First-Hop Redundancy Protocols: HSRP, VRRP, and GLBP
HSRP, VRRP and GLBP Questions & Answers
1- A company uses GLBP to provide for router redundancy in the network. Which describes the default load balancing scheme used by the Gateway Load Balancing Protocol (GLBP)?
e. Per host basis using a round-robin scheme
2- HSRP has been configured between two Company devices. Which of the following describe reasons for deploying HSRP? (Select all that apply)
a. HSRP provides redundancy and fault tolerance
b. HSRP allows one router to automatically assume the function of the second router if the second router fails
d. HSRP provides redundancy and load balancing
3- In the hardware address 0000.0c07.ac0av, what does 07.ac represent?
e. HSRP well-known virtual MAC address
4- Routers R1 and R2 use HSRP so that one router will back up the other should there be a failure. Which two statements are true about the Hot Standby Router Protocol (HSRP)? (Select two)
b. Routers configured for HSRP can belong to multiple groups and multiple VLANs.
c. Load sharing with HSRP is achieved by creating HSRP groups on the HSRP routers.
5- You need to decide on the best router redundancy protocol to use in the Company network. Which two statements are true about HSRP, VRRP, and GLBP? (Select two)
c. GLBP allows for router load balancing of traffic from a network segment without the different host IP configurations required to achieve the same results with HSRP.
d. Unlike HSRP and VRRP, GLBP allows automatic selection and simultaneous use of multiple available gateways.
6- You need to implement a high availability design in the Company routed network. Which protocol allows for the automatic selection and simultaneous use of multiple available gateways as well as automatic failover between those gateways?
b. GLBP
7- R1 and R2 exchange HSRP between each other in the Company network. In which three HSRP states do routers send hello messages? (Select three)
b. Speak
c. Standby
e. Active
8- Which one of the statements below correctly describes the Virtual Router Redundancy Protocol (VRRP), which is being used in the Company network to provide redundancy?
b. A VRRP group has one master and one or more backup virtual routers.
9- Which of the following protocols enables a group of routers to form a single virtual router, and then use the real IP address of a router as the gateway address, as defined in RFC 2338?
d. VRRP
10- You work as a network technician at Company.com. Your boss is interested in GLBP. In particular, he wants to know the multicast address that this protocol uses. What should you tell him?
c. 224.0.0.102
11- Which first-hop redundancy solution listed would supply Company clients with MAC-address 0000.0C07.AC0A for group 10 in response to an ARP request for a default gateway?
d. HSRP
12- Regarding high availability, with the MAC address 0000.0c07.ac03, what does the “03” represent?
f. The HSRP group number
13- On a 3550 switch, which three types of interfaces can be used to configure HSRP?
b. SVI interface
c. Routed port
e. EtherChannel port channel
15- Which router redundancy protocol cannot be configured for interface tracking?
d. VRRP
16- What is a best practice when implementing failover strategies at the access and distribution layers?
18- Which statement best describes first-hop redundancy protocol status, given the command output in the exhibit?
c. HSRP is configured for group 11.
19- What is the main purpose of implementing Cisco NSF?
b. To continue forwarding IP packets following an RP switchover
20- Refer to the exhibit. Assume that Switch_ A is active for the standby group and the standby device has only the default HSRP configuration. What conclusion is valid?
Switch_A(config-if)# ip address 10.10.10.1 255.255.255.0
Switch_A(config-if)# standby 1 priority 200
Switch_A(config-if)# standby 1 preempt
Switch_A(config-if)# standby 1 track interface fa 1/1
Switch_A(config-if)# standby 1 ip 10.10.10.10
c. If port Fa1/1 on Switch_A goes down, the priority value for the switch would be 190.
