MS-900 Describe cloud concepts Practice Question
Contoso Ltd. is a global consulting firm with 5,000 employees. They use Microsoft 365 E5 and have recently deployed Microsoft Copilot for Microsoft 365 to enhance productivity. The IT team wants to ensure that users' interactions with Copilot are compliant with the company's data retention policies. They need to retain all Copilot interactions for 7 years for legal reasons. Which Microsoft Purview solution should the IT team implement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create retention policies for Copilot interactions
Retention policies in Microsoft Purview can be applied to Copilot interactions stored in Exchange Online and SharePoint Online to retain them for 7 years. Option A is incorrect because sensitivity labels classify data but do not enforce retention. Option C is incorrect because eDiscovery is for searching and exporting content, not setting retention. Option D is incorrect because Data Loss Prevention (DLP) policies prevent data loss but do not retain data for legal hold.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Apply sensitivity labels to Copilot data
Why it's wrong here
Sensitivity labels classify and protect content based on sensitivity, but they do not enforce time-based retention or deletion. The stem requires retaining Copilot interactions for a fixed 7-year period, which demands a retention label or policy from Microsoft Purview Records Management or Data Lifecycle Management. This option is tempting because sensitivity labels can apply encryption and visual markings, and would be correct if the goal were to restrict access or prevent unauthorised sharing of Copilot data rather than manage its retention schedule.
- ✓
Create retention policies for Copilot interactions
Why this is correct
Retention policies in Microsoft Purview apply to Copilot interaction data stored in Exchange Online, letting administrators set a seven-year retention duration. This directly satisfies the legal requirement to retain all Copilot interactions for seven years without relying on manual preservation.
- ✗
Set up eDiscovery cases for Copilot data
Why it's wrong here
eDiscovery cases support identifying, holding and exporting content for legal matters, but they do not automatically apply a seven-year retention period to all Copilot interactions. They are tempting for litigation-driven preservation, yet the requirement is ongoing policy-based retention, which retention policies and labels deliver.
- ✗
Configure Data Loss Prevention (DLP) policies
Why it's wrong here
DLP policies detect and block sensitive information flows; they neither retain Copilot interaction records nor enforce a seven-year retention period. DLP is the right choice for preventing data leakage, but the stem's legal retention obligation requires retention policies or labels instead.
