The error message reveals sensitive details (hostnames, database names, table names), constitutinginformation disclosure. This aids attackers in reconnaissance. Mitigation involves modifying the application to display generic error messages (e.g., “An error occurred”) instead of specifics.

Option A:Unsecure references suggest coding flaws, but this is a configuration/output issue, not input sanitization.

Option B:Unsecure protocols and HttpOnly cookies relate to session security, not error handling.

Option C:Correct—information disclosure is the issue; generic errors mitigate it.

Option D:No evidence of SQL injection (e.g., manipulated input); upgrading the database doesn’t address disclosure.

Unauthorized code changesand lack ofindependent verificationare directly mitigated bycode signing, which ensures that code is from a trusted source and has not been altered.

While digital signatures are part of code signing, the broader practice of code signing encompasses signature management, version integrity, and trusted sources.

Lightweight cryptography is irrelevant in this context; it's more about efficiency in constrained devices.

Non-repudiation is a benefit of digital signatures but doesn't directly solve the verification/integrity concerns alone.

FromCAS-005 Guide, Domain 4: Security Architecture, Tools, and Technologies:

“Code signing ensures that the code has not been tampered with and originates from a trusted developer.”

The question states that security scanning and quality assurance (QA) in the CI/CD pipeline have been completed with no issues, indicating that the code in the test branch is ready for production. According to the CompTIA SecurityX CAS-005 study guide (Domain 2: Security Operations, 2.3), in a secure CI/CD pipeline, once code passes automated security scans, QA, and other checks (e.g., unit testing, peer reviews), the next step is to merge the tested branch into the main branch for deployment to production.

Option B:Threat modeling is typically performed earlier, during design or development, not after passing CI/CD checks.

Option C:Unit testing is part of the CI/CD pipeline and should already be completed.

Option D:Peer reviews are conducted before or during the test phase, not after QAand security scans are clear.

Option A:Merging the test branch to the main branch is the logical next step to prepare for production deployment.

Vendor lock-in occurs when a client is overly dependent on a vendor, limiting flexibility. Risks include:

Option B:Vendors changing offerings (e.g., features, pricing) can disrupt the client, a key lock-in risk.

Option D:Decreased quality of service may result from reliance on a single vendor without alternatives.

Option A:Seamless data movement is a benefit, not a risk.

Option C:Sufficient service is neutral or positive, not a risk.

Option E:Multicloud is hindered by lock-in, not a risk of it.

Option F:Increased interoperability contradicts lock-in’s limitations.
