Really clear question. Unassign +14165555555, change its usage type, then assign it to a new resource account for reception area.

Ajay 6

Unassign +14165555555, change usage type, assign to new resource account. Has to be unassigned first so you can convert it, then you link it to the call queue using the resource account. Pretty sure that's how MS Teams wants it done, unless I missed something?

Correct Answer:

Answer Areas Target 1: E. Unassign +14165555555. Target 2: G. Change the usage type of +14165555555. Target 3: F. Assign +14165555555 to a new resource account for the reception area.

Explanation

To transition a phone number from a physical device (Common Area Phone/User usage) to a Call Queue (Service usage), you must follow a specific lifecycle:

Unassign: A number cannot be modified or reassigned while it is actively linked to a user or device. You must first remove the current association.
Change Usage Type: Microsoft distinguishes between "User" (Subscriber) numbers and "Service" numbers. Call Queues and Auto Attendants require Service numbers. You must convert the usage type in the Teams Admin Center or via PowerShell to make it compatible with a Resource Account.
Assign to Resource Account: Once converted, the number is assigned to the Resource Account associated with the Call Queue to route incoming calls.

Q: 2

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

Kevin N. 6

Option B is what you want here. Set-CsUser is used to enable Teams Direct Routing and assign the phone number via PowerShell. The other cmdlets don't actually enable the user for Direct Routing. Pretty sure on this, but if someone has a different use case let me know.

Rowan J.

Its B for enabling Direct Routing via PowerShell since only Set-CsUser lets you set both the phone number (LineURI) and Enterprise Voice. The other options don't handle both at once from what I remember-unless Microsoft changed something recently? Open to corrections if rules have shifted.

Correct Answer:

Explanation

To enable a user for Microsoft Teams Direct Routing using PowerShell, you must configure their account with their specific phone number and enable them for Enterprise Voice. The Set-CsUser cmdlet is the correct tool for this task. It allows an administrator to set the essential -OnPremLineURI parameter to the user's E.164 phone number and the -EnterpriseVoiceEnabled parameter to $true. These settings configure the user's account to route calls via the on-premises Session Border Controller (SBC) defined in the Direct Routing configuration.

Why Incorrect

A. Set-CsCallingLineIdentity: This cmdlet is incorrect because it is used to create or modify Calling Line ID (Caller ID) policies, which control the phone number displayed on outgoing calls, not to enable a user for a specific voice routing method.
C. Set-CsOnlineVoiceUser: This cmdlet is incorrect for this specific task because it does not have the -OnPremLineURI parameter, which is required to assign a phone number for Direct Routing. It is typically used for other voice configurations.
D. Set-CsUserServicesPolicy: This cmdlet is incorrect as it is used to manage user services policies that control features like unified contact store, presence, and archiving, which are not directly related to enabling voice routing.

References

1. Microsoft Docs - Enable users for Direct Routing: This official documentation explicitly details the steps to enable a user for Direct Routing.

Reference: In the "Enable user and assign a phone number" section

the document states: "You can use the Set-CsUser cmdlet to configure the phone number and enable Enterprise Voice and voicemail for a user." It provides the following example command: Set-CsUser -Identity "[email protected]" -OnPremLineURI "tel:+14255550100" -EnterpriseVoiceEnabled $true -HostedVoiceMail $true.

Makes sense, the order should be Create valid emergency addresses, then Acquire phone numbers, finally Assign phone numbers to users. That's the workflow Teams expects for Operator Connect.

Jack L. 6

Create valid emergency addresses > acquire phone numbers > assign phone numbers to users. If you try to skip the emergency address step, Teams blocks the rest, so order really matters here for Operator Connect.

Nah, gotta disagree a bit here. HR needs Cloud Video Interop since they have to support third-party VTC gear, not Teams Rooms.

Ethan K. 6

Direct Guest Join for third-party join, Proximity join for casting content. This fits the requirements best as far as I know.

Noah C. 5

If the casting piece required users to already be in a Teams meeting, I'd say Companion mode might fit. But since it's just about casting content from their devices generally, Proximity join is the correct one for that. Direct Guest Join is definitely for third-party meeting one-touch access. Anyone see a scenario wher

Attendant routing
Longest idle
Round robin
Serial routing

18 comments in the community discussion

Olivia J. 5

CQ1: Round robin, CQ2: Attendant routing. Round robin splits calls evenly, which is what "balance" means here. Attendant is the only one that rings all agents at once. Pretty sure this is correct, but I know some confuse longest idle for CQ1.

