A network engineering team is preparing to deploy a vendor-released maintenance patch to address a critical security vulnerability across multiple enterprise edge routers. To ensure network stability and adhere to standard change management procedures, which of the following operational steps should be completed prior to applying the patch to production hardware? (Select TWO.)
- Perform a verified baseline configuration backup of all target devices prior to initiating the update process.Cevap
- Test and validate the patch inside an isolated laboratory environment that mirrors the production hardware configuration.Cevap
- CDeploy the patch simultaneously to all production routers during peak operational hours to minimize the vulnerability exposure window.
- DExecute a full restoration from an incremental backup directly onto live routers immediately following the patch deployment.
Cevap
Prior to deploying software maintenance patches to production network devices, engineers must perform a verified baseline backup of device configurations and thoroughly test the patch in an isolated lab environment that mirrors production.
Safe patch management procedures mandate creating a full, verified baseline configuration backup and validating software patches in an isolated staging/lab environment prior to production deployment. These steps ensure configuration recovery capability and minimize unexpected operational downtime.
