Q1Domain Verified
In OSPF, what is the primary function of the Type 3 LSA (Summary LS
To provide information about external routes learned via redistribution.
generated by an ABR? A) To advertise intra-area routes within a single OSPF area.
To advertise inter-area reachability information from one OSPF area to another.
To summarize routes from a stub area into the backbone area.
Q2Domain Verified
Consider an OSPF network with multiple virtual links configured to connect non-contiguous backbone areas. If a virtual link's transit area becomes isolated from the backbone (e.g., due to a router failure), what is the most likely impact on the virtual link's adjacency?
The virtual link will be automatically converted into a normal backbone area connection.
The virtual link adjacency will transition to a 'Down' state, and OSPF will attempt to re-establish it.
The virtual link will continue to function, but with reduced OSPF flooding efficiency.
The virtual link adjacency will remain operational as long as the transit area routers can reach each other.
Q3Domain Verified
A network administrator is troubleshooting a scenario where OSPF routes are not being learned correctly between two areas. They observe that the ABR is generating Type 3 LSAs, but these LSAs are not propagating to the other are
What is a potential specialist cause for this issue, beyond a simple link failure? A) The ABR is configured with a higher OSPF router ID than the designated router in the destination area.
The ABR is configured with the `area <area-id> stub` command, and the destination area is not a stub area.
The ABR has a passive interface configured for the link leading to the destination area.
The transit area for the virtual link connecting the two areas has a different OSPF network type than the backbone area.
