Which practice helps ensure continuity of critical communications during an incident?

• A. Relying on a single communication channel.
• B. Waiting for external vendors to respond.
• C. Disallowing maintenance during incidents.
• D. Having redundant systems.

Answer: (D)

Having redundant systems is about building backups into your communications so messages can still get through even if one path fails. This creates continuous reach to incident command and responders by automatically switching to alternate channels, power sources, or network routes when the primary one is disrupted. For example, using multiple modes of communication (radio, cellular, satellite), plus backup power and off-site data centers, helps ensure messages aren’t cut off during an incident. Relying on a single channel risks a total outage if that channel fails, waiting for external vendors can introduce delays when time is critical, and strict maintenance restrictions during incidents reduce resilience. Redundancy keeps critical communications flowing under stress.
