Following a critical vulnerability advisory affecting an enterprise syslog management server, a network operations administrator is scheduled to deploy a vendor-provided operating system hotfix. To follow proper change management procedures and minimize operational downtime during deployment, which step should the administrator execute before installing the patch in production?
- Perform a verified full system backup and validate the hotfix within an isolated sandbox environment.Cevap
- BApply an incremental system backup immediately and deploy the patch directly to the production cluster without prior lab staging.
- CDeploy the hotfix to the live primary server node first to evaluate system stability prior to developing a formal rollback plan.
- DReconfigure network access control list rules to block syslog port traffic during the update rather than establishing system restoration points.
Cevap
Perform a verified full system backup and validate the hotfix within an isolated sandbox environment.
Safe software maintenance requires validating patches in a non-production staging or sandbox environment to detect adverse interactions, alongside creating a verified full system backup to ensure rapid rollback if issues arise during deployment.
