A company is hosting a web application from an Amazon S3 bucket. The application uses Amazon Cognito as an identity provider lo authenticate users and return a JSON Web Token (JWT) that provides access to protected resources that am restored in another S3 bucket.
Upon deployment of the application, users report errors and are unable to access the protected content. A solutions architect must resolve this issue by providing proper permissions so that users can access the protected content.
Which solution meets these requirements?
A. Update the Amazon Cognito identity pool to assume the proper IAM role for access to the protected consent.
B. Update the S3 ACL to allow the application to access the protected content.
C. Redeploy the application to Amazon 33 to prevent eventually consistent reads m the S3 bucket from affecting the ability of users to access the protected content.
D. Update the Amazon Cognito pool to use custom attribute mappings within tie Identity pool and grant users the proper permissions to access the protected content
Answer: B
A company wants to restrict access to the content of one of its man web applications and to protect the content by using authorization techniques available on AWS. The company wants to implement a serverless architecture end an authentication solution for fewer tian 100 users. The solution needs to integrate with the main web application and serve web content globally. The solution must also scale as to company's user base grows while providing lowest login latency possible.
A. Use Amazon Cognito tor authentication. Use Lambda#Edge tor authorization Use Amazon CloudFront 10 serve the web application globally
B. Use AWS Directory Service for Microsoft Active Directory tor authentication Use AWS Lambda for authorization Use an Application Load Balancer to serve the web application globally
C. Usa Amazon Cognito for authentication Use AWS Lambda tor authorization Use Amazon S3 Transfer Acceleration 10 serve the web application globally.
D. Use AWS Directory Service for Microsoft Active Directory for authentication Use Lambda@Edge for authorization Use AWS Elastic Beanstalk to serve the web application.
Answer: A
A solutions architect must secure a VPC network that hosts Amazon EC2 instances The EC2 ^stances contain highly sensitive data and tun n a private subnet According to company policy the EC2 instances mat run m the VPC can access only approved thirdparty software repositories on the internet for software product updates that use the third party's URL Other internet traffic must be blocked.
Which solution meets these requirements?
A. Update the route table for the private subnet to route the outbound traffic to an AWS Network Firewall. Configure domain list rule groups
B. Set up an AWS WAF web ACL. Create a custom set of rules that filter traffic requests based on source and destination IP address range sets.
C. Implement strict inbound security group roles Configure an outbound rule that allows traffic only to the authorized software repositories on the internet by specifying the URLs.
D. Configure an Application Load Balancer (ALB) in front of the EC2 instances. Direct an outbound traffic to the ALB Use a URL-based rule listener in the ALB's target group for outbound access to the internet
Answer: C
A company deploys an appliation on five Amazon EC2 instances. An Applicatin Load Balancer (ALB) distributes traffic to the instances by using a target group. The average CPU usage on each of the insatances is below 10% most of the time. With occasional surges to 65%.
A solution architect needs to implement a solution to automate the scalability of the application. The solution must optimize the cost of the architecture and must ensure that the application has enough CPU resources when surges occur.
Which solution will meet these requirements?
A. Create an Amazon CloudWatch alarm that enters the ALARM state when the CPUUtilization metric is less than 20%. Create an AWS Lambda function that the CloudWatch alarm invokes to terminate one of the EC2 instances in the ALB target group.
B. Create an EC2 Auto Scaling. Select the exisiting ALB as the load balancer and the existing target group as the target group. Set a target tracking scaling policy that is based on the ASGAverageCPUUtilization metric. Set the minimum instances to 2, the desired capacity to 3, the desired capacity to 3, the maximum instances to 6, and the target value to 50%. And the EC2 instances to the Auto Scaling group.
C. Create an EC2 Auto Scaling. Select the exisiting ALB as the load balancer and the existing target group. Set the minimum instances to 2, the desired capacity to 3, and the maximum instances to 6 Add the EC2 instances to the Scaling group.
D. Create two Amazon CloudWatch alarms. Configure the first CloudWatch alarm to enter the ALARM satet when the average CPUTUilization metric is below 20%. Configure the seconnd CloudWatch alarm to enter the ALARM state when the average CPUUtilization metric is aboove 50%. Configure the alarms to publish to an Amazon Simple Notification Service (Amazon SNS) topic to send an email message. After receiving the message, log in to decrease or increase the number of EC2 instances that are running
Answer: B
A company is migrating a Linux-based web server group to AWS. The web servers must access files in a shared file store for some content. The company must not make any changes to the application.

B. Configure an Amazon CloudFront distribution with an Amazon S3 bucket as the origin.
C. Create an Amazon Elastic File System (Amazon EFS) file system. Mount the EFS file system on all web servers.
D. Configure a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume. Mount the EBS volume to all web servers.
Answer: C

A company has an application that places hundreds of .csv files into an Amazon S3 bucket every hour. The files are 1 GB in size. Each time a file is uploaded, the company needs to convert the file to Apache Parquet format and place the output file into an S3 bucket.
Which solution will meet these requirements with the LEAST operational overhead?
A. Create an AWS Lambda function to download the .csv files, convert the files to Parquet format, and place the output files in an S3 bucket. Invoke the Lambda function for each S3 PUT event.
B. Create an Apache Spark job to read the .csv files, convert the files to Parquet format, and place the output files in an S3 bucket. Create an AWS Lambda function for each S3 PUT event to invoke the Spark job.
C. Create an AWS Glue table and an AWS Glue crawler for the S3 bucket where the application places the .csv files. Schedule an AWS Lambda function to periodically use Amazon Athena to query the AWS Glue table, convert the query results into Parquet format, and place the output files into an S3 bucket.
D. Create an AWS Glue extract, transform, and load (ETL) job to convert the .csv files to Parquet format and place the output files into an S3 bucket. Create an AWS Lambda function for each S3 PUT event to invoke the ETL job.
Answer: D
