Once an IEEE 1588v2/Precision Time Protocol (PTP) v2 clock is configured and turned up, to which state do the ports transit on first in order to wait for announcements from the Master?
Answer(s): B

Answer(s): C
Click on the exhibit.Considering the configuration shown, and given the following conditions:* The 7705 Service Access Router (SAR) is a Precision Time Protocol (PTP) v2 master on domain 1* It is configured for the ITU-T G.8265.1 profile* ref1 is an Extended Superframe (ESF) DS1 and is qualified* The DS1 source indicates in its SSM messages that it is synchronized to a Stratum 3 clock* ref2 is a Synchronous Ethernet (SyncE) port and traces its source to a Stratum 1 reference Which Quality Level will the 7705 SAR master announce to its slave routers?
Answer(s): D
