Question : A user is having data generated randomly based on a certain event. The user wants to upload that data to CloudWatch. It may happen that event may not have data generated for some period due to randomness. Which of the below mentioned options is a recommended option for this case? 1. For the period when there is no data, the user should not send the data at all 2. For the period when there is no data the user should send a blank value 3.

Explanation: AWS CloudWatch supports the custom metrics. The user can always capture the custom data and upload the data to CloudWatch using CLI or APIs. When the user data is more random and not generated at regular intervals, there can be a period which has no associated data. The user can either publish the zero 0. Value for that period or not publish the data at all. It is recommended that the user should publish zero instead of no value to monitor the health of the application. This is helpful in an alarm as well as in the generation of the sample data count.
Question : A user is sending the data to CloudWatch using the CloudWatch API. The user is sending data minutes in the future. What will CloudWatch do in this case?
With Amazon CloudWatch, each metric data point must be marked with a time stamp. The user can send the data using CLI but the time has to be in the UTC format. If the user does not provide the time, CloudWatch will take the data received time in the UTC timezone. The time stamp sent by the user can be up to two weeks in the past and up to two hours into the future.
Question : A user wants to upload a complete folder to AWS S using the S Management console. How can the user perform this activity?

Explanation: AWS S3 provides a console to upload objects to a bucket. The user can use the file upload screen to upload the whole folder in one go by clicking on the Enable Enhanced Uploader option. When the user uploads afolder, Amazon S3 uploads all the files and subfolders from the specified folder to the user's bucket. It then assigns a key value that is a combination of the uploaded file name and the folder name.
