Question 260
A medical software company patches running VMs manually but new autoscaled instances recreate outdated vulnerable images. Which limitation must be considered before claiming the issue is fully resolved?
Explanation
Correct Answer
Patching an existing VM does not repair the template used for new instances. This caution prevents extrapolating beyond the specific evidence or product boundary. Immutable infrastructure requires fixing the source artifact, not only one replica. The unresolved point should be tested using template version, new VM package inventory and patch compliance evidence rather than assuming a working interface proves full compliance or resilience.
Incorrect Answers
A successful patch run automatically modifies immutable instance templates. This limitation is framed as a blanket exception, but the case requires a different, narrower caution. The relevant boundary is that patching an existing VM does not repair the template used for new instances. Immutable infrastructure requires fixing the source artifact, not only one replica. Inspect template version, new VM package inventory and patch compliance evidence.
A template reference is always updated whenever a live VM gets patched. The proposed claim mistakes an incomplete signal or product feature for a universal guarantee. The relevant boundary is that patching an existing VM does not repair the template used for new instances. Immutable infrastructure requires fixing the source artifact, not only one replica. Inspect template version, new VM package inventory and patch compliance evidence.
Infrastructure templates are automatically repaired when security scanners report vulnerabilities. This claim exceeds the evidence and ignores an important risk or operational dependency. The relevant boundary is that patching an existing VM does not repair the template used for new instances. Immutable infrastructure requires fixing the source artifact, not only one replica. Inspect template version, new VM package inventory and patch compliance evidence.
