The OSSV agent on the primary system listens to TCP port 10000 for all SnapVault communications.

• A. True
• B. False
• C. NA
• D. NA

Answer: (A)

The essence here is that the OSSV agent on the primary system is the endpoint for SnapVault communications, and it uses a fixed TCP port to do that. Port 10000 is the designated channel through which the OSSV agent accepts and coordinates SnapVault sessions. When a SnapVault backup or transfer is initiated, the partner system connects to the primary’s OSSV port 10000, the session is established, and the data and control messages flow over that channel. This fixed port makes firewall and ACL configuration straightforward, ensuring reliable communication for all SnapVault operations. So, the statement is correct. If you ever run into connectivity issues, checking that TCP port 10000 is accessible to the partner system is a common troubleshooting step.
