A company has an application that is deployed on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are part of an Auto Scaling group. The application has unpredictable workloads and frequently scales out and in. The company's development team wants to analyze application logs to find ways to improve the application's performance. However, the logs are no longer available after instances scale in.
Which solution will give the development team the ability to view the application logs after a scale-in event?
B
A company is deploying a new cluster for big data analytics on AWS. The cluster will run across many Linux Amazon EC2 instances that are spread across multiple Availability Zones.
All of the nodes in the cluster must have read and write access to common underlying file storage. The file storage must be highly available, must be resilient, must be compatible with the Portable Operating System Interface (POSIX), and must accommodate high levels of throughput.
Which storage solution will meet these requirements?
B
A company had a third-party audit of its AWS environment. The auditor identified secrets in developer documentation and found secrets that were hardcoded into AWS CloudFormation templates throughout the environment. The auditor also identified security groups that allowed inbound traffic from the internet and outbound traffic to all destinations on the internet.
A solutions architect must design a solution that will encrypt all secrets and rotate the secrets every 90 days. Additionally, the solutions architect must configure the security groups to prevent resources from being accessible from the internet.
Which solution will meet these requirements?
D
A company is running an application on Amazon EC2 instances in the AWS Cloud. The application is using a MongoDB database with a replica set as its data tier. The MongoDB database is installed on systems in the company's on-premises data center and is accessible through an AWS Direct Connect connection to the data center environment.
A solutions architect must migrate the on-premises MongoDB database to Amazon DocumentDB (with MongoDB compatibility).
Which strategy should the solutions architect choose to perform this migration?
C
A company is deploying a new API to AWS. The API uses Amazon API Gateway with a Regional API endpoint and an AWS Lambda function for hosting. The API retrieves data from an external vendor API, stores data in an Amazon DynamoDB global table, and retrieves data from the DynamoDB global table. The API key for the vendor's API is stored in AWS Secrets Manager and is encrypted with a customer managed key in AWS Key Management Service (AWS KMS). The company has deployed its own API into a single AWS Region.
A solutions architect needs to change the API components of the company's API to ensure that the components can run across multiple Regions in an active-active configuration.
Which combination of changes will meet this requirement with the LEAST operational overhead? (Choose three.)
BDF
A company deploys workloads in multiple AWS accounts. Each account has a VPC with VPC flow logs published in text log format to a centralized Amazon S3 bucket. Each log file is compressed with gzip compression. The company must retain the log files indefinitely.
A security engineer occasionally analyzes the logs by using Amazon Athena to query the VPC flow logs. The query performance is degrading over time as the number of ingested logs is growing. A solutions architect must improve the performance of the log analysis and reduce the storage space that the VPC flow logs use.
Which solution will meet these requirements with the LARGEST performance improvement?
B
A company's solutions architect is managing a learning platform that supports more than 1 million students. The company's business reporting team is experiencing slow performance while extracting large datasets from the database. The learning application is based on PHP and runs on Amazon EC2 instances that are in an Amazon EC2 Auto Scaling group behind an Application Load Balancer (ALB). Application data is stored in an Amazon S3 bucket and in an Amazon RDS for MySOL database. The ALB is the origin of an Amazon CloudFront distribution.
The solutions architect observes that slow read operations for SELECT queries are affecting the RDS for MySOL DB instance's CPU utilization. The solutions architect must find a scalable solution to improve the slow website performance with near-zero downtime. The solution also must provide automatic failover with no data loss.
Which solution will meet these requirements?
C
A company is using IoT devices on its manufacturing equipment. Data from the devices travels to the AWS Cloud through a connection to AWS IoT Core. An Amazon Kinesis data stream sends the data from AWS IoT Core to the company's processing application. The processing application stores data in Amazon S3.
A new requirement states that the company also must send the raw data to a third-party system by using an HTTP API.
Which solution will meet these requirements with the LEAST amount of development work?
D
A solutions architect is deploying a web application that consists of a web tier, an application tier, and a database tier. The infrastructure must be highly available across two Availability Zones. The solution must minimize single points of failure and must be resilient.
Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)
