HSRP is running Bet SW A and Dist SW B. Which two links do the switches use to transmit HSRP mess? choose two

The correct answer is E. Distr Switch A, port g4/1 to acc swi, port g1/0/1 F. Distri Switch B, port g4/2 to acc switch, port g2/0/1. HSRP hello messages are sent on the VLAN/subnet where the virtual IP gateway is configured. In a typical campus design, HSRP runs on the distribution layer switches to provide a redundant default gateway for the access layer. The HSRP messages (hellos, active/standby elections)…

Explanation

HSRP hello messages are sent on the VLAN/subnet where the virtual IP gateway is configured. In a typical campus design, HSRP runs on the distribution layer switches to provide a redundant default gateway for the access layer. The HSRP messages (hellos, active/standby elections) are transmitted on the access VLAN links connecting the distribution switches to the access switch. Both Distr Switch A (g4/1) and Distr Switch B (g4/2) send HSRP hellos on those downlinks toward the access switch, where the end hosts reside and the virtual IP is relevant. Core-to-distribution links carry routed traffic, not the access VLAN where HSRP operates.
