Discuss Cisco 300-410 Exam Topic 13 Question 99

Refer to the exhibit.

Refer to the exhibit After an engineer modified the configuration for area 7 to permit type 1 2 and 7 LSAs only users connected to router R9 reported that they could no longer access the internet. Which configuration restores internet access to users on R9 and permits only LSA type 1,2, and 7?

AOption A

BOption B

COption C

DOption D

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’m not sure about B, seems off to me.

Xenia 11 months ago

Definitely not A, that won't work!

Lynelle 11 months ago

Wait, why would type 7 LSAs affect internet access?

Talia 11 months ago

I think option C is the right choice!

Dorian 12 months ago

Looks like R9 needs LSA type 5 for internet access.

Iluminada 12 months ago

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.

Theodora 1 year ago

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.

Corinne 1 year ago

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

Christiane 1 year ago

I'm feeling pretty confident about this one. The exhibit and options provide enough information for me to determine the correct configuration that meets the stated requirements.

Mayra 1 year ago

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.

Elouise 1 year ago

Hmm, I'm a bit confused by the different configurations in the options. I'll need to take some time to analyze each one and understand how they impact the OSPF behavior and internet access.

Bulah 1 year ago

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.

Pearlene 1 year ago

This is a good opportunity to apply my OSPF knowledge. I'll methodically go through the exhibit and options, considering how each configuration would impact the network and internet access.

Option D? No way, that's way off base. I'm going with Option B, it's the clear choice.

Joaquin 2 years ago

Haha, these networking questions can be tricky! But I'm pretty sure Option B is the winner here.

Why do you think Option C is correct?

Hmm, Option A seems a bit too complicated. I'd go with Option B - it's simple and gets the job done.

Let's go with Option B then, it seems like the most straightforward solution.

I think the correct answer is Option B.

Cecil 2 years ago

I think Option C is the way to go. It's the most straightforward configuration that meets the requirements.

Malinda 2 years ago

Option B looks like the right answer to me. It permits only the LSA types specified and should restore internet access to users on R9.

Britt 2 years ago

↳ replying to Malinda

I also believe that Option B is the correct configuration to allow only specific LSA types and restore internet access for users on R9.

Valentin 2 years ago

↳ replying to Malinda

Option B looks like the most suitable answer for this scenario.

Francine 2 years ago

↳ replying to Malinda

I think Option B is the best option to restore internet access for users on R9.
