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?

VMware Update Manager supports direct upgrades from ESXi 5.5 to 6.5 without requiring an intermediate upgrade to 6.0; a version prerequisite gap would not cause a Compliant status but would surface as an error during remediation.

Third-party software installed on a host would typically cause a Non-Compliant or Unknown status against a baseline, not a Compliant status, since the software may conflict with baseline requirements.

Update Manager determines compliance by comparing a host's installed software against the patches or upgrades defined in attached baselines. If no upgrade baseline is attached to the host, cluster, or datacenter, the scan has nothing to evaluate and returns Compliant by default, meaning the administrator must first attach an upgrade baseline before remediation is possible.

Unsupported hardware would be flagged during the hardware compatibility check or remediation pre-check phase and would result in a failure or warning, not a Compliant status during a baseline scan.
