Question 1

A company hosts an application used to upload files to an Amazon S3 bucket Onceuploaded, the files are processed to extract metadata which takes less than 5 seconds Thevolume and frequency of the uploads varies from a few files each hour to hundreds ofconcurrent uploads The company has asked a solutions architect to design a cost-effectivearchitecture that will meet these requirements.What should the solutions architect recommend?

A. Configure AWS CloudTrail trails to tog S3 API calls Use AWS AppSync to process thefiles.

B. Configure an object-created event notification within the S3 bucket to invoke an AWSLambda function to process the files.

C. Configure Amazon Kinesis Data Streams to process and send data to Amazon S3.Invoke an AWS Lambda function to process the files.

D. Configure an Amazon Simple Notification Service (Amazon SNS) topic to process thefiles uploaded to Amazon S3 Invoke an AWS Lambda function to process the files.

Answer: B

Question 2

A company runs analytics software on Amazon EC2 instances The software accepts jobrequests from users to process data that has been uploaded to Amazon S3 Users reportthat some submitted data is not being processed Amazon CloudWatch reveals that theEC2 instances have a consistent CPU utilization at or near 100% The company wants toimprove system performance and scale the system based on user load.What should a solutions architect do to meet these requirements?

A. Create a copy of the instance Place all instances behind an Application Load Balancer

B. Create an S3 VPC endpoint for Amazon S3 Update the software to reference theendpoint

C. Stop the EC2 instances. Modify the instance type to one with a more powerful CPU andmore memory. Restart the instances.

D. Route incoming requests to Amazon Simple Queue Service (Amazon SQS) Configurean EC2 Auto Scaling group based on queue size Update the software to read from the queue.

Answer: D

Question 3

A company is deploying an application that processes streaming data in near-real time Thecompany plans to use Amazon EC2 instances for the workload The network architecturemust be configurable to provide the lowest possible latency between nodesWhich combination of network solutions will meet these requirements? (Select TWO)

A. Enable and configure enhanced networking on each EC2 instance

B. Group the EC2 instances in separate accounts

C. Run the EC2 instances in a cluster placement group

D. Attach multiple elastic network interfaces to each EC2 instance

E. Use Amazon Elastic Block Store (Amazon EBS) optimized instance types.

Answer: A,C

Question 4

A company runs a container application on a Kubernetes cluster in the company's datacenter The application uses Advanced Message Queuing Protocol (AMQP) tocommunicate with a message queue The data center cannot scale fast enough to meet thecompany's expanding business needs The company wants to migrate the workloads toAWSWhich solution will meet these requirements with the LEAST operational overhead? \

A. Migrate the container application to Amazon Elastic Container Service (Amazon ECS)Use Amazon Simple Queue Service (Amazon SQS) to retrieve the messages.

B. Migrate the container application to Amazon Elastic Kubernetes Service (Amazon EKS)Use Amazon MQ to retrieve the messages.

C. Use highly available Amazon EC2 instances to run the application Use Amazon MQ toretrieve the messages.

D. Use AWS Lambda functions to run the application Use Amazon Simple Queue Service(Amazon SQS) to retrieve the messages.

Answer: B

Question 5

A company runs a real-time data ingestion solution on AWS. The solution consists of themost recent version of Amazon Managed Streaming for Apache Kafka (Amazon MSK). Thesolution is deployed in a VPC in private subnets across three Availability Zones.A solutions architect needs to redesign the data ingestion solution to be publicly availableover the internet. The data in transit must also be encrypted.Which solution will meet these requirements with the MOST operational efficiency?

A. Configure public subnets in the existing VPC. Deploy an MSK cluster in the publicsubnets. Update the MSK cluster security settings to enable mutual TLS authentication.

B. Create a new VPC that has public subnets. Deploy an MSK cluster in the publicsubnets. Update the MSK cluster security settings to enable mutual TLS authentication.

C. Deploy an Application Load Balancer (ALB) that uses private subnets. Configure an ALBsecurity group inbound rule to allow inbound traffic from the VPC CIDR block for HTTPSprotocol.

D. Deploy a Network Load Balancer (NLB) that uses private subnets. Configure an NLBlistener for HTTPS communication over the internet.

Answer: A
