A systems administrator has just implemented a new feature into the company's web application. The following week, a patch is released for the software version that was used to develop the feature. What should the systems administrator do to ensure both the new feature and the software remain up to date with minimal risk to service stability?
Perform regression testing on the new feature with the patched software version before deploying.
Roll back the new feature to prioritize the patch update.
Immediately deploy the patched software version company-wide.
Ignore the patch and focus on feature development to avoid compatibility issues.
Develop a separate instance with the patch and the new feature to conduct user acceptance testing.
Wait for the next major software release to include the new feature and the patch update.
The correct answer is to perform regression testing on the new feature with the patched software version before deploying. Regression testing is crucial for verifying that new updates do not disrupt existing functionality. It ensures compatibility between the new feature and the updated software, mitigating the risk to existing services. Skipping regression testing risks introducing errors that can affect system stability or functionality.
