Question 1

A company runs a worker process on three Amazon EC2 instances. The instances are in an Auto Scaling group that is configured to use a simple scaling policy. The instances process messages from an Amazon Simple Queue Service (Amazon SQS) queue.

Random periods of increased messages are causing a decrease in the performance of the worker process. A SysOps administrator must scale the instances to accommodate the increased number of messages.

Which solution will meet these requirements?

A : Use CloudWatch to create a metric math expression to calculate the approximate age of the oldest message in the SQS queue. Create a target tracking scaling policy for the metric math expression to modify the Auto Scaling group.

B : Use CloudWatch to create a metric math expression to calculate the approximate number of messages visible in the SQS queue for each instance. Create a target tracking scaling policy for the metric math expression to modify the Auto Scaling group.

C : Create an Application Load Balancer (ALB). Attach the ALB to the Auto Scaling group. Create a target tracking scaling policy for the ALBRequestCountPerTarget metric to modify the Auto Scaling group.

D : Create an Application Load Balancer (ALB). Attach the ALB to the Auto Scaling group. Create a scheduled scaling policy for the Auto Scaling group.

Answer: B

Question 2

A company analyzes sales data for its customers. Customers upload files to one of the company's Amazon S3 buckets, and a message is posted to an Amazon

Simple Queue Service (Amazon SQS) queue that contains the object Amazon Resource Name (ARN). An application that runs on an Amazon EC2 instance polls the queue and processes the messages. The processing time depends on the size of the file.

Customers are reporting delays in the processing of their files. A SysOps administrator decides to configure Amazon EC2 Auto Scaling as the first step. The

SysOps administrator creates an Amazon Machine Image (AMI) that is based on the existing EC2 instance. The SysOps administrator also creates a launch template that references the AMI.

How should the SysOps administrator configure the Auto Scaling policy to improve the response time?

A : Add several different instance sizes in the launch template. Create an Auto Scaling policy based on the ApproximateNumberOfMessagesVisible metric to select the size of the instance based on the number of messages in the queue.

B : Create an Auto Scaling policy based on the ApproximateNumberOfMessagesDelayed metric to scale the number of instances based on the number of messages in the queue that have been delayed.

C : Create a custom metric based on the ASGAverageCPUUtilization metric and the GroupPendingInstances metric from the Auto Scaling group. Modify the application to calculate the metric and post the metric to Amazon CloudWatch once each minute. Create an Auto Scaling policy based on this metric to scale the number of instances.

D : Create a custom metric based on the ApproximateNumberOfMessagesVisible metric and the number of instances in the InService state in the Auto Scaling group. Modify the application to calculate the metric and post the metric to Amazon CloudWatch once each minute. Create an Auto Scaling policy based on this metric to scale the number of instances.

Answer: B

Question 3

A SysOps administrator applies the following policy to an AWS CloudFormation stack:

What is the result of this policy?

A : Users that assume an IAM role with a logical ID that begins with 'Production' are prevented from running the update-stack command.

B : Users can update all resources in the stack except for resources that have a logical ID that begins with 'Production'.

C : Users can update all resources in the stack except for resources that have an attribute that begins with 'Production'.

D : Users in an IAM group with a logical ID that begins with 'Production' are prevented from running the update-stack command.

Answer: B

Question 4

An errant process is known to use an entire processor and run at 100% A SysOps administrator wants to automate restarting the instance once the problem occurs for more than 2 minutes
How can this be accomplished?

A : Create an Amazon CloudWatch alarm for the Amazon EC2 instance with basic monitoring Enable an action to restart the instance

B : Create a CloudWatch alarm for the EC2 instance with detailed monitoring Enable an action to restart the instance

C : Create an AWS Lambda function to restart the EC2 instance triggered on a scheduled basis every 2 minutes

D : Create a Lambda function to restart the EC2 instance, triggered by EC2 health checks

Answer: B

Question 5

A company creates a new member account by using AWS Organizations. A SysOps administrator needs to add AWS Business Support to the new account

Which combination of steps must the SysOps administrator take to meet this requirement? (Select TWO.)

A : Sign in to the new account by using 1AM credentials. Change the support plan.

B : Sign in to the new account by using root user credentials. Change the support plan.

C : Use the AWS Support API to change the support plan.

D : Reset the password of the account root user.

E : Create an 1AM user that has administrator privileges in the new account.

Answer: B,D
