An administrator wants to upgrade ESXi 5.5 hosts to ESXi 6.5 using Update Manager. When performing a scan for baseline compliance, the host's status is marked Compliant. Which has happened?

VUM supports direct upgrade paths from ESXi 5.5 to 6.5; a host does not need to be at version 6.0 first, so this version restriction does not apply.

Third-party software on a host would typically cause a Non-Compliant or Unknown status for specific patches, not a blanket Compliant result for an upgrade scan.

Update Manager determines compliance by comparing a host's current patch and version state against the contents of an attached baseline. If no upgrade baseline is attached, VUM has nothing to measure the host against and therefore reports the host as Compliant by default. The administrator must attach an appropriate upgrade baseline before a meaningful compliance scan result can be generated.

Unsupported hardware would manifest as a failed pre-check or remediation error, not a Compliant status during the scan phase.
