Which of the following is not an advantage of WDM?

• A.Transparent transmission of data
• B.Various overheads
• C.Flexible, economical, and reliable networking
• D.Ultra-large capacity and ultra-long haul transmission

When the R_LOS, R_LOF, R_OOF, or MUT_LOS alarm is reported on a device, services are interrupted.

• A.TRUE
• B.FALSE

WDM systems generally use DCMs to compensate for chromatic dispersion. Which of the following statements about DCM-based dispersion compensation is false?

• A.If the DCM configuration is false, the receive-end performance will deteriorate.
• B.For a 10G system with a fiber length shorter than 400 km, G.652-specific DCMs can be used to compensate for dispersion in G.655 (Leaf) optical fibers.
• C.If the DCM configuration is incorrect, the system OSNR will deteriorate.
• D.Compared with line transmission optical fibers, DCMs are prone to non-linear effects. Therefore, the incident optical power of the DCMs must be controlled.

Which of the following statements about port priorities in the LAG setting scenario are true?

• A.Port priorities do not apply to the LAGs that do not run LACP, such as manual aggregation groups.
• B.The priority of a port Is higher If the value of "tort Priority" is smaller.
• C.A port of a lower priority carries a service preferentially.
• D.If the primary port is configured to preferentially carry services, the priority of this port must be higher than that of other ports.

OTUk_DEG indicates OTUk signal degradation. Which of the following statements about the bit error detection mode are true? (Choose all that apply.)

• A.When bit errors are detected in burst mode, this alarm is reported after signal degradation occurs.
• B.When bit errors are detected in burst mode, this alarm is reported after signal degradation or bit error threshold crossing occurs.
• C.When bit errors are detected in Poisson mode, this alarm is reported after signal degradation or bit error threshold crossing occurs.
• D.When bit errors are detected in Poisson mode, this alarm is reported after signal degradation occurs.
