CompTIA CV0-004 Practice Test 43
Question 420
The infrastructure architect at a regional health provider investigates this condition: an infrastructure team patches a low-risk library ahead of a remotely exploited internet-facing service solely because its CVSS is slightly higher. Which explanation best accounts for it?
- A scan result is only evidence for its configured scope and cannot prove omitted assets are safe.
- Ephemeral cloud resources need discovery aligned to their life cycle rather than infrequent manual lists.
- Risk acceptance is a governance decision, not proof that a vulnerable asset has become secure.
- A vulnerability score is useful but does not by itself capture local reachability or active exploitation.
Explanation
Correct Answer
D:The evidence of success is: The actively exposed service is mitigated first and remaining risk decisions are documented.
Incorrect Answers
A:That approach would help when a security scanner never examines private container registries and the team incorrectly concludes the cloud estate has no vulnerable images. Check the difference through: Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
B:The alternative is aimed at a different condition: Cloud teams create short-lived servers faster than nightly vulnerability scans run, leaving unidentified unpatched instances. It does not directly resolve the described failure. A vulnerability score is useful but does not by itself capture local reachability or active exploitation. Check the difference through: Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
C:The proposed measure serves a related cloud task, but the present symptom calls for a more specific response. A vulnerability score is useful but does not by itself capture local reachability or active exploitation. Check the difference through: Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
Question 421
At a global distribution company, an engineer needs to close a case where an infrastructure team patches a low-risk library ahead of a remotely exploited internet-facing service solely because its CVSS is slightly higher. What test is most decisive?
- The actively exposed service is mitigated first and remaining risk decisions are documented.
- The exception expires or is renewed with evidence and the exposed service has enforced interim restrictions.
- Each newly launched test instance appears in the asset register and receives vulnerability assessment.
- Test vulnerable images in each intended registry appear in reports without scanning unauthorized assets.
Explanation
Correct Answer
A:The actively exposed service is mitigated first and remaining risk decisions are documented. This proves the service behavior rather than just showing a changed configuration. A vulnerability score is useful but does not by itself capture local reachability or active exploitation.
Incorrect Answers
B:That approach would help when a mission-critical service cannot immediately install a required vendor fix because the patch breaks a licensed plugin. The required acceptance result is: The actively exposed service is mitigated first and remaining risk decisions are documented.
C:A vulnerability score is useful but does not by itself capture local reachability or active exploitation. The required acceptance result is: The actively exposed service is mitigated first and remaining risk decisions are documented.
D:A vulnerability score is useful but does not by itself capture local reachability or active exploitation. The proposed measure serves a related cloud task, but the present symptom calls for a more specific response.
Question 422
At a regional health provider, this issue is reported: an infrastructure team patches a low-risk library ahead of a remotely exploited internet-facing service solely because its CVSS is slightly higher. What should be examined before applying a fix?
- Compare asset inventory, scan credentials, coverage exclusions and scan schedules.
- Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
- Review owner, compensating controls, fix timetable and exception approvals.
- Compare source Dockerfile, package SBOM, registry digest and deployed image.
Explanation
Correct Answer
B:Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality. This distinguishes the relevant dependency before changing cloud resources. A vulnerability score is useful but does not by itself capture local reachability or active exploitation.
Incorrect Answers
A:That approach would help when a security scanner never examines private container registries and the team incorrectly concludes the cloud estate has no vulnerable images. Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
C:Review owner, compensating controls, fix timetable and exception approvals. The relevant cloud response here is: Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
D:Compare source Dockerfile, package SBOM, registry digest and deployed image. The relevant cloud response here is: Review CVE evidence, exploit intelligence, reachable attack paths and asset criticality.
Question 423
At a global distribution company, an operational review finds that an approved application image contains a vulnerable base package but its pipeline keeps rebuilding the same unchanged base image. What is the best next step?
- Prioritize remediation using exploit activity, exposure and business impact alongside published severity.
- Document a time-bound exception with compensating controls and a tested fix plan.
- Update the base image dependency, rebuild and scan the resulting immutable artifact.
- Integrate resource inventory events with vulnerability assessment and short-lived asset reporting.
Explanation
Correct Answer
C:Container remediation must affect the image shipped to production, not only a host package inventory. The change should be verified, not just applied: The deployed digest contains the fixed package and vulnerability scans no longer flag the finding.
Incorrect Answers
A:That approach would help when an infrastructure team patches a low-risk library ahead of a remotely exploited internet-facing service solely because its CVSS is slightly higher. In this case, container remediation must affect the image shipped to production, not only a host package inventory.
B:Risk acceptance is a governance decision, not proof that a vulnerable asset has become secure. The relevant cloud response here is: Update the base image dependency, rebuild and scan the resulting immutable artifact.
D:Ephemeral cloud resources need discovery aligned to their life cycle rather than infrequent manual lists. The relevant cloud response here is: Update the base image dependency, rebuild and scan the resulting immutable artifact.
