AZ-305 Azure Storage and Data Architecture

Question 1

Your application needs to store petabytes of unstructured data with tiered access: frequently accessed data served quickly and archival data stored cheaply. Which Azure Storage configuration best meets this need?

Accepted Answer

Azure Blob Storage with Hot, Cool, and Archive tiers using lifecycle management policies

Answer

Azure Blob Storage lifecycle management policies automatically move data between Hot, Cool, Cold, and Archive tiers based on last-modified or last-accessed time.

Question 2

A database workload requires sub-millisecond disk latency with guaranteed IOPS for mission-critical OLTP. Which Azure Disk type should you choose?

Accepted Answer

Ultra Disk Managed Disks

Answer

Ultra Disks provide sub-millisecond latency and allow you to dynamically configure IOPS and throughput without detaching the disk.

Question 3

You need to design a shared file system for a legacy Windows application that requires SMB access from Azure VMs and on-premises servers simultaneously. Which solution is appropriate?

Accepted Answer

Azure Files with SMB shares

Answer

Azure Files provides fully managed SMB file shares accessible from both Azure VMs and on-premises via Azure File Sync or direct SMB over the internet.

Question 4

Your data engineering team needs a storage account that supports hierarchical namespace for big data analytics workloads using Apache Spark. Which storage type should you enable?

Accepted Answer

Azure Data Lake Storage Gen2 (ADLS Gen2) with hierarchical namespace enabled

Answer

Enabling the hierarchical namespace on an Azure Storage account creates ADLS Gen2, which provides directory semantics and atomic operations optimized for analytics engines.

Question 5

You need to ensure that a Storage account's data cannot be deleted or modified for 7 years to comply with financial regulations. Which feature should you configure?

Accepted Answer

Immutable storage with time-based retention policies (WORM)

Answer

Immutable Blob Storage with time-based retention (WORM) policies prevents any deletion or modification of blobs for the specified retention period.
