A. The local IP address of Router A is 10.1.0.6.
B. The local IP address of Router A is 10.1.0.20.
C. If Ethernet 0/2 goesdown， the standby router will take over.
D. When Ethernet 0/3 of RouterA comes back up， the priority will become 105.
E. Router A will assume the active state if its priority is the highest.

A. Router 172.16.11.112 will be the active router because its HSRP priority is preferred over router 172.16.11.111.
B. Router 172.16.11.111 will be the active router because its HSRP priority is preferred over router  172.16.11.112.
C. The IP address 172.16.11.111 is the virtual HSRP router IP address.
D. The IP address 172.16.11.112 is the virtual HSRP router IP address.
E. The nonpreempt feature is enabled on the 172.16.11.112 router.
F. The preempt feature is not enabled on the 172.16.11.111 router.

A. The router with IP address 172.16.11.111 haspreempt configured.  
B. The final active router is the router with IP address 172.16.11.111.
C. The router with IP address 172.16.11.112 has nonpreempt configured.
D. The priority of the router with IP address 172.16.11.112 is preferred over the router with IP  address 172.16.11.111.
E. The router with IP address 172.16.11.112 is using default HSRP priority.
F. The IP address 172.16.11.115 is the virtual HSRP IP address.

A. Static IP routes are maintained across a switchover because they are configured from entries in  the configuration file.
B. Information about dynamic routing states， maintained on the active supervisor engine， is  synchronized to the redundant supervisor engine and is transferred during the switchover.
C. Information about dynamic routing states， maintained on the active supervisor engine， is not  synchronized to the redundant supervisor engine and is lost on switchover.
D. The Forwarding Information Base （FIB） tables are cleared on a switchover. As a result， routed  traffic is interrupted until route tables reconverge.
E. Static IP routes are cleared across a switchover and recreated from entries in the configuration  file on the redundant supervisor engine.
F. The Forwarding Information Base （FIB） tables are maintained during the switchover. As a  result， routed traffic continues without any interruption when the failover occurs.

A. Only if both tracked objects are up will this router will be available as an AVF for group 1.
B. Only if the state of both tracked objects goes down will this router release its status as an AVF  for group 1.
C. If both tracked objects go down and then one comes up， but the other remains down， this router  will be available as an AVF for group 1.
D. This configuration is incorrect and will not have any effect on GLBP operation.
E. If the state of one tracked object goes down then this router will release its status as an AVF for  group 1.

A. The traffic coming from Host2 is forwarded through router R2 with no disruption. The traffic from  Host1 is dropped due to the disruption of the load balancing feature configured for the glbp group.  
B. The traffic coming from both hosts is temporarily interrupted while the switchover to make R2  active occurs.
C. The traffic coming from Host2 is forwarded through router R2 with no disruption. Host1 sendsan ARP request to resolve the MAC address for the new virtual gateway.
D. The traffic coming from Host1 and Host2 is forwarded through router R2 with no disruption.
