Difficulty: EasyPatch Management and Software Maintenance

A network administrator is establishing a standard patch management procedure for enterprise routers. Place the following steps of the software patch management lifecycle in the correct order from first to last.

  1. 1Identify and evaluate vendor patch releases for security vulnerabilities.
  2. 2Test the software patch in an isolated lab environment.
  3. 3Submit a formal request to the Change Advisory Board (CAB) for approval.
  4. 4Deploy the patch to production network devices during an authorized maintenance window.
  5. 5Perform post-deployment auditing and functionality verification.

Answer

The correct order of the patch management lifecycle steps is: 1) Identify and evaluate vendor patch releases, 2) Test the software patch in an isolated lab environment, 3) Submit a formal request to the Change Advisory Board (CAB) for approval, 4) Deploy the patch to production network devices during an authorized maintenance window, and 5) Perform post-deployment auditing and functionality verification.
The standard patch management lifecycle follows a structured sequence: discovering vendor patches, testing updates in a non-production lab, securing approval through change management processes, deploying during an authorized maintenance window, and completing post-deployment audits to confirm stability.

Step-by-Step Solution

1
Identify patch requirements
Discovers vendor security releases and evaluates applicability.
The patch lifecycle must begin with identifying updates before any operational changes are planned.
2
Validate the patch in a lab environment
Confirms software stability without impacting production networks.
Lab testing identifies unexpected bugs or configuration incompatibilities prior to broad deployment.
3
Obtain organizational change authorization
Secures approval from the Change Advisory Board and schedules the work.
Change management ensures stakeholders are aware of risks, scheduling, and rollback strategies.
4
Execute production deployment
Installs the patch on active network routers.
Applying patches within an authorized maintenance window minimizes operational disruption to end users.
5
Perform post-patch validation and audit
Confirms successful patch installation and system stability.
Post-deployment verification ensures vulnerabilities are mitigated and services remain fully functional.
