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 correct answer is D - Review.
WGU Cybersecurity Architecture and Engineering (KFO1 / D488) describes that the review phase of the risk management cycle involves evaluating whether the implemented controls are effective over time. Conducting regular risk assessments after deployment falls under the review process.
Control (A) is about applying mitigations. Assess (B) happens earlier during initial evaluation. Identify (C) was done before applying the controls.
Reference Extract from Study Guide:
"Reviewing the effectiveness of risk control strategies through ongoing assessments ensures continuous improvement in risk management practices."

The correct answer is D - Open Authorization (OAuth).
According to the WGU Cybersecurity Architecture and Engineering (KFO1 / D488) Study Guide, OAuth is the standard protocol used for authorizing access to third-party applications without revealing user credentials.
It allows users to log in using social identity providers like Google, Facebook, or LinkedIn, which is perfect for external customers and contractors accessing a mobile application. OAuth is designed for modern applications requiring delegated access.
SAML (A) is generally used for enterprise single sign-on (SSO) solutions, primarily for internal enterprise authentication, not social login. Kerberos (B) is used within controlled internal network environments for authentication. LDAP (C) is a directory access protocol, not an authorization protocol for third-party sign-in.
Reference Extract from Study Guide:
"OAuth enables users to grant a third-party application limited access to their resources withoutexposing their credentials, making it ideal for mobile and web applications involving external users."

Scope creep refers to the phenomenon where the scope of a project gradually increases over time due to small, incremental changes that were not initially planned or approved. This can happen when:
* New featuresor requirements are added without proper evaluation or approval.
* Stakeholderscontinuously request small changes or additions.
* Lack of a clear scope definitionand change control process.
These small changes can accumulate, leading to significant deviations from the original project plan, affecting the project's schedule, budget, and overall success.

Preventing unauthorized access and impersonation during exams or coursework is critical in e-learning platforms.Strong user authentication(e.g., MFA, CAPTCHA, secure login mechanisms) ensures that only authorized users access exams and coursework.
NIST SP 800-63B (Digital Identity Guidelines - Authentication):
"Secure user authentication ensures the identity of individuals accessing sensitive applications, reducing the risk of impersonation and credential misuse." Firewall rules and patching are important, but they don't directly addressuser-level fraud prevention.
