- A
BlobStorage, because it is optimized for blob data and can store logs efficiently.
Why wrong: BlobStorage accounts are limited to blob data and do not provide Azure Files shares or the broad feature set needed for this mixed workload.
- B
StorageV2 (general-purpose v2), because it supports blobs, Azure Files, lifecycle management, and modern network features.
General-purpose v2 is the correct choice because it supports both Blob storage and Azure Files, includes lifecycle management for blobs, and offers the current feature set expected for private endpoints and standard administration. It is the normal recommendation when you need multiple storage services in one account.
- C
FileStorage, because it is the best option when Azure Files is required.
Why wrong: FileStorage is specialized for premium Azure Files shares and does not fit a requirement that includes Blob containers and lifecycle policies in the same account.
- D
BlockBlobStorage, because it provides the highest performance for operational data.
Why wrong: BlockBlobStorage is designed for premium block blob workloads only and does not support Azure Files shares or the general-purpose feature mix in the requirement.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. 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 platform team wants one Azure storage account for application logs in Blob containers and a shared working directory for a Windows admin VM and a Linux automation VM. The account must support blob lifecycle rules, standard performance, and future private endpoint access. Which storage account kind should the administrator create?
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
StorageV2 (general-purpose v2), because it supports blobs, Azure Files, lifecycle management, and modern network features.
StorageV2 (general-purpose v2) is the correct choice because it supports Blob storage, Azure Files (required for the shared working directory), blob lifecycle management rules, and advanced networking features like private endpoints. It also provides standard performance, meeting all stated requirements. Other storage kinds lack either Azure Files support or lifecycle management capabilities.
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.
- ✗
BlobStorage, because it is optimized for blob data and can store logs efficiently.
Why it's wrong here
BlobStorage accounts are limited to blob data and do not provide Azure Files shares or the broad feature set needed for this mixed workload.
When this WOULD be correct
A question that asks for a storage account optimized solely for storing large amounts of unstructured blob data (e.g., backup archives or log data) with no need for file shares, lifecycle policies, or private endpoints would make BlobStorage correct.
- ✓
StorageV2 (general-purpose v2), because it supports blobs, Azure Files, lifecycle management, and modern network features.
Why this is correct
General-purpose v2 is the correct choice because it supports both Blob storage and Azure Files, includes lifecycle management for blobs, and offers the current feature set expected for private endpoints and standard administration. It is the normal recommendation when you need multiple storage services in one account.
Related concept

- ✗
FileStorage, because it is the best option when Azure Files is required.
Why it's wrong here
FileStorage is specialized for premium Azure Files shares and does not fit a requirement that includes Blob containers and lifecycle policies in the same account.
When this WOULD be correct
A question requiring a premium Azure Files share for high-performance file shares, with no need for blobs or lifecycle rules, and private endpoint access is acceptable.
- ✗
BlockBlobStorage, because it provides the highest performance for operational data.
Why it's wrong here
BlockBlobStorage is designed for premium block blob workloads only and does not support Azure Files shares or the general-purpose feature mix in the requirement.
When this WOULD be correct
A scenario requiring ultra-low latency for large-scale analytics or IoT telemetry where premium block blob performance is needed, and Azure Files, lifecycle management, and private endpoints are not required.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓StorageV2 (general-purpose v2), because it supports blobs, Azure Files, lifecycle management, and modern network features.Correct answer▾
Why this is correct
General-purpose v2 is the correct choice because it supports both Blob storage and Azure Files, includes lifecycle management for blobs, and offers the current feature set expected for private endpoints and standard administration. It is the normal recommendation when you need multiple storage services in one account.
✗BlobStorage, because it is optimized for blob data and can store logs efficiently.Wrong answer — click to see why▾
Why this is wrong here
BlobStorage accounts do not support Azure Files, which is required for the shared working directory accessible by both Windows and Linux VMs. They also lack lifecycle management and private endpoint support.
★ When this WOULD be the correct answer
A question that asks for a storage account optimized solely for storing large amounts of unstructured blob data (e.g., backup archives or log data) with no need for file shares, lifecycle policies, or private endpoints would make BlobStorage correct.
Why candidates choose this
Candidates may focus on the 'application logs in Blob containers' requirement and assume BlobStorage is sufficient, overlooking the need for Azure Files and lifecycle management.
✗FileStorage, because it is the best option when Azure Files is required.Wrong answer — click to see why▾
Why this is wrong here
FileStorage is a premium-only account kind for Azure Files, lacking blob support and lifecycle management, and does not meet the 'standard performance' requirement.
★ When this WOULD be the correct answer
A question requiring a premium Azure Files share for high-performance file shares, with no need for blobs or lifecycle rules, and private endpoint access is acceptable.
Why candidates choose this
Candidates see 'shared working directory' and 'Azure Files' and assume FileStorage is the best fit, overlooking the need for blob support and standard performance tier.
✗BlockBlobStorage, because it provides the highest performance for operational data.Wrong answer — click to see why▾
Why this is wrong here
BlockBlobStorage is designed for high-throughput workloads with premium performance and does not support Azure Files, lifecycle management, or standard performance tier, all of which are required in this scenario.
★ When this WOULD be the correct answer
A scenario requiring ultra-low latency for large-scale analytics or IoT telemetry where premium block blob performance is needed, and Azure Files, lifecycle management, and private endpoints are not required.
Why candidates choose this
Candidates may confuse 'block blobs' with 'blob storage' and assume higher performance is always better, overlooking the specific requirements for Azure Files and lifecycle management.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose BlobStorage because they focus on 'blob lifecycle rules' and 'logs,' forgetting that the shared working directory requires Azure Files, which BlobStorage does not support.
Detailed technical explanation
How to think about this question
Under the hood, StorageV2 accounts unify Blob, File, Queue, and Table storage under a single REST API endpoint, enabling lifecycle policies that automatically tier or delete blobs based on age. Private endpoints use Azure Private Link to assign a private IP from a virtual network, eliminating public internet exposure. In a real-world scenario, a platform team might need to enforce data retention policies on logs via lifecycle rules while allowing both Windows and Linux VMs to access the same Azure File share using SMB 3.0 or NFS, which only StorageV2 supports at standard performance.
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.
