Cybersecurity-Architecture-and-Engineering Exam Dumps - WGU Courses and Certificates Questions and Answers

The correct answer is D — Likelihood.

WGU Cybersecurity Architecture and Engineering (KFO1 / D488) emphasizes that when evaluating the chance of future incidents, the focus should be on likelihood — the probability that a threat will exploit a vulnerability again. Given that a breach has already occurred, it is important to assess how likely another breach could happen without additional security measures.

Impact (A) measures consequences, not probability. Risk (B) is a combination of impact and likelihood, but to specifically focus on future potential, likelihood (D) is primary. Threat actors (C) describe adversaries, not probabilities.

Reference Extract from Study Guide:

"Likelihood refers to the probability that a specific threat will successfully exploit a vulnerability, and is a key consideration in predicting future incidents."

=============================================

The employee needs to execute a program from the command line, which requires inputting commands into the computer.

The primary device for inputting commands is the keyboard.

Other options like the hard drive, speaker, and printer are not used for inputting commands.

The hard drive is used for data storage.

The speaker outputs sound.

The printer outputs documents.

Therefore, the correct peripheral device for this task is the keyboard.

The correct answer is B — Elliptic Curve Diffie-Hellman (ECDH).

WGU Cybersecurity Architecture and Engineering (KFO1 / D488) material highlights that ECDH is an enhanced, more efficient form of the traditional Diffie-Hellman key exchange, using elliptic curve cryptography (ECC). It provides similar security with much smaller key sizes, improving performance and efficiency.

DH (A) is the traditional method but is less efficient. RSA (C) is primarily used for encryption and digital signatures. DSA (D) is used for digital signatures, not for key exchange.

Reference Extract from Study Guide:

"Elliptic Curve Diffie-Hellman (ECDH) enhances traditional key exchange by utilizing elliptic curve cryptography, offering higher security with smaller key sizes and improved efficiency."

The SQL statementSELECT * FROM Customers WHERE State = 'Arizona';is used to select records from theCustomerstable.

TheSELECT *clause indicates that all columns from theCustomerstable should be returned.

TheWHEREclause filters the rows to only include those where theStatecolumn value is'Arizona'.

The result is a subset of theCustomerstable with all rows that match the condition.

Information Technology (IT) has revolutionized the way businesses operate, enabling them to reach global markets and audiences. IT facilitates communication, data exchange, and operational efficiency across borders, allowing companies to manage global operations and engage with international customers seamlessly. This global reach is a critical aspect of modern business strategies, driven by advancements in IT infrastructure and services.

An algorithm is a defined set of step-by-step procedures or a set of rules to be followed to perform a specific task or solve a problem. Here are the characteristics that describe an algorithm:

Unambiguous rules: Each step of an algorithm must be clearly defined and unambiguous. There should be no confusion in interpreting the instructions.

Definiteness: The algorithm should have a clear starting and stopping point, leading to a precise output after a finite number of steps.

Finiteness: Algorithms must terminate after a finite number of steps. They cannot run indefinitely.

Input and Output: An algorithm should take zero or more inputs and produce at least one output.

Therefore, the correct answer is "Unambiguous rules," as it directly reflects the essential characteristic of an algorithm being precise and clear in its steps.

Computer networks provide several benefits for businesses, including:

Lower IT operations costs: Networking allows businesses to share resources, such as printers and storage, reducing the need for individual equipment for each user and lowering overall IT costs.

Increased business efficiency: Networks enable faster communication and data sharing between employees, departments, and locations, leading to more efficient business operations and improved collaboration.

The characteristic of quality data represented here is relevance. When an organization sends customers email messages based on their purchase patterns, it ensures that the information is relevant to the customers' interests and needs. Relevant data is tailored to the specific context in which it is used, enhancing its value and effectiveness.

The correct answer is D — Establish a baseline for normal activity.

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488) materials, the first step in threat hunting is to understand what constitutes normal behavior within the environment. Establishing a baseline allows analysts to detect anomalies and deviations that could indicate malicious activity. Without a clear understanding of normal operations, it is extremely difficult to identify potential threats.

Deploying anti-malware solutions (A) and implementing intrusion detection systems (B) are important security measures but are not the first step in proactive threat hunting. Forming an incident response team (C) is essential for handling incidents but does not directly initiate threat hunting.

Reference Extract from Study Guide:

"Threat hunting begins with establishing a baseline of normal network, system, and user activity, enabling the detection of anomalies that may indicate potential threats."

=============================================

Next-Generation Firewalls (NGFWs)offer a unified solution that includes traditional packet filtering andadvanced detection featureslike Intrusion Detection and Prevention (IDPS). This makes them the most efficient and scalable option for replacing legacy firewalls in modern environments.

NIST SP 800-94 Rev. 1 (Guide to Intrusion Detection and Prevention Systems):

“NGFWs integrate IDS/IPS features with traffic inspection, enabling detection and prevention of attacks in real time.”
