The answer is Azure Blob Storage with geo-redundant storage (GRS). This combination is correct because Azure Blob Storage natively handles large binary files up to 4.7 TB per blob, easily accommodating your 100 GB requirement, while GRS replicates your data to a paired secondary region, ensuring low-latency access from multiple geographic regions by serving reads from the nearest endpoint. On the AZ-204 exam, this scenario tests your understanding of storage redundancy options and blob capabilities—a common trap is choosing locally redundant storage (LRS) for cost savings, but that fails the multi-region access requirement. Remember that GRS provides both durability and geo-distributed read access, whereas read-access geo-redundant storage (RA-GRS) adds read-only access to the secondary region for even lower latency. Memory tip: think "Big Blobs Go Global" to link large files, Blob Storage, and GRS.
AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure 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.
You need to store and retrieve large binary files (up to 100 GB each) with low latency. The files will be accessed by multiple geographic regions. Which Azure storage solution should you recommend?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Blob Storage with geo-redundant storage (GRS).
Azure Blob Storage is designed for storing large binary objects (up to 4.7 TB per blob) and offers low-latency access via HTTP/HTTPS. Geo-redundant storage (GRS) replicates data to a paired secondary region, providing durability and availability for multi-region access. This combination meets the requirements for large files (up to 100 GB) and low-latency retrieval from multiple geographic regions.
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.
✗
Azure Queue Storage with messages.
Why it's wrong here
Azure Queue Storage is for messaging, not binary file storage.
✗
Azure Files with Azure File Sync.
Why it's wrong here
Azure Files supports SMB shares, not optimized for large binary files.
✓
Azure Blob Storage with geo-redundant storage (GRS).
Why this is correct
Azure Blob Storage is designed for large binary objects and supports geo-replication.

✗
Azure SQL Database with file tables.
Why it's wrong here
Azure SQL Database is for structured data.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Azure Files (SMB shares) with Blob Storage for large binary files, not realizing that Azure Files has a 1 TB file size limit and is optimized for shared file access, not for high-throughput blob storage with geo-replication.
Detailed technical explanation
How to think about this question
Azure Blob Storage uses a flat namespace with containers and blobs, supporting block blobs for large files (up to 4.7 TB) with parallel uploads via PutBlock and PutBlockList. GRS ensures synchronous replication within the primary region and asynchronous replication to a secondary region, providing a recovery point objective (RPO) of 15 minutes. For multi-region low-latency access, consider using read-access geo-redundant storage (RA-GRS) to allow reads from the secondary region, or Azure Content Delivery Network (CDN) for edge caching.

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.
