A company uses Amazon EC2 instances and AWS Lambda functions to run its application. The company has VPCs with public subnets and private subnets in its AWS account. The EC2 instances run in a private subnet in one of the VPCs. The Lambda functions need direct network access to the EC2 instances for the application to work.

The application will run for at least 1 year. The company expects the number of Lambda functions that the application uses to increase during that time. The company wants to maximize its savings on all application resources and to keep network latency between the services low.

Which solution will meet these requirements?

Purchase on an EC2 instance Savings Plan. Optimize the Lambda functions duration and memory usage and the number of invocations. Connect the Lambda functions to the private subnet that contains the EC2 instances.

A company deploys an appliation on five Amazon EC2 instances. An Applicatin Load Balancer (ALB) distributes traffic to the instances by using a target group. The average CPU usage on each of the insatances is below 10% most of the time. With occasional surges to 65%.

A solution architect needs to implement a solution to automate the scalability of the application. The solution must optimize the cost of the architecture and must ensure that the application has enough CPU resources when surges occur. Which solution will meet these requirements?

Create an Amazon CloudWatch alarm that enters the ALARM state when the CPUUtilization metric is less than 20%. Create an AWS Lambda function that the CloudWatch alarm invokes to terminate one of the EC2 instances in the ALB target group.

A company is hosting a three-tier ecommerce application in the AWS Cloud. The company hosts the website on Amazon S3 and integrates the website with an API that handles sales requests. The company hosts the API on three Amazon EC2 instances behind an Application Load Balancer (ALB).

The API consists of static and dynamic front-end content along with backend workers that process sales requests asynchronously. The company is expecting a significant and sudden increase in the number of sales requests during events for the launch of new products What should a solutions architect recommend to ensure that all the requests are processed successfully?

Add an Amazon CloudFront distribution for the dynamic content. Increase the number of EC2 instances to handle the increase in traffic.

Add an Amazon CloudFront distribution for the static content. Add an Amazon Simple Queue Service (Amazon SOS) queue to receive requests from the website for later processing by the EC2 instances.
Suggested answer: B

Explanation:

This option is the most efficient because it uses Amazon CloudFront, which is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users1. It also uses a CloudFront distribution for the static content, which reduces the load on the EC2 instances and improves the performance and availability of the website. It also uses an Auto Scaling group to launch new instances based on network traffic, which automatically adjusts the compute capacity of your EC2 instances based on load or a schedule2. This solution meets the requirement of ensuring that all the requests are processed successfully during events for the launch of new products. Option A is less efficient because it uses a CloudFront distribution for the dynamic content, which is not necessary as the dynamic content is already handled by the API on the EC2 instances. It also increases the number of EC2 instances to handle the increase in traffic, which could incur higher costs and complexity than using an Auto Scaling group. Option C is less efficient because it uses an Amazon ElastiCache instance in front of the ALB to reduce traffic for the API to handle, which is a way to provide

A company's web application consists o( an Amazon API Gateway API in front of an AWS Lambda function and an Amazon DynamoDB database. The Lambda function handles the business logic, and the DynamoDB table hosts the dat a. The application uses Amazon Cognito user pools to identify the individual users of the application.

A solutions architect needs to update the application so that only users who have a subscription can access premium content.

Implement API usage plans and API keys to limit the access of users who do not have a subscription.
Suggested answer: D

Explanation:

This option is the most efficient because it uses API usage plans and API keys, which are features of Amazon API Gateway that allow you to control who can access your API and how much and how fast they can access it1. It also implements API usage plans and API keys to limit the access of users who do not have a subscription, which enables you to create different tiers of access for your API and charge users accordingly. This solution meets the requirement of updating the application so that only users who have a subscription can access premium content. Option A is less efficient because it uses API caching and throttling on the API Gateway API, which are features of Amazon API Gateway that allow you to improve the performance and availability of your API and protect your backend systems from traffic spikes2. However, this does not provide a way to limit the access of users who do not have a subscription. Option B is less efficient because it uses AWS WAF on the API Gateway API, which is a web application firewall service that helps protect your web applications or APIs against common web exploits that may affect availability, compromise security, or consume excessive resources3. However, this does not provide a way to limit the access of users who do not have a subscription. Option C is less efficient because it uses fine-grained IAM permissions to the premium content in the DynamoDB table, which are permissions that allow you to control access to specific items or attributes within a table4
