Fortinet NSE8_812 Exam - Topic 1 Question 14 Discussion

Actual exam question for Fortinet's NSE8_812 exam

Question #: 14
Topic #: 1

Refer to the exhibits.

A customer has deployed a FortiGate with iBGP and eBGP routing enabled. HQ is receiving routes over eBGP from ISP 2; however, only certain routes are showing up in the routing table-Assume that BGP is working perfectly and that the only possible modifications to the routing table are solely due to the prefix list that is applied on HQ.

Given the exhibits, which two routes will be active in the routing table on the HQ firewall? (Choose two.)

A172.16.204.128/25

B172.16.201.96/29

C172,620,64,27

D172.16.204.64/27

Show Suggested Answer

Suggested Answer: B, D, E

Bmust be set to enable mode-cfg, which is required for injecting IKE routes on the ADVPN shortcut tunnels.

Dmust be set to enable add-route, which is the command that actually injects the IKE routes.

Emust be set to enable mode-cfg-allow-client-selector, which allows custom phase 2 selectors to be configured.

The other options are incorrect. Option A is incorrect because net-device disable is not required for injecting IKE routes on the ADVPN shortcut tunnels. Option C is incorrect because IKE version 1 is not supported for ADVPN.

I feel like I should be able to eliminate one of the options based on the prefix list, but I can't recall the specifics right now.

I’m a bit confused about the subnet masks. I think I need to double-check how they affect route selection in BGP.

This question feels similar to one we practiced where we had to identify active routes based on prefix lists. I think I might lean towards A and D.

I remember studying prefix lists and how they filter routes, but I'm not entirely sure which ones are allowed here.

I'm feeling pretty confident about this one. The prefix list information seems straightforward, and I know BGP routing well, so I should be able to nail this.

Okay, I think I've got this. The key is to focus on the prefix list and which routes it will allow through. I'll work through the options methodically.

This looks like a tricky BGP routing question. I'll need to carefully review the prefix list details to determine which routes will be active.

Wait, did they accidentally include a picture of a cat instead of the actual routing table? I'm starting to doubt the validity of this entire question.

So, the picture of the cat is just a distraction. Focus on the routing table information provided.
