The correct answer is Microsoft Purview retention policies and eDiscovery. This solution works because Purview retention policies can be applied directly to Teams chat messages to enforce a 7-year retention period automatically, while eDiscovery (now part of Purview) provides the search and hold capabilities needed to locate and export those retained messages for legal or regulatory review. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of how Microsoft 365 compliance solutions map to specific retention requirements—a common trap is confusing retention policies with sensitivity labels, which only classify data, or with DLP policies, which prevent data loss but do not enforce time-based retention. Remember the memory tip: “Retain with Retention, Search with eDiscovery”—if the scenario mentions a mandatory time period and legal search, always pair Purview retention policies with eDiscovery.
SC-100 Practice Question: Design security operations, identity, and compliance capabilities
This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization is required to retain all Microsoft Teams chat messages for 7 years due to regulatory compliance. You need to design a solution that automatically retains and, if needed, e-discovery searches these messages. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview retention policies and eDiscovery
Option A is correct because Microsoft Purview retention policies can be applied to Teams chats to retain them for a specified period, and eDiscovery can search retained messages. Option B is wrong because sensitivity labels classify but do not enforce retention. Option C is wrong because DLP policies prevent data loss, not retention. Option D is wrong because Azure Policy applies to Azure resources, not Microsoft 365 data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure Policy
Why it's wrong here
Azure Policy governs Azure resources, not Microsoft 365 services like Teams.

Sensitivity labels auto-labeling
Why it's wrong here
Sensitivity labels classify data but do not enforce retention periods.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
