AZ-304 Azure Application Architecture Design

Question 1

Which Azure service is best suited for implementing a serverless, event-driven architecture that responds to HTTP triggers without managing infrastructure?

Accepted Answer

Azure Functions

Answer

Azure Functions supports HTTP triggers and runs serverless code without managing infrastructure, making it ideal for event-driven architectures.

Question 2

A company is designing a microservices architecture requiring built-in service discovery, load balancing, and automated rollouts. Which Azure service best meets these requirements?

Accepted Answer

Azure Kubernetes Service (AKS)

Answer

AKS provides built-in service discovery, load balancing, automated rollouts, and self-healing capabilities essential for microservices architectures.

Question 3

An application must process messages in strict order with exactly-once delivery guarantees. Which Azure messaging service should be selected?

Accepted Answer

Azure Service Bus with sessions

Answer

Azure Service Bus with sessions ensures ordered, exactly-once delivery by binding related messages to a named session and processing them sequentially.

Question 4

A web application tier must scale horizontally without maintaining server-side session state. Which approach best enables this design?

Accepted Answer

Offload session state to Azure Cache for Redis

Answer

Offloading session state to Azure Cache for Redis makes the web tier stateless, allowing any instance to handle any request and enabling true horizontal scaling.

Question 5

Which cloud design pattern is specifically intended to prevent a failing component from causing cascading failures across a distributed system?

Accepted Answer

Circuit Breaker pattern

Answer

The Circuit Breaker pattern monitors failures and opens the circuit to stop calling a failing service, preventing cascading failures across the system.
