Hello, I see "Active date" and "Expiration Date" column in the Exam scheudiling site - https://www.certmetrics.com/amazon/candidate/exam_scheduling.aspx . What are these dates for?
Hello @gmsaiful , Your AWS certification is only good for a specific time period, currently 2 years. So you would need to take the certification exam again prior to that expiration date to maintain your certification status.
The 2016 CDA Exam Retires on Nov. 19, if you wish to take that exam you have until the 19th to do so.
