Quick Answer
The correct answer is Microsoft Purview Information Protection, Microsoft Purview DLP, and Microsoft Purview eDiscovery. This combination directly addresses every requirement: Purview Information Protection auto-classifies and labels sensitive data in SharePoint and OneDrive, while Purview DLP policies block external sharing of 'Highly Confidential' files and trigger alerts, with Endpoint DLP extending that control to monitor copy/paste and print actions on endpoints. All audit events flow into Microsoft Sentinel for centralized correlation, and Purview eDiscovery, paired with retention policies, satisfies regulatory mandates for data preservation and discovery. On the Microsoft Cybersecurity Architect exam, this scenario tests your ability to distinguish Purview’s integrated data security stack from adjacent tools like Defender for Cloud Apps or Intune, which lack endpoint DLP or eDiscovery capabilities. A common trap is assuming Defender for Cloud Apps alone can block endpoint actions, but it cannot—only Endpoint DLP provides that granular control. Memory tip: think "Label, Lock, Log, and Locate"—Purview Information Protection labels, DLP locks risky actions, audit logs feed Sentinel, and eDiscovery locates retained data.
This SC-100 practice question tests your understanding of design security solutions for applications and data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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, Contoso Ltd., is a multinational company with 50,000 employees. They use Microsoft 365 E5, Azure, and Microsoft Sentinel. The security team wants to implement a data security solution that meets the following requirements:
1. All sensitive data stored in SharePoint Online and OneDrive for Business must be automatically classified and protected using sensitivity labels. 2. When a user attempts to share a file labeled 'Highly Confidential' with an external user, the action should be blocked and an alert sent to the security team. 3. The solution must detect and prevent data exfiltration from endpoints by monitoring copy/paste and print actions on sensitive data. 4. All data security events must be centralized in Microsoft Sentinel for correlation and investigation. 5. The solution must comply with regulatory requirements that mandate data retention and eDiscovery capabilities.
You need to design the data security solution. Which combination of Microsoft security components should you use?
Microsoft Intune and Microsoft Entra ID
Why wrong: Missing data classification and DLP.
Microsoft Defender for Endpoint and Microsoft Sentinel
Why wrong: Missing data classification and eDiscovery.
Microsoft Defender for Cloud Apps and Microsoft Entra ID
Why wrong: Missing endpoint DLP and eDiscovery.
Microsoft Purview Information Protection, Microsoft Purview DLP, and Microsoft Purview eDiscovery
Covers all requirements.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Purview Information Protection, Microsoft Purview DLP, and Microsoft Purview eDiscovery
Option D is correct. Microsoft Purview Information Protection auto-labeling policies meet requirement 1. DLP policies in Purview block sharing and alert (requirement 2). Endpoint DLP in Purview monitors copy/paste/print (requirement 3). Purview audit logs are ingested into Microsoft Sentinel (requirement 4). Microsoft Purview eDiscovery and retention policies meet requirement 5. Option A is wrong because Microsoft Defender for Cloud Apps does not provide endpoint DLP or eDiscovery. Option B is wrong because Microsoft Intune does not provide DLP or eDiscovery. Option C is wrong because Microsoft Defender for Endpoint focuses on endpoint protection, not data classification or eDiscovery.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Microsoft Intune and Microsoft Entra ID
Why it's wrong here
Missing data classification and DLP.
Microsoft Defender for Endpoint and Microsoft Sentinel
Why it's wrong here
Missing data classification and eDiscovery.
Microsoft Defender for Cloud Apps and Microsoft Entra ID
Why it's wrong here
Missing endpoint DLP and eDiscovery.
Microsoft Purview Information Protection, Microsoft Purview DLP, and Microsoft Purview eDiscovery
Why this is correct
Covers all requirements.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SC-100 NAT questions on configuration and troubleshooting.
