The correct answer is A. The appliance has been configured to use an external Single Sign-On server. B. The administrator did not export the appliance configuration. Upgrading a vCenter Appliance to vSphere 6.x can be prevented by using an external Single Sign-On server configuration or by not exporting the appliance configuration prior to upgrade.

Why each option
Upgrading a vCenter Appliance to vSphere 6.x can be prevented by using an external Single Sign-On server configuration or by not exporting the appliance configuration prior to upgrade.
An appliance configured with an external Single Sign-On server often requires specific migration or converge procedures before a direct upgrade to vSphere 6.x can successfully complete, making it a potential blocking condition.
Not exporting the appliance configuration, which includes critical data and settings, would prevent a successful and recoverable upgrade process, as data migration from the source appliance is a key step.
An appliance with an embedded Platform Services Controller is the recommended and well-supported configuration for upgrades and would not prevent a vSphere 6.x upgrade.
Placing the ESXi host into Maintenance Mode is not a prerequisite for upgrading the vCenter Server Appliance itself, as the upgrade process focuses on the appliance VM.
