A company needs to use AWS resources to expand capacity for a website hosted in an on-premises data center. The AWS resources will include load balancers, Auto Scaling, and Amazon EC2 instances that will access an on-premises database. Network connectivity has been established, but no traffic is going to the AWS environment. How should Amazon Route 53 be configured to distribute load to the AWS environment? (Select TWO.)

A company hosts a website using Amazon API Gateway on the front end. Recently, there has been heavy traffic on the website and the company wants to control access by allowing authenticated traffic only. How should the company limit access to authenticated users only? (Select TWO.)

A company wants to create an application that will transmit protected health information (PHI) to thousands of service consumers in different AWS accounts. The application servers will sit in private VPC subnets. The routing for the application must be fault tolerant. What should be done to meet these requirements?

A company needs to store data for 5 years. The company will need to have immediate and highly available access to the data at any point in time, but will not require frequent access. What lifecycle action should be taken to meet the requirements while reducing costs?

A company is developing a data lake solution in Amazon S3 to analyze large-scale datasets. The solution makes infrequent SQL queries only. In addition, the company wants to minimize infrastructure costs. Which AWS service should be used to meet these requirements?

A company plans to deploy a new application in AWS that reads and writes information to a database. The company wants to deploy the application in two different AWS Regions in an active-active configuration. The databases need to replicate to keep information in sync. What should be used to meet these requirements?

A Solutions Architect is designing a new architecture that will use an Amazon EC2 Auto Scaling group. Which of the following factors determine the health check grace period? (Select TWO.)

A company wants to improve latency by hosting images within a public Amazon S3 bucket fronted by an Amazon CloudFront distribution.
