In which scenarios would a LAN subnet configured with two routers configured with HSRP lose off subnet communications when one of the routers failed?
A) HSRP version mismatch
B) Routers configured with different virtual IPs
C) ACL blocking HSRP packets
D) HSRP group number mismatch
B
Explanation: B) If HSRP routers are configured with different virtual IP addresses, they would communicate and seem to work correctly until the initial router fails. When this happens, the virtual IP address configured on the secondary router would be used, causing any devices configured with the initial router's Virtual IP address to lose off subnet communications.
