A company has created an isolated backup of its environment in another Region. The application is running in warm standby mode and is fronted by an Application Load Balancer (ALB). The current failover process is manual and requires updating a DNS alias record to point to the secondary ALB in another Region.
What should a solutions architect do to automate the failover process?
A. Enable an ALB health check.
B. Enable an Amazon Route 53 health check.
C. Create a CNAME record on Amazon Route 53 pointing to the ALB endpoint.
D. Create conditional forwarding rules on Amazon Route 53 pointing to an internal BIND DNS server.
A company that recently started using AWS establishes a Site-to-Site VPN between its on-premises data center and AWS. The company's security mandate states that traffic originating from on premises should stay within the company's
private IP space when communicating with an Amazon Elastic Container Service (Amazon ECS) cluster that is hosting a sample web application.
Which solution meets this requirement?
A. Configure a gateway endpoint for Amazon ECS. Modify the route table to include an entry pointing to the ECS cluster.
B. Create a Network Load Balancer and AWS PrivateLink endpoint for Amazon ECS in the same VPC that is hosting the ECS cluster.
C. Create a Network Load Balancer in one VPC and an AWS PrivateLink endpoint for Amazon ECS in another VPC. Connect the two VPCs by using VPC peering.
D. Configure an Amazon Route 53 record with Amazon ECS as the target. Apply a server certificate to Route 53 from AWS Certificate Manager (ACM) for SSL offloading.
A Solutions architect is designing the cloud architecture for a company that needs to host hundreds of machine learning models for its users. During startup, the models need to load up to 10 GB of data from Amazon S3 into memory, but they do not need disk access. Most of the models are used sporadically, but the users expect all of them to be highly available and accessible with low latency.
Which solution meets the requirements and is MOST cost-effective?
A. Deploy models as AWS Lambda functions behind an Amazon API Gateway for each model.
B. Deploy models as Amazon Elastic Container Service (Amazon ECS) services behind an Application Load Balancer for each model.
C. Deploy models as AWS Lambda functions behind a single Amazon API Gateway with path-based routing where one path corresponds to each model.
D. Deploy models as Amazon Elastic Container Service (Amazon ECS) services behind a single Application Load Balancer with path-based routing where one path corresponds to each model.
A company wants to move its on-premises network, attached storage (NAS) to AWS. The company wants to make the data available to any Linux instances within its VPC and ensure changes are automatically synchronized across all instances accessing the data store. The majority of the data is accessed very rarely, and some files are accessed by multiple users at the same time. Which solution meets these requirements and is MOST cost-effective?
A. Create an Amazon Elastic Block Store (Amazon EBS) snapshot containing the data. Share it with users within the VPC.
B. Create an Amazon S3 bucket that has a lifecycle policy set to transition the data to S3 Standard- Infrequent Access (S3 Standard-IA) after the appropriate number of days.
C. Create an Amazon Elastic File System (Amazon EFS) file system within the VPC. Set the throughput mode to Provisioned and to the required amount of IOPS to support concurrent usage.
D. Create an Amazon Elastic File System (Amazon EFS) file system within the VPC. Set the lifecycle policy to transition the data to S Infrequent Access (EFS IA) after the appropriate number of days.
A company is. moving its on-premises applications to Amazon EC2 instances. However as a result of fluctuating compute requirements, the EC2 instances must always be ready to use between 8 AM and 5 PM in specific Availability Zones. Which EC2 instances should the company choose to run the applications?
A. Scheduled Reserved I Instances
B. On-Demand Instances
C. Spot Instances as part of a Spot Fleet
D. EC2 instances in an Auto Scaling group
A company hosts more than 300 global websites and applications. The company requires a platform to analyze more than 30 TB of clickstream data each day. What should a solutions architect do to transmit and process the clickstream data?
A. Design an AWS Data Pipeline to archive the data to an Amazon S3 bucket and run an Amazon EMR cluster with the data to generate analytics.
B. Create an Auto Scaling group of Amazon EC2 instances to process the data and send it to an Amazon S3 data lake for Amazon Redshift to use for analysis.
C. Cache the data to Amazon CloudFront. Store the data in an Amazon S3 bucket. When an object is added to the S3 bucket, run an AWS Lambda function to process the data for analysis.
D. Collect the data from Amazon Kinesis Data Streams. Use Amazon Kinesis Data firehose to transmit the data to an Amazon S3 data lake. Load the data in Amazon Redshift for analysis.
A company is preparing to deploy a new serverless workload. A solutions architect needs to configure permissions for invoking an AWS Lambda function. The function will be triggered by an Amazon EventBridge (Amazon CloudWatch
Events) rule. Permissions should be configured using the principle of least privilege.
Which solution will meet these requirements?
A. Add an execution role to the function with lambda;lnvokeFunction as the action and * as the principal.
B. Add an execution rote to the function with lambda;lnvokeFunction as the action and Service:eventsamazonaws.com as the principal.
C. Add a resource-based policy to the function with lambda;' as the action and Service:events.amazonaws.com as the principal.
D. Add a resource-based policy to the function with lambda;InvokeFunction as the action and Service: events.amazonaws.com as the principal.
A bicycle sharing company is developing a multi-tier architecture to track the location of its bicycles during peak operating hours. The company wants to use these data points in its existing analytics platform. A solutions architect must determine the most viable multi-tier option to support this architecture. The data points must be accessible from the REST API. Which action meets these requirements for storing and retrieving location data?
A. Use Amazon Athena with Amazon S3.
B. Use Amazon API Gateway with AWS Lambda.
C. Use Amazon QuickSight with Amazon Redshift.
D. Use Amazon API Gateway with Amazon Kinesis Data Analytics.
A company recently started using Amazon Aurora as the data store for its global ecommerce application. When large reports are run, developers report that the ecommerce application is performing poorly. After reviewing metrics in Amazon
CloudWatch, a solutions architect finds that the ReadlOPS and CPU Utilization metrics are spiking when monthly reports run.
What is the MOST cost-effective solution?
A. Migrate the monthly reporting to Amazon Redshift.
B. Migrate the monthly reporting to an Aurora Replica.
C. Migrate the Aurora database to a larger instance class.
D. Increase the Provisioned IOPS on the Aurora instance.
A company is developing an ecommerce application that will consist of a load-balanced front end. a container-based application and a relational database A solutions architect needs to create a highly available solution that operates with as little manual intervention as possible Which solutions meet these requirements? (Select TWO.)
A. Create an Amazon RDS DB instance in Multi-AZ mode
B. Create an Amazon RDS DB instance and one or more replicas in another Availability Zone
C. Create an Amazon EC2 instance-based Docker cluster to handle the dynamic application load
D. Create an Amazon Elastic Container Service (Amazon ECS) cluster with a Fargate launch type to handle the dynamic application load
E. Create an Amazon Elastic Container Service (Amazon ECS) cluster with an Amazon EC2 launch type to handle the dynamic application load