Olivia S. 4

Nah, I think it's CQ1: Round robin and CQ2: Attendant routing. Serial routing is a trap here, since it doesn't ensure balanced distribution. Pretty sure this lines up with how Teams works, but let me know if you see it differently.

Q: 7

Option B and E, saw a similar question in exam reports. Both needed for full fix.

Quinn J. 1

B, E

Correct Answer:

B, E

Explanation

For Direct Routing to function correctly, the user must be assigned a LineURI with the PhoneNumberType set specifically to DirectRouting. The current configuration likely treats the number as a Microsoft Calling Plan number or is in an inconsistent state. Running Option B (Set-CsPhoneNumberAssignment) correctly attributes the number to the Direct Routing service. Additionally, the user is currently assigned a specific voice routing policy ("VIC-All"). In many Direct Routing configurations, clearing a custom policy to use the global default or ensuring the policy is re-evaluated by setting it to $null (Option E) is a necessary step to reset the routing logic and ensure the SBC handles the traffic correctly.

Why Incorrect

Option A: This command removes the phone number assignment entirely, which would prevent the user from making or receiving any calls.

Option C: Set-CsOnlineVoiceUser is a legacy cmdlet primarily used for Skype for Business Online; modern Teams environments use Set-CsPhoneNumberAssignment.

Option D: Disabling EnterpriseVoiceEnabled would strip the user of all Teams Phone functionality, making it impossible to place or receive calls.

Right, it's D (User1 in TAC), then F (User2 receive-only and no change rights), then A (User1 finishes in Teams client). Starts with admin config, limits User2's permissions, then minimal client disruption at the end. I think this matches least privilege and workflow. Anyone disagree?

Liam G. 3

Minimal disruption only works if admin sets up in TAC first, then configures User2’s receive-only and settings block, then has User1 confirm as delegate in client.

Q: 9

DRAG DROP Your company has a main office in New York and a branch office in Calgary. All offices connect to each other by using a dedicated WAN. You have a Microsoft Teams Phone deployment. You need to recommend a Direct Routing solution that meets the following requirements: • If a Session Border Controller (SBQ fails in the New York office, PSTN services must remain available through a local PSTN egress in New York. The Calgary office must prioritize a local PSTN egress and ensure that PSTN services remain available in the event of a local SBC outage. • The number of SBCs must be minimized. What should you recommend for each office? To answer, drag the appropriate components to the correct offices. Each component may be used once, more than once, or not at all.

A cross-site SBC pair
A local redundant SBC pair
A single SBC
PSTN over WAN

16 comments in the community discussion

Arjun U. 5

New York: A local redundant SBC pair, Calgary: PSTN over WAN. This setup lets NY handle its own failover locally, while Calgary leverages the existing New York SBC for backup and keeps hardware counts low.

QuietConsultant6493 4

New York: local redundant SBC pair, Calgary: PSTN over WAN. That's the only way to keep local PSTN failover in NY and still minimize total SBCs, since Calgary can use the WAN for backup if its local SBC goes down. Pretty sure this covers all the requirements, but open to other ideas.

Correct Answer:

Answer Areas New York: B. A local redundant SBC pair Calgary: D. PSTN over WAN

Explanation

New York Office: The requirement states that if an SBC fails, PSTN services must remain available through a local PSTN egress. To achieve local failover within the same site without relying on another geographical location, you must deploy a local redundant SBC pair (typically configured as a High Availability cluster). This ensures that the failure of a single physical unit does not disrupt the local egress.

Calgary Office: The requirement is to prioritize local egress but ensure availability during an outage while minimizing the number of SBCs. By selecting PSTN over WAN, Calgary can use the redundant SBC infrastructure in New York as a backup path. This satisfies the survivability requirement without needing to deploy a redundant pair at the branch site, thus minimizing hardware.

Marketing agents can log in and out, so Yes for that. Outbound caller ID isn't forced unless a caller ID policy is applied, which is missing here, so No. For the order, admin can't specify who gets called first when using Team-based serial routing (rings alphabetically), so that's also No. Pretty sure about these-fe
