Huawei Huawei Certifications H13-341 Questions & Answers

• Question 11:

  FXS and FXO are the names of the ports used by analog telephone lines. FXO ports and FXS ports are always used in pairs.

  A. True

  B. False

  Correct Answer: B

• Question 12:

  Which of the following statements about AU pointers are correct?

  A. The root cause of the AU pointer justification is that the clocks of the upstream and downstream stations are not synchronized.

  B. AU_PTR indicates the position of the J0 byte.

  C. If the receive end detects that the H1H2 bytes are "1", the local end generates the AU-AIS alarm.

  D. The value of the AU-PTR pointer is placed in the last 10 bits of the H1 and H2 bytes. Therefore, the valid value of the AU-PTR pointer is 0~1023.

  Correct Answer: C

• Question 13:

  Which of the following signals can be used as input or output signals of an external clock interface?

  A. 2.048 MHz

  B. 2.048 Mbit/s

  C. 155 Mbit/s

  D. 34 Mbit/s

  Correct Answer: A

• Question 14:

  The overhead ratio is a factor that affects the error correction capability of the FEC technology. Generally, when the same FEC encoding/decoding is used, the higher the overhead ratio is, the larger the net coding gain is.

  A. True

  B. False

  Correct Answer: B

• Question 15:

  Which of the following is not a PW APS switching condition?

  A. A warm reset is performed on the board.

  B. The board software is faulty.

  C. MPLS_PW_SF

  D. A cold reset is performed on the board.

  Correct Answer: A

  A. True

  B. False

  Correct Answer: A

• Question 20:

  Which of the following statements about MPLS is wrong?

  A. MPLS has two planes: control plane and forwarding plane. The control plane is connection-oriented, the forwarding plane is connectionless.

  B. MPLS is not a service or application. It is a standard routing and switching platform that supports various upper-layer protocols and services.

  C. In the packet transport field, the MPLS technology is mainly used to construct tunnels to carry various types of services (for example, TDM, ATM, and Ethernet) transmitted by PWE3 to implement end-toend transmission of services on packet networks.

  D. MPLS packet forwarding is based on labels.

  Correct Answer: A
