Nutanix documents Logbay as the preferred and supported mechanism for efficient platform log collection. The AHV administration guide states that you can use Logbay only after the CVM is installed on the node or the AHV compute node has been added to the cluster, which directly matches the wording in option A. Nutanix’s web-console guidance also points administrators toward Logbay as the preferred collection method rather than relying only on manual UI collection.

The other options describe tools or behaviors that do not match Nutanix’s documented collection path for this scenario. Panacea is not the standard answer for supported cluster log-bundle collection in the way described. Storage policy reports are not substitutes for host/CVM diagnostic logs, and ADS does not function as an automatic diagnostic bundle exporter for arbitrary contention events. Because the question asks for both the supported approach and a key prerequisite, Logbay with the documented availability condition is the most precise Nutanix answer. Therefore A is correct.
