A. The L2VE interface can be directly selected as a member port of MC-LAG

B. The heartbeat is carried by unidirectional LSP and configured with 1:1 protection

C. Configurable to load burden mode

D. The higher the active/standby priority value, the lower the priority

正確答案: D

問題7

When configuring electrical layer crossing, what are the rules for time slot configuration?

A. For the convenience of management and maintenance, it is recommended to set the time slot cutting mode to automatic mode

B. After changing the service type, there is no need to reset the service time slot

C. For each board, the same time slot in the same direction cannot be used by multiple services at the same time

D. For the same service, the time slots occupied by the receiving turbulence and the transmitting turbulence in one direction must be the same

正確答案: A,C,D

問題8

Which of the following statements about 100G coherent PDM-QPSK modulation is incorrect?

A. The essence of QPSK modulation is to reduce the baud rate of the optical signal by half without reducing the line rate by selecting 4 possible values in the phase of the optical field.

B. PDC-QPSK supports DCMfree and DCM system applications, and supports smooth upgrade from existing 10G/40G network to 100G system.

C. PDM polarization multiplexing technology is adopted, which has better nonlinear tolerance than
40GePDM-BPSK.

D. PDM-QPSK technology is the main modulation code technology for 100G transmission, which can reduce the line rate of 112Gb/s to the baud rate of 28Gbaud/s, greatly reducing the loan requirements for (optical) electrical devices.

正確答案: C

問題9
