How can Amazon CloudFront help reduce data transfer costs for a web application?

By providing a dedicated connection to the origin, lowering data transfer fees.

By caching content at edge locations, reducing the amount of data transferred from the origin.

By eliminating the need for an origin server, thus removing data transfer costs entirely.

By compressing all content automatically, reducing the size of data transferred.

What is a primary benefit of using CloudFront for content delivery in terms of cost optimization?

It automatically scales the origin infrastructure to handle traffic spikes.

It provides free SSL certificates, reducing security costs.

It reduces the need for multiple origin servers by serving content from edge locations.

It eliminates all data transfer costs for the application.

A company runs a microservices application on EC2 instances in a VPC. The microservices communicate with each other frequently. The company wants to reduce data transfer costs between the microservices. What should the company do?

Use a larger instance type for the microservices to reduce the number of requests.

Use VPC peering to connect the microservices.

Place all microservices in the same Availability Zone.

Use a transit gateway to connect the microservices.

A solutions architect is designing a network architecture for a new application. The primary goal is to minimize costs while still meeting the application's performance and security requirements. Which principle should the architect apply to achieve this goal?

Use the highest-bandwidth instance types for all components to ensure maximum performance.

Match network capacity and features to the actual workload requirements, avoiding over-provisioning.

Design the network to route traffic through multiple AWS regions to improve redundancy and reduce latency.

Place all resources in a single Availability Zone to eliminate data transfer costs between zones.

A company needs to provide outbound internet access to instances in a private subnet. The workload has low and predictable traffic. Which option is the most cost-effective?

An internet gateway attached to the VPC

A VPC endpoint for the internet

A NAT gateway in each Availability Zone

A NAT instance that you manage yourself
