Cisco FabricPath is implemented in a data center. You plan lo implement anycast HSRP. What is an advantage of anycast HSRP as compared HSRPv2?

Options

Why each option

Anycast HSRP, when deployed with Cisco FabricPath, provides the advantage of allowing up to four HSRP gateways to simultaneously forward traffic for the same virtual IP address and MAC address. This enables active-active load sharing for first-hop redundancy, enhancing network efficiency compared to traditional HSRPv2.

AUp to four HSRP gateways can forward traffic simultaneously.Correct

Anycast HSRP, particularly when integrated with FabricPath, allows up to four HSRP-enabled Layer 3 gateways to actively forward traffic for the same virtual IP and MAC address, providing active-active load sharing and improved resource utilization.

BHSRP gateways use BFD for faster failure detection

HSRPv2 can also leverage Bidirectional Forwarding Detection (BFD) for faster failure detection, so this is not a unique advantage of Anycast HSRP.

CAn HSRP group can be secured by using MD5.

HSRPv2 supports MD5 authentication to secure HSRP groups, making this a common feature rather than an exclusive advantage of Anycast HSRP.

DUp to six HSRP gateways can forward traffic simultaneously.

The typical maximum number of simultaneous forwarding gateways with Anycast HSRP is four, not six.
