A large company has a business-critical application that runs in a single AWS Region.The application consists of multiple Amazon EC2 instances and an AmazonRDS Multi-AZ DB instance.The EC2 instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones.A solutions architect is implementing a disaster recovery (DR) plan for the application.The solutions architect has created a pilot light application deployment in a new Region, which is referred to as the DR Region.The DR environment has an Auto Scaling group with a single EC2 instance and a read replica of the RDS DB instance.The solutions architect must automate a failover from the primary application environment to the pilot light environment in the DR Region.Which solution meets these requirements with the MOST operational efficiency?Read More →

A company wants to migrate a 30 TB Oracle data warehouse from on premises to Amazon Redshift.The company used the AWS Schema Conversion Tool (AWSSCT) to convert the schema of the existing data warehouse to an Amazon Redshift schema.The company also used a migration assessment report to identify manual tasks to complete.The company needs to migrate the data to the new Amazon Redshift cluster during an upcoming data freeze period of 2 weeks.The only network connection between the on-premises data warehouse and AWS is a 50 Mbps internet connection.Which migration strategy meets these requirements?Read More →

A large company runs workloads in VPCs that are deployed across hundreds of AWS accounts.Each VPC consists of public subnets and private subnets that span across multiple Availability Zones.NAT gateways are deployed in the public subnets and allow outbound connectivity to the internet from the private subnets.A solutions architect is working on a hub-and-spoke design.All private subnets in the spoke VPCs must route traffic to the internet through an egress VPC.The solutions architect already has deployed a NAT gateway in an egress VPC in a central AWS account.Which set of additional steps should the solutions architect take to meet these requirements?Read More →

A company is configuring connectivity to a multi-account AWS environment to support application workloads that serve users in a single geographic region.The workloads depend on a highly available, on-premises legacy system deployed across two locations.It is critical for the AWS workloads to maintain connectivity to the legacy system, and a minimum of 5 Gbps of bandwidth is required.All application workloads within AWS must have connectivity with one another.Which solution will meet these requirements?Read More →

A company wants to provide desktop as a service (DaaS) to a number of employees using Amazon WorkSpaces.WorkSpaces will need to access files and services hosted on premises with authorization based on the company’s Active Directory.Network connectivity will be provided through an existing AWS DirectConnect connection.The solution has the following requirements:✑ Credentials from Active Directory should be used to access on-premises files and services.✑ Credentials from Active Directory should not be stored outside the company.✑ End users should have single sign-on (SSO) to on-premises files and services once connected to WorkSpaces.Which strategy should the solutions architect use for end user authentication?Read More →

A company is currently in the design phase of an application that will need an RPO of less than 5 minutes and an RTO of less than 10 minutes.The solutions architecture team is forecasting that the database will store approximately 10 TB of data.As part of the design, they are looking for a database solution that will provide the company with the ability to fail over to a secondary Region.Which solution will meet these business requirements at the LOWEST cost?Read More →

An ecommerce website running on AWS uses an Amazon RDS for MySQL DB instance with General Purpose SSD storage.The developers chose an appropriate instance type based on demand, and configured 100 GB of storage with a sufficient amount of free space.The website was running smoothly for a few weeks until a marketing campaign launched.On the second day of the campaign, users reported long wait times and time outs.Amazon CloudWatch metrics indicated that both reads and writes to the DB instance were experiencing long response times.The CloudWatch metrics show 40% to 50% CPU and memory utilization, and sufficient free storage space is still available.The application server logs show no evidence of database connectivity issues.What could be the root cause of the issue with the marketing campaign?Read More →

A company asks a solution architect to optimize the cost of a solution.The solution handles requests from multiple customers.The solution includes a multi-tier architecture that uses Amazon API Gateway, AWS Lambda, AWS Fargate, Amazon Simple Queue Service (Amazon SQS), and Amazon EC2.In the current setup, requests go through API Gateway to Lambda and either start a container in Fargate or push a message to an SQS queue.An EC2 Fleet provides EC2 instances that serve as workers for the SQS queue.The EC2 Fleet scales based on the number of items in the SQS queue.Which combination of steps should the solutions architect recommend to reduce cost the MOST? (Choose three.)Read More →

A company is migrating its three-tier web application from on-premises to the AWS Cloud.The company has the following requirements for the migration process:✑ Ingest machine images from the on-premises environment.✑ Synchronize changes from the on-premises environment to the AWS environment until the production cutover.✑ Minimize downtime when executing the production cutover.✑ Migrate the virtual machines’ root volumes and data volumes.Which solution will satisfy these requirements with minimal operational overhead?Read More →

A company is currently running a production workload on AWS that is very I/O intensive.Its workload consists of a single tier with 10 c4.8xlarge instances, each with 2 TB gp2 volumes.The number of processing jobs has recently increased, and latency has increased as well.The team realizes that they are constrained on the IOPS.For the application to perform efficiently, they need to increase the IOPS by 3,000 for each of the instances.Which of the following designs will meet the performance goal MOST cost effectively?Read More →
