You need to identify the requirements for the voice pilot project. Which two actions should you perform? Each correct answer presents part of the solution.

For users to make and receive calls in Microsoft Teams using Microsoft's phone system, they need both a phone number assigned to their account and the necessary licensing to enable calling capabilities, typically including a Phone System license.

Deploying a Session Border Controller (SBC) is required for Direct Routing, which is an alternative to Microsoft Calling Plans, and thus not a universal requirement for a voice pilot if Calling Plans are used.

A Microsoft Teams Calling Plan license is essential for users to make and receive calls to and from the Public Switched Telephone Network (PSTN) using Microsoft Teams, which directly fulfills a core requirement for a voice pilot project.

Creating a dial plan defines how phone numbers are translated and routed, but it's a configuration step after users are licensed and have phone numbers/calling plans, not a primary requirement for starting a voice pilot itself.

"Purchase a Calling Plan for Litware" is vague; Calling Plans are typically purchased per user or in bundles and then assigned, making option C, "Purchase a Calling Plan for each user," more specific and actionable for a pilot project requirement.
