WGU D115 OA Prep: Questions
Multiple-Choice Questions (1–150)
1. Which of the following is the primary purpose of a business continuity plan (BCP)?
A. To eliminate all IT risks
B. To provide a framework for restoring operations after a disruption
C. To ensure maximum profitability
D. To replace disaster recovery plans
Answer: B
Rationale: A BCP is designed to maintain business operations during and after a disruptive event. It
complements, but does not replace, disaster recovery plans and does not aim to eliminate all risk.
2. A company wants to implement a centralized data repository to improve decision-making. Which
approach is most appropriate?
A. Data warehouse
B. Data mart
C. Transactional database
D. Cloud storage only
Answer: A
Rationale: A data warehouse consolidates data from multiple sources for reporting and analysis. Data
marts are smaller subsets, transactional databases support operations, and cloud storage alone does not
ensure integration or analytics capabilities.
,3. In IT project management, what is the main purpose of the Critical Path Method (CPM)?
A. To identify tasks that can be delayed without impacting the project
B. To calculate total project cost
C. To determine the sequence of tasks that directly impacts project duration
D. To assign project roles and responsibilities
Answer: C
Rationale: CPM identifies the longest sequence of dependent tasks that determines the minimum
project duration. Tasks not on the critical path may have float (slack).
4. Which of the following best describes normalization in database design?
A. Storing all data in one large table
B. Splitting data into related tables to reduce redundancy
C. Backing up the database regularly
D. Converting relational data to NoSQL
Answer: B
Rationale: Normalization organizes data into tables to reduce redundancy and ensure data integrity. It
does not involve backups or NoSQL conversion.
5. A company is experiencing frequent data breaches. Which security control is most effective to
protect sensitive data?
A. Firewall
B. Encryption
C. Password complexity rules
D. Employee email training
Answer: B
Rationale: Encryption ensures data is unreadable if accessed by unauthorized users. Firewalls,
passwords, and training help but do not fully protect the data itself.
6. What is the main difference between a risk assessment and a vulnerability assessment?
A. Risk assessment identifies threats and their impact; vulnerability assessment identifies weaknesses in
systems
B. Risk assessment is only qualitative; vulnerability assessment is only quantitative
C. They are the same process
D. Risk assessment is done annually; vulnerability assessment is done weekly
Answer: A
Rationale: A risk assessment evaluates potential threats and impact, while a vulnerability assessment
identifies weaknesses that could be exploited.
,7. Which project management methodology is most iterative and adaptive to changing requirements?
A. Waterfall
B. Agile
C. Six Sigma
D. PRINCE2
Answer: B
Rationale: Agile is iterative and flexible, accommodating changing requirements, whereas Waterfall is
linear, Six Sigma focuses on process improvement, and PRINCE2 is a structured methodology.
8. A company implements role-based access control (RBAC). Which of the following is a benefit?
A. Users can access any system they choose
B. Access is granted based on job roles, reducing security risks
C. Passwords are no longer required
D. Encryption is no longer necessary
Answer: B
Rationale: RBAC ensures that employees only access systems needed for their job, minimizing security
exposure.
9. Which type of cloud service model provides the customer with operating systems, storage, and
deployed applications without managing the underlying infrastructure?
A. IaaS
B. PaaS
C. SaaS
D. DaaS
Answer: C
Rationale: SaaS (Software as a Service) delivers fully managed applications; IaaS provides infrastructure,
PaaS provides development platforms, DaaS provides virtual desktops.
10. Which of the following is a key advantage of using a relational database over a flat-file database?
A. Faster network speed
B. Data integrity and the ability to define relationships between tables
C. Eliminates need for backup
D. Requires no SQL knowledge
Answer: B
Rationale: Relational databases maintain data integrity, enforce relationships, and reduce redundancy,
unlike flat-file databases.
