A company has a website deployed on AWS. The database backend is hosted on Amazon RDS for MySQL with a primary instance and five read replicas to support scaling needs. The read replicas should lag no more than 1 second behind the primary instance to support the user experience As traffic on the website continues to increase, the replicas are falling further behind during periods of peak load, resulting in complaints from users when searches yield inconsistent results A solutions architect needs to reduce the replication lag as much as possible, with minimal changes to the application code or operational requirements Which solution meets these requirements?
A. Migrate the database to Amazon Aurora MySQL Replace the MySQL read replicas with Aurora Replicas and enable Aurora Auto Scaling
B. Deploy an Amazon ElastiCache for Redis cluster in front of the database Modify the website to check the cache before querying the database read endpoints
C. Migrate the database from Amazon RDS to MySQL running on Amazon EC2 compute instances.Choose very large compute optimized instances for all replica nodes.
D. Migrate the database to Amazon DynamoDB Initially provision a large number of read capacity units (RCUs) to support the required throughput with on-demand capacity scaling enabled
Which solution will improve the performance of the application when it is moved to AWS?
A. Import the data into an Amazon DynamoDB table with provisioned capacity. Refactor the application to use DynamoDB for reports.
B. Create the database on a compute optimized Amazon EC2 instance Ensure compute resources exceed the on-premises database
C. Create an Amazon Aurora MySQL Multi-AZ DB cluster with multiple read replicas. Configure the application to use the reader endpoint tor reports.
D. Create an Amazon Aurora MySQL Multi-AZ DB cluster Configure The application to use the backup instance of the cluster as an endpoint for the reports.
A company has no existing file share services. A new project requires access to file storage that is mountable as a drive for on-premises desktops. The file server must authenticate users to an Active Directory domain before they are able to access the storage.
Which service will allow Active Directory users to mount storage as a drive on their desktops?
A. Amazon S3 Glacier
B. AWS DataSync
C. AWS Snowball Edge
D. AWS Storage Gateway
A company needs to comply with a regulatory requirement that states all emails must Pe stored and archived externally for 7 years. An administrator has created compressed email files on premises and wants a managed service to transfer the files to AWS storage. Which managed service should a solutions architect recommend?
A. Amazon Elastic File System (Amazon EPS)
B. Amazon S3 Glacier
C. AWS Backup
D. AWS Storage Gateway
A company has 700 TB of backup data stored in network attached storage (NAS) in its data center This backup data need to be accessible for infrequent regulatory requests and must be retained 7 years. The company has decided to migrate this backup data from its data center to AWS. The migration must be complete within 1 month The company has 500 Mbps of dedicated bandwidth on its public internet connection available for data transfer. What should a solutions architect do to migrate and store the data at the LOWEST cost?
A. Order AWS Snowball devices to transfer the data Use a lifecycle policy to transition the files to Amazon S3 Glacier Deep Archive
B. Deploy a VPN connection between the data center and Amazon VPC Us?the AWS CLI to copy the data from on premises to Amazon S3 Glacier.
C. Provision a 500 Mbps AWS Direct Connect connection and transfer the data to Amazon S3. Use a lifecycle policy to transition the files to Amazon S3 Glacier Deep Archive.
D. Use AWS DataSync to transfer the data and deploy a DataSync agent on premises Use the DataSync task to copy files from the on-premises NAS storage lo Amazon S3 Glacier
A company has a mobile game that reads most of its metadata from an Amazon RDS DB instance As the game increased in popularity developers noticed slowdowns related to the game's metadata load times Performance metrics indicate that simply scaling the database will not help A solutions architect must explore all options that include capabilities for snapshots replication and sub- millisecond response times What should the solutions architect recommend to solve these issues?
A. Migrate the database to Amazon Aurora with Aurora Replicas
B. Migrate the database to Amazon DyramoDB with global tables
C. Add an Amazon ElastiCache for Redis layer in front of the database.
D. Add an Amazon ElastiCache for Memcached layer in front of the database
A company has an application running on Amazon EC2 instances in a private subnet. The application needs to store and retrieve data in Amazon S3. To reduce costs, the company wants to configure its AWS resources in a cost-effective manner.
How should the company accomplish this?
A. Deploy a NAT gateway to access the S3 buckets
B. Deploy AWS Storage Gateway to access the S3 buckets
C. Deploy an S3 gateway endpoint to access the S3 buckets
D. Deploy an S3 interface endpoint to access the S3 buckets.
A company has an application workflow that uses an AWS Lambda function to download and decrypt files from Amazon S3 These files are encrypted using AWS Key Management Service Customer Master Keys (AWS KMS CMKs) A solutions architect needs to design a solution that will ensure the required permissions are set correctly.
Which combination of actions accomplish this? (Select TWO.)
A. Attach the kms.decrypt permission to the Lambda function's resource policy.
B. Grant the decrypt permission for the Lambda IAM role in the KMS key's policy
C. Grant the decrypt permission for the Lambda resource policy in the KMS key's policy.
D. Create a new IAM policy with the kms:decrypt permission and attach the policy to the Lambda function
E. Create a new IAM role with the kms decrypt permission and attach the execution role to the Lambda function.
A company has three VPCs named Development, Testing and Production in the us-east-1 Region. The three VPCs need to be connected to an on-premises data center and are designed to be separate to maintain security and prevent any resource sharing A solutions architect needs to find a scalable and secure solution.
What should the solutions architect recommend?
A. Create an AWS Direct Connect connection and a VPN connection for each VPC to connect back to the data center.
B. Create VPC peers from all the VPCs to the Production VPC Use an AWS Direct Connect connection from the Production VPC back to the data center
C. Connect VPN connections from all the VPCs to a VPN in the Production VPC. Use a VPN connection from the Production VPC back to the data center
D. Create a new VPC called Network Within the Network VPC create an AWS Transit Gateway with an AWS Direct Connect connection back to the data center Attach all the other VPCs to the Network VPC.
A company provides an API to its users that automates inquiries for tax computations based on item prices. The company experiences a larger number of inquiries during the holiday season only that cause slower response times. A solutions architect needs to design a solution that is scalable and elastic What should the solutions architect do to accomplish this?
A. Provide an API hosted on an Amazon EC2 instance. The EC2 instance performs the required computations when the API request is made.
B. Design a REST API using Amazon API Gateway that accepts the item names API Gateway passes item names to AWS Lambda for tax computations
C. Create an Application Load Balancer that has two Amazon EC2 instances behind it. The EC2 instances will compute the tax on the received item names.
D. Design a REST API using Amazon API Gateway that connects with an API hosted on an Amazon EC2 instance API Gateway accepts and passes the item names to the EC2 instance for tax computations
