Perform and verify initial switch configuration tasks including remote access management (10 questions)

QUESTION NO: 1

The following output was displayed on a TestKing device:

While troubleshooting the installation of a new TestKing LAN device, the command output shown above was issued. What is the meaning of the output "MTU 1500 bytes" shown above?

A. The maximum number of bytes that can transverse this interface per second is 1500 B. The maximum segment size that can transverse this interface is 1500 bytes

C. The maximum packet size that can transverse this interface is 1500 bytes D. The maximum frame size that can transverse this interface is 1500 bytes

Answer: C

QUESTION NO: 2

A TestKing Switch is connected as shown below:

Which IOS commands should you enter if you wanted to link the router TestKing1 with switch port 1? (Select three answer choices)

A. Switch(config)# interface fastethernet 0/1 B. Switch(config-if)# switchport mode access

C. Switch(config-if)# switchport mode trunk D. Switch(config-if)# switchport access vlan 1

E. Switch(config-if)# switchport trunk encapsulation isl F. Switch(config-if)# switchport trunk encapsulation dot1q

Answer: A, C, F Explanation:

Before you can begin, you have to get into the interface. Answer choice A is the only command in the selection that puts the IOS into interface mode. Once in the interface you have to set it to trunk mode, so choice C is correct. The switch port needs encapsulation.

Answer choice E give you the choice of ISL and choice F gives you dot1q. Since the diagram suggests that the router is using 802.1Q, you must also use dot1q.

Incorrect Answers:

B, D: We wish to set up a trunk over this connection, not set up a single VLAN.

E. Both ends of the trunk must use the same trunk encapsulation type. Since the diagram shows that the router is set to 802.1Q, the switch must be set up similarly.

QUESTION NO: 3

As a TestKing trainee you are required to set the default gateway on a Cisco switch to the IP address of 192.168.1.115. Which IOS command should you use?

A. TestKSwitch(config)# ip route-default 192.168.1.115 B. TestKSwitch(config)# ip default-gateway 192.168.1.115 C. TestKSwitch(config)# ip route 192.168.1.115 0.0.0.0 D. TestKSwitch(config)# ip default-network 192.168.1.115 E. None of the above

Answer: B Explanation:

Use the "ip default-gateway" command to enter the IP address of the next-hop router interface that is directly connected to the switch where a default gateway is being configured. The default gateway receives IP packets with unresolved destination IP addresses from the switch.

Once the default gateway is configured, the switch has connectivity to the remote networks with which a host needs to communicate.

QUESTION NO: 4

You need to perform some initial configuration tasks on a new TestKing switch.

What is the purpose of assigning an IP address to a switch?

A. To provide local hosts with a default gateway address B. To allow remote management of the switch.

C. To allow the switch to respond to ARP requests between two hosts D. To ensure that hosts on the same LAN can communicate with each other.

E. None of the above

Answer: B Explanation:

Switch is a layer 2 device and doesn't use network layer for packet forwarding. The IP address may be used only for administrative purposes such as Telnet access or for network management purposes.

QUESTION NO: 5

You need to perform some initial configuration tasks on a new TestKing switch.

What are the possible trunking modes for this switch port? (Choose three) A. Transparent

Here, the trunk link is identified by its physical location as the switch module number and port number. The trunking mode can be set to any of the following:

port at the other end of the trunk should be similarly configured because negotiation is not allowed. The encapsulation or identification mode should also be manually configured.

to convert the link to non-trunking mode.

mode. If the far end switch port is configured to on, desirable, or auto mode, trunking will be successfully negotiated.

switch

port is configured to on or desirable, trunking will be negotiated. By default, all Fast Ethernet and Gigabit Ethernet links that are capable of negotiating using DTP are

configured to this mode. Because of the passive negotiation behavior, the link will never become a trunk, if both ends of the link are left to the auto default.

generated for negotiation. The far end switch port must be manually configured for trunking mode.

QUESTION NO: 6

Please study the exhibit carefully. A TestKing technician has installed SwitchB and needs to configure it for remote access from the management workstation connected to SwitchA. Which set of commands is required to accomplish this task?

