The company recently discovered that a new custom reporting application has Increased the number of Queries on the database.
This is slowing down performance.
How should a solutions architect resolve this issue with the LEAST amount of application changes?

• A.Set up a road replica ana Multi-AZ on Amazon RDS.
• B.Use caching on Amazon RDS to improve the overall performance
• C.Set up a standby replica and Multi-AZ on Amazon RDS
• D.Add a secondary DB instance using Multi-AZ

A solutions architect is designing a new service behind Amazon API Gateway The request patterns for the service will be unpredictable and can change suddenly from 0 requests to over 500 per second The total size of the data that needs to be persisted in a backend database is currently less than 1 GB with unpredictable future growth Data can be queried using simple key-value requests Which combination of AWS services would meet these requirements? (Select TWO )

• A.AWS Fargate
• B.AWS Lambda
• C.Amazon DynamoDB
• D.Amazon EC2 Auto Scaling
• E.MySQL-compatible Amazon Aurora

Which action should the team take to ensure high availability?

• A.Create a DynamoDB stream for the DynamoDB table.
• B.Enable Multi-AZ on the RDS for PostgreSQL database.
• C.Create a Lambda function for each Availability Zone the application is deployed in.
• D.Enable Cross-Region Replication in the S3 bucket.

A company has recently updated its internal security standards The company must now ensure all Amazon S3 buckets and Amazon Elastic Block Store (Amazon EBS) volumes are encrypted with keys created and periodically rotated by internal security specialists The company is looking for a native, software-based AWS service to accomplish this goal What should a solutions architect recommend as a solution?

• A.Use AWS Systems Manager Parameter Store with customer master keys (CMKs) to store master key material and apply a routine to re-create a new key periodically and replace it in the Parameter Store
• B.Use an AWS CloudHSM cluster with customer master keys (CMKs) to store master key material and apply a routine to re-create a new key periodically and replace it in the CloudHSM cluster nodes
• C.Use AWS Key Management Service (AWS KMS) with customer master keys (CMKs) to store master key material and apply a routine to re-create a new key periodically and replace it in AWS KMS.
• D.Use AWS Secrets Manager with customer master keys (CMKs) to store master key material and apply a routine to create a new CMK periodically and replace it m AWS Secrets Manager

A company has two VPCs named Management and Production The Management VPC uses VPNs through a customer gateway to connect to a single device in the data center. The Production VPC uses a virtual private gateway with two attached AWS Direct Connect connections The Management and Production VPCs both use a single VPC peering connection to allow communication between the applications.
What should a solutions architect do to mitigate any single point of failure in this architecture?

• A.Add a set of VPNs between the Management and Production VPCs
• B.Add a second virtual private gateway and attach it to the Management VPC.
• C.Add a second set of VPNs to the Management VPC from a second customer gateway device
• D.Add a second VPC peering connection between the Management VPC and the Production VPC.
