                                                                                                                                                                                                                        What score passes the CS0-004 exam, and what is the fee?

                                                                                                                                                                                                                        Passing the CompTIA Cybersecurity Analyst (CySA+) Certification exam requires 750 (on a scale of 100-900), and the registration fee is USD 404. Since retakes are not free, a readiness check with the VCETorrent practice engines is a sensible step before you commit to an exam date.
