Question 245:
Which are the two fundamental ways in which IEEE 1588 differs from SyncE? (Choose two.)
Answer options:
A. In addition to frequency synchronization, it achieves ToD synchronization to achieve phase alignment which is required for multi-channel communication. B. It is a purely-based solution, with the actual clock values being passed inside the payloads of special packets dedicated to that task. C. It offers two major changes over traditional Ethernet to make it suitable for clock distribution: a mandated clock accuracy and the ESMC protocol for clock selection, distribution, management, traceability, and failover. D. SyncE is a Cisco proprietary ToD technology where IEEE 1588 is a industry standard recommended for interoperability across vendor devices. E. IEEE 1588 applies to voice-only systems or with low-bandwidth data traffic.
