Which two conditions would prevent an administrator from upgrading an existing vCenter Server Appliance to vSphere 6.x? (Choose two.)
The correct answer is A. The administrator did not export the appliance configuration. D. The appliance has been configured to use an external Single Sign-On server. Failing to export the appliance configuration and using an external standalone SSO server are two conditions that block or prevent a successful vCenter Server Appliance upgrade to vSphere 6.x.

Why each option
Failing to export the appliance configuration and using an external standalone SSO server are two conditions that block or prevent a successful vCenter Server Appliance upgrade to vSphere 6.x.
The vCSA upgrade process requires an exported appliance configuration to migrate settings and data; without this export the upgrade wizard cannot complete the migration of appliance-specific configuration, causing the upgrade to fail.
The ESXi host running the vCSA does not need to be in Maintenance Mode for the upgrade process; the appliance upgrade is performed in-place or via migration without that requirement.
An embedded PSC is a fully supported and common vSphere 6.x topology; it does not prevent an upgrade and is one of the recommended deployment configurations.
vSphere 5.x environments using an external standalone SSO server are not directly upgradeable via the standard vCSA upgrade path, because vSphere 6.x integrates SSO within the Platform Services Controller and does not support upgrading from a standalone external SSO topology.
