Refer to the exhibit.

Refer to the exhibit Networks 172.16.31.0/24 and 172 16 30.0/24 are advertised in area 34. and network 172.22 10.0/24 is advertised in area 0. A recent security review discovered that users connected to routers R1 and R2 have been making unauthorized access to an application running on network 172 16 31 0/24 An engineer determined that routers R1 and R2 are receiving updates for network 17 16 31 0/24 Which action resolves the issue?

Wait, why only R3? That seems risky.

Definitely agree, R1 and R2 need that filtering!

I think route filtering on R3 and R4 is the way to go.

Applying filtering on R4 alone won't solve the issue.

I’m a bit confused about whether R4 alone would be enough. I think I need to double-check how route updates work in this scenario.

I feel like I read that filtering should be done on the routers directly connected to the affected networks, so maybe R1 and R2?

This question seems similar to one we practiced where we had to filter routes to prevent unauthorized access. I think applying it on R3 might be the right move.

I remember something about route filtering, but I'm not sure if it should be applied to both R3 and R4 or just one of them.

Ah, I see. The key here is to identify the source of the unauthorized access and apply the filtering at the appropriate routers. I'll need to carefully consider the options and make sure I understand the implications of each before selecting the best answer.

Based on the information provided, I think the best solution is to apply route filtering on routers R3 and R4. That way, we can prevent the unauthorized access from the users connected to R1 and R2 without disrupting the legitimate routing updates.

I'm a bit confused here. The question mentions networks in different areas, so I'll need to understand the OSPF area structure and how that affects the routing updates. Maybe I should start by drawing out the network diagram to visualize the connections.

Okay, let's see. The issue is with unauthorized access to the 172.16.31.0/24 network, and the routers R1 and R2 are receiving updates for that network. I think the solution might involve applying route filtering on those routers.

Hmm, this looks like a tricky one. I'll need to carefully analyze the network topology and routing information to determine the best approach.

Wait, wait, wait... Isn't this the same problem as the one with the 'unauthorized access' issue in the IT department last year? I swear I've seen this before!

That makes sense, we need to restrict the updates they are receiving.

Hmm, I thought the solution would be to apply route filtering on all the routers, just to be safe. Better safe than sorry, right?
