Four network elements A, B, C, and D form a two-fiber bidirectional multiplex section shared protection ring, and there are a large number of PDH services between A and B.
One day, the fiber between A and B was interrupted. In order to eliminate the R-LOS alarm on the network management system, an engineer self-looped the optical ports at both ends of the interrupted fiber. After 10 minutes by default, what will happen?

• A.  The services of A and B will not be affected, and the switching alarm will not disappear
• B.  The business between A and B is not affected, and the switching alarm disappears
• C.  The service between A and B is interrupted, and the switching alarm does not disappear
• D.  The service between A and B is interrupted, and the switching alarm disappears

The two MSP rings intersect, and one of the network elements at the intersection point has the coexistence of SNCP and MSP protection. How can I solve the secondary switching phenomenon due to the coexistence of protection?

• A.  Set delay time when configuring SNCP cross connection
• B.  No need to set a delay time
• C.  Set the delay time when configuring the MSP cross-connect
• D.  It is necessary to set the delay time when configuring MSP and SNCP

An operator needs to configure 60 clients, 200 OptiX PTN 1900, 100 OptiX OSN 3800 (With ASON), 150 NE40E, 200 CX600 series equipment, and the access side is equipped with FTTx OLT and MDU, a total of 80,000 xDSL lines , 70,000 lines of PSTN ports, 30 OLTs and 300 MDU devices are deployed.
Regarding the description of this network, the error is:

• A.  The number of equivalent network elements for 100 OptiX OSN 3800 (With ASON) is 350
• B.  The number of physical network elements to be managed by the network management center is 980
• C.  In practice, 50% of the current network size needs to be reserved for expansion capacity
• D.  The network is a medium-scale network

In general, which PHB is the signaling flag?

• A.  AF1, AF2, AF3, AF4
• B.  CS7, CS6
• C.  EF
• D.  BE

Throughput refers to the maximum rate of the network without frame loss. During the test, the test starts from the maximum line rate frame rate Xmax that the device can support. When the device starts to lose frames, reduce the frame rate. When the device does not lose frames Time, increase the frame rate

• A.  TRUE
• B.  FALSE
