Question 1

A research laboratory needs to process approximately 8 TB of data. The laboratory requires sub-millisecond latencies and a minimum throughput of 6 GBps for the storage subsystem. Hundreds of Amazon EC2 instances that run Amazon Linux will distribute and process the data.Which solution will meet the performance requirements?

Options :

A : Create an Amazon FSx for NetApp ONTAP file system Set each volume-s tiering policy to ALL Import the raw data into the file system Mount the file system on the EC2 instances

B : Create an Amazon S3 bucket to stofe the raw data Create an Amazon FSx for Lustre file system that uses persistent SSD storage Select the option to import data from and export data to Amazon S3 Mount the file system on the EC2 instances

C : Create an Amazon S3 bucket to store the raw data Create an Amazon FSx for Lustre file system that uses persistent HDD storage Select the option to import data from and export data to Amazon S3 Mount the file system on the EC2 instances

D : Create an Amazon FSx for NetApp ONTAP file system Set each volume-s tienng policy to NONE. Import the raw data into the file system Mount the file system on the EC2 instances

Answer: B

Question 2

A company sells datasets to customers who do research in artificial intelligence and machine learning (Al/ML) The datasets are large, formatted files that are stored in an Amazon S3 bucket in the us-east-1 Region The company hosts a web application that the customers use to purchase access to a given dataset The web application is deployed on multiple Amazon EC2 instances behind an Application Load Balancer After a purchase is made customers receive an S3 signed URL that allows access to the files.The customers are distributed across North America and Europe The company wants to reduce the cost that is associated with data transfers and wants to maintain or improve performance.What should a solutions architect do to meet these requirements?

Options :

A : Configure S3 Transfer Acceleration on the existing S3 bucket Direct customer requests to the S3 Transfer Acceleration endpoint Continue to use S3 signed URLs for access control

B : Deploy an Amazon CloudFront distribution with the existing S3 bucket as the origin Direct customer requests to the CloudFront URL Switch to CloudFront signed URLs for access control

C : Set up a second S3 bucket in the eu-central-1 Region with S3 Cross-Region Replication between the buckets Direct customer requests to the closest Region Continue to use S3 signed URLs for access control

D : Modify the web application to enable streaming of the datasets to end users. Configure the web application to read the data from the existing S3 bucket Implement access control directly in the application

Answer: B

Question 3

A company runs an application that uses Amazon RDS for PostgreSQL The application receives traffic only on weekdays during business hours The company wants to optimize costs and reduce operational overhead based on this usage. Which solution will meet these requirements?

Options :

A : Use the Instance Scheduler on AWS to configure start and stop schedules.

B : Turn off automatic backups. Create weekly manual snapshots of the database.

C : Create a custom AWS Lambda function to start and stop the database based on minimum CPU utilization.

D : Purchase All Upfront reserved DB instances.

Answer: A

Question 4

A company runs a critical, customer-facing application on Amazon Elastic Kubernetes Service (Amazon EKS). The application has a microservices architecture. The company needs to implement a solution that collects, aggregates, and summarizes metrics and logs from the application in a centralized location.

Which solution meets these requirements?

Options :

A : Run the Amazon CloudWatch agent in the existing EKS cluster. View the metrics and logs in the CloudWatch console.

B : Run AWS App Mesh in the existing EKS cluster. View the metrics and logs in the App Mesh console.

C : Configure AWS CloudTrail to capture data events. Query CloudTrail by using Amazon OpenSearch Service.

D : Configure Amazon CloudWatch Container Insights in the existing EKS cluster. View the metrics and logs in the CloudWatch console.

Answer: D

Question 5

A company wants to share accounting data with an external auditor. The data is stored in an Amazon RDS DB instance that resides in a private subnet. The auditor has its own AWS account and requires its own copy of the database. What is the MOST secure way for the company to share the database with the auditor?

Options :

A : Create a read replica of the database. Configure IAM standard database authentication to grant the auditor access.

B : Export the database contents to text files. Store the files in an Amazon S3 bucket. Create a new IAM user for the auditor. Grant the user access to the S3 bucket.

C : Copy a snapshot of the database to an Amazon S3 bucket. Create an IAM user. Share the user-s keys with the auditor to grant access to the object in the $3 bucket.

D : Create an encrypted snapshot of the database. Share the snapshot with the auditor. Allow access to the AWS Key Management Service (AWS KMS) encryption key.
