CCNA 2 Final Exam Review

A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config)#interface VLAN88 command?

• It enters configuration mode for a switch virtual interface

• It applies an IPv4 address the virtual interface

• It applies an IPv6 address to the virtual interface

• It permits an IPv6 address to be configured on a switch physical interface

• It updates the MAC address table for the associated port

Which problem is evident if the show ip interface command shows that the interface is down and the line protocol is down?

• An encapsulation mismatch has occurred

• A cable has not been attached to the port

• The no shutdown command has not been issued on the interface

• There is an IP address conflict with the configured address on the interface

In what situation would a Layer 2 switch have an IP address configured?

• when the Layer 2 switch needs to forward user traffic to another device

• when the Layer 2 switch is the default gateway of user traffic

• when the Layer 2 swtich nees to be remotely managed

• when the Layer 2 swtich is using a routed port

Which type of traffic is designed for a native VLAN?

• user-generated

• tagged

• untagged

• management

What type of VLAN is configured specifically for network traffic such as SSH, Telnet, HTTPS, HTTP, and SNMP?

• management VLAN

• trunk VLAN

• security VLAN

• voice VLAN

Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?

• The native VLAN should be VLAN 60.

• The native VLAN is being pruned from the link.

• The trunk has been configured with the switchport nonegotiate command.

• The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.

Refer to the exhibit. DLS1 is connected to another switch, DLS2, via a trunk link. A host that is connected to DLS1 is not able to communicate to a host that is connected to DLS2, even though they are both in VLAN 99. Which command should be added to Fa0/1 on DLS1 to correct the problem?

• switchport nonegotiate

• switchport mode dynamic auto

• switchport trunk native vlan 66

• switchport trunk allowed vlan add 99

A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?

• Add more switches so that fewer devices are on a particular switch.

• Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch.

• Segment the LAN into smaller LANs and route between them.

• Replace at least half of the switches with hubs to reduce the size of the broadcast domain.

What are two switch characteristics that could help alleviate network congestion? (Choose two.)

• fast internal switching

• frame check sequence (FCS) check

• large frame buffers

• low port density

• store-and-forward switching

Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?

• SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.

• SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.

• SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.

• SW1 drops the frame because it does not know the destination MAC address.
