An edge location refers to which Amazon Web Service?
Correct Answer:C
Amazon CIoudFront is a content distribution network. A content delivery network or content distribution network (CDN) is a large distributed system of sewers deployed in multiple data centers across the world. The location of the data center used for CDN is called edge location.
Amazon CIoudFront can cache static content at each edge location. This means that your popular static content (e.g., your site’s logo, navigational images, cascading style sheets, JavaScript code, etc.) will be available at a nearby edge location for the browsers to download with low latency and improved performance for viewers. Caching popular static content with Amazon CIoudFront also helps you offload requests for such files from your origin sever — CIoudFront serves the cached copy when available and only makes a request to your origin server if the edge location receMng the browser’s request does not have a copy of the file.

A user has launched an EC2 instance. The instance got terminated as soon as it was launched. Which of the below mentioned options is not a possible reason for this?
Correct Answer:D
When the user account has reached the maximum number of EC2 instances, it will not be allowed to launch an instance. AWS will throw an ‘Instance Limit Exceeded’ error. For all other reasons, such as
"AMI is missing part", "Corrupt Snapshot" or "VoIume limit has reached" it will launch an EC2 instance and then terminate it.
