5. In a new network design, router redundancy is required. One of the routers to be used for
redundancy is not a Cisco router. Which protocol should be implemented to achieve a
redundant configuration?
· Proxy ARP
· HSRP
· VRRP (*)
· VRSP
· GLRP
6. In GLBP operation, which router responds to an ARP request from a host looking for its
default‐gateway MAC address?

7. Of the gateway redundancy protocols that are mentioned, which statement is true?
· GLBP allows multiple routers to participate in a virtual router group that is configured
with a virtual IP address. One member is elected to be the active router for the group
and the other routers are passive until the active router fails.
· By making use of a single virtual IP address and multiple virtual MAC addresses, GLBP
provides load balancing over multiple routers (gateways) . All routers in the virtual
router group participate in forwarding packets. (*)
· By making use of a single virtual IP address and multiple virtual MAC addresses, HSRP
provides load balancing over multiple routers (gateways). All routers in the virtual router
group participate in forwarding packets.
· By making use of a single virtual IP address and multiple virtual MAC addresses, VRRP
provides load balancing over multiple routers (gateways). All routers in the virtual router
group participate in forwarding packets.
8. Which statement is true about Virtual Router Redundancy Protocol (VRRP)?
· The priority value of 255 means the router is ineligible to become the master router.
· The priority value of 255 means the router has stopped participating in VRRP.
· The priority value of 0 means the router has stopped participating in VRRP. (*)
· The priority value of 0 means the router is ineligible to become the master router.
9. In a network where HSRP is properly configured, what MAC address and IP address will be
associated by the end devices with their default gateway?
· the MAC and IP address of the standby router
· the MAC and IP address of the backup router
· the MAC and IP address of the active router
· the IP address of the virtual router and the MAC address of the active router
· the MAC and IP address of the virtual router (*)
10. Refer to the exhibit. Which two statements are true? (Choose two).
· Traffic sharing is being performed on two routers. (*)
· The priority value for HSRP group 1 is the default value.
· The priority value for HSRP group 2 is the default value.
· If the active router for HSRP group 2 goes, down, Router A will take over as active. (*)
· Router A will respond to ARP requests for IP address 172.16.10.120.

11. Refer to the exhibit. What statement is true about the way HSRP is configured?
· Switch DLS1 is the standby router for VLANs 1,10,20.
· Switch DLS2 is the standby router for VLANs 30 and 40.
· Issuing the show standby command on switch DSL1 will reveal that the HSRP state for
VLAN 10 is Standby.
· Issuing the show standby command on switch DSL2 will reveal that the HSRP state for
VLAN 30 is Standby.
· By setting different priorities on different VLANs, a type of load balancing is occurring.
(*)
· If the Ethernet cables between switch DLS2 and switch ALS1 were severed, Payroll Host
would not be able to reach SQL Server.

Module 5 ‐ 5 ‐
12. Refer to the exhibit. HSRP has been configured on the network for redundancy. On the basis
of the configurations that are provided, which router will become an active router when the
current active router R1 goes down?
· Router R2 will become active because the standby preempt command is configured on
this router.
· Router R2 will become active because it has the lowest configured IP address.
· Router R3 will become active because it has the highest priority value that is
configured. (*)
· Router R4 will become active because it has the highest IP address that is configured.

Module 5 ‐ 6 ‐
13. What are two characteristics of Gateway Load Balancing Protocol (GLBP) operation? (Choose
two.)
· GLBP will attempt to balance traffic on a per‐router basis by the use of the round‐robin
algorithm.
· GLBP will attempt to balance traffic on a per‐host basis by the use of the round‐robin
algorithm. (*)
· The active virtual forwarder (AVF) is assigned a virtual MAC address and forwards
packets sent to that MAC address. (*)
· The active virtual gateway (AVG) is the backup for the AVF.
· GLBP members communicate with each other through hello messages sent every 3
seconds to the multicast address 224.0.0.104.
14. Refer to the exhibit. What two pieces of information can be gleaned from the debug standby
command output? (Choose two.)
· The switch has priority 100 configured without the preempt option.
· The switch has priority 100 configured with the preempt option. (*)
· The switch has priority 50 configured with the preempt option.
· The switch has priority 50 configured without the preempt option.
· The switch has become the active HSRP router. (*)
· The switch has become the standby HSRP router.

Module 5 ‐ 7 ‐
15. Refer to the exhibit. Switches DSw1 and DSw2 are configured with the HSRP virtual IP
address 10.10.10.1, and standby priority is set to 100. Assume both switches are booted at
the same time and HSRP is operating as expected. On the basis of this information, which
three HSRP statements are true? (Choose three.)
· Configuring the standby 32 timers 10 30 command on the Gi0/2 interfaces of each switch
would decrease the failover time.
· If the DSw1 and DSw2 switches have been configured to preempt, then DSw2 will be
the active router. (*)
· If the DSw1 switch is configured with the standby preempt command and DSw2 is not,
then DSw1 will be the active router.
· The HSRP group number in this HSRP configuration is HSRP group number 50. (*)
· The standby track command is useful for tracking interfaces that are not configured for
HSRP. (*)
· When Host A sends an ARP request for 10.10.10.1, the Virtual Router replies with the
MAC address of the active router.
