DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You have an Azure Data Lake Storage Gen2 account that stores sensitive customer data. You need to implement security controls to prevent data exfiltration by a malicious insider who has Contributor role access. Which Azure feature should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply an Azure Policy that denies data access from unapproved locations.
Azure Policy can enforce a deny effect on data access requests originating from unapproved locations, effectively preventing data exfiltration even if the user has Contributor role. This is a preventive control, not just monitoring. Option A (diagnostic settings) is detective only. Option B (removing Contributor role) might reduce permissions but does not prevent the insider from using their current role. Option C (network firewall rules) can be bypassed if the insider accesses from within the trusted network. Therefore, Azure Policy with location-based deny is the most effective prevention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable diagnostic settings to log all access to the storage account.
Why it's wrong here
Diagnostic settings provide monitoring but do not prevent exfiltration.
- ✗
Remove the Contributor role and assign a custom role with read-only permissions.
Why it's wrong here
The user already has Contributor; removing and reassigning may not prevent exfiltration if they still have read access.
- ✗
Configure network firewall rules to allow only trusted IP addresses.
Why it's wrong here
Firewall rules can be circumvented if the attacker uses an allowed IP.
- ✓
Apply an Azure Policy that denies data access from unapproved locations.
Why this is correct
Azure Policy can enforce network restrictions to prevent data exfiltration.
