Question 1:
Which of the following services best enables decoupling of application components in the AWS ecosystem?
A. Amazon RDS
B. AWS Lambda
C. Amazon S3
D. Amazon SQS
Correct Answer: D. Amazon SQS
Explanation:
Amazon Simple Queue Service (Amazon SQS) is designed specifically to decouple application components. In the AWS SAA C03 certification, understanding how to build loosely coupled architectures is critical. Amazon SQS allows different microservices or components of an application to communicate via messages without being tightly integrated. For example, a frontend web application can send order requests to a queue, which are then processed asynchronously by a backend worker service. DumpsArena’s AWS SAA C03 dumps provide real-world examples and explanations of how services like SQS are used to increase system resilience, making it easier for candidates to grasp decoupled design principles.
Question 2:
A Solutions Architect must design a highly available web application using stateless web servers. Which AWS service combination meets this requirement most effectively?
A. EC2 Auto Scaling + Application Load Balancer
B. AWS Lambda + Amazon CloudFront
C. Amazon RDS Multi-AZ + Route 53
D. AWS Elastic Beanstalk + Amazon Aurora
Correct Answer: A. EC2 Auto Scaling + Application Load Balancer
Explanation:
The correct architecture for a stateless and highly available web application involves EC2 instances that are automatically scaled and distributed using an Application Load Balancer (ALB). This ensures load distribution and high availability. In the AWS SAA C03 exam, such scenarios are commonly tested to assess architectural decision-making. ALB manages traffic across multiple instances, while EC2 Auto Scaling ensures that demand fluctuations are handled automatically. DumpsArena’s AWS SAA C03 dumps explain how to deploy such architectures and help learners understand the configurations that support elasticity, fault tolerance, and availability—all key exam domains.
Question 3:
Which of the following AWS services provides a serverless computing environment?
A. Amazon EC2
B. AWS Lambda
C. Amazon ECS
D. Amazon Lightsail
Correct Answer: B. AWS Lambda
Explanation:
AWS Lambda is the quintessential serverless service in AWS, allowing developers to run code without provisioning or managing servers. You only pay for the compute time consumed during code execution. In the AWS SAA C03 certification exam, serverless technologies are a core area of focus, particularly for building cost-effective and scalable applications. DumpsArena helps candidates recognize use cases for Lambda and how it integrates with other services like API Gateway, DynamoDB, and S3. Their study resources offer scenario-based questions that improve a candidate’s ability to identify when and where to use Lambda in a cloud-native architecture.
Question 4:
Which AWS feature enables automated recovery of EC2 instances in case of failure?
A. EC2 Placement Groups
B. EC2 Auto Scaling
C. EC2 Recovery Option
D. EC2 Spot Instances
Correct Answer: C. EC2 Recovery Option
Explanation:
The EC2 Recovery Option is designed to detect instance failures and automatically recover the instance on the same hardware. This feature is particularly useful for applications that require high availability without complete automation through scaling groups. While EC2 Auto Scaling can also help with instance health and availability, the Recovery Option specifically addresses hardware or software failures for a single instance. DumpsArena’s AWS SAA C03 exam preparation materials include case-based questions on EC2 configurations, helping candidates understand subtle differences between recovery, failover, and scaling strategies. This is key to choosing the best option under exam conditions.
Question 5:
You need to securely store and manage encryption keys for data at rest in AWS. Which service should you use?
A. Amazon S3
B. AWS Secrets Manager
C. AWS Key Management Service (KMS)
D. AWS Certificate Manager
Correct Answer: C. AWS Key Management Service (KMS)
Explanation:
AWS Key Management Service (KMS) allows users to create and control cryptographic keys used to encrypt data at rest and in transit. It integrates with almost every AWS service, including S3, EBS, and RDS, to provide envelope encryption using customer master keys (CMKs). In the AWS SAA C03 exam, understanding how to implement data protection and encryption strategies is crucial. DumpsArena’s exam dumps delve into scenarios involving KMS, helping learners differentiate it from other security services like Secrets Manager or Certificate Manager. The practice questions guide candidates in making the correct architectural choices when encryption is required by compliance or business logic.
