Which of the following statements about ROADM are correct?

A. ROADM technology uses the NMS software to deliver configurations to implement the wavelength adding/dropping and pass-through status.

B. NG WDM equipment supports ROADM with fixed spectrum and Flexible ROADM with flexible spectrum.

C. ROADM can adjust the optical power of the pass-through wavelength and the added wavelength.

D. OandM personnel need to provide onsite support for wavelength adjustment at ROADM sites.

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.

A. Loopback

B. Service Signal Flow Analysis

C. RMON

D. Replacement

In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites. After receiving the OTUk_TIM alarm on the client side, the OTU board at station A sends the OTUk_BDI alarm to the upstream. When the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. The WDM side of the OTU board at station B reports the ODUk_PM_AIS alarm, and the ODUk_PM_AIS alarm is transmitted downstream. The client equipment reports this alarm. After the WDM side of the OTU board at station B receives the OTUk_TIM alarm and the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. After the client side of station B processes the SF event, the client equipment reports the ODUk_PM_AIS alarm.

A. True

B. False

If tunnel APS is configured for the tunnel to which the PW belongs, PW APS cannot be configured for the PW.

A. True

B. False

MPLS APS is a network protection mechanism. It implements service switching by using the MPLS OAM detection function.

A. True

B. False

Which of the following is the client-side logical port of a board in standard mode?
