The correct answer is A. Enable "ql-override prs" on the BITS reference. See the full explanation below for the reasoning.
Question
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?
Options
- AEnable "ql-override prs" on the BITS reference
- BEnable "ql-override prc" on the master's SyncE ports
- CEnable "ql-selection prs" on the BITS reference
- DSet the master router to choose its source by quality level
