Refer to the exhibit. Assume that Switch_A is active for the standby group and the standby devicehas only the default HSRP configuration. What conclusion is valid？（）
A.If port Fa1/1 on Switch_A goes down， the standby device will take over as active
B.If the current standby device were to have the higher priority value， it would take over the role ofactive for the HSRP group
C.If Switch_A had the highest prioritynumber， it would not take over as active router
D.If port Fa1/1 on Switch_A goes down， the new priority value for the switch would be 190
Network topology exhibit：
In this network segment， the two routers on the network are configured for GLBP （Gateway LoadBalancing Protocol）. What can be said about this？（）
A.The hosts will have different default gateway IP addresses and different MAC addresses foreach rtouter
B.The default gateway address of each host should be set to the virtual IP address
C.The hosts will learn the proper default gateway IP address from Router R1
D.The default gateway address of each host should be set to the real IP address of the router
E.None of the other alternatives apply
Refer to the exhibit. Which three statements accurately describe this GLBP topology？（）
A.Router A is responsible for answering ARP requests sent to the virtual IP address.
B.If Router A becomes unavailable， Router B will forward packets sent to the virtual MAC addressof Router A
C.If another router were added to this GLBP group， there would be two backup AVGs
D.Router B is in GLBP listen state
E.Router A alternately responds to ARP requests with different virtual MAC addresses
F.Router B will transition from blocking state to forwarding state when it becomes the AVG
Routers R1 and R2 are configured for HSRP as shown below：

standby 35 ip 20.6.2.21
standby 35 priority 100
interface ethernet 1
ip address 20.6.1.1.2 255.255.255.0

D.failure to set the command standby 35 preempt
A.It can be used to block bulk encryption attacks
B.It can be used to protect against denial of service attacks
