What term describes a collection of computing environments under a single authority with secure access controls?

• A. Enclave
• B. APC
• C. ECN
• D. ERS

Answer: (A)

An enclave is a secure boundary that groups multiple computing environments under one authority and enforces access controls across them. This setup ensures consistent authentication, authorization, and policy enforcement for everything inside the boundary, protecting resources and isolating them from outside domains. Because all systems within the enclave share a common security policy and control point, it’s easier to manage who can access what and to audit activity. The other terms describe things that aren’t a unified security domain of computing environments under central control, so they don’t fit the description as well.
