Correct answers: A, C, D
Explanation
When managing software image upgrades using vManage, it is critical to follow best practices to minimize network disruptions and ensure a smooth upgrade process. Verifying compatibility, enabling rollback, and properly staging the upgrade by uploading and distributing the image before activation are essential steps. Scheduling during peak hours or activating the image on all devices simultaneously can lead to unnecessary risks and disruptions.
- A. Correct.
Verifying compatibility ensures that the new software image is supported by the existing hardware and configurations, reducing the risk of upgrade failures.
- B. Incorrect.
Scheduling upgrades during peak business hours is not recommended as it can disrupt live network operations.
- C. Correct.
Enabling automatic rollback helps to quickly revert to the previous version if the upgrade fails, minimizing downtime.
- D. Correct.
Uploading and distributing the software image before activating it ensures that the process is staged and reduces the risk of disruptions during activation.
- E. Incorrect.
Activating the new image on all devices simultaneously can lead to widespread disruptions in case of an issue and is not a recommended practice.
