Question 36

A company is migrating its production file server to AWS. All data that is stored on the file server must remain accessible if an Availability Zone becomes unavailable or when system maintenance is performed. Users must be able to interact with the file server through the SMB protocol Users also must have the ability to manage file permissions by using Windows ACLs. Which solution will meet these requirements?

  1. Create a single AWS Storage Gateway file gateway.
  2. Create an Amazon FSx for Windows File Server Multi-AZ file system.
  3. Deploy two AWS Storage Gateway file gateways across two Availability Zones. Configure an Application Load Balancer in front of the file gateways.
  4. Deploy two Amazon FSx for Windows File Server Single-AZ 2 file systems Configure Microsoft Distributed File System Replication (DFSR).

Question 37

A company has a web application that is experiencing performance problems many times each night. A root cause analysis reveals sudden increases in CPU utilization that last 5 minutes on an Amazon EC2 Linux instance. A CloudOps engineer must find the process ID (PID) of the service or process that is consuming more CPU. What should the CloudOps engineer do to collect the process utilization information with the LEAST amount of effort?

  1. Configure the Amazon CloudWatch agent procstat plugin to capture CPU process metrics.
  2. Configure an AWS Lambda function to run every minute to capture the PID and send a notification.
  3. Log in to the EC2 instance by using a .pem key each night. Then run the top command.
  4. Use the default Amazon CloudWatch CPU utilization metric to capture the PID in CloudWatch.

Question 38

A company needs to monitor its website's availability to end users. The company needs a solution to provide an Amazon Simple Notification Service (Amazon SNS) notification if the website's uptime decreases to less than 99%. The monitoring must provide an accurate view of the user experience on the website. Which solution will meet these requirements?

  1. Create an Amazon CloudWatch alarm that is based on the website’s logs that are published to a CloudWatch Logs log group. Configure the alarm to publish an SNS notification if the number of HTTP 4xx errors and 5xx errors exceeds a specified threshold.
  2. Create an Amazon CloudWatch alarm that is based on the website's published metrics in CloudWatch. Configure the alarm to publish an SNS notification that is based on anomaly detection.
  3. Create an Amazon CloudWatch Synthetics heartbeat monitoring canary. Associate the canary with the website's URL for end users. Create a CloudWatch alarm for the canary. Configure the alarm to publish an SNS notification if the value of the SuccessPercent metric is less than 99%.
  4. Create an Amazon CloudWatch Synthetics broken link checker monitoring canary. Associate the canary with the website's URL for end users. Create a CloudWatch alarm for the canary. Configure the alarm to publish an SNS notification if the value of the SuccessPercent metric is less than 99%.

Question 39

A company uses Amazon EC2 Auto Scaling across multiple Availability Zones. The company must ensure that EC2 instances are provisioned in private subnets. The company recently optimized its cloud infrastructure by reducing the number of NAT gateways in the company’s VPC to one. Some EC2 instances lost internet connectivity after the infrastructure update. A CloudOps engineer must resolve the connectivity issue. Which solution will meet this requirement?

  1. Replace the existing NAT gateway with a NAT instance in the same subnet.
  2. Update VPC route tables to target the existing NAT gateway for internet traffic.
  3. Update VPC route tables to target an internet gateway for internet traffic.
  4. Add secondary IP addresses to the existing NAT gateway.

Question 40

A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A CloudOps engineer needs to keep the instances and all of the instances’ data, even if someone deletes the stack. Which solution will meet these requirements?

  1. Set the DeletionPolicy attribute to Snapshot for the EC2 instance resource in the CloudFormation template.
  2. Automate backups by using Amazon Data Lifecycle Manager (Amazon DLM).
  3. Create a backup plan in AWS Backup.
  4. Set the DeletionPolicy attribute to Retain for the EC2 instance resource in the CloudFormation template.
