Which four statements about this GLBP topology are true? (Choose four.)
A.
Router A is responsible for answering ARP requests sent to the virtual IP address.
B.
If router A becomes unavailable, router B forwards packets sent to the virtual MAC
address of router A.
C.
If another router is 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 transitions from blocking state to forwarding state when it becomes the AVG.
Explanation:
With GLBP the following is true:
With GLB, there is 1 AVG and 1 standby VG. In this case Company1 is the AVG and
Company2 is the standby. Company2 would act as a VRF and would already be forwarding
and routing packets. Any additional routers would be in a listen state.
As the role of the Active VG and load balancing, Company1 responds to ARP requests with
different virtual MAC addresses.
In this scenario, Company2 is the Standby VF for the VMAC 0008.b400.0101 and would
become the Active VF if Company1 were down.
As the role of the Active VG, the primary responsibility is to answer ARP requests to the
virtual IP address.
As an AVF router Company2 is already forwarding/routing packetsReference:
