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?Read More →

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?Read More →

A company operates an on-premises software-as-a-service (SaaS) solution that ingests several files daily.The company provides multiple public SFTP endpoints to its customers to facilitate the file transfers.The customers add the SFTP endpoint IP addresses to their firewall allow list for outbound traffic.Changes to theSFTP endpoint IP addresses are not permitted.The company wants to migrate the SaaS solution to AWS and decrease the operational overhead of the file transfer service.Which solution meets these requirements?Read More →

A medical company is building a data lake on Amazon S3.The data must be encrypted in transit and at rest.The data must remain protected even if S3 bucket is inadvertently made public.Which combination of steps will meet these requirements? (Choose three.)Read More →

A company is using a lift-and-shift strategy to migrate applications from several on-premises Windows servers to AWS.The Windows servers will be hosted onAmazon EC2 instances in the us-east-1 Region.The company’s security policy allows the installation of migration tools on servers.The migration data must be encrypted in transit and encrypted at rest.The applications are business critical.The company needs to minimize the cutover window and minimize the downtime that results from the migration.The company wants to use Amazon CloudWatch and AWS CloudTrail for monitoring.Which solution will meet these requirements?Read More →

A company has a web application that uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB.A recent marketing campaign has increased demand.Monitoring software reports that many requests have significantly longer response times than before the marketing campaign.A solutions architect enabled Amazon CloudWatch Logs for API Gateway and noticed that errors are occurring on 20% of the requests.In CloudWatch, theLambda function Throttles metric represents 1% of the requests and the Errors metric represents 10% of the requests.Application logs indicate that, when errors occur, there is a call to DynamoDB.What change should the solutions architect make to improve the current response times as the web application becomes more popular?Read More →

A company wants to move a web application to AWS.The application stores session information locally on each web server, which will make auto scaling difficult.As part of the migration, the application will be rewritten to decouple the session data from the web servers.The company requires low latency, scalability, and availability.Which service will meet the requirements for storing the session information in the MOST cost-effective way?Read More →

A company that provides wireless services needs a solution to store and analyze log files about user activities.Currently, log files are delivered daily to AmazonLinux on an Amazon EC2 instance.A batch script is run once a day to aggregate data used for analysis by a third-party tool.The data pushed to the third-party tool is used to generate a visualization for end users.The batch script is cumbersome to maintain, and it takes several hours to deliver the ever-increasing data volumes to the third-party tool.The company wants to lower costs, and is open to considering a new tool that minimizes development effort and lowers administrative overhead.The company wants to build a more agile solution that can store and perform the analysis in near-real time, with minimal overhead.The solution needs to be cost effective and scalable to meet the company’s end-user base growth.Which solution meets the company’s requirements?Read More →

A company runs a dynamic mission-critical web application that has an SLA of 99.99%.Global application users access the application 24/7.The application is currently hosted on premises and routinely fails to meet its SLA, especially when millions of users access the application concurrently.Remote users complain of latency.How should this application be redesigned to be scalable and allow for automatic failover at the lowest cost?Read More →

A company is using AWS to run an internet-facing production application written in Node.js.The Development team is responsible for pushing new versions of their software directly to production.The application software is updated multiple times a day.The team needs guidance from a Solutions Architect to help them deploy the software to the production fleet quickly and with the least amount of disruption to the service.Which option meets these requirements?Read More →
