A company uses NFS to store large video files in on-premises network attached storage. Each video file ranges in size from 1 MB to 500 GB. The total storage is 70 TB and is no longer growing. The company decides to migrate the video files to Amazon S3. The company must migrate the video files as soon as possible while using the least possible network bandwidth.

Which solution will meet these requirements?

A.

Create an S3 bucket. Create an IAM role that has permissions to write to the S3 bucket. Use the AWS CLI to copy all files locally to the S3 bucket.

B.

Create an AWS Snowball Edge job. Receive a Snowball Edge device on premises. Use the Snowball Edge client to transfer data to the device. Return the device so that AWS can import the data into Amazon S3.

C.

Deploy an S3 File Gateway on premises. Create a public service endpoint to connect to the S3 File Gateway. Create an S3 bucket. Create a new NFS file share on the S3 File Gateway. Point the new file share to the S3 bucket. Transfer the data from the existing NFS file share to the S3 File Gateway.

D.

Set up an AWS Direct Connect connection between the on-premises network and AWS. Deploy an S3 File Gateway on premises. Create a public virtual interface (VIF) to connect to the S3 File Gateway. Create an S3 bucket. Create a new NFS file share on the S3 File Gateway. Point the new file share to the S3 bucket. Transfer the data from the existing NFS file share to the S3 File Gateway.

Correct Answer: B

To migrate 70 TB of video files from on-premises storage to Amazon S3 while using the least possible network bandwidth, using AWS Snowball Edge is the most suitable option. AWS Snowball Edge is a physical data transport solution that can transfer large amounts of data securely and quickly without utilizing internet bandwidth. The process involves receiving the Snowball Edge device at the premises, transferring the data to the device using the Snowball Edge client, and then shipping the device back to AWS, where the data is imported into Amazon S3. This approach minimizes network bandwidth usage and ensures a rapid transfer given the volume of data.

Question 7 of 904

A company has an application that ingests incoming messages. Dozens of other applications and microservices then quickly consume these messages. The number of messages varies drastically and sometimes increases suddenly to 100,000 each second. The company wants to decouple the solution and increase scalability.

Which solution meets these requirements?

A.

Persist the messages to Amazon Kinesis Data Analytics. Configure the consumer applications to read and process the messages.

B.

Deploy the ingestion application on Amazon EC2 instances in an Auto Scaling group to scale the number of EC2 instances based on CPU metrics.

C.

Write the messages to Amazon Kinesis Data Streams with a single shard. Use an AWS Lambda function to preprocess messages and store them in Amazon DynamoDB. Configure the consumer applications to read from DynamoDB to process the messages.

D.

Publish the messages to an Amazon Simple Notification Service (Amazon SNS) topic with multiple Amazon Simple Queue Service (Amazon SOS) subscriptions. Configure the consumer applications to process the messages from the queues.

Correct Answer: D

The solution that best meets the company's requirements of ingesting and quickly consuming up to 100,000 messages each second while decoupling the solution and increasing scalability is to publish messages to an Amazon Simple Notification Service (Amazon SNS) topic with multiple Amazon Simple Queue Service (Amazon SQS) subscriptions. This configuration provides a scalable and decoupled architecture as Amazon SNS can handle high message throughput and enables multiple consumer applications to process the messages in parallel through SQS. This approach ensures that the system can handle drastic variations in message volume efficiently.

Question 8 of 904

A company is migrating a distributed application to AWS. The application serves variable workloads. The legacy platform consists of a primary server that coordinates jobs across multiple compute nodes. The company wants to modernize the application with a solution that maximizes resiliency and scalability.

How should a solutions architect design the architecture to meet these requirements?

A.

Configure an Amazon Simple Queue Service (Amazon SQS) queue as a destination for the jobs. Implement the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure EC2 Auto Scaling to use scheduled scaling.

B.

Configure an Amazon Simple Queue Service (Amazon SQS) queue as a destination for the jobs. Implement the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure EC2 Auto Scaling based on the size of the queue.

C.

Implement the primary server and the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure AWS CloudTrail as a destination for the jobs. Configure EC2 Auto Scaling based on the load on the primary server.

D.

Implement the primary server and the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure Amazon EventBridge (Amazon CloudWatch Events) as a destination for the jobs. Configure EC2 Auto Scaling based on the load on the compute nodes.

Correct Answer: B

To address the variable workloads and maximize both resiliency and scalability, the best approach involves using Amazon Simple Queue Service (Amazon SQS) as a buffer for the jobs. This decouples the primary server from the compute nodes, making the system more resilient. By implementing the compute nodes with EC2 instances managed by an Auto Scaling group and configuring scaling based on the size of the SQS queue, the system can dynamically adjust the number of instances according to the workload. This ensures that the infrastructure scales out to handle peak loads and scales in during periods of lower activity, providing cost efficiency and enhancing responsiveness to workload changes.

Question 9 of 904

A company is running an SMB file server in its data center. The file server stores large files that are accessed frequently for the first few days after the files are created. After 7 days the files are rarely accessed.

The total data size is increasing and is close to the company's total storage capacity. A solutions architect must increase the company's available storage space without losing low-latency access to the most recently accessed files. The solutions architect must also provide file lifecycle management to avoid future storage issues.

Which solution will meet these requirements?

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 extend 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 for Windows File Server file system to extend the company's storage space.

D.

Install a utility on each user's computer to access Amazon S3. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.

Correct Answer: B

Create an Amazon S3 File Gateway to extend the company's storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days. This solution provides seamless integration with existing SMB file servers and allows for the extension of storage capacity using Amazon S3. Additionally, the S3 Lifecycle policy ensures that data is automatically transitioned to a cost-effective storage class after 7 days, managing storage efficiently while maintaining low-latency access for recently accessed files due to the gateway's local caching capabilities.

Question 10 of 904

A company is building an ecommerce web application on AWS. The application sends information about new orders to an Amazon API Gateway REST API to process. The company wants to ensure that orders are processed in the order that they are received.

Which solution will meet these requirements?

A.

Use an API Gateway integration to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when the application receives an order. Subscribe an AWS Lambda function to the topic to perform processing.

B.

Use an API Gateway integration to send a message to an Amazon Simple Queue Service (Amazon SQS) FIFO queue when the application receives an order. Configure the SQS FIFO queue to invoke an AWS Lambda function for processing.

C.

Use an API Gateway authorizer to block any requests while the application processes an order.

D.

Use an API Gateway integration to send a message to an Amazon Simple Queue Service (Amazon SQS) standard queue when the application receives an order. Configure the SQS standard queue to invoke an AWS Lambda function for processing.

Correct Answer: B

To ensure that orders are processed in the order they are received, the company should use an Amazon Simple Queue Service (SQS) FIFO (First-In-First-Out) queue. SQS FIFO queues are specifically designed to guarantee the order of message processing and exactly-once delivery. By integrating the API Gateway to send messages to an SQS FIFO queue and configuring the queue to invoke an AWS Lambda function for processing, the company can ensure that order processing maintains the sequence in which the orders were received.
