Quick Answer
The answer is DataPlaneRequests, the diagnostic setting that must be enabled to audit all data plane operations in Azure Cosmos DB. This setting captures every read, write, delete, and query request sent directly to the database, providing a complete log of user and application interactions for compliance auditing. In contrast, QueryRuntimeStatistics only logs query execution metrics, MongoRequests is limited to MongoDB API calls, and PartitionKeyStatistics tracks storage distribution—none of which capture the full scope of data plane activity. On the Microsoft Cybersecurity Architect exam, this question tests your ability to distinguish between diagnostic logging categories, a common trap being to confuse operational logs with performance or API-specific logs. A reliable memory tip is to think of “DataPlaneRequests” as the “everything log” for data operations, while other settings are specialized subsets.
This SC-100 practice question tests your understanding of design security solutions for applications and data. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company uses Azure Cosmos DB with Microsoft Defender for Cloud to protect its NoSQL database. The security team wants to audit all data plane operations for compliance. Which diagnostic setting should they enable?
MongoRequests
Why wrong: This log captures MongoDB API requests only, not all data plane operations.
PartitionKeyStatistics
Why wrong: This log provides partition key statistics, not operational audits.
QueryRuntimeStatistics
Why wrong: This log tracks query execution statistics, not all data plane operations.
DataPlaneRequests
This log records all data plane operations including CRUD on items.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
DataPlaneRequests
Option C is correct because DataPlaneRequests logs contain all data plane operations. Option A is wrong because QueryRuntimeStatistics logs query execution stats, not operations. Option B is wrong because MongoRequests logs MongoDB operations only. Option D is wrong because PartitionKeyStatistics logs partition statistics.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
MongoRequests
Why it's wrong here
This log captures MongoDB API requests only, not all data plane operations.
PartitionKeyStatistics
Why it's wrong here
This log provides partition key statistics, not operational audits.
QueryRuntimeStatistics
Why it's wrong here
This log tracks query execution statistics, not all data plane operations.
DataPlaneRequests
Why this is correct
This log records all data plane operations including CRUD on items.

Common exam traps
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.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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. 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.
