Note: Premium Questions for Cybersecurity Architecture and Engineering (D488) were last updated On Oct. 12, 2026 (see below)
A company is developing a new system to process personal information about its customers, including their names, addresses, and purchase histories.
Which term describes the process of identifying and evaluating the potential effects that the new system may have on the privacy of personal information and developing strategies to mitigate those risks?
The correct answer is C --- Data Protection Impact Assessment (DPIA).
According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), a DPIA is conducted to assess how personal data is collected, stored, and processed, evaluating potential privacy impacts and defining measures to mitigate risks. This is essential for compliance with privacy laws and regulations, especially in systems handling sensitive customer information.
DR (A) and BCP (B) are about operational recovery, not data privacy. Risk management (D) is broader and not focused solely on privacy impact.
Reference Extract from Study Guide:
'A Data Protection Impact Assessment (DPIA) evaluates the effects of processing activities on the privacy of individuals and develops strategies to mitigate privacy risks.'

=============================================
A project manager is working on a project that involves securing the network of a tall building. The manager is tasked with managing these risks effectively to ensure the successful completion of the project within a given time frame and budget. The manager identified multiple potential risks associated with the project.
What is the next step in the risk management life cycle?
The correct answer is C --- Assess.
As per WGU Cybersecurity Architecture and Engineering (KFO1 / D488) materials, after risks have been identified, the next step in the risk management life cycle is to assess them. Assessment involves analyzing and prioritizing the risks based on their potential impact and likelihood. Only after assessment can proper strategies be formulated for controlling and mitigating the risks.
Identification (A) occurs before assessment, while reviewing (B) and controlling (D) happen later in the process.
Reference Extract from Study Guide:
'Following the identification of risks, the risk management process proceeds to risk assessment, where risks are analyzed and prioritized based on likelihood and impact to guide mitigation efforts.'

=============================================
An organization wants to ensure that its website is free of certain vulnerabilities before the final handoff to the client. What testing method should the organization use to inspect traffic and detect potential issues?
Abastion scanneris a tool or hardened system that inspects network traffic and identifies security vulnerabilities, particularly those visible from an external (internet-facing) viewpoint. It plays a key role inpost-development assessment.
OWASP Testing Guide v4.2:
'Use bastion hosts or hardened scanners to perform vulnerability assessments from an attacker's perspective.'
This option is preferable for final validation before system release, especially when looking for exposure from the public internet.
WGU Course Alignment:
Domain:System Security Engineering
Topic:Evaluate hardened systems and scanning tools during release validation
A company is concerned about the potential risks associated with unauthorized modifications to the Basic Input/Output System (BIOS) firmware on its servers. The company has decided to implement hardening techniques and endpoint security controls to mitigate the risk.
Which technique will prevent unauthorized modifications to the BIOS firmware on a server?
BIOS protectioninvolves enabling hardware security features such asfirmware password protection,secure boot, andwrite protection, which prevent unauthorized firmware modifications.
NIST SP 800-147 (BIOS Protection Guidelines):
''Proper BIOS protection mechanisms, including authenticated updates and access control, are critical to maintaining the integrity of the platform's startup environment.''
This is apreventive control. BIOS monitoring is reactive; backups protect data, not firmware integrity.
WGU Course Alignment:
Domain:System Security Engineering
Topic:Apply firmware and BIOS security controls to prevent low-level tampering
A company wants to ensure that the integrity of its systems is maintained during the startup process.
Which security technology can ensure the integrity of the system during startup by verifying that the system has not been compromised?
The correct answer is D --- Measured boot.
WGU Cybersecurity Architecture and Engineering (KFO1 / D488) explains that Measured Boot, often implemented with Trusted Platform Modules (TPMs), ensures that each component of theboot process is verified for integrity. It provides cryptographic evidence that the system's startup sequence has not been tampered with.
Two-factor authentication (A) secures user logins but does not verify boot integrity. IDS (B) monitors network or host behavior but does not protect the boot process. HSM (C) secures cryptographic operations, not the system boot.
Reference Extract from Study Guide:
'Measured Boot verifies the integrity of the boot process, providing assurance that the system has not been compromised during startup.'
