Which protection level includes designated critical space and resources?

Which protection level includes designated critical space and resources?

• A. PL-1
• B. PL-4
• C. PL-3
• D. PL-2

Answer: (B)

Protection levels classify assets by how critical they are to the mission, guiding what safeguards are required. When space and resources are designated as critical, they’re placed at the highest protection level. That level brings stringent safeguards: access is tightly restricted to authorized personnel, physical security measures are intensified, environmental and power redundancy are implemented, and monitoring and incident response are emphasized to detect and recover quickly from any disruption. The aim is to prevent any loss or compromise that would have a severe impact on operations. Other protection levels exist (PL-1 through PL-3), each with progressively less stringent controls for assets with lower impact. So designated critical space and resources fall under the top tier, PL-4.
