Which method should a cloud administrator use to secure access to a VM while allowing administrative control?

1. jQuery

2. JavaScript

3. Java

4. JSON

The correct answer is: Java

The selection of Java as the method to secure access to a virtual machine (VM) while allowing administrative control relates to Java's capabilities in creating robust applications that can implement security protocols effectively. Java provides a rich set of libraries and frameworks conducive to building secure applications. It supports concepts such as secure sockets (SSL/TLS), which can encrypt the communication between the administrator and the VM, ensuring that sensitive information is transmitted securely. In contrast, the other options do not directly contribute to securing access in the way a dedicated programming language like Java can. jQuery and JavaScript are primarily used for client-side web development and may lack the robustness required for backend security implementations. JSON, while useful for data interchange and serialization, does not inherently provide any security features by itself since it is just a data format. Thus, utilizing Java allows for the implementation of comprehensive security measures for managing and accessing a VM, aligning well with the need for both security and administrative control.
