An administrator needs to securely access a VM on an IaaS platform using an automated method, allowing administrators full access, denying others, and granting read-only to everyone else. Which technology should be used?

• A. JQuery
• B. JavaScript
• C. Java
• D. JSON

Answer: (C)

Automated secure access to an IaaS VM requires a programmable approach that can authenticate to the cloud API, manage sessions securely, and enforce access controls via the platform’s IAM policies. A programming language with robust cloud SDKs and enterprise-grade security features fits this need best. Java provides mature libraries and tooling for interacting with cloud APIs, supports secure credential management and TLS, and can run as a background automation service or within a server application. With Java, you can build a script or service that authenticates (using service accounts, OAuth, or API keys), calls the IaaS API to manage VMs, and apply IAM-based permissions so administrators have full access, others are denied, and read-only access is granted to everyone else. The other options aren’t suitable for this scenario: JQuery and JavaScript are client-side technologies meant for browsers and aren’t designed for secure, scalable server-side automation with cloud API access; JSON is just a data interchange format and doesn’t provide any capability to perform actions or enforce access control.
