Question 1

A cloud-based video surveillance company is developing an application that analyzes video files. After theapplication analyzes the files, the company can discard the files.The company stores the files in an Amazon S3 bucket. The files are 1 GB in size on average. No file is largerthan 2 GB. An AWS Lambda function will run one time for each video file that is processed. The processingis very I/O intensive, and the application must read each file multiple times.Which solution will meet these requirements in the MOST performance-optimized way?

A : Attach an Amazon EBS volume that is larger than 1 GB to the Lambda function. Copy the files fromthe S3 bucket to the EBS volume.

B : Attach an Elastic Network Adapter (ENA) to the Lambda function. Use the ENA to read the video filesfrom the S3 bucket.

C : Increase the ephemeral storage size to 2 GB. Copy the files from the S3 bucket to the /tmp directory ofthe Lambda function.

D : Configure the Lambda function code to read the video files directly from the S3 bucket.

Answer: C

Question 2

A developer needs to use Amazon DynamoDB to store customer orders. The developer ' s company requiresall customer data to be encrypted at rest with a key that the company generates.What should the developer do to meet these requirements?

B : Store the key by using AW5 KMS. Choose an AVVS KMS customer managed key during creation ofthe DynamoDB table. Provide the Amazon Resource Name (ARN) of the AWS KMS key.

C : Store the key by using AWS KMS. Create the DynamoDB table with default encryption. Include thekms:Encrypt parameter with the Amazon Resource Name (ARN) of the AWS KMS key when using theDynamoDB SDK.

Question 3

A social media company is designing a platform that allows users to upload data, which is stored in AmazonS3. Users can upload data encrypted with a public key. The company wants to ensure that only the companycan decrypt the uploaded content using an asymmetric encryption key. The data must always be encrypted intransit and at rest.Options:

A : Use server-side encryption with Amazon S3 managed keys (SSE-S3) to encrypt the data.

B : Use server-side encryption with customer-provided encryption keys (SSE-C) to encrypt the data.

C : Use client-side encryption with a data key to encrypt the data.

D : Use client-side encryption with a customer-managed encryption key to encrypt the data.

Answer: D

Question 4

A developer needs to create a serverless application that uses an event-driven architecture.

How can the developer configure the application to automatically receive and process events?

A : eate an Amazon SQS queue and publish events to the queue. Configure an Amazon EC2 instance to poll the queue and consume the messages.

B : eate an Amazon SQS topic and an Amazon EC2 instance. Subscribe the instance to the SNS topic and submit events to the topic.

C : Create an Amazon SNS topic and an AWS Lambda function. Configure an HTTP endpoint on the Lambda function and subscribe the HTTP endpoint to the SNS topic. Submit events to the SNS topic.

D : eate an Amazon SNS topic and an AWS Lambda function. Subscribe the Lambda function to the SNS topic and submit events to the SNS topic.

Answer: D
