detection is reported as quickly as possible to the IGP?
A network design shows two routers directly connected to an Ethernet switch using optical connections. There
is an OSPF adjacency between the routers. In this design, which solution will ensure that interface down
detection is reported as quickly as possible to the IGP?
A. optimized OSPF SPF timers
B. Bidirectional Forwarding Detection
C. automatic protection switching
D. optimized OSPF LSA timers
E. Ethernet OAM CFM monitoring
In which two of these ways can you design this solution? (Choose two
Refer to the exhibit.
A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures betweenSP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.)
A. Enable Y.1731 Connectivity Fault Management on the SP switches.
B. E-LMI PDUs must be forwarded over VPLS.
C. Cisco Discovery Protocol PDUs must be forwarded over the VPLS.
D. Use upward maintenance endpoints on the SP switches.
E. Enable IEEE 802.1ag Connectivity Fault Management on the SP switches.

platforms are compared? (Choose two
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 BFDat 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.
