Based on the debug output, which three statements about HSRP are true? (Choose three.)
A.
The final active router is the router with IP address 172.16.11.111.
B.
The router with IP address 172.16.11.111 has preempt configured.
C.
The priority of the router with IP address 172.16.11.112 is preferred over the router with
IP address 172.16.11.111.
D.
The IP address 172.16.11.11 5 is the virtual HSRP IP address.
E.
The router with IP address 172.16.11.112 has nonpreempt configured.
F.
The router with IP address 172.16.11.112 is using default HSRP priority.
Explanation:
Each router in an HSRP group has its own unique IP address assigned to an interface. This
address is used for all routing protocol and management traffic initiated by or destined to the
router. In addition, each router has a common gateway IP address, the virtual router
address, that is kept alive by HSRP. This address is also referred to as the HSRP address or
the standby address. Clients can point to that virtual router address as their default gateway,
knowing that a router always keeps that address active. Keep in mind that the actual
interface address and the virtual (standby) address must be configured to be in the same IP
subnet. You can assign the HSRP address with the following interface command:
Switch(config-if)# standby group ip ip-address [secondary]
When HSRP is used on an interface that has secondary IP addresses, you can add the
secondarykeyword so that HSRP can provide a redundant secondary gateway address.
You can configure a router to preempt or immediately take over the active role if its priority is
the highest at any time. Use the following interface configuration command to allow preemption:
Switch(config-if)# standby group preempt [delay seconds]
By default, the router can preempt another immediately, without delay. You can use the
delay keyword to force it to wait for seconds before becoming active. This is usually done if
there are routing protocols that need time to converge.
