- A
Enable Microsoft Defender for Storage and configure malware scanning
Defender for Storage includes malware scanning that automatically scans newly uploaded blobs and can quarantine them in a separate container.
- B
Deploy Microsoft Sentinel and create an analytics rule to detect malware from storage logs
Why wrong: Sentinel can detect threats based on logs but does not perform active malware scanning of blob content.
- C
Create an Azure Policy to deny storage accounts without encryption
Why wrong: Azure Policy enforces compliance rules but does not scan for malware.
- D
Enable Azure Firewall and configure application rules to inspect HTTPS traffic
Why wrong: Azure Firewall does not inspect blob content for malware; it only filters based on FQDN and network rules.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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.
Your company stores sensitive documents in Azure Blob Storage. You need to implement a solution that automatically scans uploaded blobs for malware and quarantines any infected files. The solution must minimize administrative overhead and integrate with Azure Security Center. What should you use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 Microsoft Defender for Storage and configure malware scanning
Option C is correct because Microsoft Defender for Storage provides built-in malware scanning for blobs, with automatic quarantine and integration with Security Center. Option A is wrong because Azure Firewall is for network traffic filtering, not content scanning. Option B is wrong because Microsoft Sentinel is a SIEM, not a malware scanner. Option D is wrong because Azure Policy can enforce rules but does not scan for malware.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Deploy Microsoft Sentinel and create an analytics rule to detect malware from storage logs
Why it's wrong here
Sentinel can detect threats based on logs but does not perform active malware scanning of blob content.
- ✗
Create an Azure Policy to deny storage accounts without encryption
Why it's wrong here
Azure Policy enforces compliance rules but does not scan for malware.

Why it's wrong here
Azure Firewall does not inspect blob content for malware; it only filters based on FQDN and network rules.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related AZ-500 ACL questions on filtering logic and placement.
