A user is trying to setup a scheduled scaling activity using Auto Scaling. The user wants to setup the recurring schedule. Which of the below mentioned parameters is not required in this case?
Suggested Answer:A🗳️
When you update a stack with an Auto Scaling group and scheduled action, AWS CloudFormation always sets the min size, max size, and desired capacity properties of your Auto Scaling group to the values that are defined in the AWS::AutoScaling::AutoScalingGroup resource of your template, even if a scheduled action is in effect. Auto Scaling based on a schedule allows the user to scale the application in response to predictable load changes. The user can also configure the recurring schedule action which will follow the Linux cron format. If the user is setting a recurring event, it is required that the user specifies the Recurrence value (in a cron format., end time (not compulsory but recurrence will stop after this. and the Auto Scaling group for which the scaling activity is to be scheduled. Reference: http://docs.aws.amazon.com/es_es/AWSCloudFormation/latest/UserGuide/aws-resource-as-scheduledaction.html
Must:
Name
Start Time
Only one of these values need to be adjusted to create an instance:
Desired Capacity
Min
Max
Recurrence is set as Once by default, however if you adjust to x times, you will can enter an end date along with the start date, but not required. But if end time is not specified, then the instances will remain
https://docs.aws.amazon.com/autoscaling/ec2/userguide/schedule_time.html
A is the answer
I have checked in the console and you can provide at least one value for Desired, Min, or Max Capacity
(B) ASG Name is mandatory
(C) End time is mandatory
(D) Recurrence is mandatory
Start Time [required/optional]: The time when the scaling action should occur.
End Time [required/optional]: The time when the scaling action should end. This value applies only when Recurrence is set as well. Otherwise it will be skipped.
Answer is C
C: There is NO mention of using either Cloudfront or a Cloudfront stack. Therefore you need to focus on the question which only refers to AutoScaling...
Ans A is right.
Specify the size of the group using at least one of the following values: Min, Max, or Desired Capacity.
