Question #16 / 1019

A company is building a reporting system using their data lake on AWS, which includes data stored in Amazon S3 and Amazon Aurora PostgreSQL. They need a data visualization solution that integrates all data sources. The security team requires that only the executive team can view all dashboards, while other employees should have access only to specific dashboards based on their department. Which solution meets these requirements?

A

Create an analysis in Amazon QuickSight. Connect all data sources and create datasets. Publish dashboards and share them with the appropriate IAM roles tied to departments and the executive team.

B

Create an analysis in Amazon QuickSight. Connect all data sources and create datasets. Publish dashboards and share them with the appropriate users and groups mapped to departments and the executive team.

C

Use AWS Glue crawlers to catalog the data in Amazon S3. Create an AWS Glue ETL job to generate reports. Store the reports in Amazon S3 and use bucket policies to restrict access based on departments and executive roles.

D

Use AWS Glue crawlers for Amazon S3 data and Amazon Athena Federated Query for Aurora PostgreSQL. Generate reports using Athena, store them in Amazon S3, and control access with bucket policies for departments and executives.

Question #297 / 1019

A company hosts a web application on four Amazon EC2 instances fronted by an Application Load Balancer (ALB) using a target group. The average CPU utilization across the instances hovers around 20%, with intermittent spikes up to 60%. A solutions architect must design an auto-scaling solution that minimizes costs while ensuring adequate CPU resources during traffic spikes. Which solution fulfills these requirements?

A

Create a CloudWatch alarm that triggers when CPUUtilization drops below 25%. Configure an AWS Lambda function invoked by the alarm to terminate an EC2 instance in the target group.

B

Create an EC2 Auto Scaling group linked to the existing ALB and target group. Configure a target tracking scaling policy using the ASGAverageCPUUtilization metric. Set the minimum instances to 2, desired capacity to 4, maximum instances to 7, and target value to 40%. Add the existing EC2 instances to the Auto Scaling group.

C

Create an EC2 Auto Scaling group associated with the existing ALB and target group. Set the minimum instances to 2, desired capacity to 4, and maximum instances to 7. Do not configure a scaling policy. Add the EC2 instances to the Auto Scaling group.

D

Create two CloudWatch alarms: one triggering when average CPUUtilization is below 25% and another when it exceeds 60%. Configure both alarms to publish to an SNS topic for email notifications. Manually adjust the number of EC2 instances after receiving alerts.

Question #150 / 529

A real-time multiplayer gaming platform uses Amazon DynamoDB as its backend database, configured in on-demand capacity mode. The development team needs to optimize the platform for minimal latency while ensuring high availability. Which solution meets these requirements with the LEAST latency?

A

Create a two-node DynamoDB Accelerator (DAX) cluster. Configure the application to read and write data by using DAX.

B

Create a three-node DynamoDB Accelerator (DAX) cluster. Configure the application to read data by using DAX and to write data directly to the DynamoDB table.

C

Create a single-node DynamoDB Accelerator (DAX) cluster. Configure the application to read data by using DAX and to write data directly to the DynamoDB table.

D

Create a three-node DynamoDB Accelerator (DAX) cluster. Configure the application to read and write data by using DAX.

Question #37 / 529

A company is migrating a three-tier Java web application from an on-premises environment to AWS after experiencing downtime due to a traffic surge. The application has a dependency on a PostgreSQL database. A solutions architect must design a scalable and highly available solution to support 250,000 daily users. Which steps should the solutions architect take?

D

Use Amazon EC2 instances in an Auto Scaling group behind a Network Load Balancer (NLB) deployed across two Availability Zones for the web tier. Use Amazon RDS for PostgreSQL in a Single-AZ configuration with automated backups enabled. Configure an Amazon Route 53 weighted routing policy to distribute traffic between EC2 instances.

A

Use AWS Elastic Beanstalk to deploy the web tier with an environment configured with an Application Load Balancer (ALB) and an Amazon EC2 Auto Scaling group across two Availability Zones. Provision an Amazon RDS PostgreSQL Multi-AZ DB instance. Configure an Amazon Route 53 alias record to route traffic from the company\u2019s domain to the ALB.

B

Use AWS CloudFormation to deploy a stack that includes an Application Load Balancer (ALB) in front of an Amazon EC2 Auto Scaling group spanning three Availability Zones. The stack provisions a Multi-AZ Amazon Aurora PostgreSQL DB cluster with a Retain deletion policy. Use an Amazon Route 53 alias record to direct traffic from the company\u2019s domain to the ALB.

C

Use AWS Elastic Beanstalk to create a web server environment spanning two AWS Regions, each with an Application Load Balancer (ALB). Deploy a Multi-AZ Amazon Aurora PostgreSQL DB cluster with a cross-Region read replica. Use Amazon Route 53 with a latency-based routing policy to distribute traffic between the two Regions.

Question #174 / 557

A developer needs to create and delete tags for repositories in AWS CodeCommit. The current IAM policy for the user is:

json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "codecommit:GetRepository", "codecommit:ListRepositories", "codecommit:GitPull" ], "Resource": "*" } ] } 

Which specific IAM permissions must be added, following the principle of least privilege?

A

\"codecommit:TagResource\", \"codecommit:UntagResource\"

B

\"codecommit:Put*\"

C

\"codecommit:UpdateRepository\"

D

\"codecommit:*\"

Question #294 / 557

A company's developer deployed an application using AWS CloudFormation, which includes an S3 bucket configured with CORS settings. The application can modify the bucket's CORS configuration. During a stack update to add new IAM roles, the developer noticed the CORS settings reverted to their original values, overwriting the application's changes. The developer needs to prevent this while minimizing development effort.

Which solution will meet these requirements with the LEAST development effort?

A

Modify the CloudFormation stack to set the DeletionPolicy to Retain for the S3 bucket.

B

Create an Amazon DynamoDB table in the stack to store CORS configurations. Update the application to use DynamoDB instead of the S3 bucket's CORS settings.

C

Use an Amazon RDS instance to store CORS configurations. Update the application to retrieve settings from RDS.

D

Modify the CloudFormation stack policy to deny updates to the S3 bucket's CORS configuration.
