AWS Simple Queue Service (SQS) Overview

What is the benefit of using SQS for managing workloads?

• It allows for efficient handling of tasks that require concurrent processing.

• It provides a user-friendly interface for managing tasks.

• It eliminates the need for any task management.

• It guarantees the order of message delivery.

What is the primary function of AWS SQS?

• To enable web service applications to quickly and reliably queue messages.

• To store data in a relational database.

• To provide a content delivery network for static files.

• To manage user authentication and authorization.

What are the two types of queues in AWS SQS?

• First-in-first-out (FIFO) and Standard Queue

• Last-in-first-out (LIFO) and Standard Queue

• Priority Queue and Standard Queue

• Circular Queue and Standard Queue

What is the default retention period for messages in SQS?

• 1 day

• 4 days

• 7 days

• 14 days

What is a Standard Queue?

• A queue where messages are delivered randomly and may be delivered multiple times.

• A queue that guarantees messages are delivered in the order they are sent.

• A queue that only allows one message to be processed at a time.

• A queue that automatically deletes messages after they are read.

What is the command to pull messages from an SQS queue using AWS CLI?

• aws sqs receive-message --queue-url

• aws sqs get-message --queue-url

• aws sqs pull-message --queue-url

• aws sqs fetch-message --queue-url

What are dead-letter queues in Amazon SQS?

• Queues that capture messages that cannot be processed successfully after a certain number of attempts.

• Queues that store messages for later processing without any limit on attempts.

• Queues that automatically delete messages after a specified time period.

• Queues that prioritize messages based on their size and type.

What is the command to send a message to an SQS queue using AWS CLI?

• aws sqs send-message --queue-url --message-body .

• aws sqs post-message --queue-url --message-body .

• aws sqs send-msg --queue-url --message-body .

• aws sqs message-send --queue-url --message-body .

What is the purpose of message deduplication in FIFO queues?

• To ensure messages are processed in the order they are received.

• To prevent the same message from being processed more than once within a 5-minute window.

• To increase the throughput of message processing.

• To allow messages to be processed by multiple consumers simultaneously.

What is the maximum retention period for messages in SQS?

• 7 days

• 14 days

• 30 days

• 1 day
