A company runs an loT platform on AWS loT sensors in various locations send data to the company's Node js API servers on Amazon EC2 instances running behind an Application Load Balancer The data is stored in an Amazon RDS MySQL DB instance that uses a 4 TB General Purpose SSD volume
The number of sensors the company has deployed in the field has increased over time and is expected to grow significantly The API servers are consistently overloaded and RDS metrics show high write latency
Which of the following steps together will resolve the issues permanently and enable growth as new sensors are provisioned, while keeping this platform cost-efficient? {Select TWO.)

1. A. Resize the MySQL General Purpose SSD storage to 6 TB to improve the volume's IOPS
2. B. Re-architect the database tier to use Amazon Aurora instead of an RDS MySQL DB instance and add read replicas
3. C. Leverage Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data
4. D. Use AWS X-Ray to analyze and debug application issues and add more API servers to match the load
5. E. Re-architect the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance

A company's security compliance requirements state that all Amazon EC2 images must be scanned for vulnerabilities and must pass a CVE assessment A solutions architect is developing a mechanism to create security-approved AMIs that can be used by developers Any new AMIs should go through an automated assessment process and be marked as approved before developers can use them The approved images must be scanned every 30 days to ensure compliance
Which combination of steps should the solutions architect take to meet these requirements while following best practices'? (Select TWO )

1. A. Use the AWS Systems Manager EC2 agent to run the CVE assessment on the EC2 instances launched from the AMIs that need to be scanned
2. B. Use AWS Lambda to write automatic approval rules Store the approved AMI list in AWS Systems Manager Parameter Store Use Amazon EventBridge to trigger an AWS Systems Manager Automation document on all EC2 instances every 30 days.
3. C. Use Amazon Inspector to run the CVE assessment on the EC2 instances launched from the AMIs that need to be scanned
4. D. Use AWS Lambda to write automatic approval rules Store the approved AMI list in AWS Systems Manager Parameter Store Use a managed AWS Config rule for continuous scanning on all EC2 instances, and use AWS Systems Manager Automation documents for remediation
5. E. Use AWS CloudTrail to run the CVE assessment on the EC2 instances launched from the AMIs that need to be scanned

A company is collecting a large amount of data from a fleet of loT devices. Data is stored as Optimized Row Columnar (ORC) files in the Hadoop Distributed File System (HDFS) on a persistent Amazon EMR cluster. The company's data analytics team queries the data by using SQL in Apache Presto deployed on the same EMR cluster Queries scan large amounts of data always run for less than 15 minutes, and run only between 5 PM and 10 PM.
The company is concerned about the high cost associated with the current solution A solutions architect must propose the most cost-effective solution that will allow SQL data queries.
Which solution will meet these requirements?

1. A. Store data m Amazon S3 Use Amazon Redshift Spectrum to query data.
2. B. Store data m Amazon S3 Use the AWS Glue Data Catalog and Amazon Athena to query data.
3. C. Store data in EMR File System (EMRFS). Use Presto n Amazon EMR to query data.
4. D. Store data in Amazon Redshift Use Amazon Redshift to query data

A solutions architect is importing a VM from an on-premises environment by using the Amazon EC2 VM Import feature of AWS Import/Export The solutions architect has created an AMI and has provisioned an Amazon EC2 instance that is based on that AMI The EC2 instance runs inside a public subnet in a VPC and has a public IP address assigned
The EC2 instance does not appear as a managed instance in the AWS Systems Manager console
Which combination of steps should the solutions architect take to troubleshoot this issue"? (Select TWO )

1. A. Verify that Systems Manager Agent is installed on the instance and is running
2. B. Verify that the instance is assigned an appropriate IAM role for Systems Manager
3. C. Verify the existence of a VPC endpoint on the VPC
4. D. Verify that the AWS Application Discovery Agent is configured
5. E. Verify the correct configuration of service-linked roles for Systems Manager

A company is finalizing the architecture for its backup solution for applications running on AWS. All of the applications run on AWS and use at least two Availability Zones in each tier.
Company policy requires IT to durably store nightly backups of all its data in at least two locations: production and disaster recovery. The locations must be m different geographic regions. The company also needs the backup to be available to restore immediately at the production data center, and within 24 hours at the disaster recovery location backup processes must be fully automated.
What is the MOST cost-effective backup solution that will meet all requirements?

1. A. Back up all the data to a large Amazon EBS volume attached to the backup media server m the production regio
2. B. Run automated scripts to snapshot these volumes nightl
3. C. and copy these snapshots to the disaster recovery region.
4. D. Back up all the data to Amazon S3 in the disaster recovery region Use a Lifecycle policy to move this data to Amazon Glacier in the production region immediately Only the data is replicated: remove the data from the S3 bucket in the disaster recovery region.
5. E. Back up all the data to Amazon Glacier in the production regio
6. F. Set up cross-region replication of this data to Amazon Glacier in the disaster recovery regio
7. G. Set up a lifecycle policy to delete any data o der than 60 days.
8. H. Back up all the data to Amazon S3 in the production regio
9. I. Set up cross-region replication of this S3 bucket to another region and set up a lifecycle policy in the second region to immediately move this data to Amazon Glacier
