Bidirectional Forwarding Detection (BFD) JN0-281 Practice Questions (Page 1)
Part of the High Availability domain, which makes up ~21% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–13 in this domain), expect 1–3 from this objective — we provide 25 practice questions to prepare you well beyond it.

A service provider runs BFD in asynchronous mode between two routers over a high-utilization link. They notice that BFD sessions are flapping due to packet loss. They want to reduce the sensitivity to packet loss while keeping the detection time under 1 second. The current transmit interval is 200 ms and the detection multiplier is 3. What should they do?

A data center network uses OSPF for routing between leaf and spine switches. The network team wants to improve convergence time after a link failure. They decide to enable BFD on the OSPF interfaces. What is the primary benefit of using BFD with OSPF in this scenario?
