CCNA 3 Chapter 1 -2014

1. Which layer of the hierarchical network design model is refered to as the high-speed backbone of the internetwork, where high availability and redundancy are critical?

core layer

2. Which two characteristics are associated with enterprise level switches? (Choose two.)

high forwarding rate

support link aggregation

3. Which feature supports higher throughput in switched networks by combining multiple switch ports?

link aggregation

4. Which hierarchical design model layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs (VLANs)?

distribution

CCNA 3 Chapter 2 -2014

1. If a network administrator enters these commands on a switch, what will be the result?

Switch1(config-line)# line console 0

Switch1(config-line)# password cisco

Switch1(config-line)# login

to configure the privilege exec password that will be used for remote access

2. Which command line interface (CLI) mode allows users to configure switch parameters, such as the hostname and password?

global configuration mode

3. What happens when the transport input ssh command is entered on the switch vty lines?

Communication between the switch and remote users is encrypted.

4. A network administrator uses the CLI to enter a command that requires several parameters. The switch responds with "% Incomplete command". The administrator cannot remember the missing parameters. What can the administrator do to get the parameter information?

append a space and then ? to the last parameter

CCNA 3 Chapter 3 -2014

1. Refer to the exhibit. The network administrator has just added VLAN 50 to Switch1 and Switch2 and assigned hosts on the IP addresses of the VLAN in the 10.1.50.0/24 subnet range. Computer A can communicate with computer B, but not with computer C or computer D. What is the most likely cause of this problem?

VLAN 50 is not allowed to entering the trunk between Switch1 and Switch2.

2. Refer to the exhibit. The exhibited configurations do not allow the switches to form a trunk. What is the most likely cause of this problem?

The trunk cannot be negotiated with both ends set to auto.

3. Refer to the exhibit. Which two conclusions can be drawn regarding the switch that produced the output shown? (Choose two.)

The command switchport access vlan 20 was entered in interface configuration mode for Fast Ethernet interface 0/1.

Devices attached to ports fa0/5 through fa0/8 cannot communicate with devices attached to ports fa0/9 through fa0/12 without the use of a Layer 3 device.

4. What statements describe how hosts on VLANs communicate?

Hosts on different VLANs communicate through routers.

CCNA 3 Chapter 4 -2014

1. Which statement is true when VTP is configured on a switched network that incorporates VLANs?

VTP dynamically communicates VLAN changes to all switches in the same VTP domain.

2. Refer to the exhibit. What information can be learned from the output provided?

It verifies VTP advertisements are being exchanged.

3. Refer to the exhibit. Which two facts can be confirmed by this output? (Choose two.)

If this switch is added to an established network, the other VTP-enabled switches in the same VTP domain will consider their own VLAN information to be more recent than the VLAN information advertised by this switch.

This switch is configured to advertise its VLAN configuration to other VTP-enabled switches in the same VTP domain.

4. A network administrator is replacing a failed switch with a switch that was previously on the network. What precautionary step should the administrator take on the replacement switch to avoid incorrect VLAN information from propagating through the network?

Change the VTP domain name.
