AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. 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. A key principle to apply: azure Blob Storage stores unstructured object data like images and videos.. 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 company needs to store large amounts of unstructured data, such as images and videos, which will be accessed by multiple applications over the internet. The data must be highly durable and available. Which Azure storage service should they use?
Why wrong: Azure Files provides managed file shares using SMB protocol, not ideal for direct HTTP access to large unstructured data.
B
Azure Blob Storage
Blob Storage is optimized for storing massive amounts of unstructured object data, accessible via HTTP/HTTPS. It offers multiple redundancy options for durability.
C
Azure Queue Storage
Why wrong: Queue Storage is for storing messages for asynchronous processing, not for image or video files.
D
Azure Disk Storage
Why wrong: Disk Storage provides block-level storage for Azure VMs, not for direct HTTP access and not designed for storing images as objects.
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
Azure Blob Storage is designed for storing massive amounts of unstructured data, such as images and videos, and provides high durability (99.9999999999% with LRS) and availability through geo-replication options. It supports access via HTTP/HTTPS from any internet-connected application, making it ideal for this scenario.
Key principle: Azure Blob Storage stores unstructured object data like images and videos.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Files (a managed file share) with Blob Storage because both can store files, but Azure Files is for SMB/NFS-based shared access, not for large-scale unstructured data accessed via HTTP/HTTPS.
Detailed technical explanation
How to think about this question
Azure Blob Storage organizes data into containers, with each blob (object) having a unique URL and supporting REST APIs for access. It offers three access tiers (Hot, Cool, Archive) to optimize cost based on access frequency, and features like immutable storage and lifecycle management policies. In a real-world scenario, a media streaming platform would use Blob Storage to store video files and serve them via CDN integration for global low-latency access.
KKey Concepts to Remember
Azure Blob Storage stores unstructured object data like images and videos.
Data in Blob Storage is accessed via HTTP/HTTPS.
Blob Storage offers high durability and availability through redundancy options.
It is highly scalable, capable of storing petabytes of data.
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
Azure Blob Storage stores unstructured object data like images and videos.
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.
