Why each option
HSRP uses a specific virtual MAC address format, and for group 15, the default virtual MAC address is 00:00:0c:07:ac:0f.
This MAC address does not follow the standard HSRP virtual MAC address format of 00:00:0C:07:AC:XX.
This MAC address does not follow the standard HSRP virtual MAC address format of 00:00:0C:07:AC:XX.
The HSRP virtual MAC address format is 00:00:0C:07:AC:XX, where XX is the HSRP group number in hexadecimal. For group 15 (decimal), which is 0F in hexadecimal, the MAC address becomes 00:00:0C:07:AC:0F.
This MAC address does not follow the standard HSRP virtual MAC address format of 00:00:0C:07:AC:XX, as the last octet does not correctly represent group 15 in hexadecimal.
