QUESTION NO: 1
A company plans to include Nonstop
Forwarding and Bidirectional Forwarding Detection as a part of their network
redundancy plan. In which two ways do NSF and BFD work together when different
hardware platforms are compared? (Choose two.)
A. During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform.
B. At some hardware
platforms, BFD and NSF are not supported together. During supervisor engine or
routing engine failover, the BFD at the peer router will trigger a link down.
C. To ensure that BFD at
the peer router will not trigger a link down during NSF, the BFD packets must
be processed fast enough, and, during supervisor engine or routing engine
failover, by processing the BFD independent from the supervisor engine or
routing engine.
D. Because BFD is always
processed at the line cards (not at the supervisor engine or routing engine), a
supervisor engine or routing engine failover will not affect the BFD peer
router.
E. Because BFD is always
processed at the supervisor engine or routing engine, a supervisor engine or
routing engine failover will always trigger a link down at the peer router.
Answer: B, C
