C)DFE Passing Score 2026: Exactly What You Need to Pass

The Number: 70% on 100 Questions

The passing standard for the Certified Digital Forensics Examiner credential from Mile2 Cybersecurity Institute is a minimum score of 70%. The current six-page Mile2 course outline states the format plainly: 100 multiple-choice questions, approximately two hours, and a minimum 70% grade, delivered online through your candidate account on Mile2's learning management system.

That is the full extent of what is officially stated about scoring. There is no published scaled-score range, no stated curve, and no per-domain minimum. If you see a different number on a third-party site, treat it as unverified. This page sticks to what the sponsor's own materials say, and it flags the gaps rather than filling them with guesses.

What 70% Means in Practice

On a 100-question exam, 70% translates to 70 correct answers, but only if all 100 items count toward your score. Mile2 does not disclose whether the exam includes unscored questions, so the safest planning assumption is simply this: you need to be right on roughly seven out of ten items, and you should not count on knowing which ones are scored.

The practical takeaway: a 30-question cushion sounds comfortable, but this is a broad exam spanning seventeen course modules. Candidates tend to get hurt not by one hard topic but by a pile of small gaps in modules they skimmed. For a deeper look at how demanding that breadth feels, see How Hard Is the C)DFE Exam?.

What Mile2 Does Not Publish

Honest score-planning means knowing where the public record stops. Based on the current official outline and FAQ, the following are not verified:

• Domain weights. The seventeen course modules are published, but no official percentage allocation per module exists in the sources reviewed. The highest-weighted area is unknown.
• Scored versus unscored items. The split, if any, is undisclosed.
• Pass rate. No candidate pass rate is publicly disclosed. Our C)DFE pass rate analysis explains what can and cannot be said responsibly.
• Numbered exam version. No numbered 2026 exam revision is asserted by the outline, which carries a December 2, 2025 file date.
• Open-book, calculator and adaptive policies. Not officially verified, so do not assume any of them.

Exam Format and Logistics That Affect Your Score

Two hours, no pause

You have approximately two hours for 100 questions, which averages out to a little over a minute per item. There is no pause function, so settle your environment first: quiet space, snacks and water ready, notifications silenced. A forensics exam rewards careful reading of scenario wording, and rushing at the end is a common way to drop marginal points.

Online delivery through your Mile2 account

The exam is taken online through the candidate's account on Mile2's learning management system. Standard Mile2 exams generally do not require a live-proctor appointment, and the Certified Digital Forensics Examiner exam is not identified among the exceptions in the FAQ. The technical requirements are a current Chrome browser and a stable internet connection. Test both before you begin; a dropped connection mid-exam with no pause button is a risk you can avoid.

No separately scored practical

The course includes seventeen labs, but they support learning. There is no evidence of a separately scored practical examination for this certification. Your 70% is earned entirely on the multiple-choice exam, which means you must be able to explain forensic procedures in words, not just perform them in a tool.

Fees and access

Mile2's own Udemy description, updated January 2026, states USD 400 for the exam. The current direct U.S. checkout price was not exposed in the sources reviewed, so confirm it at purchase. Mile2's FAQ describes an Exam Combo that includes a guide, a practice simulator and two attempts; do not substitute reseller package prices when budgeting. Training is not mandatory, since the sponsor allows exam purchase without taking the course. Full cost context is in our C)DFE certification cost breakdown, and eligibility details are in C)DFE Requirements.

The 17-Module Scope You Are Scored Against

Because weights are unpublished, your best defense is coverage. The seventeen modules below come straight from the current Mile2 outline. For a fuller walkthrough of each, see C)DFE Exam Domains: Complete Guide to All 17 Content Areas.

Where Points Hide: High-Risk Topics

Since official weights are unavailable, the following is editorial judgment, not a published blueprint. These areas combine concept-heavy vocabulary with scenario-style questions, which makes them common places to lose points on a 70% line.

Evidence integrity and admissibility

Modules 5, 6 and 17 overlap here. Expect to distinguish authentication from admissibility, understand why the best evidence rule and hearsay matter to digital material, and recognize how alteration threatens authenticity. These are conceptual questions; memorizing definitions without understanding the reasoning is risky.

The investigative process in order

Module 4 lays out a sequence: identification and scope, collection and preservation, examination, analysis and interpretation, documentation and interim reporting, then quality control and review. Questions often test whether you know what belongs at which stage and what should never be skipped. Know the order cold.

Live versus dead acquisition decisions

Module 8 asks you to think across Windows, macOS, Linux/UNIX and cloud or virtualized environments. The reasoning behind capturing volatile data, and the tradeoffs of touching a running system, is more valuable than tool trivia. Module 6's field triage model (CFFTPM) pairs naturally with this.

Artifact locations and log reading

Modules 9-12 reward candidates who know where evidence lives: Windows event logs in EVT and EVTX formats, common Linux log files, OSX default apps and artifacts, web and memory artifacts. Module 13 adds regular expressions and file signature analysis, including headers and hex, which are easy to overlook if you study only by reading.

Scheduling Modules Around the 70% Line

One generic rule applies here: front-load concepts that later modules depend on. Below is a sample eight-week order tied to how the modules build on each other. Adjust the pace to your background, and see the C)DFE Study Guide for a fuller plan.

Treating your own practice scores as a signal is sensible: if you are consistently landing below 70% on timed, mixed-module sets, you are not yet at the exam's passing line. Consider that a reason to review, not a verdict. For a compact refresher in the final days, the C)DFE cheat sheet is useful.

Attempts, Vouchers and Renewal

Voucher and retake mechanics

An exam voucher is valid for one year, so schedule your study window to finish well inside it. If you buy Mile2's Exam Combo, the FAQ describes two attempts as part of the package; confirm the current terms at checkout rather than relying on reseller listings. Timing and scheduling details are covered in C)DFE Exam Dates.

What passing earns, and how long it lasts

The certification is valid for three years. Renewal sources are worded differently, so check the current policy before relying on any one summary:

The published renewal fee is USD 200 for the U.S. region, and potentially USD 100 for eligible developing regions. The optional five-day course earns 40 CEUs, but those describe training, and 40 course CEUs alone should not be assumed to renew the credential. If you are weighing whether the credential justifies this ongoing commitment, read Is the C)DFE Certification Worth It?, and for the career side, C)DFE Jobs and the C)DFE salary guide.
