Source-backed answer review

The free daily Cisco CCST Cybersecurity set includes crawlable question text, answer choices, correct answer labels, objective mapping, and source links. Only the first SEO card includes answer explanations and any extra learning features. Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.

Question 1 The primary data center loses power for two days. An alternate site exists, but no one has tested network routes, credentials, or application dependencies there. What is the MOST important lesson?

Answer choices

  1. A. Owning an alternate site automatically satisfies all recovery objectives.
  2. B. Only hardware availability matters during disaster recovery.
  3. C. Credentials should be created for the first time during the outage.
  4. D. Alternate-site capability must be exercised end to end

Correct answer

Alternate-site capability must be exercised end to end

Continuity plans need testing of people, procedures, connectivity, dependencies, and restoration, not just alternate hardware.

Wrong-answer review

  • A. Owning an alternate site automatically satisfies all recovery objectives.: This is a plausible control in another context, but not for the evidence given here. Continuity plans need testing of people, procedures, connectivity, dependencies, and restoration, not just alternate hardware.
  • B. Only hardware availability matters during disaster recovery.: This focuses on availability while leaving the security condition unresolved. Continuity plans need testing of people, procedures, connectivity, dependencies, and restoration, not just alternate hardware.
  • C. Credentials should be created for the first time during the outage.: This would act on the symptom without addressing the relevant control. Continuity plans need testing of people, procedures, connectivity, dependencies, and restoration, not just alternate hardware.

Extra learning features

Why candidates miss this

The distractor ‘Only hardware availability matters during disaster recovery’ is tempting because it focuses on a tangible component. However, the core issue is the lack of comprehensive testing, encompassing people, procedures, and connectivity. The decisive clue is the explicit mention of testing network routes, credentials, and application dependencies, highlighting the need for a holistic approach. Likely wrong answer: Only hardware availability matters during disaster recovery. Review focus: NIST SP 800-34 Rev. 1 — Contingency Planning Guide for Federal Information Systems

Question 2 A payroll database remains online, but an unauthorized administrator changes employee bank-account numbers while legitimate users can still access the application. Which security objective has been compromised MOST directly?

Answer choices

  1. A. Integrity, because the information was modified without authorization.
  2. B. Availability, because authorized users can still reach the database.
  3. C. Confidentiality, because the data exists in a sensitive system.
  4. D. Nonrepudiation, because the administrator used a privileged account.

Correct answer

Integrity, because the information was modified without authorization.

Question 3 A configuration scanner reports that a server differs from the approved baseline on 40 settings. Ten differences are documented exceptions with active approvals. What is the BEST next step?

Answer choices

  1. A. Treat all 40 differences as incidents without checking approved exceptions.
  2. B. Ignore all differences because at least one exception exists.
  3. C. Replace the baseline with the current server configuration automatically.
  4. D. Validate the approved exceptions and investigate/remediate the remaining unexplained drift.

Correct answer

Validate the approved exceptions and investigate/remediate the remaining unexplained drift.

Question 4 A malware-infected workstation is isolated, but the stolen user credential remains valid and is being used from another device. What is the BEST next containment action?

Answer choices

  1. A. Contain the identity compromise as well—disable/reset or otherwise secure the credential/session according to policy while continuing investigation.
  2. B. Reconnect the workstation because host isolation already completed containment.
  3. C. Ignore identity activity because containment applies only to devices.
  4. D. Restore the workstation and leave the credential unchanged.

Correct answer

Contain the identity compromise as well—disable/reset or otherwise secure the credential/session according to policy while continuing investigation.

Question 5 A vulnerability management policy says 'patch critical findings in 30 days' but does not account for active exploitation or internet exposure. What is the BEST improvement?

Answer choices

  1. A. Allow risk-based acceleration when exploitation, exposure, asset criticality, or business impact warrants faster action.
  2. B. Use the same deadline for every vulnerability to guarantee fairness.
  3. C. Base deadlines only on how old the hardware is.
  4. D. Delay all patches until the vendor publishes a second advisory.

Correct answer

Allow risk-based acceleration when exploitation, exposure, asset criticality, or business impact warrants faster action.

Question 6 A web application verifies a user’s password successfully, then checks whether the user can open the payroll report. What are these two operations, in order?

Answer choices

  1. A. Authorization first, followed by authentication.
  2. B. Authentication first, followed by authorization.
  3. C. Accounting first, followed by encryption.
  4. D. Identification first, followed by availability.

Correct answer

Authentication first, followed by authorization.

Question 7 A vulnerability scanner still reports the same CVE after a patch deployment that completed with no errors. Which action is MOST important?

Answer choices

  1. A. Close the finding because the deployment tool reported success.
  2. B. Suppress the scanner permanently.
  3. C. Uninstall logging so the scanner cannot detect the host.
  4. D. Verify the actual software/firmware version and rescan or otherwise confirm the vulnerability is remediated.

Correct answer

Verify the actual software/firmware version and rescan or otherwise confirm the vulnerability is remediated.

Question 8 An incident may involve regulated customer information, but the technical team does not yet know whether data actually left the environment. Which response BEST accounts for compliance without making unsupported claims?

Answer choices

  1. A. Preserve evidence, involve the organization’s legal/privacy/compliance process, determine the affected data and scope, and track any applicable notification obligations.
  2. B. Announce a confirmed reportable breach immediately without validating scope.
  3. C. Delete the affected logs to minimize stored personal information.
  4. D. Assume no obligation exists until an attacker admits exfiltration.

Correct answer

Preserve evidence, involve the organization’s legal/privacy/compliance process, determine the affected data and scope, and track any applicable notification obligations.

Question 9 Firewall logs show return traffic being dropped even though the client initiated an allowed outbound TCP session. Which firewall capability would MOST directly simplify allowing legitimate return traffic while still blocking unsolicited inbound sessions?

Answer choices

  1. A. A stateless rule that permits every inbound high-numbered port.
  2. B. Disabling the firewall during client sessions.
  3. C. A hub that copies all frames to every port.
  4. D. Stateful inspection that tracks established connection state.

Correct answer

Stateful inspection that tracks established connection state.

Question 10 A firewall rule permits management access to 10.20.30.0/24, but the jump server is actually 10.20.31.15/24. What is the MOST important consequence?

Answer choices

  1. A. The rule does not include the jump server’s subnet
  2. B. The jump server automatically becomes public because its third octet differs.
  3. C. The firewall will translate the server into 10.20.30.15 without a NAT rule.
  4. D. The /24 mask allows both 10.20.30.0 and 10.20.31.0 by default.

Correct answer

The rule does not include the jump server’s subnet
