Question No.323

Which two statements about subnet masks are true? (Choose two.)

  1. If a bit is turned on (1), the corresponding bit in the IP address is used for the host portion.

  2. If a bit is turned off (0), the corresponding bit in the IP address is used for the host portion.

  3. If a bit is turned on (1), the corresponding bit in the IP address is used for the network prefix.

  4. If a bit is turned off (0), the corresponding bit in the IP address is used for the network prefix.

Correct Answer: D

Question No.325

In Ethernet networks, duplex mismatches will lower performance. Which error statistics can be seen if a duplex mismatch is present?

  1. collisions on the full-duplex side; runts on the half-duplex side

  2. collisions on the full-duplex side; collisions on the half-duplex side

  3. collisions on the half-duplex side; framing errors on the full-duplex side

  4. collisions on the half-duplex side; giants on the full-duplex side

Correct Answer: C

Explanation:

On an Ethernet connection, a duplex mismatch is a condition where two connected devices operate in different duplex modes, that is, one operates in half duplex while the other one operates in full duplex.

This results in the full-duplex side receiving an incomplete frame with CRC error or a runt frame. It does not detect any collision since CSMA/CD is disabled on the full-duplex side. As a result, when both devices are attempting to transmit at (nearly) the same time, the packet sent by the fullduplex end will be discarded and lost due to an assumed collision and the packet sent by the half duplex device will be delayed or lost due to a CRC error in the frame.

Question No.326

What is the default firewall filter behavior when a term is matched but no terminating action is specified?

  1. an implicit deny and the filter evaluation terminates

  2. an implicit accept and the filter evaluation terminates

  3. an implicit accept and the filter evaluation continues to the next term

  4. an implicit deny and the filter evaluation continues to the next term

Correct Answer: C

Question No.327

What is correct regarding the configuration shown below?

static route 0.0.0.0/0 qualified-next-hop 172.30.25.1 preference 7 next-hop 172.30.25.5

  1. The next-hop 172.30.25.1 is selected because the address has the lowest value.

  2. The next-hop 172.30.25.1 is selected because it is listed first.

  3. The next-hop 172.30.25.1 is selected because it is the lowest protocol preference.

  4. The next-hop 172.30.25.5 is selected because it is the lowest protocol preference.

    Correct Answer: D

    Explanation:

    The routes with a lower route preference are always used to route traffic. Preference 5 is the default preference for static routes.

    C.

    9

    D.

    12

    Correct Answer: B

    Question No.329

    Which two options are reasons for using traffic classification? (Choose two.)

    1. to use the classification to route traffic

    2. to use the classification to reorder packets from various sources

    3. to use the classification to discard malformed packets

    4. to use the classification to provide the configured service level

Correct Answer: AD

Explanation:

Classification entails using a traffic descriptor to categorize a packet within a specific group to define that packet and make it accessible for QoS handling on the network. Using packet classification, you can partition network traffic into multiple priority levels or classes of service.
