• Question 194:

  An administrator tries to use the Amazon Machine Learning service to classify social media posts that mention the administrator's company into posts that require a response and posts that do not. The training dataset of 10,000 posts contains the details of each post including the timestamp, author, and full text of the post. The administrator is missing the target labels that are required for training.

  Which Amazon Machine Learning model is the most appropriate for the task?

  A. Binary classification model, where the target class is the require-response post
  B. Binary classification model, where the two classes are the require-response post and does-not-require-response
  C. Multi-class prediction model, with two classes: require-response post and does-not-require-response
  D. Regression model where the predicted value is the probability that the post requires a response
  A. Binary classification model, where the target class is the require-response post

• Question 195:

  Your application uses CloudFormation to orchestrate your application's resources. During your testing phase before application went live, your Amazon RDS instance type was changed and caused the instance to be re-created, resulting in the loss of test data.

  How should you prevent this from occurring in the future?

  A. Within the AWS CloudFormation parameter with which users can select the Amazon RDS instance type, set AllowedValues to only contain the current instance type
  B. Use an AWS CloudFormation stack policy to deny updates to the instance. Only allow UpdateStack permission to IAM principles that are denied SetStackPolicy
  C. In the AWS CloudFormation template, set the AWS::RDS::DBInstance's DBInstanceClass property to be read-only
  D. Subscribe to the AWS CloudFormation notification "BeforeResourceUpdate" and call CancelStackUpdate if the resource identified is the Amazon RDS instance
  E. In the AWS ClousFormation template, set the DeletionPolicy of the AWS::RDS::DBInstance's DeletionPolicy property to "Retain"
