AZ-104 Implement and Manage Storage Practice Question
A development team needs a single Azure Storage account for blob containers, Azure Files shares, and blob lifecycle rules. The account must support standard performance and allow future use of access tiers. Which account kind should you create?
⚠ Common exam trap
Microsoft often tests the misconception that BlobStorage accounts are sufficient for mixed workloads, but they intentionally omit that BlobStorage cannot host Azure Files shares, making StorageV2 the only viable choice when both blob and file storage are required with lifecycle management.
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 because it supports blobs, Azure Files, lifecycle management, and access tiers.
StorageV2 (general-purpose v2) is the only account kind that supports blobs, Azure Files shares, lifecycle management policies, and all access tiers (hot, cool, archive) with standard performance. BlobStorage lacks Azure Files support, FileStorage is premium-only and does not support lifecycle rules, and BlockBlobStorage is premium-only and does not support Azure Files or lifecycle management.
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 blobs and supports lifecycle management.
Why it's wrong here
BlobStorage is a legacy blob-only account type that supports block and append blobs, along with hot/cool/archive access tiers and lifecycle management policies. However, it cannot create Azure Files file shares, queues, or tables, so it fails the requirement for a single storage account that hosts both blobs and Azure Files. This account type is optimized for blob workloads but is not a general-purpose account.
When this WOULD be correct
A question that asks for an account optimized for blob storage only, with lifecycle management and access tiers, but no requirement for Azure Files or other services.
- ✓
StorageV2 because it supports blobs, Azure Files, lifecycle management, and access tiers.
Why this is correct
StorageV2 is the correct choice because it is the general-purpose v2 account type. It supports blob containers, Azure Files shares, blob access tiers, lifecycle management rules, and the standard capabilities used in most Azure administration scenarios. It is also the recommended account type when a team wants one storage account for multiple storage services and operational features.
- ✗
FileStorage because it is designed for file shares and can also host blob lifecycle rules.
Why it's wrong here
FileStorage is a premium account type dedicated exclusively to Azure Files, delivering low-latency SMB and NFS file shares on SSD-backed hardware. It exposes no blob service endpoint, so you cannot store blob containers or apply blob lifecycle management rules to data in such an account. Therefore, it cannot satisfy a scenario that requires one storage account to serve both blob containers and file shares, despite being well-suited for file-heavy workloads.
When this WOULD be correct
When the question specifies a need for premium performance for Azure Files shares only, with no requirement for blobs or lifecycle management, and access tiers are not needed.
- ✗
BlockBlobStorage because it provides the best performance for lifecycle policies and file shares.
Why it's wrong here
BlockBlobStorage is a premium-performance account type limited to block blobs and append blobs, typically used for high-throughput ingestion or analytics scenarios. Although it supports lifecycle management policies on its blob content, it does not support Azure Files shares, which are mandatory for this single-account requirement. Its performance focus is on low-latency blob transactions rather than providing the multi-service general-purpose feature set needed to host blobs and files together.
When this WOULD be correct
You would choose BlockBlobStorage when the requirement is for a premium block blob storage account with high transaction rates and low latency, and there is no need for Azure Files, lifecycle management, or access tiers.
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.

✗BlobStorage because it is optimized for blobs and supports lifecycle management.Wrong answer — click to see why▾
Why this is wrong here
BlobStorage does not support Azure Files shares, which are required by the development team.
★ When this WOULD be the correct answer
A question that asks for an account optimized for blob storage only, with lifecycle management and access tiers, but no requirement for Azure Files or other services.
Why candidates choose this
Candidates see 'blob containers' and 'lifecycle rules' and assume BlobStorage is sufficient, overlooking the need for Azure Files support.
✗FileStorage because it is designed for file shares and can also host blob lifecycle rules.Wrong answer — click to see why▾
Why this is wrong here
FileStorage is a premium-only account kind designed for high-performance file shares and does not support blob containers, lifecycle management, or access tiers.
★ When this WOULD be the correct answer
When the question specifies a need for premium performance for Azure Files shares only, with no requirement for blobs or lifecycle management, and access tiers are not needed.
Why candidates choose this
Candidates may assume that because FileStorage is specialized for files, it can also handle blobs and lifecycle rules, or they confuse it with StorageV2's capabilities.
✗BlockBlobStorage because it provides the best performance for lifecycle policies and file shares.Wrong answer — click to see why▾
Why this is wrong here
BlockBlobStorage is a premium account kind optimized for block blobs with low latency, but it does not support Azure Files shares or standard performance tiers, and it lacks lifecycle management features.
★ When this WOULD be the correct answer
You would choose BlockBlobStorage when the requirement is for a premium block blob storage account with high transaction rates and low latency, and there is no need for Azure Files, lifecycle management, or access tiers.
Why candidates choose this
Candidates may think 'BlockBlobStorage' implies block blobs and performance, but they overlook that it does not support Azure Files, lifecycle rules, or standard performance tiers required in the question.

Same concept, more angles
3 more ways this is tested on AZ-104
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company wants a single storage account for blob containers, Azure Files shares, and blob lifecycle management rules. Which two statements about the required account are true? Select two.
easy- ✓ A.It should be a general-purpose v2 storage account.
- ✓ B.It can host both blob containers and Azure Files shares.
- C.It must be a premium block blob account.
- D.It cannot use lifecycle management on blobs.
- E.It can store only one type of Azure Storage data service at a time.
Why A: A general-purpose v2 (GPv2) storage account is required because it is the only account type that supports all Azure Storage data services—including blob containers and Azure Files—and also provides full support for blob lifecycle management policies. GPv2 accounts offer the lowest per-gigabyte storage prices for blobs and enable you to define rules to automatically tier or delete blobs based on age or other conditions.
Variation 2. An organization wants a single Azure storage account that can host blob containers, Azure Files shares, and lifecycle management rules for blob data. Which storage account kind should the administrator create?
medium- A.BlobStorage
- B.FileStorage
- ✓ C.General-purpose v2 (StorageV2)
- D.BlockBlobStorage
Why C: General-purpose v2 (StorageV2) is the only storage account kind that supports blobs, Azure Files, and lifecycle management rules for blob data. It provides a unified account for all Azure Storage data services, including blobs, files, queues, and tables, and it natively supports lifecycle management policies to automatically tier or delete blob data based on age or other conditions.
Variation 3. A development team needs one storage account to host blob containers, Azure Files shares, and blob lifecycle management rules. Which two statements about the account are correct? Select two.
easy- ✓ A.It should be a General-purpose v2 storage account.
- B.It must be a BlobStorage account.
- ✓ C.It can host both blob containers and Azure Files shares.
- D.It must use only zone-redundant storage to use lifecycle rules.
- E.It cannot use lifecycle management for blobs.
Why A: A General-purpose v2 (GPv2) storage account is required because it supports the latest storage features, including blob lifecycle management rules, blob containers, and Azure Files shares. GPv2 accounts provide the necessary REST API endpoints and management capabilities for lifecycle policies, which are not available in older account types like BlobStorage or General-purpose v1.
