Which of the following descriptions about PW APS bundling are correct? (multiple choice)
A. When the PW APS protection group is switched, its subsidiary protection pair also undergoes the same switching.
B. When the PW APS protection group is switched, its subsidiary protection pairs will not undergo the same switching.
C. When the status of the PW APS slave protection pair changes, it will cause the status of the PW APS protection group to change.
D. When the status of the PW APS slave protection pair changes, it will not cause the status of the PW APS protection group to change.
正解：A,D
質問 2：
PTN equipment realizes the unified bearing of multiple services through PWE3. For users, the PTN equipment is equivalent to a Layer 2 switch at this time.
A. TRUE

正解：A
質問 3：
Add a new single-board TOA on the live network 8800 (version R7C02SCP300), the network manager queries the TOA single-board software and cannot automatically match the R7 version of the master. The possible reason is (multiple choice)
A. 8800 equipment automatic matching software function is closed
B. The original main control of the 8800 device is a customized package, and there is no software for the TOA board, so the version cannot be automatically matched
C. TOA's software version is higher than the live network version, so it cannot be automatically matched
D. The 8800 device does not have the function of automatic matching software, and the software package needs to be reloaded
正解：A,B
質問 4：
The non-linear effect of the coherent signal is stronger than that of the 10G non-coherent, so the single-wave entering fiber optical power should be reduced. Therefore, during system commissioning, the OA gain can be reduced to reduce the single-wave output optical power of the OA to meet the fiber-in optical power requirements.
A. TRUE
B. FALSE
正解：B
質問 5：
What are the precautions for configuring MPLS Tunnel on Hybrid MSTP? (multiple choice)
A. In the same network, the LSR IDs of all network elements cannot be the same
B. The IPs of the ports at both ends of the same link must be in the same network segment
C. The IP address of the Ethernet port of the same network element cannot be in the same network segment
D. In the same network, the MPLS labels of all network elements cannot be the same
正解：A,B,C
質問 6：
If the meter sending data frame rate is X and receiving data frame rate is Y, then the packet loss rate = (XY) /X*100%, usually the packet loss rate + throughput = 1
A. TRUE
B. FALSE
正解：A
