7 LSAs which are used to carry the external routes across the stub area, but still keep other type 5 external routes out of the area. When the type 7 LSAs reach the ABR for the stub area, the ABR changes these LSAs to type 5s for transmission through the rest of the OSPF areas that allow type 5 LSAs.
