A user owns a MySQL database that is accessed by various clients who expect, at most, 100 ms latency on requests. Once a record is stored in the database, it is rarely changed. Clients only access one record al a time. Database access has been increasing exponentially due to increased client demand. The resultant load will soon exceed the capacity of the most expensive hardware available for purchase. The user wants to migrate to AWS, and is willing to change database systems.
Which service would alleviate the database load issue and offer virtually unlimited scalability for the future?
A. Amazon RDS
B. Amazon DynamoDB
C. Amazon Redshift
D. AWS Data Pipeline
A company has an AWS Direct Connect connection from its corporate data center to its VPC in the useast-1 Region The company recently acquired a corporation that has several VPCs and a Direct Connect connection between its on-premises data center and the eu-west-2 Region The CIDR blocks for the VPCs of the company and the corporation do not overlap The company requires connectivity between two Regions and the data centers The company needs a solution that is scalable while reducing operational overhead What should a solutions architect do to meet these requirements?
A. Set up inter-Region VPC peering between the VPC m us-east-1 and the VPCs in eu-west-2
B. Create private virtual interfaces from the Direct Connect connection in us-east-1 to the VPCs in eu-west-2
C. Establish VPN appliances in a fully meshed VPN network hosted by Amazon EC2 Use AWS VPN CloudHub to send and receive data between the data centers and each VPC D. Connect the existing Direct Connect connection to a Direct Connect gateway Route traffic from the virtual private gateways of the VPCs in each Region to the Direct Connect gateway

A company receives data from different sources and implements multiple applications to consume this data There are many short-running jobs that run only on the weekend. The data arrives in batches rather than throughout the entire
weekend. The company needs an environment on AWS to ingest and process this data while maintaining the order of the transactions.
Which combination of AWS services meets these requirements in the MOST cost-effective manner?
A. Amazon Kinesis Data Streams with AWS Lambda
B. Amazon Kinesis Data Streams with Amazon EC2 Auto Scaling
C. Amazon Simple Queue Service (Amazon SQS) with AWS Lambda
D. Amazon Simple Queue Service (Amazon SQS) with Amazon EC2 Auto Scaling
A global company plans to track and store information about local allergens in an Amazon DynamoOB table and query this data from its website The company anticipates that website traffic will fluctuate The company estimates that the
combined read and write capacity units will range from 10 10.000 per second, depending on the severity of the conditions for the given day. A solutions architect must design a solution that avoids throttling issues and manages capacity
efficiently.
What should the solutions architect do to meet these requirements MOST cost-effectively'?
A. use provisioned capacity mode. Set the table's read capacity units to 10,000.
B. Use provisioned capacity mode and a scaling policy in DynamoDB auto scaling
C. Use on demand capacity made for a couple of months Then switch to provisioned capacity mode
D. Use on-demand capacity mode only. Configure DynamoDB Accelerator (DAX) to be in front of the tab

E. Use Amazon Inspector to identify underutilized EC2 instances.
A solutions architect is using an AWS Cloud Formation template to deploy a three-tier web application The web application consists of a web tier and an application tier that stores and retrieves user data in Amazon DynamoDB tables The web and application tiers are hosted on Amazon EC2 instances, and the database tier is not publicly accessible The application EC2 instances need to access the DynamoDB tables without exposing API credentials in the template What should the solutions architect do to meet these requirements?
A. Create an 1AM role to read the DynamoOB tables Associate the role with the application instances by reference an instance profile
B. Create an IAM role that has the required permissions to read and write from the DynamoOB tables Add the role to the EC2 instance profile and associate the instance profile with the apphcanon instances
C. Use the parameter section in the AWS CkHidFormaton template to have the user input access and secret keys from an already-created IAM user mat has the required permissions to read and write from the DynamoOB tables
D. Create an IAM user m the AWS CioudFormation template that has the required permissions to read and write from the DynamoOB tables Use the GetAti function to retrieve the access and secret keys and pass them to the application instances through the user data
A company has an application that scans millions of connected devices for security threats and pushes the scan logs to an Amazon S3 bucket. A total of 70 GB of data is generated each week, and the company needs to store 3 years of data
for historical reporting. The company must process, aggregate, and enrich the data from Amazon S3 by performing complex analytical queries and joins in the least amount of time. The aggregated dataset is visualized on an Amazon
QuickSight dashboard.
What should a solutions architect recommend to meet these requirements?
A. Create and run an ETL job in AWS Glue to process the data from Amazon S3 and load it into Amazon Redshift. Perform the aggregation queries on Amazon Redshift.
B. Use AWS Lambda functions based on S3 PutObject event triggers to copy the incremental changes to Amazon DynamoDB. Perform the aggregation queries on DynamoDB.
C. Use AWS Lambda functions based on S3 PutObject event triggers to copy the incremental changes to Amazon Aurora MySQL Perform the aggregation queries on Aurora MySQL
D. Use AWS Glue to catalog the data in Amazon S3. Perform the aggregation queries on the cataloged tables by using Amazon Athena. Query the data directly from Amazon S3.
