AWS Certified Solutions Architect Associate (SAA-C02) Exam Prep Course - SQS

The video tutorial provides an in-depth look at AWS's Simple Queue Service (SQS), focusing on its advantages for decoupling services and resources. It covers the creation of FIFO queues, explaining the importance of naming conventions and the differences between standard and FIFO queues. The tutorial also explores queue settings, such as visibility timeout, and demonstrates sending test messages. Additionally, it discusses programmatic message sending using AWS SDK and the integration of SQS with AWS Lambda for serverless computing. The video concludes with an introduction to the Simple Notification Service (SNS) and its role in AWS architecture.

What is one of the main advantages of using AWS SQS?

• It allows for tightly coupled services.

• It provides a graphical user interface.

• It helps in loosely decoupling services and resources.

• It offers unlimited storage capacity.

What must you do before creating a FIFO queue in AWS SQS?

• Choose a different AWS region.

• End the queue name with the .FIFO extension.

• Enable content-based deduplication.

• Set the default visibility timeout to zero.

Which type of queue in AWS SQS supports nearly unlimited transactions per second?

• Batch queue

• Priority queue

• Standard queue

• FIFO queue

What is a key feature of the FIFO queue in AWS SQS?

• It has a higher transaction limit than the standard queue.

• It requires no deduplication ID.

• It supports exactly-once processing.

• Messages can be delivered out of order.

What is the purpose of the default visibility timeout in a FIFO queue?

• To ensure messages are processed by multiple instances simultaneously.

• To make messages visible to all consumers immediately.

• To delete messages after a certain period.

• To make a message invisible to other consumers for a set time after being picked up.

What is required when sending a test message in a FIFO queue?

• A unique message group ID and deduplication ID.

• Content-based deduplication enabled.

• A minimum of two attributes.

• A specific AWS region.

How are messages typically sent to the SQS service?

• Through the AWS Management Console.

• Programmatically using SDKs.

• Via email notifications.

• Using the AWS CLI only.

What is a benefit of integrating AWS SQS with AWS Lambda?

• It requires a dedicated server.

• It requires manual scaling of EC2 instances.

• It limits the compute resources available.

• It eliminates the need for virtual machines.

What is the Simple Notification Service (SNS) primarily used for?

• Storing large amounts of data.

• Managing EC2 instances.

• Sending alerts and notifications.

• Running serverless applications.

Which AWS service is often used alongside SQS for serverless computing?

• AWS S3

• AWS Lambda

• AWS RDS

• AWS EC2
