Your company has implemented a new policy requiring all network devices to run the latest secure software. You must update a router with a patch that the manufacturer released to fix a recently disclosed vulnerability. Which step is most important to ensure the patch is applied correctly and does not disrupt service?
Restart the router immediately after installing the patch.
Read the manufacturer's release notes for the patch.
Apply the patch during normal business hours to address issues quickly.
Verify that the patch is compatible with your router's model and current operating system.
Before deploying any patch, you must verify that it is compatible with the exact router model and operating-system version in use. Applying an incompatible image can corrupt the device, cause unexpected reboots, or introduce new faults, negating the security benefit and creating downtime. Reading release notes, rebooting after installation, and choosing an appropriate maintenance window are all good practices, but they come after you have confirmed that the patch will work on the target hardware and software.
