350-401 · Question #575

Refer to the exhibit. After configuring HSRP an engineer enters the show standby command. Which two facts are derived from the output? (Choose two.)

The correct answer is B. If Fa0/0 is shut down, the HSRP priority on R2 becomes 80 E. R2 is using the default HSRP hello and hold timers.. The show standby output confirms that R2's HSRP priority is configured to decrement to 80 if its Fa0/0 interface goes down, and it is currently operating with the default HSRP hello (3s) and hold (10s) timers.

Why each option

The `show standby` output confirms that R2's HSRP priority is configured to decrement to 80 if its Fa0/0 interface goes down, and it is currently operating with the default HSRP hello (3s) and hold (10s) timers.

AThe router with IP 10.10.1.3 is active because it has a higher IP address

While 10.10.1.3 is likely the Active router, HSRP determines active status primarily based on configured priority, with a higher IP address only serving as a tie-breaker when priorities are equal.

BIf Fa0/0 is shut down, the HSRP priority on R2 becomes 80Correct

The HSRP output would show a tracking configuration like `track interface Fa0/0 decrement 20`, meaning if Fa0/0 goes down, R2's priority will be reduced by 20 from its configured value (e.g., from 100 to 80), potentially causing a failover.

CR2 Fa1/0 regains the primary role when the link comes back up

The output of `show standby` explicitly indicates whether `Preempt enabled` or `Preempt disabled`; without preemption enabled, R2 would not automatically regain the primary role even if the link comes back up.

DR2 becomes the active router after the hold time expires.

R2 (the standby router) becomes the active router immediately if the current active router fails or its priority drops below R2's (and preemption is enabled), it does not wait for the hold time to expire.

ER2 is using the default HSRP hello and hold timers.Correct

The default HSRP hello timer is 3 seconds and the default hold timer is 10 seconds. The `show standby` command output displays these timer values, allowing confirmation of whether they are at their defaults or have been modified.
