Refer to the exhibit.
The customer requirements include resilience for branch communications. If anyone link fails, a
branch can still reach the main office servers. In addition either one of the 5920 switches at the
core of the WAN should be able to fail with branches still maintaining their connections.
What should the network architect include in the design to meet this requirement?
A.
A connection directly to an ISP to each branch router, which also requires the OSPF area to
become a not so stubby area (NSSA)
B.
Virtual Router Redundancy Protocol (VRRP) enabled and configured in the switches in the
5920 IRF group
C.
Graceful restart on the 5920 IRF group in standard IETF mode
D.
A floating static route on the branch switches to the 5920 IRF group in case the OSPF solution
fails
can any one help plesae ?
what is th right answer ?

Answer: C
OSPF graceful restart, on the other hand, enables the IRF virtual switch to ask its neighbors to maintain the neighbor and/or adjacency relationship undisturbed while the new Master restarts the OSPF process. Thus traffic continues toward its destination undisturbed.
