20+ practice questions focused on Develop for Azure storage — one of the most tested topics on the Microsoft Azure Developer Associate AZ-204 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Develop for Azure storage PracticeYou are developing an IoT solution that stores device metadata (device ID, location, firmware version, last seen timestamp) in Azure Table Storage. Each device has a unique DeviceId and a Timestamp. You need to design the PartitionKey and RowKey to optimize query performance for the following query: Retrieve all firmware versions for devices in a specific city that were last seen within the last 24 hours. The query must be efficient (partition scan minimized). Which key design is most appropriate?
Explanation: City as the PartitionKey groups all devices for a city in one partition. Use a zero-padded, fixed-length inverted timestamp such as (DateTime.MaxValue.Ticks - Timestamp.Ticks).ToString("D19") as the RowKey; this makes more recent timestamps sort as smaller RowKey values. To retrieve the last 24 hours efficiently, query the city partition for RowKey values between the inverted current timestamp (lower bound) and the inverted timestamp 24 hours ago (upper bound) — i.e., RowKey >= inverted(now) and RowKey <= inverted(now - 24h). Azure Table Storage can then perform a partitioned range scan instead of scanning all devices in the city.
Match each Azure Storage access tier to its description.
Explanation: Azure Blob Storage access tiers include Hot, Cool, Cold, and Archive. Hot is optimized for frequently accessed data and has the highest storage cost but the lowest access cost (Option A). Cool is optimized for infrequently accessed data stored for at least 30 days (Option C). Cold is optimized for infrequently accessed data stored for at least 90 days (Option E). Archive is optimized for rarely accessed data stored for at least 180 days (Option F). Therefore the correct options are A, C, E, and F.
Which TWO of the following are valid ways to authenticate to Azure Blob Storage from an application? (Choose two.)
Explanation: Storage account access keys provide full administrative access to the storage account, including Blob Storage. Applications can authenticate by including the key in the Authorization header using the SharedKey scheme, which HMAC-SHA256 signs the request. Shared Access Signatures (SAS) tokens provide delegated access to specific resources in a storage account with granular permissions and a defined validity period, making them ideal for granting limited access to clients without exposing the account key. Both are standard, documented methods for authenticating to Azure Blob Storage from an application.
Which THREE of the following are true about Azure Storage queues? (Choose three.)
Explanation: Azure Storage queue messages have a configurable time-to-live (TTL) with a maximum value of 7 days. Messages are limited to 64 KB in size. The visibility timeout feature allows a consumer to temporarily hide a message from other consumers while it is being processed, preventing duplicate processing.
Which TWO of the following are features of Azure Blob Storage lifecycle management? (Choose two.)
Explanation: Azure Blob Storage lifecycle management policies allow you to define rules that automatically delete blobs or move them between access tiers (Hot, Cool, Archive) after a specified number of days. This is commonly used to enforce data retention policies, optimize costs by moving less frequently accessed data to cooler tiers, or clean up temporary data without manual intervention.
