The phrase "elastic" refers to the ability of a user to construct, launch, and terminate server instances as needed while paying per second for active servers.
By giving users control over the physical location of instances, EC2 enables users to reduce latency and increase redundancy. the capacity to acquire resources as needed and to release resources as required. You want to carry out this task automatically in the cloud. Even if an instance becomes ill or based on criteria you specify, Amazon EC2 Auto Scaling will automatically adjust the number of instances in the group to maintain a fixed number of instances.

Answer:
Challenge-Handshake Authentication Protocol (CHAP).
Explanation:
In Computer technology, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.
In this scenario, an organization wants to implement a remote dial-in server to ensure that personnel can connect to the organization's network from remote locations. The authentication protocol must include encryption to prevent hackers from accessing the network.
Hence, the protocol which should be used is Challenge-Handshake Authentication Protocol (CHAP).
A Challenge-Handshake Authentication Protocol (CHAP) can be defined as a standard network access control protocol in which a client program dials in to a network access server to receive a random value and identification number that can only be used once.
