Amazon Amazon Certifications SAP-C01 Questions & Answers

• Question 621:

  How can you check the operational validity of your AWS CloudFormation template?

  A. To check the operational validity, you need to attempt to create the stack.

  B. There is no way to check the operational validity of your AWS CloudFormation template.

  C. To check the operational validity, you need a sandbox or test area for AWS CloudFormation stacks.

  D. To check the operational validity, you need to use the aws cloudformation validate-template command.

  Correct Answer: A

  In AWS CloudFormation, to check the operational validity, you need to attempt to create the stack. There is no sandbox or test area for AWS CloudFormation stacks, so you are charged for the resources you create during testing.

• Question 622:

  True or false: In CloudFormation, you cannot create an Amazon RDS DB instance from a snapshot.

  A. False, you can specify it in attributes

  B. False, you can specify it in condition

  C. False, you can specify it in resource properties

  D. True

  Correct Answer: C

  In AWS CloudFormation, resource properties are additional options that you can specify on a resource. For example, you can specify the DB snapshot property for an Amazon RDS DB instance in order to create a DB instance from a snapshot.

• Question 623:

  True or false: In a CloudFormation template, you can reuse the same logical ID several times to reference the resources in other parts of the template.

  A. True, a logical ID can be used several times to reference the resources in other parts of the template.

  B. False, a logical ID must be unique within the template.

  C. False, you can mention a resource only once and you cannot reference it in other parts of a template.

  D. False, you cannot reference other parts of the template.

  Correct Answer: B

  In AWS CloudFormation, the logical ID must be alphanumeric (A-Za-z0-9) and unique within the template. You use the logical name to reference the resource in other parts of the template.

• Question 624:

  For Amazon EC2 issues, while troubleshooting AWS CloudFormation, you need to view the cloud-init and cfn logs for more information. Identify a directory to which these logs are published.

  A. /var/opt/log/ec2

  B. /var/log/lastlog

  C. /var/log/

  D. /var/log/ec2

  Correct Answer: C

  When you use AWS CloudFormation, you might encounter issues when you create, update, or delete AWS CloudFormation stacks. For Amazon EC2 issues, view the cloud-init and cfn logs. These logs are published on the Amazon EC2 instance in the /var/log/ directory. These logs capture processes and command outputs while AWS CloudFormation is setting up your instance. For Windows, view the EC2Configure service and cfn logs in %ProgramFiles%\Amazon\EC2ConfigService and C:\cfn\log. You can also configure your AWS CloudFormation template so that the logs are published to Amazon CloudWatch, which displays logs in the AWS Management Console so you don't have to connect to your Amazon EC2 instance.

• Question 625:

  AWS CloudFormation ______ are special actions you use in your template to assign values to properties that are not available until runtime.

  A. intrinsic functions

  B. properties declarations

  C. output functions

  D. conditions declarations

  Correct Answer: A

  AWS CloudFormation intrinsic functions are special actions you use in your template to assign values to properties not available until runtime. Each function is declared with a name enclosed in quotation marks (""), a single colon, and its parameters.

• Question 626:

  AWS ________supports__________ environments as one of the AWS resource types.

  A. Elastic Beanstalk; Elastic Beanstalk application

  B. CloudFormation; Elastic Beanstalk application

  C. Elastic Beanstalk ; CloudFormation application

  D. CloudFormation; CloudFormation application

  Correct Answer: B

  AWS CloudFormation and AWS Elastic Beanstalk services are designed to complement each other. AWS CloudFormation supports Elastic Beanstalk application environments as one of the AWS resource types.

• Question 627:

  A user is using CloudFormation to launch an EC2 instance and then configure an application after the instance is launched. The user wants the stack creation of ELB and AutoScaling to wait until the EC2 instance is launched and configured properly.

  How can the user configure this?

  A. The user can use the DependentCondition resource to hold the creation of the other dependent resources.

  B. It is not possible that the stack creation will wait until one service is created and launched.

  C. The user can use the HoldCondition resource to wait for the creation of the other dependent resources.

  D. The user can use the WaitCondition resource to hold the creation of the other dependent resources.

  Correct Answer: D

  AWS CloudFormation is an application management tool that provides application modeling, deployment, configuration, management, and related activities. AWS CloudFormation provides a WaitCondition resource that acts as a barrier and blocks the creation of other resources until a completion signal is received from an external source, such as a user application or management system.

• Question 628:

  When using the AWS CLI for AWS CloudFormation, which of the following commands returns a description of the specified resource in the specified stack?

  A. describe-stack-events

  B. describe-stack-resource

  C. create-stack-resource

  D. describe-stack-returns

  Correct Answer: B

  awsclicloudformation describe-stack-resource Description Returns a description of the specified resource in the specified stack. For deleted stacks, describe-stackresource returns resource information for up to 90 days after the stack has been deleted.

  Reference: http://docs.aws.amazon.com/cli/latest/reference/cloudformation/describe-stack-resource.html

• Question 629:

  In the context of AWS CloudFormation, which of the following statements is correct?

  A. Actual resource names are a combination of the resource ID, stack, and logical resource name.

  B. Actual resource name is the stack resource name.

  C. Actual resource name is the logical resource name.

  D. Actual resource names are a combination of the stack and logical resource name.

  Correct Answer: D

  In AWS CloudFormation, actual resource names are a combination of the stack and logical resource name. This allows multiple stacks to be created from a template without fear of name collisions between AWS resources.

• Question 630:

  For AWS CloudFormation, which stack state refuses UpdateStack calls?

  A. UPDATE_ROLLBACK_FAILED

  B. UPDATE_ROLLBACK_COMPLETE

  C. UPDATE_COMPLETE

  D. CREATE_COMPLETE

  Correct Answer: A

  When a stack is in the UPDATE_ROLLBACK_FAILED state, you can continue rolling it back to return it to a working state (to UPDATE_ROLLBACK_COMPLETE). You cannot update a stack that is in the UPDATE_ROLLBACK_FAILED state. However, if you can continue to roll it back, you can return the stack to its original settings and try to update it again.
