SF is a signal failure event and SD is a signal degradation event. Both the SF and SD events are conditions for triggering protection switching, but whether the SD time is used as a trigger switching condition can be set by the user.

• A.FALSE
• B.TRUE

Which of the following is not a function of RSVP-TE?

• A.LSP deletion
• B.LSP rerouting
• C.Establish neighbor relationship
• D.LSP path optimization

Which of the following description of the principle of automatic protection switching of the standard SSM protocol are correct? (Multiple choice)

• A.If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.
• B.According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the homologous source.
• C.The network element broadcasts the clock quality information of the synchronization source to the downstream site through the S1 byte, and notifies the upstream station that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.
• D.The network element broadcasts the clock quality information and the clock source ID of the synchronization source through the downstream station between the S1 bytes, and notifies the upstream station that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.

Which of the following description are wrong about the path method to create a Client path?

• A.If the route to be automatically calculated is different from the planned path, you can set the "constrained node" or "must pass through the node" to perform routing constraints.
• B.Create a client service path by using the path method. After the creation, the optical layer OCh path is automatically generated to reduce the secondary teaching of the path creation.
• C.The creation or search of a new path must be possible if its upper service layer path already exists.
• D.Select the "Activate" checkbox. After the path is successfully created, it will be delivered to the NE layer. Otherwise, the path configuration text will only be saved on the network management side.

Which of the following is the incorrect description of the internal port properties of the Ethernet board?

• A.For the ingress port of the Access attribute, if the input data does not carry the VLAN ID, it is directly transparent.
• B.For the ingress port for the Access attribute, if the input data carries the VLAN ID, discard.
• C.For the ingress port of the Tag Aware attribute, if the input data does not carry the VLAN ID, discard.
• D.For the inbound port of the Tag Aware attribute, if the input data carries the VLAN ID, transparently receive the data.
