, SYSTEM SECURITY AND AUTHORIZED ACCESS
Q1. A newly hired dispatcher is being granted access to the CLEAN system for the first time. The agency terminal agency
coordinator (TAC) must complete which step before the operator can perform any inquiries?
A. Assign a generic shared password that rotates every 90 days
B. Verify completion of CLEAN/NCIC training and create a unique user ID with documented authorization
C. Allow the operator to use a supervisor’s logon until individual credentials are issued
D. Grant temporary access without training if the operator has prior experience in another state
Correct Answer: B
Rationale: CLEAN and NCIC policy require that every operator complete approved training and receive an individual, uniquely
identifiable user ID before any access is granted. Shared or temporary credentials violate security standards and audit requirements.
Q2. An operator notices that a co-worker has left a CLEAN terminal logged in and unattended in a public area of the
communications center. What is the correct immediate action?
A. Continue using the terminal under the co-worker’s session to save time
B. Log the terminal off and notify the Terminal Agency Coordinator of the security violation
C. Leave the session open but cover the screen with a privacy filter
D. Change the password while the session is still active
Correct Answer: B
Rationale: Unattended logged-in terminals create a serious security risk. Policy requires immediate log-off and reporting so that the
TAC can document the incident and reinforce proper session control.
Q3. A CLEAN operator receives a request from a private investigator to run a criminal history query for a civil background
check. The operator should:
A. Perform the query using purpose code C because the request is for a criminal justice purpose
B. Refuse the request because private investigators are not authorized users of CLEAN/NCIC
C. Run the query and bill the investigator for the service
D. Forward the request to the FBI for processing
Correct Answer: B
Rationale: CLEAN/NCIC access is restricted to authorized criminal justice agencies and personnel. Private investigators and other
non-criminal-justice entities may not obtain information through the system.
Q4. During a routine security audit, the TAC discovers that an operator’s password has not been changed for 14 months.
Which action is required?
A. No action is needed because passwords never expire once issued
B. Force a password change immediately and document the compliance action
C. Disable the account permanently without notice
D. Allow the operator to continue using the same password if no breaches have occurred
Correct Answer: B
Rationale: CLEAN security policy mandates regular password changes. An expired or overdue password must be reset promptly and
the corrective action recorded for audit purposes.
Q5. An operator is asked by a patrol officer to query CLEAN for a vehicle registration while the officer is on a traffic stop.
The officer provides only a partial plate number and no other identifiers. The operator should:
A. Run a wild-card query on the partial plate and return all possible matches
B. Advise the officer that additional identifiers are required for a valid inquiry and request more information
C. Refuse to run any query until a full plate is provided
D. Enter the partial plate into the system using a fictitious state code
Correct Answer: B
Rationale: Accurate and complete identifiers improve hit quality and reduce false positives. Operators must request sufficient
information rather than conducting overly broad or speculative queries.
