How should you create the SD-WAN zones?
To create a base SD-WAN configuration that can be easily applied to new sites with minimum changes, you should create SD-WAN zones with templates for each connectivity type. This template-based approach allows you to define standard SD-WAN rules and Performance SLAs for different connectivity scenarios (broadband, MPLS, LTE, etc.), which can then be rapidly deployed to new spoke sites by simply applying the appropriate template rather than manually configuring each site.

Question 4 Domain 4 Configure and manage Teams meetings, webinars, and town halls
You have a Teams Phone deployment that has users in Canada and the United States.
You have a Session Border Controller (SBQ in Calgary and an SBC In New York City. Both SBCs are connected to Direct Routing. You plan to implement toll bypass for the users in Canada. The solution must meet the following requirements:
* Prioritize the New York City SBC for calls to numbers in the United States.
* Leverage the Calgary SBC for resiliency if the New York City SBC is unavailable.
You create a PSTN usage named Canada and associate this policy to a voice routing policy.
Which two voice routes should you create with the Canada PSTN usage? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
To implement toll bypass for Canada users while prioritizing the New York City SBC for US calls and using Calgary SBC for resiliency, you should create two voice routes with the Canada PSTN usage: First, create a voice route for +1 (United States and Canada numbers) with the New York City SBC configured as the primary route (priority 1) and the Calgary SBC as the secondary/backup route (priority 2). This ensures that calls to US numbers primarily use the New York City SBC for optimal routing. Second, create a voice route for Canadian toll-free or other specific number patterns with the Calgary SBC as priority 1, ensuring Canadian toll calls bypass international routing by using the local Calgary SBC. This two-route approach achieves both the prioritization requirement for US calls and the resiliency requirement using the appropriate regional SBCs.

Question 7 Domain 2 Configure and manage Teams Phone
You have a Microsoft Teams Phone deployment.
You plan to deploy 25 shared Android devices as phones for a front desk.
You need to ensure that when a phone handset is picked up. the phone autodials to a centralized reception. The solution must minimize administrative effort.
What should you do?
To ensure 25 shared Android devices autodial to a centralized reception when a handset is picked up while minimizing administrative effort, configure a call forward rule on the shared devices. This involves setting up automatic call forwarding at the device level to redirect incoming calls or setting up auto-dialing rules. This approach requires minimal per-device configuration and centralizes the management through Teams admin policies rather than individually configuring each device manually.
