Palo Alto Networks Certified Network Security Administrator (PCNSA)Initial Configuration and ManagementEasy
A network technician is performing a software update on a Palo Alto Networks firewall. They have downloaded the new PAN-OS image and are ready to install it. What is the recommended next step AFTER downloading the image but BEFORE rebooting the firewall?
- AInstall the downloaded PAN-OS image.
- BUpdate the antivirus and anti-spyware definitions.
- CExport the device configuration to an external server.
- DVerify the integrity of the downloaded image using its hash.
Show answer & explanationAnswer & explanation
Correct answer: A. Install the downloaded PAN-OS image.
After successfully downloading the PAN-OS image, the next logical step before a reboot is to install the image. The installation process stages the new software for the subsequent reboot.
Why the other options are wrong
- B. Updating definitions is a separate, routine maintenance task and not directly part of the PAN-OS software update sequence.
- C. Exporting configuration is a good practice before any major change, but it's typically done prior to the download/install process, or as a separate backup step, not directly between download and install.
- D. While verifying integrity is a crucial step, it should ideally be done immediately after download and before attempting to install, to ensure the image is not corrupt or tampered with.
PAN-OS Installation Step
After downloading a PAN-OS software image to the firewall, the next step is to install it. This action stages the new operating system for activation upon the next reboot.
- Follows image download.
- Precedes firewall reboot.
- Prepares the system for the new OS version.
