Q

What is the connectivity option that uses Internet Protocol Security (IPSec) to establish encrypted connectivity between an on-premises network and the AWS Cloud?

A

AWS Site-to-Site VPN
-AWS Site-to-Site VPN utilizes Internet Protocol Security (IPSec) to establish encrypted connectivity between your on-premises network and AWS over the Internet. With AWS Client VPN, your users can access AWS or on-premises resources from any location using a secure TLS connection.
“AWS Direct Connect” is incorrect. AWS Direct Connect does not involve the Internet; instead, it uses dedicated, private network connections between your on-premises network or branch office site and the AWS Cloud. AWS Direct Connect is a network service that provides an alternative to using the Internet to connect customer’s on-premise sites to AWS. Using AWS Direct Connect, data that would have previously been transported over the Internet can now be delivered through a private network connection between AWS and your datacenter or corporate network.

Q

AWS recommends some practices to help organizations avoid unexpected charges on their bill. Which of the following is NOT one of these practices?

A

Deleting unused AutoScaling launch configuration

       "Deleting unused AutoScaling launch configuration" will not help, and thus is the correct choice. The AutoScaling launch configuration does not incur any charges. Thus, it will not make any difference whether it is deleted or not.
       AWS will charge the user once the AWS resource is allocated (even if it is not used). Thus, it is advised that once the user's work is completed they should: 1- Delete all Elastic Load Balancers. 2- Terminate all unused EC2 instances. 3- Delete the attached EBS volumes that they don’t need. 4- Release any unused Elastic IPs.
