B. Inter-ring services are protected even if an intersecting node is not configured with unidirectional cross-connections.
C. Generally, a tangent node is configured with two SNCP protection groups, two unidirectional cross-connections, and the other intersecting node is configured with two bidirectional cross-connections.
What are required to collect networking information during daily equipment maintenance of MSTP equipment?
A. Obtain the network topology diagram.
B. Check whether the network involves interconnection with third-party equipment. If such interconnection exists, check for configuration precautions and compatibility requirements.
C. Obtain engineering design documents, including slot diagrams, fiber connection diagrams, mapping between NE name, NE ID, and NE IP addresses, equipment room layout, and ODF/DDF port distribution diagrams.
D. Obtain historical information blocks of preventive maintenance inspection.
E. Obtain equipment data backup information.

C. RSVP-TE
D. CSPF
A network on which ASON is to be enabled has been configured with transparent transmission of DCC bytes for third-party equipment. Which of the following is true?
A. Do not enable ASON for the network, regardless of whether inband or outband DCN is used.
B. You can enable ASON for the network, regardless of whether inband or outband DCN is used.
C. You can enable ASON for the network when inband DCN is used.
D. You can enable ASON for the network when outband DCN is used.

C. By default, VC-4-level services are terminated.
D. For VC-4-level services, overhead processing mode is configurable.
E. For VC-12/VC-3-level services, overhead processing mode is not configurable.
The cross-connection resources used by discrete services cannot be used to create other services. All discrete cross-connections must be deleted.
A. TRUE
B. FALSE
When measured rate is smaller than or equal to throughput, frame forwarding latency can be classified by data type into store-and-forward latency and what?
A. Cut-through latency
B. Bit processing delay
C. Bit transmission delay
