Topic 1 - Exam A

Topic 1

Question #1

A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple continents. The average volume of data

that the company collects from each site daily is 500 GB. Each site has a high-speed Internet connection.

The company wants to aggregate the data from all these global sites as quickly as possible in a single Amazon S3 bucket. The solution must

minimize operational complexity.

Which solution meets these requirements?

A. Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3

bucket.

B. Upload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3

bucket. Then remove the data from the origin S3 bucket.

C. Schedule AWS Snowball Edge Storage Optimized device jobs daily to transfer data from each site to the closest Region. Use S3 Cross-

Region Replication to copy objects to the destination S3 bucket.

D. Upload the data from each site to an Amazon EC2 instance in the closest Region. Store the data in an Amazon Elastic Block Store (Amazon

EBS) volume. At regular intervals, take an EBS snapshot and copy it to the Region that contains the destination S3 bucket. Restore the EBS

volume in that Region.

Question #2

A company needs the ability to analyze the log les of its proprietary application. The logs are stored in JSON format in an Amazon S3 bucket.

Queries will be simple and will run on-demand. A solutions architect needs to perform the analysis with minimal changes to the existing

architecture.

What should the solutions architect do to meet these requirements with the LEAST amount of operational overhead?

A. Use Amazon Redshift to load all the content into one place and run the SQL queries as needed.

B. Use Amazon CloudWatch Logs to store the logs. Run SQL queries as needed from the Amazon CloudWatch console.

C. Use Amazon Athena directly with Amazon S3 to run the queries as needed.

D. Use AWS Glue to catalog the logs. Use a transient Apache Spark cluster on Amazon EMR to run the SQL queries as needed.

Question #5

A company is hosting a web application on AWS using a single Amazon EC2 instance that stores user-uploaded documents in an Amazon EBS

volume. For better scalability and availability, the company duplicated the architecture and created a second EC2 instance and EBS volume in

another Availability Zone, placing both behind an Application Load Balancer. After completing this change, users reported that, each time they

refreshed the website, they could see one subset of their documents or the other, but never all of the documents at the same time.

What should a solutions architect propose to ensure users see all of their documents at once?

A. Copy the data so both EBS volumes contain all the documents

B. Congure the Application Load Balancer to direct a user to the server with the documents

C. Copy the data from both EBS volumes to Amazon EFS. Modify the application to save new documents to Amazon EFS

D. Congure the Application Load Balancer to send the request to both servers. Return each document from the correct server

Question #6

A company uses NFS to store large video les in on-premises network attached storage. Each video le 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 les to Amazon S3. The company must migrate the

video les 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 les 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 le share on the S3 File Gateway. Point the new le share to the S3 bucket. Transfer the data from the existing NFS le 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 le share on the S3 File Gateway. Point

the new le share to the S3 bucket. Transfer the data from the existing NFS le share to the S3 File Gateway.

Question #7

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. Congure 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. Congure the consumer applications to read from DynamoDB to process the messages.

D. Publish the messages to an Amazon Simple Notication Service (Amazon SNS) topic with multiple Amazon Simple Queue Service (Amazon

SOS) subscriptions. Congure the consumer applications to process the messages from the queues.

Question #9

A company is running an SMB le server in its data center. The le server stores large les that are accessed frequently for the rst few days after

the les are created. After 7 days the les 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 les. The solutions architect must also provide le 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 le 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 le 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.
