What is the primary purpose of predefined sequences for backup components in CSOSS?

• A. To reduce operator workload by automating all decisions.
• B. To ensure continuity of operation and prevent loss of function.
• C. To confuse the operator during crisis.
• D. To eliminate the need for monitoring.

Answer: (B)

The main idea being tested is how predefined sequences support mission continuity by guiding action when a backup component must take over. These sequences are designed to keep critical systems functioning despite a fault, providing a tested, standard path to switch to a backup, verify it’s operating, and restore essential capabilities quickly. That focus on maintaining operation and preventing loss of function helps crews respond efficiently under stress and reduces the chance of missed steps or cascading failures.

This isn’t about automating every decision or removing human judgment; there’s still operator involvement, and the steps are there to ensure the backup path is executed correctly and safely. It also isn’t about eliminating monitoring—checking system status and confirming that the backup is online and healthy remains essential.
