QUESTION 352
A financial services company runs HSRP at the edge of its network to allow for redundancy for the default gateway for its servers. The CTO of the company is concerned that the failover time for HSRP is too slow and a different mechanism should be used.

Which option is the fastest down detection and failover solution for this HSRP environment?
A. Limit the Layer 2 broadcast domain.
B. Decrease the HSRP timers.
C. Implement BFD.
