- A
Storage account audit logs (e.g., StorageReadKey, GetBlob)
These logs record data access operations on blobs, critical for detecting exfiltration.
- B
Azure Activity log for storage account write operations
Activity log includes audit events for management operations like listing storage account keys, which may indicate data exfiltration.

Azure AD sign-in logs
Why wrong: Sign-in logs show user authentication, but not direct data access to storage.

Why wrong: Key Vault logs show key access but not storage data operations.
AZ-500 Manage identity and access Practice Question
This AZ-500 practice question tests your understanding of manage identity and access. 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.
A security team wants to use Microsoft Sentinel to detect potential data exfiltration events from Azure Blob Storage. Which two logs should they ingest to best identify unauthorized read access and data transfer activities? (Choose two.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
Storage account audit logs (e.g., StorageReadKey, GetBlob)
Option A is correct because Storage account audit logs (e.g., StorageReadKey, GetBlob) capture detailed data-plane operations, including read access to blobs and keys, which directly indicates potential data exfiltration. Option B is correct because the Azure Activity log for storage account write operations records management-plane events like storage account key regeneration, which can be used to bypass existing access controls and exfiltrate data. Together, these logs provide visibility into both the data access and the administrative actions that could enable exfiltration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure AD sign-in logs with storage-specific audit logs, mistakenly thinking authentication logs alone can detect data exfiltration, when in fact they lack the data-plane operation details needed to identify unauthorized read or transfer activities.
Trap categories for this question
Command / output trap
Sign-in logs show user authentication, but not direct data access to storage.
Detailed technical explanation
How to think about this question
Storage account audit logs (Diagnostic Settings) capture data-plane operations like GetBlob, PutBlob, and StorageReadKey at the REST API level, which are essential for identifying unauthorized reads. The Azure Activity log captures management-plane operations such as ListStorageAccountKeys or RegenerateKey, which can be used to obtain account keys and then exfiltrate data via anonymous or key-based access. In a real-world scenario, an attacker might regenerate a storage account key (Activity log) and then use that key to read all blobs (Storage audit logs), making both logs critical for a complete detection chain.
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.
TExam Day Tips
- 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.
