NSE requires an External Certification Authority.

NSE requires an External Certification Authority.

• A. TRUE
• B. FALSE
• C. NA
• D. NA

Answer: (A)

When NSE is secured with TLS, the system presents a certificate to prove its identity and encrypt communications. For clients to trust that certificate, it must chain back to a trusted root. An External Certification Authority provides widely trusted roots, so using a certificate issued by such an authority lets clients and other systems validate the identity without manual trust configuration. That’s why NSE typically requires an External Certification Authority: it ensures proper trust, interoperability, and certificate lifecycle management in production environments. In practice, you could use a self-signed or internal CA in isolated tests, but for standard deployment the external CA approach is the norm.
