Question #241 / 1019

A global e-commerce platform uses a PostgreSQL database to manage real-time inventory data. The platform requires continuous availability of its database across multiple AWS Regions with minimal operational complexity. Which solution fulfills these requirements?

A

Deploy a PostgreSQL cluster on Amazon EC2 instances across multiple Regions using a custom replication setup.

B

Use Amazon RDS for PostgreSQL with Multi-AZ deployment enabled in a single Region.

C

Configure an Amazon RDS for PostgreSQL primary instance and create a cross-Region read replica in another AWS Region.

D

Implement automated backups of an Amazon RDS for PostgreSQL instance and copy backups to a secondary Region.

Question #725 / 1019

A company stores approximately 400 TB of data in Amazon S3 Standard storage monthly. The S3 objects average 75 GB in size and are regularly overwritten using multipart uploads by their worldwide application. While the total number and size of objects remain consistent, the company observes a steady monthly rise in S3 storage costs.

What should a solutions architect recommend to address the cost increase?

A

Replace multipart uploads with AWS Snowball for data transfers.

B

Implement an S3 Lifecycle policy to expire incomplete multipart uploads.

C

Use S3 Intelligent-Tiering to automatically optimize storage costs.

D

Set up S3 Cross-Region Replication to reduce regional storage overhead.

Sample Questions

Question #43 / 529

A company is using Amazon OpenSearch Service to store and analyze application logs. The company ingests logs into an OpenSearch Service cluster with 12 data nodes from an Amazon S3 bucket that uses S3 Standard-Infrequent Access (S3 Standard-IA). The logs remain in the cluster for 6 months for analysis, after which the company deletes the indexes. Compliance regulations require the company to retain all logs for 5 years. The company wants to minimize costs while meeting compliance requirements.

Which solution will meet these requirements MOST cost-effectively?

A

Replace all data nodes with UltraWarm nodes to handle the logging workload. Transition the input logs from S3 Standard-IA to S3 Glacier Deep Archive immediately upon ingestion into the cluster.

B

Reduce the number of data nodes in the cluster to 3. Add UltraWarm nodes to handle the logging workload. Configure indexes to transition to UltraWarm during ingestion. Apply an S3 Lifecycle policy to transition the input logs to S3 Glacier Deep Archive 6 months after ingestion.

C

Reduce the number of data nodes in the cluster to 3. Use instance-backed storage for the remaining data nodes. Transition the input logs from S3 Standard-IA to S3 Glacier Deep Archive immediately upon ingestion into the cluster.

D

Reduce the number of data nodes in the cluster to 3. Add UltraWarm nodes and cold storage nodes to the cluster. Configure indexes to transition from UltraWarm to cold storage after 6 months. Delete the input logs from S3 using an S3 Lifecycle policy after 6 months.

Question #256 / 529

A company stores millions of objects in an Amazon S3 bucket using the S3 Standard storage class. All objects are accessed frequently by a growing number of users and applications. The objects are encrypted using server-side encryption with AWS KMS keys (SSE-KMS). The company observes a significant increase in AWS KMS costs due to the high volume of encryption requests from S3. A solutions architect must reduce costs while minimizing application changes.

Which solution meets these requirements with the LEAST operational overhead?

A

Create a new S3 bucket configured for server-side encryption with customer-provided keys (SSE-C). Use S3 Batch Operations to copy existing objects to the new bucket and apply SSE-C encryption.

B

Create a new S3 bucket configured for server-side encryption with Amazon S3 managed keys (SSE-S3). Use S3 Batch Operations to copy existing objects to the new bucket and apply SSE-S3 encryption.

C

Migrate encryption keys to AWS CloudHSM. Create a new S3 bucket and use S3 Batch Operations to copy objects while encrypting them with CloudHSM-managed keys.

D

Transition the S3 bucket to the S3 Intelligent-Tiering storage class. Configure an archive policy to move objects not accessed for 30 days to S3 Glacier Instant Retrieval.

Sample Questions

Question #117 / 557

A developer maintains a critical business application that uses Amazon DynamoDB as the primary data store. The DynamoDB table processes thousands of transactions per second and requires immediate notifications whenever items are modified. The developer needs to send email alerts whenever updates occur, with the LEAST amount of change to the existing application code.

How can the developer implement this feature most efficiently?

A

Configure an Amazon CloudWatch alarm to monitor write operations. Use Amazon SNS to send emails when the alarm triggers.

B

Enable a DynamoDB stream on the table. Use an AWS Lambda function to process the stream records and send notifications via Amazon SNS.

C

Modify the application to publish an event to an Amazon SQS queue after each write. Use a Lambda function to poll the queue and send emails.

D

Update the application to directly invoke Amazon SES to send emails immediately after each DynamoDB write operation.

Question #207 / 557

A developer is designing a serverless application that interacts with an Amazon RDS MySQL database. The application uses numerous AWS Lambda functions that trigger frequent scale-outs, each establishing a new database connection and straining database resources. The developer needs to minimize the number of database connections while ensuring Lambda functions can scale seamlessly. Which solution meets these requirements?

A

Set up provisioned concurrency for each Lambda function with ProvisionedConcurrentExecutions set to 20.

B

Enable query caching in RDS MySQL and update Lambda connection strings to use the cache endpoint.

C

Utilize Amazon RDS Proxy to manage database connections through pooling, adjusting Lambda connection strings to the proxy.

D

Apply reserved concurrency for each Lambda function, setting ReservedConcurrentExecutions to 20.
