The correct answer is to associate the new Log Analytics workspace with an Azure Key Vault containing the customer-managed key before ingesting any data. This is because customer-managed keys for Sentinel are configured at the Log Analytics workspace level, not per table or connector, and encryption must be applied before data is written to ensure all data at rest is protected from the start. On the SC-200 exam, this concept tests your understanding that CMK is a workspace-wide setting, not something a data connector or individual table can enforce—a common trap is assuming you can apply encryption retroactively or per table. Remember the key principle: CMK must be set before ingestion, or you’ll have to re-ingest data to encrypt it. A helpful memory tip is “CMK before the data hits the disk.”
SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
You have a Microsoft Sentinel workspace that uses Customer-Managed Keys (CMK). A security audit requires that all data at rest be encrypted with the CMK. You recently onboarded a new data connector that sends logs to a Log Analytics workspace in a different region. You need to ensure the new workspace uses CMK. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Associate the new Log Analytics workspace with an Azure Key Vault containing the CMK before ingesting data.
Option D is correct because CMK must be configured at the Log Analytics workspace level before ingestion. Option A is wrong because CMK is per workspace, not per table. Option B is wrong because the connector itself doesn't handle encryption. Option C is wrong because CMK is set at workspace creation or later via Azure Policy.
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.
✓
Associate the new Log Analytics workspace with an Azure Key Vault containing the CMK before ingesting data.
Why this is correct
CMK association must be done before data ingestion.
Related concept
Read the scenario before looking for a memorised answer.
✗
Update the data connector settings to enable CMK at the source.
Why it's wrong here
Data connectors don't have CMK settings.
✗
Use Azure Policy to enforce CMK on the new workspace.
Why it's wrong here
Azure Policy can enforce but you need to configure the workspace first.
✗
Configure CMK on the new workspace's tables individually.
Why it's wrong here
CMK is configured at the workspace level, not table level.
Common exam traps
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.
