A : Store the uploaded documents in an Amazon S3 bucket with S3 Versioning and S3 Object Lock enabled.

B :

Store the uploaded documents in an Amazon S3 bucket. Configure an S3 Lifecycle policy to archive the documents periodically

C :

Store the uploaded documents in an Amazon S3 bucket with S3 Versioning enabled. Configure an ACL to restrict all access to read-only.

Store the uploaded documents on an Amazon Elastic File System (Amazon EFS) volume. Access the data by mounting the volume in read-only mode

Answer: A

Question 2

A weather forecasting company needs to process hundreds of gigabytes of data with sub-millisecond latency. The company has a high performance computing (HPC) environment in its data center and wants to expand its forecasting capabilities.A solutions architect must identify a highly available cloud storage solution that can handle large amounts of sustained throughput. Files that are stored in the solution should be accessible to thousands of compute instances that will simultaneously access and process the entire dataset.What should the solutions architect do to meet these requirements?

Options :

A : Use Amazon FSx for Lustre scratch file systems.

B : Use Amazon FSx for Lustre persistent file systems.

C : Use Amazon Elastic File System (Amazon EFS) with Bursting Throughput mode.

D : Use Amazon Elastic File System (Amazon EFS) with Provisioned Throughput mode.

Answer: B

Question 3

A company has a running m5ad.large EC2 instance with a default attached 75 GB SSD instance-store backed volume. You shut it down and then start the instance. You noticed that the data which you have saved earlier on the attached volume is no longer available.

What might be the cause of this?

Options :

A :

The EC2 instance was using instance store volumes, which are ephemeral and only live for the life of the instance.

B : The volume of the instance was not big enough to handle all of the processing data.

C : The instance was hit by a virus that wipes out all data.

D : The EC2 instance was using EBS backed root volumes, which are ephemeral and only live for the life of the instance.

Answer: A

Question 4

A company is building a solution that will report Amazon EC2 Auto Scaling events across all the applications in an AWS account. The company needs to use a serverless solution to store the EC2 Auto Scaling status data in Amazon S3. The company then will use the data in Amazon S3 to provide near-real-time updates in a dashboard. The solution must not affect the speed of EC2 instance launches.How should the company move the data to Amazon S3 to meet these requirements?

Options :

A : Use an Amazon CloudWatch metric stream to send the EC2 Auto Scaling status data to Amazon Kinesis Data Firehose. Store the data in Amazon S3.

B : Launch an Amazon EMR cluster to collect the EC2 Auto Scaling status data and send the data to Amazon Kinesis Data Firehose. Store the data in Amazon S3

C : Create an Amazon EventBridge rule to invoke an AWS Lambda function on a schedule. Configure the Lambda function to send the EC2 Auto Scaling status data directly to Amazon S3

D : Use a bootstrap script during the launch of an EC2 instance to install Amazon Kinesis Agent. Configure Kinesis Agent to collect the EC2 Auto Scaling status data and send the data to Amazon Kinesis Data Firehose. Store the data in Amazon S3.

Answer: A

Question 5

A company runs an SMB file server in its data center. The file server stores large files that the company frequently accesses for up to 7 days after the file creation date. After 7 days, the company needs to be able to access the files with a maximum retrieval time of 24 hours.Which solution will meet these requirements?

Options :

A : Use AWS DataSync to copy data that is older than 7 days from the SMB file server to AWS.

B : Create an Amazon S3 File Gateway to increase the company-s storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days.

C : Create an Amazon FSx File Gateway to increase the company-s storage space. Create an Amazon S3 Lifecycle policy to transition the data after 7 days.

D : Configure access to Amazon S3 for each user. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.
