A cloud architect is tasked with providing a design for integration with a third-party system.

The following requirements have been identified:
• When a user requests a virtual machine, vRealize Automation should pass the user selected application name with its key to the third-party system.
• The application list could be updated weekly following the architecture approval meeting. It currently has 250 items.
• Impacts to the vRealize Automation virtual machine request screen’s performance should be minimized.

What would be the best solution to meet these requirements?

A. Create a vRO action to return application values as “Array\String” by reading from the third-party system dynamically, Create a display drop-down custom property with external values and map it to the vRO action.

B. Design a schedule vRealize Orchestrator (vRO) workflow to read values from the third-party system and store in vRO, Create a vRO action to return application values stored in vRO as “Properties”, Create a Display drop-down custom property with external values and map it to the vRO action.

C. Create a Display drop-down custom property with external values and provide AJAX call information to the third-party system.
D. Design a schedule vRO workflow to read values from the third-party and store in vRO, Create a vRO action to return application values stored in vRO as “Array\String”, Create a Display drop-down custom property with external values and map it to the vRO action.
