You have a BGP session between two routers. You have enabled BFD on the interface and configured 'bfd-liveness-detection' under the BGP neighbor. The BFD session is up, but BGP is not using BFD for failure detection. What is the most likely cause?

The BFD session is not associated with the BGP session because the BFD configuration is missing the 'version' statement.

The BFD minimum interval is too high.

The BGP session is not using the same interface as the BFD session.

What is the purpose of VRRP interface tracking?

To track the number of VRRP advertisements received from the master

To track the routing table for a specific route

To track the MAC address of the master router

To monitor the state of an interface and adjust the VRRP priority if the interface goes down

How does BFD detect a failure in the forwarding path?

By monitoring the interface link state and reporting changes to the routing protocol

By sending a broadcast message to all routers in the network and waiting for an acknowledgment

By sending periodic control packets and expecting a reply within a negotiated interval

By using the routing protocol's hello timer to determine if the peer is still reachable

How is a BFD session maintained once it is in the Up state?

By using the routing protocol's hello packets

By sending a single control packet and then waiting for a failure

By exchanging control packets at the negotiated interval

By monitoring the interface link state

Part of the High Availability domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 30 practice questions to prepare you well beyond it.
