   A security analyst is reviewing a third-party vendor's cloud controls matrix (CCM) and notices that the 'Data Retention' control states 'Customer data is deleted within 30 days of contract termination.' The vendor's SOC 2 Type II report includes a control description for data deletion but the auditor noted that the testing was 'performed via inspection of the vendor's deletion procedure documentation, not by observing an actual deletion.' The analyst's organization requires verified deletion of data after contract termination. What is the most appropriate action?

   • AReject the vendor because the SOC 2 auditor did not observe an actual deletion, proving the vendor does not delete data.
   • BRely on the SOC 2 Type II report because it includes the deletion control, which is sufficient assurance.
   • CRequest a contractual clause that requires the vendor to provide a certificate of deletion after contract termination, and verify the deletion process through a test.
   • DAccept the CCM's 30-day deletion commitment because it is a documented policy.

   A development team is considering an open-source library for a new project. The library is widely used, has a strong reputation, and its latest version is 2 years old. The maintainer has not committed to the repository in 14 months, and the project's issue tracker shows several unaddressed security vulnerabilities. The team's security policy requires that all third-party components have an active support lifecycle. What should the team do?

   • AUse the library because its popularity and past reputation outweigh the lack of recent activity.
   • BUse the library and rely on runtime monitoring to detect any exploitation of the known vulnerabilities.
   • CUse the library but fork it internally to fix the vulnerabilities and maintain it in-house.
   • DReject the library and search for an actively maintained alternative with a responsive security process.

   A development team is selecting a third-party logging library. Vendor A is a well-known open-source project with a large community and regular releases. Vendor B is a commercial product with a smaller user base but offers a paid support contract with a 24-hour response SLA. The team's application is mission-critical and the team has limited in-house expertise in the library's language. Which factor is most important in this decision?

   • AVendor A's large community, because more users mean more security researchers are reviewing the code.
   • BVendor B's smaller user base, because it means the library is less likely to be a target for attackers.
   • CVendor A's regular releases, because frequent updates indicate active maintenance and security patching.
   • DVendor B's paid support contract, because the team's limited in-house expertise makes responsive vendor support critical.
