A solutions architect must design a solution for a persistent database that is being migrated from on-premises to AWS. The database requires 64,000 IOPS according to the database administrator. If possible, the database administrator wants to use a single Amazon Elastic Block Store (Amazon EBS) volume to host the database instance.
Which solution effectively meets the database administrator's criteria?
  • A. Use an instance from the I3 I/O optimized family and leverage local ephemeral storage to achieve the IOPS requirement.
  • B. Create a Nitro-based Amazon EC2 instance with an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD (io1) volume attached. Configure the volume to have 64,000 IOPS.
  • C. Create and map an Amazon Elastic File System (Amazon EFS) volume to the database instance and use the volume to achieve the required IOPS for the database.
  • D. Provision two volumes and assign 32,000 IOPS to each. Create a logical volume at the operating system level that aggregates both volumes to achieve the IOPS requirements.

A company has global users accessing an application deployed in different AWS Regions, exposing public static IP addresses. The users are experiencing poor performance when accessing the application over the internet.
What should a solutions architect recommend to reduce internet latency?
  • A. Set up AWS Global Accelerator and add endpoints.
  • B. Set up AWS Direct Connect locations in multiple Regions.
  • C. Set up an Amazon CloudFront distribution to access an application.
  • D. Set up an Amazon Route 53 geoproximity routing policy to route traffic.

A company recently deployed a two-tier application in two Availability Zones in the us-east-1 Region. The databases are deployed in a private subnet while the web servers are deployed in a public subnet. An internet gateway is attached to the VPC. The application and database run on Amazon EC2 instances. The database servers are unable to access patches on the internet. A solutions architect needs to design a solution that maintains database security with the least operational overhead.
Which solution meets these requirements?
  • A. Deploy a NAT gateway inside the public subnet for each Availability Zone and associate it with an Elastic IP address. Update the routing table of the private subnet to use it as the default route.
  • B. Deploy a NAT gateway inside the private subnet for each Availability Zone and associate it with an Elastic IP address. Update the routing table of the private subnet to use it as the default route.
  • C. Deploy two NAT instances inside the public subnet for each Availability Zone and associate them with Elastic IP addresses. Update the routing table of the private subnet to use it as the default route.
  • D. Deploy two NAT instances inside the private subnet for each Availability Zone and associate them with Elastic IP addresses. Update the routing table of the private subnet to use it as the default route.

A solutions architect needs to design a low-latency solution for a static single-page application accessed by users utilizing a custom domain name. The solution must be serverless, encrypted in transit, and cost-effective.
Which combination of AWS services and features should the solutions architect use? (Choose two.)
  • A. Amazon S3
  • B. Amazon EC2
  • C. AWS Fargate
  • D. Amazon CloudFront
  • E. Elastic Load Balancer

A company is migrating to the AWS Cloud. A file server is the first workload to migrate. Users must be able to access the file share using the Server Message
Block (SMB) protocol. Which AWS managed service meets these requirements?
  • A. Amazon Elastic Block Store (Amazon EBS)
  • B. Amazon EC2
  • C. Amazon FSx
  • D. Amazon S3

A monolithic application was recently migrated to AWS and is now running on a single Amazon EC2 instance. Due to application limitations, it is not possible to use automatic scaling to scale out the application. The chief technology officer (CTO) wants an automated solution to restore the EC2 instance in the unlikely event the underlying hardware fails.
What would allow for automatic recovery of the EC2 instance as quickly as possible?
  • A. Configure an Amazon CloudWatch alarm that triggers the recovery of the EC2 instance if it becomes impaired.
  • B. Configure an Amazon CloudWatch alarm to trigger an SNS message that alerts the CTO when the EC2 instance is impaired.
  • C. Configure AWS CloudTrail to monitor the health of the EC2 instance, and if it becomes impaired, trigger instance recovery.
  • D. Configure an Amazon EventBridge event to trigger an AWS Lambda function once an hour that checks the health of the EC2 instance and triggers instance recovery if the EC2 instance is unhealthy.

A solutions architect is working on optimizing a legacy document management application running on Microsoft Windows Server in an on-premises data center.
The application stores a large number of files on a network file share. The chief information officer wants to reduce the on-premises data center footprint and minimize storage costs by moving on-premises storage to AWS.
What should the solutions architect do to meet these requirements?
  • A. Set up an AWS Storage Gateway file gateway.
  • B. Set up Amazon Elastic File System (Amazon EFS)
  • C. Set up AWS Storage Gateway as a volume gateway
  • D. Set up an Amazon Elastic Block Store (Amazon EBS) volume.

A solutions architect is designing a hybrid application using the AWS cloud. The network between the on-premises data center and AWS will use an AWS Direct
Connect (DX) connection. The application connectivity between AWS and the on-premises data center must be highly resilient.
Which DX configuration should be implemented to meet these requirements?
  • A. Configure a DX connection with a VPN on top of it.
  • B. Configure DX connections at multiple DX locations.
  • C. Configure a DX connection using the most reliable DX partner.
  • D. Configure multiple virtual interfaces on top of a DX connection.

A company runs an application on Amazon EC2 instances. The application is deployed in private subnets in three Availability Zones of the us-east-1 Region. The instances must be able to connect to the internet to download files. The company wants a design that is highly available across the Region.
Which solution should be implemented to ensure that there are no disruptions to internet connectivity?
  • A. Deploy a NAT instance in a private subnet of each Availability Zone.
  • B. Deploy a NAT gateway in a public subnet of each Availability Zone.
  • C. Deploy a transit gateway in a private subnet of each Availability Zone.
  • D. Deploy an internet gateway in a public subnet of each Availability Zone.

Application developers have noticed that a production application is very slow when business reporting users run large production reports against the Amazon
RDS instance backing the application. The CPU and memory utilization metrics for the RDS instance do not exceed 60% while the reporting queries are running.
The business reporting users must be able to generate reports without affecting the application's performance.
Which action will accomplish this?
  • A. Increase the size of the RDS instance.
  • B. Create a read replica and connect the application to it.
  • C. Enable multiple Availability Zones on the RDS instance.
  • D. Create a read replica and connect the business reports to it.
