Question 31

The standard Ethernet frame length should not be less than 64 bytes.
Which of the following factors cause this limitation? (Multiple choice)

A.MAC address

B.Maximum transmission distance

C.Working Mechanism of Conflict Detection

D.Minimum transmission distance

Question 32

Which of the following description about MPLS (Multiprotocol Label Switching) is wrong?

A.MPLS packet forwarding is based on labels.

B.In the field of packet transmission, the main application of MPLS technology is to build tunnels to carry various types of services (such as: TDM, ATM, Ethernet) transmitted by PWE3, and realize end-to-end transmission of services in the packet network.

C.MPLS adopts a dual-plane structure, which is divided into a control plane and a forwarding plane. The control plane is connection-oriented, and the forwarding plane is connectionless-oriented.

D.MPLS is not a service or application, but a standardized routing and switching technology platform that can support various high-level protocols and services

Question 33

The dual-fiber bidirectional wavelength division multiplexing system uses two optical fibers to realize bidirectional optical signal transmission, and the same wavelength cannot be used for sending and receiving optical signals in two directions.

A.False

B.True

Question 34

The EMR8 board is a fixed multiplexer/demultiplexer board, which can support up to 8 specific discontinuous wavelengths.

A.False

B.True

Question 35

When the input optical power of the amplifier of the OAU at the receiving end is lower than the nominal optical power, which of the following operations are wrong?

A.When the input optical power cannot be increased by adjusting the adjustable attenuator, the adjustable attenuation at the input end of the amplifier should be suppressed

B.Adjust the adjustable optical attenuation before the receiver amplifier to increase the input optical power of the amplifier

C.Set the OAU gain to make its output reach the nominal value

D.Increase the sending optical power of the sending end
