A development team needs to host a website that will be accessed by other teams. The website contents consist of HTML, CSS, client-side JavaScript, and images. A Solutions Architect has been asked to recommend a solution for hosting the website. Which solution is the MOST cost-effective?

• Containerize the website and host it in AWS Fargate
• Create an Amazon S3 bucket and host the website there
• Deploy a web server on an Amazon EC2 instance to host the website
• Configure an Application Load Balancer with an AWS Lambda target

A website runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The website’s DNS records are hosted in Amazon Route 53 with the domain name pointing to the ALB. A solution is required for displaying a static error page if the website becomes unavailable. Which configuration should a solutions architect use to meet these requirements with the LEAST operational overhead?

• Create a Route 53 alias record for an Amazon CloudFront distribution and specify the ALB as the origin. Create custom error pages for the distribution
• Create a Route 53 active-passive failover configuration. Create a static website using an Amazon S3 bucket that hosts a static error page. Configure the static website as the passive record for failover
• Create a Route 53 weighted routing policy. Create a static website using an Amazon S3 bucket that hosts a static error page. Configure the record for the S3 static website with a weighting of zero. When an issue occurs increase the weighting
• Set up a Route 53 active-active configuration with the ALB and an Amazon EC2 instance hosting a static error page as endpoints. Route 53 will only send requests to the instance if the health checks fail for the ALB

A static website currently runs in a company’s on-premises data center. The company plan to migrate the website to AWS. The website must load quickly for global users and the solution must also be cost-effective. What should a solutions architect do to accomplish this?

• Copy the website content to an Amazon S3 bucket. Configure the bucket to serve static webpage content. Replicate the S3 bucket to multiple AWS Regions
• Copy the website content to an Amazon S3 bucket. Configure the bucket to serve static webpage content. Configure Amazon CloudFront with the S3 bucket as the origin
• Copy the website content to an Amazon EC2 instance. Configure Amazon Route 53 geolocation routing policies to select the closest origin
• Copy the website content to multiple Amazon EC2 instances in multiple AWS Regions. Configure AWS Route 53 geolocation routing policies to select the closest region

A website runs on a Microsoft Windows server in an on-premises data center. The web server is being migrated to Amazon EC2 Windows instances in multiple Availability Zones on AWS. The web server currently uses data stored in an on-premises network-attached storage (NAS) device. Which replacement to the NAS file share is MOST resilient and durable?

• Migrate the file share to Amazon EBS
• Migrate the file share to AWS Storage Gateway
• Migrate the file share to Amazon FSx for Windows File Server
• Migrate the file share to Amazon Elastic File System (Amazon EFS)

A company is planning a migration for a high performance computing (HPC) application and associated data from an on-premises data center to the AWS Cloud. The company uses tiered storage on premises with hot high-performance parallel storage to support the application during periodic runs of the application, and more economical cold storage to hold the data when the application is not actively running. Which combination of solutions should a solutions architect recommend to support the storage needs of the application? (Select TWO)

• Amazon S3 for cold data storage
• Amazon EFS for cold data storage
• Amazon S3 for high-performance parallel storage
• Amazon FSx for Lustre for high-performance parallel storage
• Amazon FSx for Windows for high-performance parallel storage

A company runs an internal browser-based application. The application runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales up to 20 instances during work hours, but scales down to 2 instances overnight. Staff are complaining that the application is very slow when the day begins, although it runs well by midmorning. How should the scaling be changed to address the staff complaints and keep costs to a minimum?

• Implement a scheduled action that sets the desired capacity to 20 shortly before the office opens
• Implement a step scaling action triggered at a lower CPU threshold, and decrease the cooldown period
• Implement a target tracking action triggered at a lower CPU threshold, and decrease the cooldown period
• Implement a scheduled action that sets the minimum and maximum capacity to 20 shortly before the office opens

A company has 500 TB of data in an on-premises file share that needs to be moved to Amazon S3 Glacier. The migration must not saturate the company’s low-bandwidth internet connection and the migration must be completed within a few weeks. What is the MOST cost-effective solution?

• Create an AWS Direct Connect connection and migrate the data straight into Amazon Glacier
• Order 7 AWS Snowball appliances and select an S3 Glacier vault as the destination. Create a bucket policy to enforce a VPC endpoint
• Use AWS Global Accelerator to accelerate upload and optimize usage of the available bandwidth
• Order 7 AWS Snowball appliances and select an Amazon S3 bucket as the destination. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier

A company has refactored a legacy application to run as two microservices using Amazon ECS. The application processes data in two parts and the second part of the process takes longer than the first. How can a solutions architect integrate the microservices and allow them to scale independently?

• Implement code in microservice 1 to send data to an Amazon S3 bucket. Use S3 event notifications to invoke microservice 2
• Implement code in microservice 1 to publish data to an Amazon SNS topic. Implement code in microservice 2 to subscribe to this topic
• Implement code in microservice 1 to send data to Amazon Kinesis Data Firehose. Implement code in microservice 2 to read from Kinesis Data Firehose
• Implement code in microservice 1 to send data to an Amazon SQS queue. Implement code in microservice 2 to process messages from the queue

A solutions architect has created a new AWS account and must secure AWS account root user access. Which combination of actions will accomplish this? (Select TWO)

• Ensure the root user uses a strong password
• Enable multi-factor authentication to the root user
• Store root user access keys in an encrypted Amazon S3 bucket
• Add the root user to a group containing administrative permissions
• Delete the root user account

An organization is creating a new storage solution and needs to ensure that Amazon S3 objects that are deleted are immediately restorable for up to 30 days. After 30 days the objects should be retained for a further 180 days and be restorable within 24 hours. The solution should be operationally simple and cost-effective. How can these requirements be achieved? (Select TWO)

• Enable object versioning on the Amazon S3 bucket that will contain the objects
• Create a lifecycle rule to transition non-current versions to GLACIER after 30 days, and then expire the objects after 180 days
• Enable multi-factor authentication (MFA) delete protection
• Enable cross-region replication (CRR) for the Amazon S3 bucket that will contain the objects
• Create a lifecycle rule to transition non-current versions to STANDARD_IA after 30 days, and then expire the objects after 180 days
