MS-720 Question #101: Real Exam Question with Answer & Explanation

Question

You have a Microsoft Teams Phone deployment You assign a Microsoft 365 E5 license lo a user named User1. You need to enable User1 for Direct Routing. Which PowerShell cmdlet should you run?

Options

• ASet-CsCallingLineIdentity
• BSet-CsUser
• CSet-CsOnlineVoiceUser
• DSet-CsUserServicesPolicy

Explanation

Note: The marked answer (A) appears to be incorrect. The actual correct answer is B. Set-CsUser.

Set-CsUser is the cmdlet used to enable a user for Direct Routing by setting parameters like -EnterpriseVoiceEnabled $true, -HostedVoiceMail $true, and -OnPremLineURI (or -LineURI) to assign the phone number. This is precisely what "enabling for Direct Routing" means in a Teams Phone deployment.

Why the distractors are wrong:

• A. Set-CsCallingLineIdentity - Configures Caller ID policies (what number callers see when dialed), not Direct Routing enrollment. This is the most plausible trap answer because it sounds phone-related.
• C. Set-CsOnlineVoiceUser - A legacy/deprecated cmdlet that no longer applies to modern Direct Routing configurations.
• D. Set-CsUserServicesPolicy - Controls user-level services like interop and file transfer; unrelated to voice routing.

Memory tip: Think "CsUser = configure the user's voice settings." Direct Routing routes calls through the user, so you configure the user object itself with Set-CsUser. CallingLineIdentity = caller ID only - it changes what others see, not how the user is routed.

If this question came from a practice exam, I'd flag it as having an answer key error - you may want to verify against official Microsoft Learn documentation for MS-721.
