The answer is that the data volume exceeds the workspace’s ingestion capacity, causing data truncation. This occurs because when Defender for Cloud Apps sends more logs than your Log Analytics workspace can process per minute, the ingestion pipeline throttles the data, truncating records mid-stream and marking them as malformed. On the SC-200 exam, this scenario tests your understanding that a healthy connector status only confirms network connectivity, not that data is being ingested correctly—a common trap where candidates assume the connector must be broken. The key distinction is that malformed data errors from throttling happen after the connector, while authentication or firewall issues would prevent any data from arriving. Memory tip: think of a healthy connector as a working pipe, but if you pour too much water through it, the pressure causes the water to splash out as malformed droplets.
SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. 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 Defender for Cloud Apps and Microsoft Sentinel. You notice that a large number of log entries from Defender for Cloud Apps are being dropped at ingestion due to 'malformed data' errors. The data connector shows a healthy status. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The data volume exceeds the workspace's ingestion capacity, causing data truncation.
Option A is correct because excessive data volume can cause throttling or truncation, leading to malformed data errors even if the connector appears healthy. Option B is wrong because an expired workspace key would cause authentication failures, not malformed data. Option C is wrong because a firewall block would prevent connectivity entirely. Option D is wrong because unsupported log types would result in schema errors, not malformed data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The log type is not supported by Sentinel.
Why it's wrong here
Unsupported types would be rejected with schema errors.
✗
The Log Analytics workspace key has expired.
Why it's wrong here
Expired keys cause authentication failures.
✓
The data volume exceeds the workspace's ingestion capacity, causing data truncation.
Why this is correct
Throttling can cause partial logs that are malformed.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The Defender for Cloud Apps connector is blocked by a firewall.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
