Question 20

A company needs a data encryption solution for a machine learning (ML) process. The solution must use an AWS managed service. The ML process currently reads a large number of objects in Amazon S3 that are encrypted by a customer managed AWS KMS key. The current process incurs significant costs because of excessive calls to AWS Key Management Service (AWS KMS) to decrypt S3 objects. The company wants to reduce the costs of API calls to decrypt S3 objects.

Options:

Switch from a customer managed KMS key to an AWS managed KMS key.

Remove the AWS KMS encryption from the S3 bucket. Use a bucket policy to encrypt the data instead.

Recreate the KMS key in AWS CloudHSM.

Use S3 Bucket Keys to perform server-side encryption with AWS KMS keys (SSE-KMS) to encrypt and decrypt objects from Amazon S3.

Question 21

A solutions architect wants to design a data warehouse by using an Amazon Redshift cluster in the eu-west-1 Region. The data warehouse will initially ingest data from Amazon DynamoDB tables in eu-west-1. The VPC that the Redshift cluster will be deployed in must not connect to the internet.

Which solution will securely load data MOST cost-effectively?

Options:

Create a DynamoDB gateway VPC endpoint within the VPC. Add a route from the VPC subnets to the DynamoDB prefix list by using the gateway endpoint. Add a resource policy to the endpoint to allow the Redshift cluster to access the specific workload tables.

Create a DynamoDB interface VPC endpoint within the VPC. Add a route from the VPC subnets to the DynamoDB prefix list by using the interface endpoint. Configure the security group of the interface endpoint to allow connections from the Redshift cluster VPC.

Deploy a DynamoDB interface VPC endpoint within the VPC. Enable private DNS resolution for the endpoint. Enable the interface endpoint in all data warehouse Availability Zones.

Deploy a VPC peering connection to the DynamoDB VPC. Add a route from the VPC subnets to the DynamoDB CIDR range by using the peering connection. Add a return route from the DynamoDB VPC to the Redshift cluster VPC.

Question 22

A company has an application that processes information from documents that users upload. When a user uploads a new document to an Amazon S3 bucket, an AWS Lambda function is invoked. The Lambda function processes information from the documents.

The company discovers that the application did not process many recently uploaded documents. The company wants to ensure that the application processes each document with retries if there is an error during the first attempt to process the document.

Which solution will meet these requirements?

Options:

Create an Amazon API Gateway REST API that has a proxy integration to the Lambda function. Update the application to send requests to the REST API.

Configure a replication policy on the S3 bucket to stage the documents in another S3 bucket that an AWS Batch job processes on a daily schedule.

Deploy an Application Load Balancer in front of the Lambda function that processes the documents.

Configure an Amazon Simple Queue Service (Amazon SQS) queue as an event source for the Lambda function. Configure an S3 event notification on the S3 bucket to send new document upload events to the SQS queue.

Madeleine

Passed my exam with my dream score…. Guys do give these dumps a try. They are authentic.

Ziggy Jun 8, 2026

That's really impressive. I think I might give Cramkey Dumps a try for my next certification exam.

Question 23

A large financial services company uses Amazon ElastiCache (Redis OSS) for its new application that has a global user base. A solutions architect must develop a caching solution that will be available across AWS Regions and include low-latency replication and failover capabilities for disaster recovery (DR). The company ' s security team requires the encryption of cross-Region data transfers.

Which solution meets these requirements with the LEAST amount of operational effort?

Options:

Enable cluster mode in ElastiCache (Redis OSS). Then create multiple clusters across Regions and replicate the cache data by using AWS Database Migration Service (AWS DMS). Promote a cluster in the failover Region to handle production traffic when DR is required.

Create a global data store in ElastiCache (Redis OSS).Then create replica clusters in two other Regions. Promote one of the replica clusters as primary when DR is required.

Disable cluster mode in ElastiCache (Redis OSS). Then create multiple replication groups across Regions and replicate the cache data by using AWS Database Migration Service (AWS DMS). Promote a replication group in the failover Region to primary when DR is required.

Create a snapshot of ElastiCache (Redis OSS) in the primary Region and copy it to the failover Region. Use the snapshot to restore the cluster from the failover Region when DR is required.
