CERTIFICATION PREPARATION
1. A project team is preparing to deploy a new application to production. Which action should be
completed first to reduce deployment risk?
A. Notify customers after deployment
B. Create a rollback plan
C. Increase server capacity
D. Disable monitoring alerts
Correct Answer: B. Create a rollback plan
Rationale: A rollback plan provides a controlled recovery path if the deployment fails. While capacity
planning, notifications, and monitoring adjustments may be necessary, risk mitigation begins with
ensuring the organization can quickly restore service if problems occur.
2. Which principle is most closely associated with least privilege access?
A. Grant users only the permissions required to perform their duties
B. Allow administrators unrestricted access
C. Assign identical permissions to all users
D. Rotate passwords annually
Correct Answer: A. Grant users only the permissions required to perform their duties
Rationale: Least privilege limits access rights to the minimum necessary, reducing security exposure.
The other options either provide excessive access or address unrelated security controls.
3. A monitoring system reports high CPU utilization on a production server. What should an
engineer do first?
A. Rebuild the server
B. Add more storage
C. Investigate the processes consuming CPU resources
D. Restart all services
Correct Answer: C. Investigate the processes consuming CPU resources
Rationale: Effective troubleshooting begins with identifying the root cause. Immediately rebuilding or
restarting systems without analysis may worsen the situation or hide valuable diagnostic
information.
4. Which backup strategy provides the fastest recovery time in most environments?
A. Differential backups only
B. Incremental backups only
C. Monthly full backups
D. Regular full backups combined with incremental backups
,Correct Answer: D. Regular full backups combined with incremental backups
Rationale: Full backups simplify restoration while incremental backups reduce storage requirements.
This combination typically balances recovery speed and operational efficiency.
5. A company requires evidence that system changes were reviewed before implementation.
Which control best satisfies this requirement?
A. Asset inventory
B. Change approval workflow
C. Data encryption
D. Antivirus software
Correct Answer: B. Change approval workflow
Rationale: A formal change approval process documents review and authorization activities. The
other controls support different operational objectives.
6. What is the primary purpose of a disaster recovery plan?
A. Improve software development speed
B. Reduce hardware costs
C. Restore critical operations after a disruptive event
D. Eliminate all security risks
Correct Answer: C. Restore critical operations after a disruptive event
Rationale: Disaster recovery planning focuses on restoring essential business services following
outages, disasters, or significant disruptions.
7. During a security audit, an engineer discovers unused user accounts. What is the best course of
action?
A. Leave them unchanged
B. Archive logs only
C. Increase password complexity
D. Disable or remove the unused accounts
Correct Answer: D. Disable or remove the unused accounts
Rationale: Unused accounts present unnecessary risk and should be disabled or removed according to
organizational policy.
8. Which metric is most useful for measuring service availability?
A. Mean Time Between Failures (MTBF)
B. Storage capacity
C. Number of users
D. Programming language count
Correct Answer: A. Mean Time Between Failures (MTBF)
Rationale: MTBF helps measure reliability and availability. The other options do not directly quantify
service uptime.
9. A team is implementing infrastructure as code. What is a key benefit?
A. Eliminates documentation needs
B. Enables consistent and repeatable deployments
, C. Removes all security requirements
D. Guarantees zero downtime
Correct Answer: B. Enables consistent and repeatable deployments
Rationale: Infrastructure as code promotes standardization, version control, and repeatability across
environments.
10. Which action best protects sensitive data in transit?
A. Compression
B. Deduplication
C. Encryption
D. Defragmentation
Correct Answer: C. Encryption
Rationale: Encryption protects data confidentiality while it moves across networks. The other options
address performance or storage concerns.
11. A critical system experiences intermittent outages. What should be documented after
resolution?
A. Marketing strategy
B. Budget forecast
C. Incident postmortem
D. Office seating plan
Correct Answer: C. Incident postmortem
Rationale: A postmortem captures lessons learned, root causes, and improvement actions to reduce
future incidents.
12. What is the main objective of capacity planning?
A. Predict and meet future resource requirements
B. Reduce audit frequency
C. Eliminate backups
D. Restrict user access
Correct Answer: A. Predict and meet future resource requirements
Rationale: Capacity planning ensures resources can support future business and technical demands.
13. Which network device primarily forwards traffic based on IP addresses?
A. Hub
B. Router
C. Repeater
D. Patch panel
Correct Answer: B. Router
Rationale: Routers make forwarding decisions using network-layer addressing information.
14. An organization stores customer information subject to regulatory requirements. Which
practice is most important?
A. Ignoring retention policies
