The answer is to create a custom sensitive info type using a regular expression. This is correct because Microsoft Purview allows you to define precise pattern-matching logic through regex, enabling you to detect employee IDs formatted exactly as 'EMP-XXXXX' where each X is a digit. A built-in sensitive info type would not match this custom format, a keyword dictionary alone lacks the structural pattern, and exact data match requires a hash-based reference dataset rather than a pattern definition. On the MS-102 exam, this question tests your understanding of how to tailor data classification rules to specific organizational formats, often appearing as a scenario where you must choose between regex, keyword lists, or exact data match. A common trap is selecting a keyword dictionary because it seems simpler, but regex is the only option that enforces the exact digit count and hyphen placement. Memory tip: think of regex as the pattern sculptor—it carves out the exact shape of your data, while dictionaries just list possible words.
MS-102 Manage compliance by using Microsoft Purview Practice Question
This MS-102 practice question tests your understanding of manage compliance by using microsoft purview. 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 uses Microsoft Purview to classify and protect data. You need to create a custom sensitive info type that detects employee IDs formatted as 'EMP-XXXXX' where X is a digit. Which approach should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a custom sensitive info type using a regular expression.
Option B is correct because you can create a custom sensitive info type using a regular expression pattern. Option A is wrong because the built-in type may not match exactly. Option C is wrong because the keyword dictionary can be used as an additional element, but the pattern is best defined by regex. Option D is wrong because exact data match requires a source of truth, not a pattern.
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.
✓
Create a custom sensitive info type using a regular expression.
Why this is correct
Custom sensitive info types can use regex patterns to detect specific formats.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use a keyword dictionary for the pattern.
Why it's wrong here
Keyword dictionaries are for lists of terms, not patterns.
✗
Use exact data match (EDM) based classification.
Why it's wrong here
EDM uses a database of exact values, not pattern matching.
✗
Use the built-in 'Employee ID' sensitive info type.
Why it's wrong here
The built-in type may not match the specific format.
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.
Trap categories for this question
Keyword trap
Keyword dictionaries are for lists of terms, not patterns.
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.
