AZ-301 Architecture Design & Integration 3

Question 1

An architect must design a solution where a legacy on-premises application communicates with Azure services without modification. The on-premises app uses SOAP/WCF. Which Azure service enables this hybrid connectivity?

Accepted Answer

Azure Relay

Answer

Azure Relay enables hybrid connectivity by allowing on-premises services to be exposed to the cloud without firewall changes using WCF relay bindings.

Question 2

When designing a multi-region active-active architecture on Azure, which configuration ensures that read and write operations are distributed across all regions with lowest latency?

Accepted Answer

Azure Cosmos DB with multi-region writes

Answer

Azure Cosmos DB with multi-region writes (multi-master) allows read and write operations from any region simultaneously with guaranteed low latency.

Question 3

A company's architecture requires connecting multiple Azure virtual networks across different regions with a hub-and-spoke topology. Which service simplifies this at scale with built-in routing?

Accepted Answer

Azure Virtual WAN

Answer

Azure Virtual WAN provides a unified networking-as-a-service hub for connecting VNets, branches, and remote users with built-in routing at scale.

Question 4

An architect is designing a solution that needs to cache frequently accessed data from Azure SQL Database to reduce latency and database load. Which caching strategy and service should be used?

Accepted Answer

Read-aside with Azure Cache for Redis

Answer

The cache-aside (read-aside) pattern with Azure Cache for Redis is the standard approach where the application checks the cache before querying the database.

Question 5

When designing an Azure architecture, an architect needs to ensure that all outbound internet traffic from a VNet passes through a centralized security appliance for inspection. Which approach achieves this?

Accepted Answer

Azure Firewall with forced tunneling

Answer

Azure Firewall with forced tunneling uses User Defined Routes to redirect all outbound traffic through the firewall for centralized inspection and filtering.
