MS-700 Question #240: Real Exam Question with Answer & Explanation

Question

Your company has a branch office in Seattle. You have a Teams Phone deployment. You need to create a policy to ensure that all the users in the Seattle office can use the same phone number for outbound calling. How should you complete the PowerShell command? To answer, select the appropriate options in the answer area.

Explanation

This question tests knowledge of Microsoft Teams Phone Caller ID policies, specifically how to configure a shared outbound calling number for a group of users in a branch office using PowerShell.

Approach. The correct approach is to use 'New-CsCallingLineIdentity' to create a Caller ID policy that substitutes the outbound caller ID with a shared service number. Key parameters include '-Identity' (to name the policy, e.g., 'Seattle'), '-CallingIDSubstitute Service' (to indicate a service/resource account number will be used), '-ServiceNumber' (to specify the shared phone number), and '-EnableUserOverride $false' (to prevent users from changing it). After creation, the policy is assigned to users with 'Grant-CsCallingLineIdentity -Identity <UPN> -PolicyName Seattle'. This ensures every user in Seattle presents the same phone number on outbound calls.

Concept tested. Microsoft Teams Phone - Caller ID Policy (CsCallingLineIdentity) PowerShell cmdlets: creating and assigning a shared outbound caller ID using New-CsCallingLineIdentity and Grant-CsCallingLineIdentity with the -CallingIDSubstitute and -ServiceNumber parameters.
