What activation level is implemented when only certain EOC team members monitor a credible threat?

The correct answer is that the activation level implemented when only certain Emergency Operations Center (EOC) team members monitor a credible threat is the Enhanced Steady-State level. This level indicates that while there is potential for an incident or threat, it does not require full activation of all EOC resources and personnel. Instead, key team members are still on duty to assess and manage the situation, ensuring an informed and coordinated response should the threat escalate.

This approach allows for a balanced response, where critical assessment and monitoring occur without overwhelming the system. It effectively keeps the team prepared for increased activity while managing resources efficiently. The other levels of activation either signify a status of normal operations, full engagement of all teams in a crisis, or a transition to recovery, which do not apply in this scenario.
