MS-700 Manage Teams, Channels, Chats, and Apps Practice Question
You are the Teams administrator for Contoso. A team named 'Field Ops' was created from a Microsoft 365 group and includes a channel named 'Dispatch'. The Dispatch channel must be visible only to the 12 dispatchers in the team, and only those dispatchers should be able to post messages in it. You need to configure the channel so that membership is limited to the dispatchers while all other team members cannot see or join it. What should you do?
⚠ Common exam trap
The trap here is assuming that channel moderation or a security group assignment can hide a channel from other team members, when only changing the channel membership type to Private actually restricts visibility and membership.

Correct answer & explanation
✓
Change the Dispatch channel's membership type to Private, then add the 12 dispatchers as members of the channel.
A private channel is the only channel membership type that limits both visibility and participation to an explicitly defined set of members within the parent team. By converting Dispatch to a private channel and adding the dispatchers as channel members, non-dispatchers in Field Ops cannot see or post in the channel, while the dispatchers retain access. Shared channels and moderation policies address different collaboration or posting needs and do not provide the required exclusion.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Change the Dispatch channel's membership type to Private, then add the 12 dispatchers as members of the channel.
Why this is correct
Changing the channel's membership type to Private makes the channel available only to the users explicitly added as channel members, even though they remain members of the parent team. Adding the dispatchers as channel members satisfies both visibility and posting restrictions because non-members cannot see or post in a private channel. This is the supported way to scope a channel to a subset of team members in Microsoft Teams.
- ✗
Use a channel moderation policy to limit who can post, and rely on the team's existing membership to control visibility.
Why it's wrong here
Channel moderation can restrict who may post, but it does not hide the channel from other team members. The requirement is that non-dispatchers must not see or join the channel, and moderation alone leaves the channel visible to everyone in the team. Because visibility is the core constraint, moderation settings cannot satisfy the scenario by themselves.
- ✗
Create a new security group containing the dispatchers, then assign the group to the Dispatch channel.
Why it's wrong here
Microsoft Teams does not assign security groups directly to a channel to control channel membership. Channel membership for private channels is managed through the Teams client or PowerShell channel member cmdlets, not by attaching a security group to the channel object. Creating a security group would not restrict visibility of the Dispatch channel to the dispatchers, so this does not meet the requirement.
- ✗
Change the Dispatch channel's membership type to Shared and add the dispatchers as shared channel members.
Why it's wrong here
A shared channel is designed for people who are not members of the parent team, and it does not hide the channel from team members; it changes who can be invited. It also does not restrict posting to only the dispatchers in the way a private channel does. Because the requirement is to exclude most of the Field Ops team from the channel, shared channel membership type is the wrong choice here.
