Show Suggested Answer Hide Answer
Suggested Answer: A, D

Ais correct because when an OSPF adjacency is established, a router will advertise a connected network to OSPF neighbors.An OSPF adjacency is a logical relationship between two routers that agree to exchange routing information using the OSPF protocol1.To establish an OSPF adjacency, the routers must be in the same area, have compatible parameters, and exchange hello packets1.Once an OSPF adjacency is formed, the routers will exchange database description (DBD) packets, which contain summaries of their link-state databases (LSDBs)1.The LSDBs include information about the connected networks and their costs2. Therefore, when an OSPF adjacency is established, a router will advertise a connected network to OSPF neighbors through DBD packets.

Dis correct because when a static route to the 224.0.0.5 address is created, a router will advertise a connected network to OSPF neighbors.The 224.0.0.5 address is the multicast address for all OSPF routers3.A static route to this address can be used to send OSPF hello packets to all OSPF neighbors on a network segment3.This can be useful when the network segment does not support multicast or when the router does not have an IP address on the segment3.When a static route to the 224.0.0.5 address is created, the router will send hello packets to this address and establish OSPF adjacencies with other routers on the segment3. As explained above, once an OSPF adjacency is formed, the router will advertise a connected network to OSPF neighbors through DBD packets.

Hmm, I'm a bit confused. If the local device isn't the root bridge, then the root bridge must not have been elected yet. Maybe there's a problem with the network setup?

Wait, isn't the local device the root bridge? The exhibit indicates that the local device has a priority of 4096, which means it's the root bridge for this RSTP topology.

I'm pretty sure the root bridge is using a bridge priority of 4k. The exhibit clearly shows that the root bridge has a priority of 4096, which is equivalent to 4k.
