How does an administrator obtain new NIOS releases?

Comprehensive and Detailed In-Depth Explanation:Obtaining new NIOS software releases follows a standardized process tied to Infoblox’s support infrastructure:

Official Method:New releases (e.g., NIOS 8.6.x) are available for download from theInfoblox Support Portal(https://support.infoblox.com ) under the "Downloads" section. Admins log in with valid credentials, select the appliance model, and download the .upgrade file.

Options Analysis:

A:"Grid > Software > Download" isn’t a valid path in Grid Manager. The UI supports uploading and distributing releases (Grid > Upgrade), but not direct downloading. Incorrect.

B:Technical Support can assist with issues or provide files in rare cases (e.g., beta releases), but it’s not the standard method—self-service via the portal is preferred. Incorrect.

C:Account Managers handle sales, not software distribution. "Support Bundle" is also a misnomer—it’s for diagnostics, not upgrades. Incorrect.

D:The support portal is the documented, primary source for NIOS releases, aligning with INE’s focus on Grid upgrade procedures. Correct.

Steps:Download the file, upload it via Grid Manager (Grid > Upgrade > Upload), and initiate the upgrade process.

Practical Example:In an INE lab, you’d download NIOS 8.6.2 from the portal, upload it, and test a Grid-wide upgrade, troubleshooting any distribution failures.References:Infoblox NIOS Administrator Guide – Obtaining Software Releases; INE Course Content: NIOS DDI Grid Deployment.
