AWS Certified Cloud Practitioner (CLF-C01)- How AWS Pricing Works – Part 3

The video tutorial provides an in-depth review of AWS pricing models, focusing on RDS, DynamoDB, CloudFront, and reserved instances. It explains the factors influencing costs, such as server time, database characteristics, and data transfer. The tutorial also covers DynamoDB's flexible pricing, CloudFront's content delivery pricing, and the benefits of reserved instances for cost savings. Key concepts include pay-as-you-go, volume discounts, and reservation models.

What is a key factor that affects RDS pricing on AWS?

• The type of operating system used

• The number of tables in the database

• The clock hours of server time

• The number of users accessing the database

How does DynamoDB simplify the management of database resources?

• By offering a fixed pricing model

• By allowing users to specify storage types

• By requiring manual scaling of resources

• By automatically scaling read and write capacities

What is a characteristic of DynamoDB's provisioned throughput pricing?

• It charges based on the number of tables

• It requires upfront payment for storage

• It charges based on read and write capacity units

• It offers a flat monthly rate

Which AWS service is ideal for applications needing consistent low latency?

• Amazon DynamoDB

• AWS Lambda

• Amazon S3

• Amazon RDS

What is a unique feature of DynamoDB's global tables?

Which factor does NOT influence CloudFront pricing?

• Data transfer out

• Request types

• Traffic distribution

• The number of EC2 instances

How does AWS charge for data transfer in CloudFront?

• Based on the type of content

• Based on the amount of data transferred out

• Based on the number of users

• Based on the number of requests

What is a benefit of using reserved instances in AWS?

• They offer a pay-as-you-go model
