1 How many HSRP (Hot Standby Routing Protocol) groups will need to be configured for each VLAN?

2

3

4

1

2 What three tasks must be performed to successfully configure Hot Standby Routing Protocol (HSRP)?

Define the encapsulation type

Define the standby route

Define the IP address

Enable the standby mode

Enable HSRP

3 In what three states is it possible for an HSRP router to be in? (Select three)

Standby

Established

Idle

Active

Init

Backup

4 Which one of the statements below correctly describes the Virtual Router Redundancy Protocol (VRRP)?

A VRRP group has one active and one or more standby virtual routers

A VRRP group has one master and one redundant virtual router

A VRRP group has one active and one or more standby virtual routers

A VRRP group has one master and one or more backup virtual routers

5 On a 3550 EMI switch, which three types of interfaces can be used to configure HSRP?

Loopback interface

SVI interface

Routed port

Access port

EtherChannel port

BVI interface

6 The RP with the highest Priority (default is 100) is elected as the Active RP and the RP with the second highest Priority is elected

as the Standby RP If both priorities are the same, what is used as the tiebreaker for an RP to become the active RP?

The RP with the lowest IP address

The RP with the highest IP address

The RP with the lowest MAC address

The RP with the highest MAC address

7 Which of the following statements accurately describes the function of Cisco HSRP?

An HSRP group consists of one or more active routers to ensure continual network link availability

An HSRP group consists of exactly two standby routers to ensure continual network link availability

An HSRP route processor can belong to multiple groups but only within the boundaries of a single VLAN

HSRP allows multiple routers to automatically assume the function of the standby router if the current standby router fails

8 What kind of message does an HSRP configured router send out every 3 seconds?

Desire

Snoop

Hello

Send

Resign

9 "Which command will need to be added to Router2 to ensure that it will take over if serial 0/0 on Router1 fails? Router1 running config.: hostname Router1 interface fastethernet 0/0 ip address 192.168.1.1 255.255.255.0 standby 9 ip 192.168.1.11 255.255.255.0 standby 9 priority 110 standby 9 track serial 0/0 Router2 running config.: hostname Router2 interface fastethernet 0/0 ip address 192.168.1.2 255.255.255.0 standby 9 ip 192.168.1.11 255.255.255.0 standby 9 track serial 0/0

standby 9 track fastethernet 0/0

standby 9 track 192.168.1.1

standby 9 priority 130

standby 9 preempt

None of the above

10 What types of RPs will each HSRP group contain? Choose four

Virtual RP

11 Which protocol is an extension of ICMP that allows an IP host to find a new router when a router becomes unavailable(RFC 1256)?

HSRP

SNMP

IRDP

VRRP

None of the above

12 Which statement describes Virtual Router Redundancy Protocol (VRRP)?

A VRRP group has one master and at least one standby virtual router

A VRRP group has one master and one more backup virtual router

A VRRP group has one active and one more standby virtual routers

A VRRP group has one active and one backup virtual router

13 HSRP supports six states in the following order: Initial, Learning, Listening, Speaking, Standby, and Active What happens when

an RP enters the Speaking state?

Listens for an active RP

Learns about the virtual IP address

Propagates broadcast messages so it can participate in the election

Propagates multicast messages so it can participate in the election

14 What three tasks must a network administrator perform to properly configure Hot Standby Routing Protocol (HSRP)? (Select three)

Define the encapsulation type

Define the standby router

Define the standby preempt number

Define the standby IP address

Enable the standby priority

15 You want to allow router to immediately become the active router if its priority is highest than the active router fails What command would you use if you wanted to configure this?

standby preempt

standby preempt enable

standby preempt

hot standby preempt

16 What are the three different Op Codes contained in an HSRP multicast message?

Hello message

Resign message

Coup message

State message

17 On a 3550 EMI switch, which two types of interfaces can be used to configure HSRP?

Loopback interface

SVI interface

Routed port

Access port

BVI interface

18 Which of the following describe reasons for deploying HSRP? (Select three)

HSRP provides redundancy and fault tolerance

HSRP allows one router to automatically assume the function of the second router if the second router starts

HSRP allows one router to automatically assume the function of the second router if the second router fails

HSRP provides redundancy and load balancing

19 Which of the following is a valid HSRP virtual MAC address?

0000.0b07.ac11

0000.0a07.ac10

0000.0c07.ac10

0000.0d07.acz2

per session using a strict priority scheme

per host using a strict priority scheme

per session using a round robin scheme

per host using a round robin scheme

per GLBP group using a round robin scheme

per GLBP group using a strict priority scheme

21 In the hardware address 0000.0c07.ac0av, what does 07.ac represent?
