Question 6
During an operational period on a multi-day search and rescue
mission, a task force leader manages 4 search squads, 1 canine unit,
and 1 drone operator team. How does this organizational structure
align with standard ICS Span of Control guidelines?
A. It exceeds the maximum allowable limit of 5 subordinate resources.
B. It falls within the optimal manageable ratio of 1 supervisor to 3–7
subordinates (ideally 1 to 5).
C. It violates unity of command by mixing technical canine and drone

D. It represents an invalid span of control because task forces cannot
manage canine units.
🔴 Correct Answer: B. It falls within the optimal manageable ratio
of 1 supervisor to 3–7 subordinates (ideally 1 to 5).
🔵 Explanation: ICS span of control guidelines establish an optimal
supervisory ratio of 1 supervisor to 5 subordinates, though a range
between 1 to 3 and 1 to 7 is acceptable depending on complexity.

agencies are integrated and consistent?
A. Incident Command Post (ICP) Press Room
B. Joint Information Center (JIC)
, C. Emergency Operations Center (EOC) Media Desk
D. Liaison Officer Desk
🔴 Correct Answer: B. Joint Information Center (JIC)

commitments.
🔵 Explanation: Transfer of command protocol requires a
comprehensive briefing (verbal, written, or using ICS Form 201)
detailing incident status, safety hazards, priorities, and assigned
resources.
Question 9
An emergency response agency responds to a structural fire in an
industrial park. When setting up plain language radio communications
across multi-agency channels, which practice is explicitly prohibited
under NIMS ICS standards?
A. Utilizing clear text radio terminology
B. Standardized resource designations
C. Using agency-specific 10-codes and jargon
D. Pre-established channel allocations
