- A
Assign RBAC roles to limit access and rely on Azure Activity Log.
Why wrong: Activity log shows operations but requires setup for alerts.
- B
Configure Azure Policy to audit storage account access.
Why wrong: Policy audits at resource level, not real-time.
- C
Enable diagnostic settings for the storage account, send logs to Log Analytics, and create an alert rule for 'StorageRead' failures.
Diagnostic logs capture detailed access, alerts can be set on specific conditions.
- D
Enable Azure Sentinel and connect storage logs.
Why wrong: Sentinel is powerful but overkill for simple alerting.
Question 163 of 851
How to Set Up Alerts for Unauthorized Access Attempts in ADLS Gen2
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. 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.
Your company uses Azure Data Lake Storage Gen2 as a data lake. You need to monitor for unauthorized access attempts and ensure compliance with regulatory requirements. You want to be alerted when someone attempts to access data without proper permissions. What should you configure?
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
✓
Enable diagnostic settings for the storage account, send logs to Log Analytics, and create an alert rule for 'StorageRead' failures.
Option C is correct because enabling diagnostic settings for the storage account and sending logs to Log Analytics allows you to create alert rules that trigger on 'StorageRead' failures, indicating unauthorized access attempts. Option A is incorrect because while RBAC roles limit access, the Azure Activity Log only records management plane operations, not data plane access such as read failures. Option B is incorrect because Azure Policy is for governance and compliance of resource configurations, not for monitoring and alerting on access events. Option D is incorrect because although Azure Sentinel could be used, it is a more complex SIEM solution; the question asks for what should be configured, and the simpler, direct approach is to use diagnostic settings with Log Analytics alerts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
