An ecommerce company hosts its analytics application in the AWS Cloud. The application generates about 300 MB of data each month. The data is stored in JSON format. The company is evaluating a disaster recovery solution to back up the data. The data must be accessible in milliseconds if it is needed, and the data must be kept for 30 days.
Which solution meets these requirements MOST cost-effectively?

1. A. Amazon OpenSearch Service (Amazon Elasticsearch Service)
2. B. Amazon S3 Glacier
3. C. Amazon S3 Standard
4. D. Amazon RDS for PostgreSQL

Correct Answer: C

A medical research lab produces data that is related to a new study. The lab wants to make the data available with minimum latency to clinics across the country for their on-premises, file-based applications. The data files are stored in an Amazon S3 bucket that has read-only permissions for each clinic.
What should a solutions architect recommend to meet these requirements?

1. A. Deploy an AWS Storage Gateway file gateway as a virtual machine (VM) on premises at each clinic
2. B. Migrate the files to each clinic’s on-premises applications by using AWS DataSync for processing.
3. C. Deploy an AWS Storage Gateway volume gateway as a virtual machine (VM) on premises at each clinic.
4. D. Attach an Amazon Elastic File System (Amazon EFS) file system to each clinic’s on-premises servers.

Correct Answer: A
AWS Storage Gateway is a service that connects an on-premises software appliance with cloud-based storage to provide seamless and secure integration between an organization's on-premises IT environment and AWS's storage infrastructure. By deploying a file gateway as a virtual machine on each clinic's premises, the medical research lab can provide low-latency access to the data stored in the S3 bucket while maintaining read-only permissions for each clinic. This solution allows the clinics to access the data files directly from their
on-premises file-based applications without the need for data transfer or migration.

A solution architect is designing a company’s disaster recovery (DR) architecture. The company has a MySQL database that runs on an Amazon EC2 instance in a private subnet with scheduled backup. The DR design to include multiple AWS Regions.
Which solution will meet these requiements with the LEAST operational overhead?

1. A. Migrate the MySQL database to multiple EC2 instance
2. B. Configure a standby EC2 instance in the DR Region Turn on replication.
3. C. Migrate the MySQL database to Amazon RD
4. D. Use a Multi-AZ deploymen
5. E. Turn on read replication for the primary DB instance in the different Availability Zones.
6. F. Migrate the MySQL database to an Amazon Aurora global databas
7. G. Host the primary DB cluster in the primary Regio
8. H. Host the secondary DB cluster in the DR Region.
9. I. Store the schedule backup of the MySQL database in an Amazon S3 bucket that is configured for S3 Cross-Region Replication (CRR). Use the data backup to restore the database in the DR Region.

Correct Answer: C

A company is building a solution that will report Amazon EC2 Auto Scaling events across all the applications in an AWS account. The company needs to use a serverless solution to store the EC2 Auto Scaling status data in Amazon S3. The company then will use the data in Amazon S3 to provide near-real-time updates in a dashboard. The solution must not affect the speed of EC2 instance launches.
How should the company move the data to Amazon S3 to meet these requirements?

1. A. Use an Amazon CloudWatch metric stream to send the EC2 Auto Scaling status data to Amazon Kinesis Data Firehos
2. B. Store the data in Amazon S3.
3. C. Launch an Amazon EMR cluster to collect the EC2 Auto Scaling status data and send the data to Amazon Kinesis Data Firehos
4. D. Store the data in Amazon S3.
5. E. Create an Amazon EventBridge rule to invoke an AWS Lambda function on a schedul
6. F. Configure the Lambda function to send the EC2 Auto Scaling status data directly to Amazon S3.
7. G. Use a bootstrap script during the launch of an EC2 instance to install Amazon Kinesis Agen
8. H. Configure Kinesis Agent to collect the EC2 Auto Scaling status data and send the data to Amazon Kinesis Data Firehos
9. I. Store the data in Amazon S3.

Correct Answer: A
You can use metric streams to continually stream CloudWatch metrics to a destination of your choice, with near-real-time delivery and low latency. One of the use cases is Data Lake: create a metric stream and direct it to an Amazon Kinesis Data Firehose delivery stream that delivers your CloudWatch metrics to a data lake such as Amazon S3.
