A SysOps administrator must ensure that a company's Amazon EC2 instances auto scale as expected. The SysOps administrator configures an Amazon EC2 Auto Scaling lifecycle hook to send an event to Amazo

Question

Options

• AAdd a permission to the Lambda function so that it can be invoked by the EventBridge
• BChange the lifecycle hook action to CONTINUE if the lifecycle hook experiences a fa* we or
• CConfigure a retry policy in the EventBridge (CloudWatch Events) rule to retry the Lambda function
• DUpdate the Lambda function execution role so that it has permission to call the complete lifecycle-

• A
  82% (32)
• B
  5% (2)
• C
  10% (4)
• D
  3% (1)

Explanation

To allow the EventBridge (CloudWatch Events) rule to invoke the Lambda function, the function's execution role needs to have the necessary permissions to be invoked by the rule. Specifically, the execution role needs to have an event pattern that matches the rule and an IAM policy that grants the necessary permissions to execute the Lambda function. By adding the necessary permissions to the Lambda function, the SysOps administrator can ensure that the function is invoked when the EC2 instances auto scale. Option D is incorrect because updating the Lambda function execution role so that it has permission to call the complete-lifecycle-action event will not address the issue of the Lambda function not being invoked by the EventBridge (CloudWatch Events) rule.
