Question No: 21 – (Topic 1)

A router has two Fast Ethernet interfaces and needs to connect to four VLANs in the local network. How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance?

  1. Use a hub to connect the four VLANS with a Fast Ethernet interface on the router.

  2. Add a second router to handle the VLAN traffic.

  3. Add two more Fast Ethernet interfaces.

  4. Implement a router-on-a-stick configuration.

Answer: D

What will Router1 do when it receives the data frame shown? (Choose three.)

  1. Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.

  2. Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1.

  3. Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.

  4. Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1.

  5. Router1 will forward the data packet out interface FastEthernet0/1.

  6. Router1 will forward the data packet out interface FastEthernet0/2.

Question No: 25 – (Topic 1)

Which of the following correctly describe steps in the OSI data encapsulation process? (Choose two.)

  1. The transport layer divides a data stream into segments and may add reliability and flow control information.

  2. The data link layer adds physical source and destination addresses and an FCS to the segment.

  3. Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information.

  4. Packets are created when the network layer adds Layer 3 addresses and control information to a segment.

  5. The presentation layer translates bits into voltages for transmission across the physical link.

Answer: A,D

  1. What causes this behavior?

    1. trunk mode mismatches

    2. allowing only VLAN 2 on the destination

    3. native VLAN mismatches

Answer: C

Question No: 29 – (Topic 2)

Which three of these statements regarding 802.1Q trunking are correct? (Choose three.)

  1. 802.1Q native VLAN frames are untagged by default.

  2. 802.1Q trunking ports can also be secure ports.

  3. 802.1Q trunks can use 10 Mb/s Ethernet interfaces.

  4. 802.1Q trunks require full-duplex, point-to-point connectivity.

  5. 802.1Q trunks should have native VLANs that are the same at both ends.

Answer: A,C,E

Question No: 30 – (Topic 2)

Refer to the exhibit.

image

All switch ports are assigned to the correct VLANs, but none of the hosts connected to SwitchA can communicate with hosts in the same VLAN connected to SwitchB. Based on the output shown, what is the most likely problem?

  1. The access link needs to be configured in multiple VLANs.

  2. The link between the switches is configured in the wrong VLAN.

  3. The link between the switches needs to be configured as a trunk.

  4. VTP is not configured to carry VLAN information between the switches.

  5. Switch IP addresses must be configured in order for traffic to be forwarded between the

switches.
