[All FCSS_EFW_AD-7.4 Questions]

Refer to the exhibit.

An administrator is deploying a hub and spokes network and using OSPF as dynamic protocol.

Which configuration is mandatory for neighbor adjacency?

ASet bfd enable in the router configuration

BSet network-type point-to-multipoint in the hub interface

CSet rfc1583-compatible enable in the router configuration

DSet virtual-link enable in the hub interface

Show Suggested Answer

Suggested Answer: B

In a hub-and-spoke topology using OSPF over IPsec VPNs, the point-to-multipoint network type is necessary to establish neighbor adjacencies between the hub and spokes. This network type ensures that OSPF operates correctly without requiring a designated router (DR) and allows dynamic routing updates across the IPsec tunnels.

Hmm, this looks like a tricky OSPF configuration question. I'll need to carefully review the options and think through the requirements for neighbor adjacency in a hub-and-spoke network.

I'm more of a Pokémon guy, but even I know the answer is B. Point-to-multipoint is the way to go for OSPF on the hub!

Haha, D? What is this, Lord of the Rings? Virtual-link? No way, man. Stick to the basics - B is the one!

A for the win! Setting BFD is crucial for OSPF to detect those failed links. Gotta keep that network up and running!

C is the answer, no doubt. The router config needs to be RFC1583-compatible, everyone knows that!
