Which SOS subsystem provides software support for the site and site-to-site data communication for software distribution?

• A. Terminal Automation Subsystem (TAS)
• B. Site Support Subsystem (SSS)
• C. Monitor and Control Subsystem (MCS)
• D. Operational Data Subsystem (ODS)

Answer: (B)

The question is about which SOS subsystem is responsible for moving software and data between sites to support software distribution. The Site Support Subsystem is designed for exactly that: providing software support for each site and handling the site-to-site data communication needed to distribute software packages. It acts as the communications and coordination layer that ensures remote sites receive updates, configurations, and other software content reliably.

Other subsystems have different roles: Terminal Automation Subsystem focuses on automating terminal operations, Monitor and Control Subsystem handles real-time monitoring and control of equipment and processes, and Operational Data Subsystem manages operational data storage and access. None of these are primarily about distributing software between sites, which is why the Site Support Subsystem is the correct choice.
