RSVP-TE is the RSVP extended in traffic engineering sense. What are the major functions of RSVP TE?

• LSP setup and deletion
  
• LSP attribute modification
  
• LSP rerouting
  
• LSP optimization
  
• LSP bandwidth Management
  

A service created using the trail function will not become a discrete service.

• TRUE
  
• FALSE
  

Which of the following operations are required for monthly basic maintenance on the U2000?

• Checking for the time of the U2000 server
  
• Backing up system files
  
• Changing the password for a current user
  
• Checking operating system logs
  

What may cause the HP_LOM alarm?

• Services are not configured on upstream NEs.
  
• The service level is set inconsistently at both ends.
  
• The C2 byte to be transmitted on the terminal NE is 0x00, and the pass-through NEs are set to pass through the overhead.
  
• The board (for example, a cross-connect board) is faulty, resulting in loss of the H4 byte or incorrect H4 byte.
  

During normal operation of a network, the conditions that trigger a protection switching are generated on the working channel but services fail to be automatically switched to the protection channel. Services are interrupted, but the MS protocol status is normal on the NMS. What are the possible causes?

• Incorrect fiber connections between boards
  
• The cross-connect or line board is faulty.
  
• The configuration data on the NE and those on the NMS are inconsistent. As a result, the parameters of MSP nodes do not take effect.
  
• Equipment power failure
  
• The SCC board is faulty.
  

Which of the following about the conditions that trigger rerouting on NG-SDH equipment?

• R_LOS, R_LOF
  
• RSBBE, MSBBE
  
• MS_AIS, MS_RDI
  
• AU_AIS, AU_LOP
  
• HP_UNEQ, HP_LOM
  

On a normal network, clock protection switching fails after the clock synchronization path is interrupted. As a result, lots of pointer justification events occur on related NEs. What are the possible causes for the failure of clock protection switching?

• Incorrect fiber connections between boards
  
• Optical power is incorrect.
  
• The clock tracing modes are incorrect.
  
• The network-wide clock protection switching protocols are incorrectly configured.
  
• Hardware faults
  

What is the value of an AU-FTR pointer without frequency or phase difference?

• 0
  
• 521
  
• 522
  
• 782
  

Which of the following statements are true about fiber-shared virtual path protection?

• The VC-4 timeslots of an optical path allocated to an MSP ring and those allocated for an SNCP ring must be different.
  
• When the VC-4 timeslots of an optical path allocated to both an MSP ring and an SNCP ring are the same, services on the VC-4 timeslots have double protection.
  
• The VC-4 timeslots of an optical path allocated to two MSP rings must be different.
  
• When the VC-4 timeslots of an optical path allocated to two MSP rings are the same, services on the VC-4 timeslots have double protection.
  
• The VC-4 timeslots of an optical path allocated to two SNCP rings must be different.
  
• When the VC-4 timeslots of an optical path allocated to two SNCP rings are the same, services on the VC-4 timeslots have double protection.
  

The physical cross-connect board of an OSN 3500 is N1SXCS

• Which of the following can be configured as the logical board for N1SXCSA?
  
• N1SXCSA
  
• N1EXCSA
  
• N1UXCSA
  
• N2SXCSA
  
• N2EXCSA
