A network administrator needs to apply a firmware update to several enterprise network switches following standard operational procedures. In which sequential order should the administrator perform the steps of the patch management lifecycle?
- 1Identify the required patch and download it from the official vendor portal.
- 2Validate and test the patch in an isolated non-production lab environment.
- 3Submit a formal change request and obtain maintenance window authorization.
- 4Deploy the patch to production network devices during the approved window.
- 5Perform post-deployment auditing and monitor system logs for anomalies.
Answer
The correct sequence for the patch management lifecycle is: 1) Identify and download the patch from the official vendor portal, 2) Validate and test the patch in an isolated lab environment, 3) Submit a formal change request and obtain maintenance window authorization, 4) Deploy the patch to production network devices during the approved window, and 5) Perform post-deployment auditing and monitor system logs for anomalies.
The correct order follows the established patch management process: Acquisition -> Lab Testing -> Change Management Approval -> Production Deployment -> Post-deployment Audit.
