Question #181
Which of the following options does not belong to the PW APS switching conditions?
- A . Single board software failure
- B . MPLS_PW_SF
- C . Single board hard reset
- D . Single board soft reset
Question #182
XPIC can be used in conjunction with ATPC, but this is generally not recommended.
If it is necessary to use it together, what should I pay attention to? (Multiple choice)
- A . When used with AM, set the ATPC upper threshold to the lower threshold plus 5dB.
- B . The horizontal polarization direction link and vertical polarization direction link of a group of XPICs should be configured with the same ATPC parameters (ATPC enable, RATPC adjustment threshold)
- C . Set the ATPCE lower threshold difference as small as possible, 5dB is recommended
- D . Set the ATPC lower threshold to be greater than the planned AM sensitivity in full-capacity modulation mode plus 14 dB.

Question #185
A. When gold services exist in a SON network, multiplex section planning is required. Which of the following statements about multiplex section planning are correct? (Multiple choice)
- A . The multiplexing segment should cover all nodes that need to be configured with gold-level services. For complex networks, multiple multiplexing segments can be used to cover
- B . Services within the same multiplexing segment should be distributed as evenly as possible. Try to avoid the situation where some sections of a multiplexing segment have high bandwidth utilization while other sections have low bandwidth utilization.
- C . If there are few gold-level services, then configure diamond-level services instead of gold-level services.
- D . If the gold service does not occupy half of the optical path resources, try to configure it to occupy part of the VCA segment, that is, part of the multiplexing segment.
Question #186
Which of the following are communications, quality alerts? (Multiple choice)
- A . Optical port loopback
- B . No user logged in to the network element
- C . NE Communications
- D . Loss of optical signal
