A company runs a three-tier application in a VPC. The web tier and database tier are in different Availability Zones. The application generates a high volume of traffic between the web and database tiers. The company wants to reduce data transfer costs. What should the company do?

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

Use a VPC endpoint for the database service.

Move the database tier to the same Availability Zone as the web tier.

Place the web and database tiers in the same subnet.

How can using a VPC endpoint help reduce data transfer costs?

It eliminates the need for internet gateways, reducing data transfer costs for traffic to AWS services.

It provides a free tier for all AWS services.

It increases the bandwidth available for data transfer.

It automatically compresses data transferred to AWS services.

A company needs a hybrid connection between its on-premises data center and AWS VPC. The workload is tolerant to internet latency and has variable bandwidth needs. Which option is the most cost-effective?

AWS Transit Gateway with Direct Connect

A company is designing a VPC for a three-tier application. To minimize costs, which subnetting strategy should the architect use?

Use the largest possible CIDR block to allow for future growth without redesign.

Use a single large subnet for all tiers to simplify routing and reduce the number of route tables.

Create a separate VPC for each tier to isolate traffic and reduce data transfer costs.

Create subnets sized to the expected number of resources, avoiding large unused IP ranges.

A company serves a large amount of static content (images, videos, and CSS files) from an EC2 instance behind an Application Load Balancer. Users are located globally, and the company wants to reduce data transfer costs and improve latency for these users. What should the company do?

Place the EC2 instance in multiple AWS Regions and use Route 53 latency-based routing.

Enable S3 Transfer Acceleration on the bucket and serve content from there.

Move the static content to Amazon S3 and serve it directly from S3.

Use Amazon CloudFront to distribute the static content globally.
