AZ-301 Data & Storage Architecture 2

Question 1

A data architect needs to design a solution for ingesting, storing, and analyzing large volumes of data from multiple sources with both batch and real-time processing capabilities. Which Azure service provides this unified analytics platform?

Accepted Answer

Azure Synapse Analytics

Answer

Azure Synapse Analytics is a unified analytics platform that integrates big data and data warehousing with both batch processing and real-time analytics in a single service.

Question 2

An architect must design a solution where Azure Cosmos DB consistency needs to balance between strong consistency for reads and high write throughput globally. Which consistency level provides linearizability with lowest write latency tradeoff?

Accepted Answer

Bounded Staleness

Answer

Bounded Staleness guarantees reads lag writes by at most K versions or T time interval, providing strong ordering guarantees with better write throughput than Strong consistency.

Question 3

A company needs to implement a hot path and cold path architecture (lambda architecture) for IoT data on Azure. Which combination of services best represents this pattern?

Accepted Answer

Event Hubs + Stream Analytics (hot) and Data Factory + Synapse (cold)

Answer

Event Hubs with Stream Analytics handles the real-time hot path while Data Factory with Synapse Analytics processes historical batch data in the cold path of a lambda architecture.

Question 4

An architect needs to choose between Azure Blob Storage and Azure Files for a scenario where multiple Azure VMs running Windows need to access a shared file system via SMB protocol. Which service is appropriate?

Accepted Answer

Azure Files

Answer

Azure Files provides fully managed file shares accessible via SMB and NFS protocols, suitable for shared file system access across multiple Azure VMs.

Question 5

A company wants to implement geo-redundant storage for their Azure SQL Database to ensure data is replicated to a paired region for disaster recovery with an RPO of less than 5 seconds. Which feature should be configured?

Accepted Answer

Azure SQL Database active geo-replication

Answer

Azure SQL Database active geo-replication creates up to 4 readable secondary replicas in paired or other regions with asynchronous replication achieving RPO typically under 5 seconds.
