A company is building an online multiplayer game. The game communicates by using UDP, and low latency between the client and the backend is important. The backend is hosted on Amazon EC2 instances that can be deployed to multiple AWS Regions to meet demand. The company needs the game to be highly available so that users around the world can access the game at all times.
What should a solutions architect do to meet these requirements?
  • A. Deploy Amazon CloudFront to support the global traffic. Configure CloudFront with an origin group to allow access to EC2 instances in multiple Regions.
  • B. Deploy an Application Load Balancer in one Region to distribute traffic to EC2 instances in each Region that hosts the game's backend instances.
  • C. Deploy Amazon CloudFront to support an origin access identity (OAI). Associate the OAI with EC2 instances in each Region to support global traffic.
  • D. Deploy a Network Load Balancer in each Region to distribute the traffic. Use AWS Global Accelerator to route traffic to the correct Regional endpoint.

A company has no existing file share services. A new project requires access to file storage that is mountable as a drive for on-premises desktops. The file server must authenticate users to an Active Directory domain before they are able to access the storage.
Which service will allow Active Directory users to mount storage as a drive on their desktops?
  • A. Amazon S3 Glacier
  • B. AWS DataSync
  • C. AWS Snowball Edge
  • D. AWS Storage Gateway

A company is using an Application Load Balancer (ALB) to present its application to the internet. The company finds abnormal traffic access patterns across the application. A solutions architect needs to improve visibility into the infrastructure to help the company understand these abnormalities better.
What is the MOST operationally efficient solution that meets these requirements?
  • A. Create a table in Amazon Athena for AWS CloudTrail logs. Create a query for the relevant information.
  • B. Enable ALB access logging to Amazon S3. Create a table in Amazon Athena, and query the logs.
  • C. Enable ALB access logging to Amazon S3. Open each file in a text editor, and search each line for the relevant information.
  • D. Use Amazon EMR on a dedicated Amazon EC2 instance to directly query the ALB to acquire traffic access log information.

A company is designing a website that uses an Amazon S3 bucket to store static images. The company wants all future requests to have faster response times while reducing both latency and cost.
Which service configuration should a solutions architect recommend?
  • A. Deploy a NAT server in front of Amazon S3.
  • B. Deploy Amazon CloudFront in front of Amazon S3.
  • C. Deploy a Network Load Balancer in front of Amazon S3.
  • D. Configure Auto Scaling to automatically adjust the capacity of the website.

A disaster response team is using drones to collect images of recent storm damage. The response team's laptops lack the storage and compute capacity to transfer the images and process the data. While the team has Amazon EC2 instances for processing and Amazon S3 buckets for storage, network connectivity is intermittent and unreliable. The images need to be processed to evaluate the damage.
What should a solutions architect recommend?
  • A. Use AWS Snowball Edge devices to process and store the images.
  • B. Upload the images to Amazon Simple Queue Service (Amazon SQS) during intermittent connectivity to EC2 instances.
  • C. Configure Amazon Kinesis Data Firehose to create multiple delivery streams aimed separately at the S3 buckets for storage and the EC2 instances for processing the images.
  • D. Use AWS Storage Gateway pre-installed on a hardware appliance to cache the images locally for Amazon S3 to process the images when connectivity becomes available.

A company wants to host a web application on AWS that will communicate to a database within a VPC. The application should be highly available.
What should a solutions architect recommend?
  • A. Create two Amazon EC2 instances to host the web servers behind a load balancer, and then deploy the database on a large instance.
  • B. Deploy a load balancer in multiple Availability Zones with an Auto Scaling group for the web servers, and then deploy Amazon RDS in multiple Availability Zones.
  • C. Deploy a load balancer in the public subnet with an Auto Scaling group for the web servers, and then deploy the database on an Amazon EC2 instance in the private subnet.
  • D. Deploy two web servers with an Auto Scaling group, configure a domain that points to the two web servers, and then deploy a database architecture in multiple Availability Zones.

A company is migrating a large, mission-critical database to AWS. A solutions architect has decided to use an Amazon RDS for MySQL Multi-AZ DB instance that is deployed with 80,000 Provisioned IOPS for storage. The solutions architect is using AWS Database Migration Service (AWS DMS) to perform the data migration. The migration is taking longer than expected, and the company wants to speed up the process. The company's network team has ruled out bandwidth as a limiting factor.
Which actions should the solutions architect take to speed up the migration? (Choose two.)
  • A. Disable Multi-AZ on the target DB instance.
  • B. Create a new DMS instance that has a larger instance size.
  • C. Turn off logging on the target DB instance until the initial load is complete.
  • D. Restart the DMS task on a new DMS instance with transfer acceleration enabled.
  • E. Change the storage type on the target DB instance to Amazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp2).

A company is using an Amazon S3 bucket to store data uploaded by different departments from multiple locations. During an AWS Well-Architected review, the financial manager notices that 10 TB of S3 Standard storage data has been charged each month. However, in the AWS Management Console for Amazon S3, using the command to select all files and folders shows a total size of 5 TB.
What are the possible causes for this difference? (Choose two.)
  • A. Some files are stored with deduplication.
  • B. The S3 bucket has versioning enabled.
  • C. There are incomplete S3 multipart uploads.
  • D. The S3 bucker has AWS Key Management Service (AWS KMS) enabled.
  • E. The S3 bucket has Intelligent-Tiering enabled.
