CCNA v7.0 121-140

121. A network administrator is configuring a WLAN. Why would the administrator use a WLAN controller?

• to centralize management of multiple WLANs

• to provide privacy and integrity to wireless traffic by using encryption

• to facilitate group configuration and management of multiple WLANs through a WLC

• to provide prioritized service for time-sensitive applications

122. A new Layer 3 switch is connected to a router and is being configured for interVLAN routing. What are three of the five steps required for the configuration? (Choose three.)

CASE 1

• entering “no switchport” on the port connected to the router

• assigning ports to VLANs

• enabling IP routing

• installing a static route

• assigning the ports to the native VLAN

122. A new Layer 3 switch is connected to a router and is being configured for interVLAN routing. What are three of the five steps required for the configuration? (Choose three.)

CASE 2

• assigning ports to VLANs

• creating SVI interfaces

• creating VLANs

• establishin adjacencies

• installing a static route

122. A new Layer 3 switch is connected to a router and is being configured for interVLAN routing. What are three of the five steps required for the configuration? (Choose three.)

CASE 3

• assigning ports to VLANs

• assigning the ports to the native VLAN

• enabling IP routing

• entering “no switchport” on the port connected to the router

• deleting the default VLAN

122. A new Layer 3 switch is connected to a router and is being configured for interVLAN routing. What are three of the five steps required for the configuration? (Choose three.)

CASE 4

• installing a static route

• enabling IP routing

• assigning ports to VLANs

• creating SVI interfaces

• assigning the ports to the native VLAN

122. A new Layer 3 switch is connected to a router and is being configured for interVLAN routing. What are three of the five steps required for the configuration? (Choose three.)

CASE 5

• assigning ports to VLANs

• assigning the ports to the native VLAN

• enabling IP routing

• creating SVI interfaces

• implementing a routing protocol

123. Which three statements accurately describe duplex and speed settings on Cisco 2960 switches? (Choose three.)

• An autonegotiation failure can result in connectivity issues.

• When the speed is set to 1000 Mb/s, the switch ports will operate in full-duplex mode.

• The duplex and speed settings of each switch port can be manually configured.

• Enabling autonegotiation on a hub will prevent mismatched port speeds when connecting the hub to the switch.

• By default, the speed is set to 100 Mb/s and the duplex mode is set to autonegotiation.

124. Refer to the exhibit. A network administrator configures R1 for inter-VLAN routing between VLAN 10 and VLAN 20. However, the devices in VLAN 10 and VLAN 20 cannot communicate. Based on the configuration in the exhibit, what is a possible cause for the problem?

• A. The port Gi0/0 should be configured as trunk port.

• B. The encapsulation is misconfigured on a subinterface.

• C. A no shutdown command should be added in each subinterface configuration.

• D. The command interface gigabitEthernet 0/0.1 is wrong.

125. A network administrator uses the spanning-tree portfast bpduguard default global configuration command to enable BPDU guard on a switch. However, BPDU guard is not activated on all access ports. What is the cause of the issue?

• BPDU guard needs to be activated in the interface configuration command mode.

• Access ports configured with root guard cannot be configured with BPDU guard.

• Access ports belong to different VLANs.

• PortFast is not configured on all access ports.

126. Which two types of spanning tree protocols can cause suboptimal traffic flows because they assume only one spanning-tree instance for the entire bridged network? (Choose two.)

• MSTP

• RSTP

• Rapid PVST+

• PVST+

• STP
