• Question 113:

  On a Cisco Nexus 7000 Series router, which statement about HSRP and VRRP is true?

  A. When VDCs are in use, only VRRP is supported.
  B. HSRP and VRRP both use the same multicast IP address with different port numbers.
  C. HSRP has shorter default hold and hello times.
  D. The VRRP group IP address can be the same as the router-specific IP address.
  D. The VRRP group IP address can be the same as the router-specific IP address.

  VRRP allows for transparent failover at the first-hop IP router by configuring a group of routers to share a virtual IP address. VRRP selects a master router in that group to handle all packets for the virtual IP address. The remaining routers are in standby and take over if the master router fails.
