Answers
Course: WGU D635
Total Questions: 70 Unique Multiple-Choice Questions
Format: Multiple Choice (A-D) with Correct Answers and Explanations Highlighted in Green.
Section 1: Core Fundamentals & Theoretical Foundations (Questions 1–15)
1. Which primary objective distinguishes foundational operational practice from
standard tactical execution?
● A) Short-term cost reduction at the expense of infrastructure stability
● B) Alignment of long-term architectural goals with repeatable governance standards
● C) Immediate elimination of all manual verification protocols
● D) Delegation of all decision-making authority to lower-tier vendors
Correct Answer: B) Alignment of long-term architectural goals with repeatable
governance standards
Explanation: Strategic governance ensures that operational practices scale effectively and
maintain structural integrity, whereas simple tactical execution focuses only on localized, short-
term outcomes.
2. What is the main structural outcome of applying modular architecture in systemic
design?
● A) High tight coupling between independent processing components
● B) Increased operational risk due to single points of dependency
● C) Lower coupling and higher cohesion, allowing independent upgrades and
troubleshooting
● D) Elimination of the need for structured logging and audit controls
Correct Answer: C) Lower coupling and higher cohesion, allowing independent
upgrades and troubleshooting
Explanation: Modular design separates concerns so that individual subsystems can be updated,
maintained, or isolated without causing cascading failures across the overall system.
,3. In quantitative evaluation, how is systemic efficiency primarily calculated?
● A) Total input volume divided by overhead expenditure
● B) Ratio of useful work output to total resource energy/input expended
● C) Time taken to initiate a process without measuring output quality
● D) Maximum hardware capacity minus minimum expected workload
Correct Answer: B) Ratio of useful work output to total resource energy/input
expended
Explanation: System efficiency measures effective throughput relative to input consumption,
ensuring resources are utilized effectively.
4. What is the fundamental principle behind root cause analysis (RCA)?
● A) Assigning immediate individual fault during incident triage
● B) Identifying and resolving the core underlying defect rather than treating surface
symptoms
● C) Creating workaround documentation without modifying baseline configurations
● D) Escalating all anomalies directly to executive management
Correct Answer: B) Identifying and resolving the core underlying defect rather
than treating surface symptoms
Explanation: RCA aims to uncover systemic weaknesses that caused an event, preventing
recurrence rather than repeatedly addressing symptoms.
5. Which control type is designed to restore an system back to its normal operating
state after a security breach or operational failure?
● A) Preventive control
● B) Deterrent control
● C) Corrective control
● D) Detective control
Correct Answer: C) Corrective control
Explanation: Corrective controls act after an incident occurs to mitigate impact, repair damage,
and restore systems to baseline operations.
6. When assessing risk magnitude, which two primary variables are multiplied
together?
● A) Vulnerability count and asset value
● B) Likelihood (probability) of occurrence and Impact (severity)
● C) Threat count and mitigation budget
● D) Exposure time and system throughput
, Correct Answer: B) Likelihood (probability) of occurrence and Impact (severity)
Explanation: Standard quantitative risk assessment defines Risk = Likelihood x Impact,
balancing frequency against consequence.
7. What is the principal function of a baseline configuration in systems
management?
● A) Serving as an unchangeable historical artifact with no active monitoring purpose
● B) Providing an agreed-upon standard state against which changes can be measured
and audited
● C) Bypassing regular compliance testing during peak operational hours
● D) Ensuring maximum disk utilization across all cluster nodes
Correct Answer: B) Providing an agreed-upon standard state against which
changes can be measured and audited
Explanation: Baselines establish a known, tested configuration that enables teams to detect
drift, unauthorized alterations, or security misconfigurations.
8. Which methodology emphasizes iterative development, continuous feedback, and
small increment delivery?
● A) Waterfall model
● B) Agile methodology
● C) Big Bang model
● D) Rigid Sequential model
Correct Answer: B) Agile methodology
Explanation: Agile focuses on adaptive planning, evolutionary development, early delivery, and
continual improvement through small iterative cycles.
9. In risk management, what does "risk acceptance" mean?
● A) Purchasing an insurance policy to offset financial loss
● B) Implementing controls to reduce probability to zero
● C) Acknowledging the residual risk without taking additional active mitigation measures
● D) Transferring liability to a third-party service provider
Correct Answer: C) Acknowledging the residual risk without taking additional
active mitigation measures
Explanation: Risk acceptance occurs when the organization determines that the cost of
mitigating a risk outweighs the potential impact.
