CCST Cybersecurity sample questions

Question 1

A company wants to reduce the chance that a stolen password alone can access email. Which control best fits?

• A. Multi-factor authentication
• B. Packet capture
• C. Disk defragmentation
• D. Public IP addressing

Best answer: A

Explanation: MFA strengthens authentication by requiring more than the password alone.

Question 2

A vulnerability scan reports a medium-severity issue on an internet-facing server, and threat intelligence shows active exploitation. What should the technician consider?

• A. Ignore it because medium findings are never urgent
• B. Prioritize it using exposure, exploit activity, and business impact
• C. Delete the scanner results
• D. Disable all logging

Best answer: B

Explanation: Risk priority depends on context, not score alone. Exposure and active exploitation increase urgency.

Question 3

Which statement best separates authentication from authorization?

• A. Authentication is routing; authorization is switching.
• B. Authentication proves identity; authorization determines allowed actions.
• C. Authentication encrypts files; authorization hashes passwords.
• D. Authentication is always physical; authorization is always wireless.

Best answer: B

Explanation: Authentication answers “who are you?” Authorization answers “what may you do?”

Question 4

An IDS generates an alert for traffic to a suspicious domain. What is the best first analyst habit?

• A. Treat the host as fully compromised without checking anything
• B. Validate and correlate the alert with host, DNS, proxy, and endpoint evidence
• C. Clear all logs to remove noise
• D. Disable the firewall permanently

Best answer: B

Explanation: An alert is a signal. Good triage validates the source, asset, timeline, and related evidence before choosing containment or escalation.

Question 5

A user asks a technician to share an administrative password in chat so a task can be completed faster. What is the safest response?

• A. Share the password but delete the message later
• B. Follow approved access and escalation procedures
• C. Put the password in the ticket for tracking
• D. Disable authentication temporarily

Best answer: B

Explanation: Secure support behavior avoids sharing secrets and follows approved access workflows.

Question 6

Which control most directly separates guest Wi-Fi users from internal systems?

• A. Network segmentation
• B. Screen resolution
• C. File compression
• D. Keyboard mapping

Best answer: A

Explanation: Segmentation separates traffic and reduces exposure between groups such as guests and internal systems.

Question 7

A laptop shows a malware alert with suspicious outbound connections. Which support action is usually safest?

• A. Isolate according to playbook, preserve evidence, and escalate
• B. Delete all logs immediately
• C. Send the user the admin password
• D. Ignore the alert because users need network access

Best answer: A

Explanation: Suspected malware requires controlled containment and evidence preservation, not convenience-driven bypasses.

Question 8

Which term describes reducing risk when the full fix cannot be applied immediately?

• A. Mitigation
• B. Authentication
• C. Hashing
• D. Throughput

Best answer: A

Explanation: Mitigation reduces risk temporarily or partially. Remediation fixes or removes the weakness.
