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

• A.  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.
• B.  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.
• 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.  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.

What are the prerequisites for creating a bidirectional MPLS tunnel? (Multiple Choice)

• A.  Users have network administrator user rights of "Administrators" and above
• B.  Port properties have been configured correctly
• C.  Determine the bandwidth of the MPLS Tunnel
• D.  The LSR ID of each NE is correctly configured.

Which of the following are limitations of the alarm and performance analysis methods? (Multiple Choice)

• A.  When some faults occur, there may be no obvious alarms or performance events reported, and sometimes no alarms or performance events are found.
• B.  Field maintenance personnel cannot understand the current operating condition of the equipment.
• C.  In the case of complex networking, service, and fault information, many alarms and performance events may occur along with the occurrence of faults. Due to too many reports and performance events, maintenance personnel are unable to analyze.
• D.  The network administrator cannot obtain the current notifications of the device, the alarm occurrence time, and the historical alarm of the device.
