Question #537 / 1019

A company operates a three-tier e-commerce platform on AWS spanning three Availability Zones. The architecture includes an Application Load Balancer, Amazon EC2 instances for web servers that manage user session states, and a MySQL database hosted on an EC2 instance. The company anticipates unpredictable traffic surges and wants to ensure the platform can scale efficiently while maintaining high availability across all three AZs. Which solution meets these requirements?

A

Migrate the MySQL database to Amazon RDS for MySQL with a Multi-AZ DB cluster deployment. Use Amazon ElastiCache for Redis with high availability to store session data and to cache reads. Migrate the web servers to an Auto Scaling group spanning three Availability Zones.

B

Migrate the MySQL database to Amazon RDS for MySQL with a Multi-AZ DB cluster deployment. Use Amazon ElastiCache for Memcached with high availability to store session data and to cache reads. Migrate the web servers to an Auto Scaling group spanning three Availability Zones.

C

Migrate the MySQL database to Amazon DynamoDB. Use DynamoDB Accelerator (DAX) to cache reads. Store the session data in DynamoDB. Migrate the web servers to an Auto Scaling group spanning three Availability Zones.

D

Migrate the MySQL database to Amazon RDS for MySQL in a single Availability Zone. Use Amazon ElastiCache for Redis with high availability to store session data and to cache reads. Migrate the web servers to an Auto Scaling group spanning three Availability Zones.

Question #731 / 1019

Question #252 / 529

A company operates an Amazon Aurora PostgreSQL DB cluster in a single AWS Region. The compliance team needs to continuously audit all data access and modification activities across all databases.

Which solution will meet this requirement?

A

Configure an AWS DMS CDC task with the Aurora cluster as the source and Kinesis Data Firehose as the target. Use Firehose to load data into Amazon OpenSearch Service for audit analysis.

B

Activate a database activity stream on the Aurora cluster, which sends events to Amazon EventBridge. Set up a Lambda function triggered by EventBridge to decrypt and store the activities in Amazon S3.

C

Enable a database activity stream on the Aurora cluster, directing the stream to an Amazon Kinesis data stream. Use Amazon Kinesis Data Firehose to consume the stream and store the data in Amazon S3 for auditing purposes.

D

Create an AWS DMS CDC task sourcing from Aurora and targeting Kinesis Data Firehose. Use Firehose to deliver data to Amazon Redshift, then query Redshift for audit logs.

Question #15 / 529

A company uses multiple AWS accounts. The DNS records for internal services are stored in a private hosted zone for Amazon Route 53 in Account X. Applications running in a VPC in Account Y cannot resolve the backend.example.com CNAME record pointing to an Amazon ElastiCache endpoint. The solutions architect verified that the record set was correctly created in Route 53.

Which combination of steps should the solutions architect take to resolve the resolution failure? (Choose two.)

A

Migrate the ElastiCache cluster to the VPC in Account Y. Create a new record set for the cluster's endpoint in the existing private hosted zone.

B

Use a bastion host to access the application instances. Update the /etc/hosts file with the ElastiCache endpoint IP address.

C

Create an authorization in Account X to associate the private hosted zone with the VPC in Account Y.

D

Create a new private hosted zone for example.com in Account Y. Configure Route 53 Resolver inbound endpoints for cross-account DNS queries.

E

Associate the VPC in Account Y with the private hosted zone in Account X. Remove the authorization record in Account X after association.

Sample Questions

Question #554 / 557

A developer has an application running in AWS Account X. The application needs to access an AWS Secrets Manager secret encrypted by an AWS KMS key in AWS Account Y. The application's role has permissions to retrieve the secret from Account Y but cannot decrypt it due to KMS key policies.

The developer must update the KMS key policy in Account Y to allow the role in Account X to decrypt the secret. The solution must follow the principle of least privilege.

Which permissions should be added to the KMS key policy to meet these requirements?

A

kms:Decrypt and kms:DescribeKey

B

secretsmanager:GetSecretValue and secretsmanager:DescribeSecret

C

kms:*

D

secretsmanager:*
