In a data-link outage, which alternative communications path is typically used in BCC operations?

• A. Primary fiber link.
• B. None; communications are paused.
• C. Direct satellite feed from a central hub only.
• D. Redundant data links or secure landlines, radio networks, or satellite communications.

Answer: (D)

When the data-link is down, BCC operations rely on diverse, independent communication paths to keep command and control alive. The idea is redundancy: using several different media so a failure in one path doesn’t cut off all communications. In practice, this means switching to or having ready access to secure landlines, radio networks, or satellite communications, and sometimes multiple redundant data links. These backup channels are designed to withstand outages that affect the primary fiber link and maintain connectivity across the network.

The other options don’t fit because relying on the primary fiber link isn’t possible during an outage, having no communications isn’t workable for operations, and a single direct satellite feed from the central hub is too limited and vulnerable if that hub or its link is compromised. The best answer reflects the use of multiple redundant paths across different technologies to preserve communications.
