Registration Authority — CISSP Practice Questions

A Registration Authority (RA) is a PKI component that acts as an intermediary between end entities requesting certificates and the Certificate Authority that issues them. The RA is responsible for verifying the identity and eligibility of certificate requestors before forwarding approved requests to the CA, offloading identity proofing workload from the CA itself. The CISSP exam tests whether candidates understand the separation of duties between the RA and CA, and why this separation is a security benefit. Misunderstanding the RA role is a common source of exam distractor confusion, particularly around what the RA can and cannot sign.
