    In the Timed Mode test there is a question:

    A startup created an AI-based traffic monitoring service. You need to register a new domain called http://www.tutorialsdojo-ai.com and set up other DNS entries for the other components of the system in AWS. Which of the following is not supported by Amazon Route 53?

    With the possible answers:

    1. PTR (pointer record)
    2. DNSSEC (Domain Name System Security Extensions)
    3. SPF (sender policy framework)
    4. SRV (service locator)

    <div>

    The correct answer is stated to be DNSSEC, with the note “Take note that DNSSEC is not a valid DNS record type. It is just a set of protocols that add a layer of security to the domain name system (DNS) lookup.”

    However the question does not ask which DNS record types are not supported by Amazon Route 53. It asks what is not supported by Route 53. https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/domain-configure-dnssec.html clearly states that Route 53 supports DNSSEC.

    </div>

    Hello Sam,

    Thanks for your feedback.

    The DNSSEC support in Route 53 is quite new and was announced last Dec 17, 2020. Take note that it would take around 6 months before new services/topics are incorporated into the AWS exam. No one really knows the exact date except for the AWS team, so the change could be reflected earlier. We will update our question once we’ve confirmed that AWS has also updated theirs.

    Let me know if you have any queries.

    Regards,

    Carlo @ Tutorials Dojo

    Oh, I didn’t realise DNSSEC support is new. That makes sense. Thanks for the explanation. Feel free to close this out.
