A company is developing a real-time multiplayer game that uses UDP for communications between the client and servers In an Auto Scaling group Spikes in demand are anticipated during the day, so the game server platform must adapt accordingly Developers want to store gamer scores and other non-relational data in a database solution that will scale without intervention
Which solution should a solutions architect recommend?

1. A. Use Amazon Route 53 for traffic distribution and Amazon Aurora Serverless for data storage
2. B. Use a Network Load Balancer for traffic distribution and Amazon DynamoDB on-demand for data storage
3. C. Use a Network Load Balancer for traffic distribution and Amazon Aurora Global Database for data storage
4. D. Use an Application Load Balancer for traffic distribution and Amazon DynamoDB global tables for data storage

Correct Answer: B

A company has an on-premises application that generates a large amount of time-sensitive data that is backed up to Amazon S3. The application has grown and there are user complaints about internet bandwidth limitations. A solutions architect needs to design a long-term solution that allows for both timely backups to Amazon S3 and with minimal impact on internet connectivity for internal users.
Which solution meets these requirements?

1. A. Establish AWS VPN connections and proxy all traffic through a VPC gateway endpoint
2. B. Establish a new AWS Direct Connect connection and direct backup traffic through this new connection.
3. C. Order daily AWS Snowball devices Load the data onto the Snowball devices and return the devices to AWS each day.
4. D. Submit a support ticket through the AWS Management Console Request the removal of S3 service limits from the account.

Correct Answer: B

A company receives 10 TB of instrumentation data each day from several machines located at a single factory. The data consists of JSON files stored on a storage area network (SAN) in an on-premises data center located within the factory. The company wants to send this data to Amazon S3 where it can be accessed by several additional systems that provide critical near-real-lime analytics. A secure transfer is important because the data is considered sensitive.
Which solution offers the MOST reliable data transfer?

1. A. AWS DataSync over public internet
2. B. AWS DataSync over AWS Direct Connect
3. C. AWS Database Migration Service (AWS DMS) over public internet
4. D. AWS Database Migration Service (AWS DMS) over AWS Direct Connect

Correct Answer: B
These are some of the main use cases for AWS DataSync: • Data migration – Move active datasets rapidly
over the network into Amazon S3, Amazon EFS, or FSx for Windows File Server. DataSync includes automatic encryption and data integrity validation to help make sure that your data arrives securely, intact, and ready to use.

A company's dynamic website is hosted using on-premises servers in the United States. The company is launching its product in Europe, and it wants to optimize site loading times for new European users. The site's backend must remain in the United States. The product is being launched in a few days, and an immediate solution is needed.
What should the solutions architect recommend?

1. A. Launch an Amazon EC2 instance in us-east-1 and migrate the site to it.
2. B. Move the website to Amazon S3. Use cross-Region replication between Regions.
3. C. Use Amazon CloudFront with a custom origin pointing to the on-premises servers.
4. D. Use an Amazon Route 53 geo-proximity routing policy pointing to on-premises servers.

Correct Answer: C
https://aws.amazon.com/pt/blogs/aws/amazon-cloudfront-support-for-custom-origins/
You can now create a CloudFront distribution using a custom origin. Each distribution will can point to an S3 or to a custom origin. This could be another storage service, or it could be something more interesting and more dynamic, such as an EC2 instance or even an Elastic Load Balancer

A company is experiencing sudden increases in demand. The company needs to provision large Amazon EC2 instances from an Amazon Machine image (AMI) The instances will run m an Auto Scaling group. The company needs a solution that provides minimum initialization latency to meet the demand.
Which solution meets these requirements?

1. A. Use the aws ec2 register-image command to create an AMI from a snapshot Use AWS Step Functions to replace the AMI in the Auto Scaling group
2. B. Enable Amazon Elastic Block Store (Amazon EBS) fast snapshot restore on a snapshot Provision an AMI by using the snapshot Replace the AMI m the Auto Scaling group with the new AMI
3. C. Enable AMI creation and define lifecycle rules in Amazon Data Lifecycle Manager (Amazon DLM) Create an AWS Lambda function that modifies the AMI in the Auto Scaling group
4. D. Use Amazon EventBridge (Amazon CloudWatch Events) to invoke AWS Backup lifecycle policies that provision AMIs Configure Auto Scaling group capacity limits as an event source in EventBridge

Correct Answer: B
Enabling Amazon Elastic Block Store (Amazon EBS) fast snapshot restore on a snapshot allows you to quickly create a new Amazon Machine Image (AMI) from a snapshot, which can help reduce the initialization latency when provisioning new instances. Once the AMI is provisioned, you can replace the AMI in the Auto Scaling group with the new AMI. This will ensure that new instances are launched from the updated AMI and are able to meet the increased demand quickly.
