CCNA 2 (Version 7.00) SRWE Practice Final Exam Answers

A network administrator is using the router-on-a-stick method to configure inter-VLAN routing. Switch port Gi1/1 is used to connect to the router. Which command should be entered to prepare this port for the task?

• Switch(config)# interface gigabitethernet 1/1
  Switch(config-if)# spanning-tree vlan 1

• Switch(config)# interface gigabitethernet 1/1
  Switch(config-if)# spanning-tree portfast

• Switch(config)# interface gigabitethernet 1/1
  Switch(config-if)# switchport mode trunk

• Switch(config)# interface gigabitethernet 1/1
  Switch(config-if)# switchport access vlan 1

Refer to the exhibit. The configuration shows commands entered by a network administrator for inter-VLAN routing. However, host H1 cannot communicate with H2. Which part of the inter-VLAN configuration causes the problem?

• • trunking

• • port mode on the two switch FastEthernet ports

• • VLAN configuration

• • router port configuration

Refer to the exhibit. Inter-VLAN communication between VLAN 10, VLAN 20, and VLAN 30 is not successful. What is the problem?

• The router interface is not configured with subinterfaces for each VLAN.

• The switch ports are not assigned to the correct VLANs.

• The trunk link between the switch and router is not configured.

• The VLANs are not created on the switch.

Which switch interface must be configured as a trunk interface to forward all VLANs to the router?

• FastEthernet0/1

• FastEthernet0/2

• FastEthernet0/3

• FastEthernet0/4

To forward all VLANs to the router, the switch interface Fa0/1 must be configured as a trunk interface with the ________ command.

• switchport mode trunk

• switchport access vlan 1

• interface vlan 1

• ip routing

Explain why the switch interface FastEthernet0/1 should be configured as a trunk interface instead of an access interface to forward all VLANs to the router.

• Because a trunk interface can carry traffic for multiple VLANs, allowing all VLANs to be forwarded to the router.

• Because an access interface can forward all VLANs to the router by default.

• Because a trunk interface restricts traffic to only one VLAN, improving security.

• Because an access interface is required for inter-VLAN routing.

An employee connects wirelessly to the company network using a cell phone. The employee then configures the cell phone to act as a wireless access point that will allow new employees to connect to the company network. Which type of security threat best describes this situation?

• rogue access point

• spoofing

What address and prefix length is used when configuring an IPv6 default static route?
