AWS-SysOps Free Practice Test

- (Exam Topic 1)
A SysOps administrator creates an AWS CloudFormation template to define an application stack that can be deployed in multiple AWS Regions.
The SysOps administrator also creates an Amazon CloudWatch dashboard by using the AWS Management Console. Each deployment of the application requires its own CloudWatch dashboard.
How can the SysOps administrator automate the creation of the CloudWatch dashboard each time the application is deployed?

1. A. Create a script by using the AWS CLI to run the aws cloudformation put-dashboard command with the name of the dashboar
2. B. Run the command each time a new CloudFormation stack is created.
3. C. Export the existing CloudWatch dashboard as JSO
4. D. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resourc
5. E. Include the exported JSON in the resource's DashboardBody property.
6. F. Update the CloudFormation template to define an resourc
7. G. Use the intrinsic Ref function to reference the ID of the existing CloudWatch dashboard.
8. H. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resourc
9. I. Specify the name of the existingdashboard in the DashboardName property.

Correct Answer: B
You can only use the Intrinsic Ref function to reference a resource that is being created at the same time as the current CloudFormation template. The question states that the CloudWatch dashboard was previously created using the AWS Management Console, so there is no ID to reference the existing CloudWatch dashboard in the CloudFormation template. You would need to export the existing CloudWatch dashboard as JSON, then use the DashboardBody property in the CloudFormation template to replicate it upon each deployment

A company has a stateless application that runs on four Amazon EC2 instances. The application requires tour instances at all times to support all traffic. A SysOps administrator must design a highly available,
fault-tolerant architecture that continually supports all traffic if one Availability Zone becomes unavailable.
Which configuration meets these requirements?

1. A. Deploy two Auto Scaling groups in two Availability Zones with a minimum capacity of two instances in each group.
2. B. Deploy an Auto Scaling group across two Availability Zones with a minimum capacity of four instances.
3. C. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of four instances.
4. D. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of six instances.

Correct Answer: C

A company has created a NAT gateway in a public subnet in a VPC. The VPC also contains a private subnet that includes Amazon EC2 instances. The EC2 instances use the NAT gateway to access the internet to download patches and updates. The company has configured a VPC flow log for the elastic network interface of the NAT gateway. The company is publishing the output to Amazon CloudWatch Logs.
A SysOps administrator must identify the top five internet destinations that the EC2 instances in the private subnet communicate with for downloads.
What should the SysOps administrator do to meet this requirement in the MOST operationally efficient way?

1. A. Use AWS CloudTrail Insights events to identify the top five internet destinations.
2. B. Use Amazon CloudFront standard logs (access logs) to identify the top five internet destinations.
3. C. Use CloudWatch Logs Insights to identify the top five internet destinations.
4. D. Change the flow log to publish logs to Amazon S3. Use Amazon Athena to query the log files in Amazon S3.

Correct Answer: C

A SysOps administrator has successfully deployed a VPC with an AWS Cloud Formation template The SysOps administrator wants to deploy me same template across multiple accounts that are managed through AWS Organizations.
Which solution will meet this requirement with the LEAST operational overhead?

1. A. Assume the OrganizationAccountAcccssKolc IAM role from the management accoun
2. B. Deploy the template in each of the accounts
3. C. Create an AWS Lambda function to assume a role in each account Deploy the template by using the AWS CloudFormation CreateStack API call
4. D. Create an AWS Lambda function to query fc a list of accounts Deploy the template by using the AWS Cloudformation CreateStack API call.
5. E. Use AWS CloudFormation StackSets from the management account to deploy the template in each of the accounts

Correct Answer: D
AWS CloudFormation StackSets extends the capability of stacks by enabling you to create, update, or delete stacks across multiple accounts and AWS Regions

A company has a public website that recently experienced problems. Some links led to missing webpages, and other links rendered incorrect webpages. The application infrastructure was running properly, and all the provisioned resources were healthy. Application logs and dashboards did not show any errors, and no monitoring alarms were raised. Systems administrators were not aware of any problems until end users reported the issues.
The company needs to proactively monitor the website for such issues in the future and must implement a solution as soon as possible.
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Rewrite the application to surface a custom error to the application log when issues occur.Automatically parse logs for error
2. B. Create an Amazon CloudWatch alarm to provide alerts when issues are detected.
3. C. Create an AWS Lambda function to test the websit
4. D. Configure the Lambda function to emit an Amazon CloudWatch custom metric when errors are detecte
5. E. Configure a CloudWatch alarm to provide alerts when issues are detected.
6. F. Create an Amazon CloudWatch Synthetics canar
7. G. Use the CloudWatch Synthetics Recorder plugin to generate the script for the canary ru
8. H. Configure the canary in line with requirement
9. I. Create an alarm to provide alerts when issues are detected.

Correct Answer: A
