Guaranteed - A+ Graded
Section 1: NIMS Fundamentals & Command Structures (Questions 1–10)
Q1: A Category 3 hurricane is approaching the coast. The Incident Commander has established an ICP at
a high school. Evacuation orders are in effect. Multiple jurisdictions (county, three cities, state police)
are responding. An EOC has been activated. The Planning Section needs to develop the Incident Action
Plan for the next operational period. Who should approve the IAP before implementation?
A. The Emergency Operations Center Director
B. The Planning Section Chief
C. The Incident Commander [CORRECT]
D. The Multi-Agency Coordination Group
Correct Answer: C
Rationale: Under NIMS ICS principles, the Incident Commander (IC) has sole authority to approve the
Incident Action Plan (IAP) before implementation. The IC establishes incident objectives and manages all
incident operations. Option A is incorrect because EOCs coordinate support and resource allocation but
do not approve tactical IAPs—that authority rests with the IC at the incident level. Option B is incorrect
because while the Planning Section Chief develops and assembles the IAP, they do not have approval
authority. Option D is incorrect because MAC Groups operate at the policy/strategic level and set
priorities but do not approve operational-level IAPs.
Q2: During a major wildfire response, five agencies are operating under separate Incident Commanders
within the same geographic area. Resources are being duplicated, and jurisdictional conflicts are
emerging. Which NIMS component addresses this coordination challenge?
A. Unified Command
B. Area Command [CORRECT]
C. Multi-Agency Coordination System
D. Joint Information Center
,Correct Answer: B
Rationale: Area Command is established when multiple ICPs are operating in close proximity or when
incidents are of similar type and/or competing for resources. Area Command oversees multiple ICPs,
coordinates resource allocation between incidents, and ensures efficient management without
assuming tactical command. Option A is incorrect because Unified Command involves multiple agencies
sharing command at a single incident, not coordinating multiple separate incidents. Option C is incorrect
because MAC Systems operate at the policy/strategic level above field operations, not between multiple
ICPs. Option D is incorrect because JICs handle public information coordination, not operational
command coordination.
Q3: Which of the following is NOT one of the five major NIMS components?
A. Preparedness
B. Communications and Information Management
C. Command and Coordination
D. Hazard Mitigation [CORRECT]
Correct Answer: D
Rationale: The five NIMS components are: Preparedness, Communications and Information
Management, Resource Management, Command and Coordination, and Ongoing Management and
Maintenance. Hazard Mitigation is a phase of emergency management but is not a NIMS component.
Options A, B, and C are all legitimate NIMS components as defined in the October 2017 NIMS document.
Q4: A chemical spill occurs at a manufacturing facility. The plant manager, local fire chief, and EPA on-
scene coordinator all have statutory authority and arrive simultaneously. Which ICS command structure
allows all three to maintain their agency authority while establishing a single command structure?
A. Single Command
B. Unified Command [CORRECT]
C. Area Command
D. Dual Command
Correct Answer: B
Rationale: Unified Command allows agencies with different jurisdictional responsibilities or statutory
authorities to jointly manage an incident while maintaining their own authority. All participating
agencies' authorities are recognized, and decisions are made collectively. Option A is incorrect because
Single Command involves only one IC with complete authority. Option C is incorrect because Area
Command oversees multiple incidents, not multiple authorities at one incident. Option D is incorrect
because "Dual Command" is not a recognized NIMS/ICS term—Unified Command is the correct
terminology for multiple agencies sharing command.
, Q5: According to NIMS, what is the optimal span of control for any supervisor within the ICS
organization?
A. 3 subordinates
B. 5 subordinates [CORRECT]
C. 7 subordinates
D. 10 subordinates
Correct Answer: B
Rationale: NIMS ICS establishes that span of control should range from 3 to 7 subordinates per
supervisor, with 5 being the optimal number. This ensures effective supervision while maintaining
organizational efficiency. Option A is within range but represents the minimum, not the optimal. Option
C is within range but represents the upper limit. Option D exceeds the maximum span of control and
would violate ICS organizational principles.
Q6: Which Homeland Security Presidential Directive mandated the establishment of NIMS and requires
federal departments and agencies to adopt NIMS and use it in their incident management programs?
A. HSPD-3
B. HSPD-5 [CORRECT]
C. HSPD-7
D. HSPD-8
Correct Answer: B
Rationale: Homeland Security Presidential Directive-5 (HSPD-5), issued February 28, 2003, mandated
the establishment of NIMS and requires federal departments and agencies to adopt NIMS and use it in
their incident management programs. It also requires state, tribal, and local organizations to adopt
NIMS to receive federal preparedness assistance. Option A (HSPD-3) addresses the Homeland Security
Advisory System. Option C (HSPD-7) addresses critical infrastructure identification and protection.
Option D (HSPD-8) addresses national preparedness.
Q7: During a complex flooding incident, the Incident Commander delegates full authority for the
incident to the Deputy Incident Commander and departs for a pre-scheduled conference. Which
statement about this transfer of command is correct?
A. This is an appropriate use of transfer of command
B. Transfer of command requires written documentation and briefing [CORRECT]
C. The Deputy automatically assumes command when the IC leaves
D. Transfer of command is only used at the end of an incident
