MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. 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.
A multinational company must comply with the General Data Protection Regulation (GDPR). They need to be able to search for and delete personal data of a user upon request (right to erasure). Which Microsoft Purview solution should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview eDiscovery (Premium)
Option C is correct because Microsoft Purview eDiscovery (Premium) allows searching for content across Microsoft 365 and can be used to facilitate data deletion. Option A is wrong because Audit (Standard) only logs activities. Option B is wrong because Communication Compliance monitors communications. Option D is wrong because Insider Risk Management identifies risky activities.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Microsoft Purview eDiscovery (Premium)
Why this is correct
eDiscovery Premium can search, collect, and export data, and supports deletion.
Related concept
Static NAT maps one inside address to one outside address.
✗
Microsoft Purview Audit (Standard)
Why it's wrong here
Audit logs provide records but not search and delete capabilities.
✗
Microsoft Purview Communication Compliance
Why it's wrong here
Communication Compliance is for policy violations, not data subject requests.
✗
Microsoft Purview Insider Risk Management
Why it's wrong here
Insider Risk Management is for security risks, not compliance with erasure requests.
Common exam traps
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.
Detailed technical explanation
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.
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
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. 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.
