Which first-hop redundancy solution listed would supply Company clients with MAC address
0000.0C07.AC0A for group 10 in response to an ARP request for a default gateway?

A.
IRDP

B.
Proxy ARP

C.
GLBP

D.
HSRP

E.
VRRP

F.
IP Redirects

Explanation:
HSRP is a Cisco-proprietary protocol developed to allow several routers (or multilayer
switches) to appear as a single gateway IP address. RFC 2281 describes this protocol in
more detail.
Each router keeps a unique MAC address for its interface. This MAC address is always
associated with the unique IP address configured on the interface. For the virtual router
address, HSRP defines a special MAC address of the form 0000.0c07.acxx, where xx
represents the HSRP group number as a two-digit hex value. For example, HSRP Group 1
appears as 0000.0c07.ac01, HSRP Group 16 appears as 0000.0c07.ac10, and so on.
