Demo Questions

Question 1

If an IEEE 1588v2/Precision Time Protocol (PTP) v2 slave times out announce messages with the master, to which state does the slave port transition to choose another potential master?

Initial
Listening
Passive
Un-calibrated

Correct answer: B

Question 2

Given the configuration shown and the following conditions:

The external reference is offline
Reference 1 receives Quality Level (QL) - EEC1
Reference 2 receives QL - SSU-A

Which quality level will the SAR router advertise to its Synchronous Ethernet (SyncE) peers?

QL-DNU
QL-EEC1
QL-SSU-A
QL-PRC
QL-UNC

Correct answer: B

Question 3

Given the show command results shown:

Which IEEE 1588v2/Precision Time Protocol (PTP) v2 parent clock value does the slave first consider when choosing its master?

GM Clock Priority1
GM Clock ID
GM Clock Priority2
GM Clock Class

Correct answer: D

Question 4

An SROS router obtains its timing exclusively from its BITS input port. The router sets Quality Level (QL) SONET Traceability Unknown (STU) on this Superframe (SF) framed DS1 BITS reference.

What must you configure on this master router to pass the best clock quality level to the downstream Synchronous Ethernet (SyncE) slave nodes while maintaining traceability to the DS1 source?

Enable "ql-override prs" on the BITS reference
Enable "ql-override prs" on the master's SyncE ports
Enable "ql-selection prs" on the BITS reference
Set the master router to choose its source by quality level

Correct answer: A

Question 5

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) - EEC1
Reference 2 receives QL - SSU-A
BITS sets QL-SSU-B

Which quality level will MLS1 deliver to POC2-1 on its Synchronous Ethernet (SyncE) port 1/2/7?

QL-EEC1
QL-PRC
QL-SSU-A
QL-STU

Correct answer: B

Question 6

Which synchronization technique supports time of day and phase synchronization?

IEEE 1588 v2/Precision Time Protocol (PTP) v2
Adaptive Clock Recovery (ACR)
Time Division Multiplexing (TDM) line timing
Synchronization Ethernet (SyncE)/Synchronization Status Message (SSM)

Correct answer: A

Question 7

Which is a characteristic of the IEEE 802.3 Slow Protocol?

There are a maximum of 10 frames transmitted per second
There are a maximum of 20 slow protocol subtypes per interface
The maximum slow protocol frame size is 64 bytes
The slow protocol header carries the clock quality level

Correct answer: A

Question 8

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

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

Correct answer: B

Question 9

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

configure card 1 mda 1 sync-e
configure card 1 ethernet sync-e
configure system sync-if-timing sync-e no shutdown
configure port 1/1/1 ethernet sync-e no shutdown

Correct answer: A

Question 10

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?
