A compliance officer needs to ensure that all documents in a Microsoft Teams channel are automatically retained for 3 years after creation and then permanently deleted. The retention policy should apply only to the specific channel, not the entire team. Which approach should the officer use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Create a retention policy in Microsoft Purview and select the location 'Teams chats' for the entire team
Incorrect. Selecting 'Teams chats' applies to all channels in the team, not a single channel.
B
Best answer
Create a retention policy in Microsoft Purview and select the location 'Teams channel messages', then specify the channel name
Correct. The retention policy can target a specific channel by using the 'Teams channel messages' location and specifying the channel name in the scope.
C
Distractor review
Publish a retention label to the channel and configure auto-application rules based on creation date
Incorrect. Labels can be auto-applied, but the scenario specifically requires a policy that retains and deletes without user interaction or label assignment.
D
Distractor review
Use Exchange Online PowerShell to create a retention policy for the channel mailbox
Incorrect. While PowerShell can be used, the simplest and correct native method is through the Purview compliance portal with the correct location selection.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A company recently added the custom domain 'contoso.com' to their Microsoft 365 tenant. Users report that they cannot receive external email sent to their new domain addresses. The administrator confirmed that the domain status shows 'Active' in the Microsoft 365 admin center. What is the most likely cause of this issue?
Question 2
A company has 500 users across Sales, Marketing, and IT departments. User objects are synced from on-premises Active Directory to Microsoft Entra ID using Azure AD Connect. Each department requires different Microsoft 365 license plans (e.g., Sales needs E3, Marketing needs Business Premium, IT needs E5). The administrator wants to automatically assign the appropriate license based on the department attribute without manual intervention. Which approach should the administrator use?
Question 3
A company has purchased 1000 Microsoft 365 E5 licenses and wants to automatically assign licenses to users based on their department attribute, which is synchronized from on-premises Active Directory. The department attribute is stored in Azure AD. Which automated method should the administrator use to achieve this?
Question 4
A company has just purchased Microsoft 365 Business Standard and added the custom domain 'fabrikam.com' to the tenant. They want to verify domain ownership. Which DNS record type must they add to their DNS provider?
Question 5
A company plans to migrate their email from an on-premises Exchange server to Exchange Online. They want to ensure that during the migration, mail sent to users who have already been migrated is delivered to Exchange Online, while mail for non-migrated users is delivered to on-premises. Which type of domain configuration should they use?
Question 6
A company has registered the custom domain 'contoso.com' and wants to host email for the subdomain 'sales.contoso.com' in Exchange Online. They have already verified the root domain. What additional step is required?
FAQ
Questions learners often ask
What does this MS-102 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Create a retention policy in Microsoft Purview and select the location 'Teams channel messages', then specify the channel name — In Microsoft Purview, retention policies for Teams can target specific channels or chats. To apply retention to a single channel (not the entire team), the policy must be defined at the channel level using the 'Teams channel messages' location and specifying the channel name. Option A is correct. Option B is incorrect because a policy at the team level applies to all channels in that team. Option C is incorrect because labels are applied manually or automatically, but they do not enforce a fixed retention period and deletion schedule without additional configuration; the scenario requires a policy, not labels. Option D is incorrect because PowerShell could be used, but the native admin center method is the simplest and most appropriate.
