A healthcare company runs a production workload on AWS that stores highly sensitive personal information.The security team mandates that, for auditing purposes, any AWS API action using AWS account root user credentials must automatically create a high-priority ticket in the company’s ticketing system.The ticketing system has a monthly 3-hour maintenance window when no tickets can be created.To meet security requirements, the company enabled AWS CloudTrail logs and wrote a scheduled AWS Lambda function that uses Amazon Athena to query API actions performed by the root user.The Lambda function submits any actions found to the ticketing system API.During a recent security audit, the security team discovered that several tickets were not created because the ticketing system was unavailable due to planned maintenance.Which combination of steps should a solutions architect take to ensure that the incidents are reported to the ticketing system even during planned maintenance?(Choose two.)Read More →

A company is manually deploying its application to production and wants to move to a more mature deployment pattern.The company has asked a solutions architect to design a solution that leverages its current Chef tools and knowledge.The application must be deployed to a staging environment for testing and verification before being deployed to production.Any new deployment must be rolled back in 5 minutes if errors are discovered after a deployment.Which AWS service and deployment pattern should the solutions architect use to meet these requirements?Read More →

A company wants to migrate virtual Microsoft workloads from an on-premises data center to AWS.The company has successfully tested a few sample workloads on AWS.The company also has created an AWS Site-to-Site VPN connection to a VPC.A solutions architect needs to generate a total cost of ownership (TCO) report for the migration of all the workloads from the data center.Simple Network Management Protocol (SNMP) has been enabled on each VM in the data center.The company cannot add more VMs in the data center and cannot install additional software on the VMs.The discovery data must be automatically imported into AWS Migration Hub.Which solution will meet these requirements?Read More →

A company currently has data hosted in an IBM Db2 database.A web application calls an API that runs stored procedures on the database to retrieve user information data that is read-only.This data is historical in nature and changes on a daily basis.When a user logs in to the application, this data needs to be retrieved within 3 seconds.Each time a user logs in, the stored procedures run.Users log in several times a day to check stock prices.Running this database has become cost-prohibitive due to Db2 CPU licensing.Performance goals are not being met.Timeouts from Db2 are common due to long-running queries.Which approach should a solutions architect take to migrate this solution to AWS?Read More →
