Show Suggested Answer Hide Answer
Suggested Answer: B

Option B configures area 7 as a not-so-stubby area (NSSA) with theno-summaryoption on the area border router (ABR) R4. This allows the injection of external routes from EIGRP into the OSPF domain as type 7 LSAs, while preventing the propagation of inter-area summary LSAs into area 7.Theno-summaryoption also generates a default summary route for area 7, which can be used by R9 to reach the internet2.

Option A configures area 7 as a stub area, which does not allow any external routes or type 7 LSAs in the area.This prevents R9 from learning the EIGRP routes and accessing the internet3.

Option C configures area 7 as a NSSA without theno-summaryoption on R4. This allows the injection of type 7 LSAs into the area, but also allows the propagation of inter-area summary LSAs into the area.However, this option does not generate a default summary route for area 7, which means R9 has no route to reach the internet4.

Option D configures area 7 as a NSSA with thedefault-information originateoption on R4. This allows the injection of type 7 LSAs into the area, but also allows the propagation of inter-area summary LSAs into the area. Thedefault-information originateoption generates a type 7 default route for area 7, which can be used by R9 to reach the internet.However, this option is redundant and less efficient than Option B, because it injects both a type 3 and a type 7 LSA for the default route into the area5.

I recall that limiting LSAs can impact connectivity, so I’m leaning towards Option A, but I’m not completely confident about it.

I feel like Option D could be the right choice since it seems to cover all the necessary LSA types, but I need to double-check the configurations.

I think it might be Option B because it allows for type 1 and 2 LSAs, but I’m a bit confused about the type 7 requirement.

I remember we practiced a similar question about LSA types, but I’m not sure which option specifically restores internet access.

Okay, I think I've got a handle on this. The key is to identify the configuration that allows only LSA types 1, 2, and 7, while also restoring connectivity for users on R9. I'll carefully compare the options to find the right solution.

This looks like a tricky OSPF configuration question. I'll need to carefully review the exhibit and options to determine which configuration restores internet access while only allowing the specified LSA types.
