Router
Switch
Firewall (Correct answer)
Proxy Server

Correct answer: Firewall

Explanation: Firewall is the correct answer because the provided entries represent firewall rules that allow or deny specific types of traffic based on source, destination, and port numbers. In this case, the entries permit traffic on ports 80 (HTTP) and 443 (HTTPS) while denying all other traffic. This configuration is commonly found in firewall devices, which enforce security policies by filtering and controlling network traffic based on defined rules.

H
F
D (Correct answer)
B
A
G
E
C

Confirmation bias
Mirror imaging
Availability heuristic
Anchoring bias (Correct answer)

Correct answer: Anchoring bias

Question 35: In the item below, try to visualize the shape that would complete the matrix, based on the pattern(s) of shapes.

B
D
F
H
A
E
C
G (Correct answer)

Correct answer: G

Explanation: To decide what is in the missing cell, look at the two cells in the bottom row. Both contain an X, so the missing cell should have an X. The arrow only appears in the left column, so it will not be in the right column. So, the correct response is Option G, because it contains an X, but not an arrow.

Question 36: When an intelligence analyst uses 'probability language' such as 'likely' or 'probably,' what standardized meaning does this convey under IC Directive 203?

The event depends entirely on a foreign adversary's stated intentions
The event has already been confirmed by multiple independent sources
The analyst cannot confirm or deny the event occurred
The assessed probability is roughly 55–80 percent (Correct answer)

Ensuring data integrity
Supporting non-repudiation (Correct answer)
Enhancing confidentiality
Facilitating access control

Correct answer: Supporting non-repudiation

Explanation: Supporting non-repudiation is the primary use case for mandating the use of digital signatures. Digital signatures provide a way to verify the authenticity and integrity of electronic documents or messages, thereby ensuring that the sender cannot later deny having sent the message or document. This helps establish accountability and trust in electronic transactions within the organization.

F
D (Correct answer)
B
E
A
H
G
C

Correct answer: D

Explanation: The correct answer is D. The second image in each row is the result of moving the three shapes in the first image in each row closer together, and the third image in the first two rows is the result of placing the shapes from the first image in each row inside each other. Thus, the third image in the bottom row must have the shapes from the first image in the bottom row inside each other.

Question 58: What is the first step of the five-step OPSEC process?

Examining a problem through successive analytical lenses — tactical, operational, and strategic — to build a complete picture (Correct answer)
Using geospatial overlays to combine satellite and signals data
Distributing analytic work across multiple agencies to prevent duplication
Applying multiple classification levels to a single report

Correct answer: Examining a problem through successive analytical lenses — tactical, operational, and strategic — to build a complete picture

Layered analysis ensures that intelligence assessments account for immediate tactical details, mid-level operational context, and broader strategic trends rather than being confined to a single level of analysis.

Red Team Analysis
Analysis of Competing Hypotheses (ACH) (Correct answer)
Link Analysis
Key Assumptions Check

Correct answer: Analysis of Competing Hypotheses (ACH)

HUMINT is the only collection method that can operate in denied areas
HUMINT can access intentions, plans, and context that technical systems often cannot capture (Correct answer)
HUMINT is faster and cheaper than all technical collection methods
HUMINT produces more precise geolocation data than SIGINT

Correct answer: HUMINT can access intentions, plans, and context that technical systems often cannot capture

Human sources can report on an adversary's intentions, leadership thinking, and unspoken plans — information that technical systems may not reveal, particularly when adversaries practice good communications security.

Question 67: You are preparing to deploy a heuristic-based detection system to monitor network activity. Which of the following would you create first?

Alert Thresholds
Signature Database
Incident Response Plan
Baseline (Correct answer)

Correct answer: Baseline

Explanation: Baseline is the best description because before deploying a heuristic-based detection system to monitor network activity, you would create a baseline to establish a reference point for normal network behavior. This baseline helps the system identify deviations or anomalies that may indicate suspicious or malicious activity. By establishing a baseline, you can enhance the accuracy and effectiveness of the heuristic-based detection system in identifying potential threats.

Question 68: What is the 'need-to-know' principle in OPSEC?

A public disclosure policy for government operations
A training certification requirement for all cleared employees
A mandatory security violation reporting requirement
The principle that access to sensitive information is limited to those who genuinely require it for official duties (Correct answer)

Correct answer: The principle that access to sensitive information is limited to those who genuinely require it for official duties

The need-to-know principle limits access to sensitive information only to those who require it to perform official duties, reducing the risk of unauthorized or inadvertent disclosure.

Question 82: In the item below, try to visualize the shape that would complete the matrix, based on the pattern(s) of shapes.

F
E
C
D
B
A (Correct answer)

Correct answer: A

Explanation: The correct answer is A. The positioning of the small black square inside the large square corresponds with the position of the figure in the matrix: All the figures in the leftmost column have their black square on the left, the middle column in the middle, and the right column on the right. All the figures in the top row have their squares on top, the middle row in the middle, and the bottom row at the bottom. The bottom-right figure should, therefore, have its black square at the bottom-right corner.
