How demanding this exam is

Cognitive load
Extremely high. CISSP requires broad recall and application of controls across eight domains, made harder by adaptive questioning. Candidates must evaluate long scenario-based questions, choose between multiple technically plausible answers, and maintain stamina for up to 180 minutes. Passing requires balanced mastery of governance, architecture, network security, IAM, testing, operations, and software security.
