Refer to the exhibit. An engineer is installing a new pair of routers in a redundant configuration.
Which protocol ensures that traffic is not disrupted in the event of a hardware failure?

  • A. HSRPv1
  • B. GLBP
  • C. VRRP
  • D. HSRPv2
Answer: Option A.
Explanation: 

The “virtual MAC address” is 0000.0c07.acXX (XX is the hexadecimal group number) so it is using HSRPv1. HSRP Version 2 uses a new MAC address which ranges from 0000.0C9F.F000 to 0000.0C9F.FFFF.
