Answer: C

Explanation:

switch ports by examining the source address of frames that are received on that port.

the same switch or a different switch.

all ports except the source to find out the destination host.

In the output there is no MAC address of the given host so the switch will flood to all ports except the source port, which is port fa 0/3.

QUESTION NO: 11

Refer to the topology and MAC address table shown in the exhibit:

Host TestKingA sends a data frame to host TestKingD. What will the TestKing1 switch do when it receives the frame from host A?

A.The TestKing1 switch will flood the frame out of all ports except for port Fa0/3.

B.The TestKing1 switch will discard the frame and send an error message back to host TestKingA.

C.The TestKing1 switch will add the destination address of the frame to the MAC address table and forward the frame to host D.

D.The TestKing1 switch will add the source address and port to the MAC address table and forward the frame to host TestKingD.

E.None of the above

Answer: D Explanation:

When switch receives the data frame from the host not having the MAC address already in the MAC table, it will add the MAC address to the source port on the MAC address table and sends the data frame. If the switch already has the MAC address in it's table for the destination, as it is in this case, it will forward the frame directly to the destination port. If it was not already in it's MAC table, then they frame would have been flooded out all ports except for the port that it came from.

QUESTION NO: 12

Switch TestKingA receives the frame with the addressing shown in the exhibit.

According to the command output also shown in the exhibit, how will Switch TestKingA handle this frame?

A.It will flood the frame out all ports except Fa0/3.

B.It will forward the frame out port Fa0/3 only.

C.It will flood the frame out all ports.

D.It will forward the frame out port Fa0/6 only.

E.It will drop the frame.

F.None of the above

Answer: D Explanation:

When frame receives the frame, it checks the source address on MAC table if MAC address found in MAC table it tries to forward if not in MAC table adds the Address on MAC table. After checking the source address, it checks the destination address on MAC table, if MAC address found on MAC table it forwards to proper ports otherwise floods on all ports except the source port. In this case, the MAC address shown is already in the table so it will be forwarded directly.

QUESTION NO: 13

Please study the exhibit shown below carefully.

Why does the switch have two MAC addresses assigned to the FastEthernet 0/1 port in the switch address table?

A.Either Host3 or Host4 has just had the NIC replaced.

B.Data from Host3 and Host4 has been received by switch port FastEthernet 0/1.

C.Host3 and Host4 are on two different VLANs.

D.Data from two of the devices connected to the switch has been sent to Host3.

E.None of the above

Answer: B Explanation:

Switches learn the MAC addresses of PCs or workstations that are connected to their switch ports by examining the source address of frames that are received on that port. When more than one device is attached to a switch port, such as via the use of a hub as shown in this example, the switch will retain the MAC address of each of the known devices on that port.

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?

- 128 -

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

Leading the way in IT testing and certification tools, www.testking.com

- 129 -

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.
