Q3. Which two prerequisites for HSRP to become active on an interface are true? (Choose two.)

A. Cisco Express Forwarding must be disabled globally.

B. The VIP must be in the same subnet as the primary IP address.

C. A Virtual-MAC address must be configured on the interface.

Answer: B,D

Q4. CORRECT TEXTThe headquarter office for a cement manufacturer is installing a temporary Catalyst 3550 in an IDF to connect 24 additional users.

To prevent network corruption, it is important to have the correct configuration prior to connecting to the

production network.

It will be necessary to ensure that the switch does not participate in VTP but forwards VTP advertisements that are received on trunk ports.

Because of errors that have been experienced on office computers, all non-trunking interfaces should transition immediately to the forwarding state of Spanning tree. Also configure the user ports (all FastEthernet ports) so that the ports are permanently non-trunking.

Requirement:

You will configure FastEthernet ports 0/12 through 0/24 for users who belong to VLAN 20. Also all VLAN and VTP configurations are to be completed in global configuration mode as VLAN database mode is being

deprecated by Cisco. You are required to accomplish the following tasks:

1. Ensure the switch does not participate in VTP but forwards VTP advertisements received on trunk ports.

2. Ensure all non-trunking interfaces (Fa0/1 to Fa0/24) transition immediately to the forwarding state of

Spanning-Tree.

3. Ensure all FastEthernet interfaces are in a permanent non-trunking mode.

4. Place FastEthernet interfaces 0/12 through 0/24 in VLAN 20.

Answer:

Please Refer to Explanation below for details:

Explanation/Reference:

Console into the Switch Switch>enable Switch#configure terminal

Switch(config)#interface range fa0/1 u2013 24

Switch(config-if-range)#switchport mode access <<Make all FastEthernet interfaces into access mode.

Switch(config-if-range)#spanning-tree portfast <<Enables the PortFast on interface. Next, we need to assign FastEthernet ports 0/12 through 0/24 to VLAN 20. By default, all ports on the switch

are in VLAN 1. To change the VLAN associated with a port, you need to go to each interface (or a range of

interfaces) and tell it which VLAN to be a part of. Switch(config-if-range)#interface range fa0/12 u2013 24

Switch(config-if-range)#switchport access vlan 20 <<Make these ports members of vlan 20 Switch(config-if-range)#exit

Next we need to make this switch in transparent mode. In this mode, switch doesnu2021t participate in the VTP

domain, but it still forwards VTP advertisements through any configured trunk links. Switch(config)#vtp mode transparent

Switch(config)#exit

Switch#copy running-config startup-config

Q5. Which statements about RSPAN are true? (Choose two.)

A. It supports MAC address learning.

B. RSPAN VLANs can carry RSPAN traffic only.

C. Only one RSPAN VLAN can be configured per device.

D. RSPAN VLANs are exempt from VTP pruning.

E. MAC address learning is not supported.

F. RSPAN uses are GRE tunnel to transmit captured traffic.

Answer: B,E

Q6. Which two statements about SDM templates are true?

A. They are used to allocate system resources

B. Changing the SDM template will not disturb switch operation.

C. You can verify the SDM template that is in use with the show sdm prefer command

Answer: A,C

Q7. Which virtual MAC address does HSRP group 37 use with default configuration?

A. C0.00:00:25:00:00

B. 00:00:0c:07:ac:25

C. C0:00:00:37:00:00

D. 00:00:00c:07:ac:37

Answer: D

Q8. HSRP was implemented and configured on two switches while scheduled network maintenance was

performed.

After the two switches have finished rebooting, you notice via show commands that Switch2 is the HSRP active router. Which two items are most likely the cause of Switch1 not becoming the active router? (Choose two)

A. booting delays

B. standby group number does not match VLAN number

C. IP addressing is incorrect

D. premption is disabled

E. incorrect standby timers

F. IP redirect is disabled

Answer: A,D

Q9. Which statement about GLBP is true?

A. Unused bandwidth is never utilized.

B. They communicate under TCP port 3222 for both source and destination.

C. They become active if any of the existing forwarding switches fail.

D. They become restricted if any of the existing forwarding switches fail.

Answer: C

Q10. Which two statements about default FHRP behavior are true? (Choose two)

A. A backup GLBP active virtual gateway can become active only if the current active virtual gateway fails.

B. Preemption is enabled by default.

C. Unless specifically Configured, the priority of an HSRP router is 200.

D. A standby HSRP router becomes active if it has a higher priority than the priority of the current active router.

E. A VRRP backup virtual router becomes the master router if its priority is higher than the priority of the current master router.

Answer: A,E
