Which statement best describes phase synchronization as it is used in the backhaul transport?

  1. The master and slave clocks cycle at a rate within 50 parts per billion (ppb)
  2. The master and slave clock frames start within +/- 500 nanoseconds
  3. The slave clock sets its clock frequency to the incoming bit rate
  4. The slave sets its time and date accordingly to the arriving packet rate

Answer(s): B



Which command example correctly configures a 7750 Service Router (SR) for Synchronous Ethernet (SyncE) support?

  1. configure card 1 mda 1 sync-e
  2. configure card 1 ethernet sync-e
  3. configure system sync-if-timing sync-e no shutdown
  4. configure port 1/1/1 ethernet sync-e no shutdown

Answer(s): A



Which component must you configure on an IEEE 1588v2/Precision Time Protocol (PTP) v2 slave to enable it to choose its master based on Synchronization Status Message (SSM) Option 1 or Option 2 Quality Levels?

  1. Set the PTP port to the desired ITU-T G.781 Option 1 or 2 mode
  2. Set the SROS IEEE 1588v2 profile to IEEE 1588-2008
  3. Set the SROS IEEE 1588v2 profile to ITU-T G.8265.1
  4. Configure ql-override on the PTP reference entry

Answer(s): C

Consider the topology and MLS1 configuration shown, and given the following conditions:
· MLS1 delivers the PRC traceable clock to the network · Reference 1 receives Quality Level (QL) - PRS
· Reference 2 receives QL - DUS
· BITS sets QL-STU
Which quality level will MLS1 deliver to POC2-1 on its Synchronous Ethernet (SyncE) port 1/2/7?

  1. QL-DUS
  2. QL-EEC2
  3. QL-PRS
  4. QL-STU

Answer(s): C

Based on the default SROS Border Gateway Protocol (BGP) timer settings and the configuration shown:
If the Interior Gateway Protocol (IGP) removes its route to the BGP neighbor 192.0.2.2, how long will BGP wait to drop its peering session with that neighbor router?

  1. 0 seconds
  2. 30 seconds
  3. 90 seconds
  4. 170 seconds

Answer(s): C
