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

The correct answer is A — Virtual network peering.

According to the WGU Cybersecurity Architecture and Engineering (KFO1 / D488) Study Guide, virtual network peering enables direct communication between two or more virtual networks without the need for gateways, VPNs, or additional configurations. It allows seamless interconnectivity with minimal administrative overhead. Peered networks can communicate as if they were part of the same network, which meets the organization's request for the least administrative effort.

Other options like Virtual LANs (B) operate within the same network and don't span multiple virtual networks. Remote Desktop Protocol (C) is used for remote access, not network interconnection. Domain Name System (D) resolves names to IP addresses but does not establish communication pathways between networks.

Reference Extract from Study Guide:

"Virtual network peering provides a low-latency, high-bandwidth connection between virtual networks with minimal administrative setup. It is the recommended solution for direct communication across cloud-based virtual networks."

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

The correct answer is B — Mandatory vacation.

According to the WGU Cybersecurity Architecture and Engineering (KFO1 / D488) coursework, mandatory vacation policies require employees to take time off, during which their duties are either paused or performed by others. This break can reveal fraudulent activities, as the original employee cannot cover up their misconduct during their absence.

Separation of duties (A) prevents a single person from controlling critical processes but is not about temporarily removing an employee. Job rotation (C) moves employees between rolesregularly but doesn't enforce a break. Least privilege (D) restricts access but does not address uncovering hidden misconduct.

Reference Extract from Study Guide:

"Mandatory vacations help detect fraudulent activities, as employee absence can expose irregularities that would otherwise remain hidden through continuous control over processes."

The correct answer is D — Removing all end-of-life devices from the network.

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), end-of-life systems pose significant risks because they no longer receive patches or updates. The besthardening technique in this situation is to decommission and remove these devices, eliminating their vulnerabilities altogether.

Access control (A), vulnerability scanning (B), and IDPS (C) are helpful practices but do not eliminate vulnerabilities of unsupported devices.

Reference Extract from Study Guide:

"Removing end-of-life or unsupported assets is essential for maintaining a secure infrastructure, as these devices are highly vulnerable to exploitation."

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

Proxy Server Functions:

Caching: Proxy servers can store copies of web pages and other web resources. This helps to improve load times for frequently accessed resources and reduce bandwidth usage.

Security: They can provide additional security by anonymizing the user’s IP address and filtering unwanted content.

Correct Function:

Acting as a cache (B) is one of the primary functions, where it stores web pages that users in the organization have recently accessed.

Incorrect Functions:

A: Describes a file server.

C: Describes a database server.

D: Describes a web server.

The correct answer is A — Mandatory access control (MAC).

Per WGU Cybersecurity Architecture and Engineering (KFO1 / D488) coursework, MAC is a strict access control model where access to resources is based on information labels (such as classified, secret, top secret) and user clearances. Only administrators define and control the policy rules, and users cannot alter access settings, making it ideal for environments where classification labels determine access rights, such as government systems.

ABAC (B) focuses on attributes but is more dynamic rather than based purely on rigid classifications. DAC (C) gives data owners control over access permissions, unsuitable for classified government environments. RBAC (D) assigns permissions based on roles, but not necessarily aligned with security labels.

Reference Extract from Study Guide:

"Mandatory access control (MAC) enforces access policies based on fixed labels and security classifications, making it the preferred model for high-security environments like government agencies handling classified data."

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

The correct answer is A — Implementing two-factor authentication.

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488) content, two-factor authentication (2FA) strengthens authentication processes by requiring users to providetwo forms of evidence (e.g., password + SMS code or authentication app) before accessing systems. Even if credentials are stolen, without the second factor, attackers would be unable to log in.

Background checks (B) are important for insider threats but not stolen external credentials. Security awareness training (C) is good practice but does not technically prevent the misuse of stolen credentials. SIEM systems (D) help detect breaches but do not stop unauthorized access at the authentication layer.

Reference Extract from Study Guide:

"Two-factor authentication mitigates the risks associated with credential theft by requiring an additional factor, significantly improving the security posture."

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

The correct answer is D — Federated authentication.

WGU Cybersecurity Architecture and Engineering (KFO1 / D488) explains that federated authentication allows two or more organizations to share identity information securely withoutneeding to maintain separate user accounts for external users. It supports cross-organizational access based on trusted identity providers.

Cloud identity providers (A) offer centralized authentication but don't address federation directly. SSO (B) simplifies authentication within an organization. MFA (C) adds security but does not enable cross-organization authentication.

Reference Extract from Study Guide:

"Federated authentication enables organizations to share identity information and trust external credentials without the need to manage separate accounts for external users."

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

The correct answer is B — Business impact analysis (BIA).

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), a BIA identifies and prioritizes critical business functions and assesses the impact of disruptions on those functions. It determines recovery priorities and establishes the framework for disaster recovery and business continuity planning.

BCP (A) is the broader planning effort. DR (C) focuses on restoring systems. IR (D) responds to specific incidents, not overall business impacts.

Reference Extract from Study Guide:

"Business impact analysis (BIA) determines the criticality of business processes by assessing thepotential impacts of disruptions, providing the foundation for prioritizing recovery efforts."

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

The goal of an IT department that directly supports business goals is to develop technological solutions that enable and enhance the company's business operations. Developing an online shopping cart for company products directly supports the business goal of facilitating online sales. This involves:

E-commerce functionality: Enabling customers to browse, select, and purchase products online.

User experience: Creating a seamless and user-friendly shopping experience to drive sales.

Integration: Ensuring the shopping cart integrates with backend systems like inventory and order management.

This development aligns with business goals by enabling revenue generation through online sales.

The correct answer is C — Implementation of secure user authentication protocols.

WGU Cybersecurity Architecture and Engineering (KFO1 / D488) emphasizes that secure authentication mechanisms, like strong passwords, multifactor authentication, and session management, prevent unauthorized access and impersonation, thus helping prevent cheating inlearning platforms.

Firewall policies (A) and disabling Bluetooth (B) harden systems but do not directly address authentication. Software updates (D) protect against system vulnerabilities but not user integrity.

Reference Extract from Study Guide:

"Secure authentication protocols ensure that users accessing learning management systems are properly verified, reducing risks of impersonation and cheating."