Exhibit:

A. SwitchB(config)# interface FastEthernet 0/1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

B. SwitchB(config)# ip default-network 192.168.8.254 SwitchB(config)# interface vlan 1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

C. SwitchB(config)# ip route 192.168.8.254 255.255.255.0 SwitchB(config)# interface FastEthernet 0/1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

D. SwitchB(config)# ip default-gateway 192.168.8.254 SwitchB(config)# interface vlan 1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)# no shutdown

E. SwitchB(config)# interface vlan 1

SwitchB(config-if)# ip address 192.168.8.252 255.255.255.0

SwitchB(config-if)# ip default-gateway 192.168.8.254 255.255.255.0 SwitchB(config-if)# no shutdown

F. None of the above

Answer: D Explanation:

IP default-gateway address is a global command that sets the default gateway so that the management interface can be reached from a remote network. This is the correct

command used on Cisco switches. In this example, the interface also needs to be enable using the "no shut" command.

Incorrect Answers:

A: The default gateway of the switch needs to be specified.

B: The correct command for a switch is "ip default-gateway" not "ip default-network"

C: This static route is not valid, and does not correctly specify the default route.

E: "IP default-gateway" is a global command, not an interface command.

QUESTION NO: 7

An administrator would like to configure a switch over a virtual terminal connection from locations outside of the local LAN. Which of the following are required in order for the switch to be configured from a remote location? (Choose two)

A. The switch must be reachable through a port connected to its management VLAN.

B. The switch console port must be connected to the Ethernet LAN.

C. The switch must be fully configured as an SNMP agent.

D. The switch must be configured with an IP address, subnet mask, and default gateway.

E. The switch management VLAN must be created and have a membership of at least one switch port.

F. The switch must be connected to a router over a VLAN trunk.

Answer: A, D Explanation:

In order the telnet to any Cisco device, the device must be reachable from the remote location. For a Cisco switch to be reachable from remote locations, it must have an IP address, subnet mask, and default gateway assigned.

Communication with the switch management interfaces is through the switch IP address.

The IP address is associated with the management VLAN, which by default is VLAN 1

QUESTION NO: 8

A TestKing LAN is shown in the diagram below:

In this network, Host TestKing1 is consoled into Switch TestKingA. Telnet connections and pings run from the command prompt on Switch TestKingA fail.

Which of the following could cause this problem? Select all that apply.

A. Switch TestKingA is not directly connected to router TestKingC.

B. Switch TestKingA does not have a default gateway assigned.

C. Switch TestKingA does not have a CDP entry for Switch TestKing B or Router TestKingC.

D. Switch TestKingA does not have an IP address.

E. Port 1 on Switch TestKingA should be an access port rather than a trunk port.

Answer: B, D

For ping and Telnet the switch should be configured with the IP address and the default gateway. IP is used for administrative purposes, and is needed so the end device will know which IP address to direct the ICMP and telnet reply traffic to.

Incorrect Answers:

A. This is not required, since switch LANs can span multiple VLANs and switches and hubs can be connected directly together.

C. CDP is not required in order for ping and telnet traffic to work.

E. The port type in this case will not cause any kind of connectivity problems, since Trunk ports pass information from all VLANs by default.

QUESTION NO: 9

The TestKing network administrator cannot connect to SwitchTK1 over a Telnet session, although the hosts attached to SwitchTK1 can ping the interface Fa0/0 of the router. Given the information shown below and assuming that the router and Switch2 are configured properly, which of the following commands should be issued on SwitchTK1 to correct this problem?

Exhibit:

A. SwitchTK1(config)# ip default-gateway 192.168.24.1 B. SwitchTK1(config)# interface fa0/1

SwitchTK1(config-if)# ip address 192.168.24.3 255.255.255.0 C. SwitchTK1(config)# line con0

SwitchTK1(config-line)# password cisco SwitchTK1(config-line)#login

D. SwitchTK1(config)# interface fa0/1 SwitchTK1(config-if)# duplex full SwitchTK1(config-if)# speed 100 E. SwitchTK1(config)# interface fa0/1

SwitchTK1(config-if)# switchport mode trunk F. None of the above

Answer: A Explanation:

To route traffic to other vlans, we need to enter the IP address of the next-hop router interface that is directly connected to the switch where a default gateway is being configured. The default gateway receives IP packets with unresolved destination IP addresses from the switch.

Once the default gateway is configured, the switch will have connectivity to the remote networks with which a host needs to communicate.
