A network administrator is preparing to perform a routine firmware update on enterprise network switches during a scheduled maintenance window. Which TWO of the following tasks should be completed prior to deploying the patch to the production environment? (Select TWO.)
- Test the firmware update in an isolated lab or staging environment.Cevap
- Create a baseline backup of the current operating system image and configuration file.Cevap
- CDeploy the update immediately to all production devices without prior testing to minimize vulnerability exposure.
- DPerform a full system restoration using only an incremental backup file before initiating the update.
Cevap
The administrator should test the firmware update in an isolated lab environment and create a baseline backup of the current configuration and operating system image prior to production deployment.
Before deploying patches to production, administrators must test updates in a lab or staging environment to identify potential operational issues and back up active configurations and system software to allow for rapid rollback if failure occurs.
