Question

In HSRP version 1, which part of the virtual MAC address identifies the HSRP group number?

a) AC
b) 0C
c) 00
d) 07
e) 0B

Answer 1

In HSRP version 1, the part of the virtual MAC address that identifies the HSRP group number is 'AC'. The fixed part of the address includes 0000.0C07.AC, followed by the group number in hexadecimal format.

Step-by-step explanation:

In HSRP version 1, the virtual MAC address is composed of the fixed part 0000.0C07.ACxx, where 'xx' is the HSRP group number in hexadecimal format. Thus, the part of the virtual MAC address that identifies the HSRP group number is 'AC'. Each HSRP group on a network interface has a unique MAC address and group number. The routers in the HSRP group can then use this virtual MAC address for the virtual IP address and provide failover capabilities.
