Q1A station rule states: 'Any vehicle entering the secured lot must display a valid parking decal.' Agent Lopez sees a truck in the secured lot with no decal. Based ONLY on this rule, what can be concluded?
Show answer
✓ Correct answer: The truck is in violation of the parking rule
The rule requires a valid decal for any vehicle in the lot. A vehicle with no decal therefore violates the rule. The other choices add facts the rule does not supply.
Q2Policy: 'Detainees must be searched before being placed in a holding cell.' An agent is about to place a detainee in a cell. According to policy, what must happen first?
Show answer
✓ Correct answer: The detainee must be searched
The policy states a search must occur before cell placement, so the search is the required prior step. The other actions are not mentioned by the rule.
Q3Policy: 'Firearms must be unloaded and secured in the gun locker before an agent enters the detainee processing area.' Agent Kim is entering processing with a loaded firearm. What is the correct conclusion?
Show answer
✓ Correct answer: Kim is violating policy and must secure the firearm first
The policy requires the firearm to be unloaded and locked before entering. A loaded, unsecured firearm violates the policy, so Kim must secure it first.
Q4All agents at Station 7 completed firearms qualification. Officer Hale is an agent at Station 7. What follows?
Show answer
✓ Correct answer: Hale completed firearms qualification
If all Station 7 agents qualified and Hale is one, then Hale qualified. This is a valid categorical deduction.
Q5No expired ID may be used to cross the checkpoint. The traveler's ID is expired. What must be concluded?
Show answer
✓ Correct answer: The traveler's ID may not be used to cross
Because no expired ID may be used and this ID is expired, it follows necessarily that this ID may not be used to cross.
Q6If a sensor triggers, then an agent is dispatched. An agent was NOT dispatched at 3 a.m. What can be validly concluded about 3 a.m.?
Show answer
✓ Correct answer: No sensor triggered at 3 a.m.
The contrapositive of 'if triggered then dispatched' is 'if not dispatched then not triggered.' Since no agent was dispatched, no sensor triggered.
Q7An agent concludes a driver was speeding. Which single piece of information would BEST support that conclusion?
Show answer
✓ Correct answer: A calibrated radar reading above the posted limit
A calibrated radar reading directly measures speed against the limit, which is the relevant fact. Nervousness, car type, and time of day do not establish speed.
Q8To conclude that a package contains contraband rather than only suspect it, which evidence is strongest?
Show answer
✓ Correct answer: A physical inspection revealed the contraband inside
A direct inspection that finds the contraband is conclusive evidence. The other items are weak circumstantial cues that do not prove contents.
Q9An agent wants to prove a specific vehicle crossed the checkpoint at 2:14 p.m. Which evidence is most sufficient?
Show answer
✓ Correct answer: Timestamped checkpoint camera footage of that vehicle's plate at 2:14 p.m.
Timestamped footage of the plate directly establishes the vehicle and the time. Similar-vehicle impressions, registration, and ownership do not pin down this crossing event.
Q10Which statement, if proven, is sufficient to conclude that a detainee is NOT the person named in an arrest warrant?
Show answer
✓ Correct answer: The detainee's verified fingerprints do not match the warrant subject's prints
Non-matching verified fingerprints establish a different identity, which is sufficient. A denial, a common name, or demeanor do not prove identity either way.
