- Mile2 publishes 17 course modules as preparation scope, but no verified domain weights, so study everything.
- The exam is delivered online through your Mile2 account; the course labs are not a separately scored practical exam.
- Chain of custody, admissibility and documentation concepts thread through nearly every module, not just the legal ones.
What This Exam Actually Is (and Isn't)
The Certified Digital Forensics Examiner, styled C)DFE (and sometimes written CDFE), is issued by Mile2 Cybersecurity Institute. That identification matters because several credentials in the industry share similar acronyms, and their exam details differ. Everything in this guide refers only to the Mile2 credential and its published course outline. If you want a plain-language orientation first, see What Is C)DFE Certification? and What Does C)DFE Stand For?.
The most important thing to understand before you start studying is the shape of the evidence you have. Mile2 publishes a six-page course outline with 17 modules. It does not publish numerical domain weights, a scored versus unscored question split, or a pass rate. That means any study guide that tells you "Domain 9 is 18% of the exam" is inventing something. Your job is to treat the 17 modules as unweighted preparation categories and build breadth across all of them. For a deeper look at how those categories break down, read C)DFE Exam Domains 2026: Complete Guide to All 17 Content Areas.
Format, Fees and Delivery Mechanics
Here is what is confirmed about the exam itself, drawn from the current Mile2 outline and sponsor materials:
| Item | What Is Published |
|---|---|
| Question count and type | 100 multiple-choice questions |
| Time allowed | Approximately 2 hours, with no pause |
| Minimum passing score | 70% |
| Delivery | Online, through your candidate account on Mile2's learning management system |
| Browser/connection | Current Chrome and a stable internet connection |
| Exam fee | Mile2's sponsor-authored Udemy description (updated January 2026) states USD 400; confirm current checkout pricing directly |
| Voucher validity | One year |
| Practical component | No separately scored practical exam is established; course labs support learning |
A few details are deliberately not claimed here because they are not officially verified: whether the exam is open-book, whether a calculator is permitted, and whether the test is adaptive. Check the candidate instructions in your account before test day rather than assuming. For the numbers in more detail, see C)DFE Passing Score 2026: Exactly What You Need to Pass and C)DFE Certification Cost 2026: Complete Pricing Breakdown.
Who Can Sit the Exam
Mile2 suggests one year of computer experience and, as background, its C)SP course and Foundational Course Pack. Importantly, the sponsor allows you to purchase the exam without taking the training, and there is no mandatory degree, verified employment-hour threshold or reference requirement. The full picture is in C)DFE Requirements 2026: Eligibility, Prerequisites & How to Qualify.
If you are weighing the optional five-day course, note what it is: it earns 40 CEUs and covers the 17 modules with labs. The five days and the 40 CEUs describe the training, not the exam duration or weighting. More on that route at C)DFE Training.
The 17-Module Scope Map
The 17 modules are the backbone of your preparation. They fall naturally into five clusters, and organizing your notes this way makes the sheer volume manageable:
- Foundations and law (Modules 1 to 3, 5): incidents, theory, prerequisites and standards, evidence protocols.
- Process and acquisition (Modules 4, 6, 7, 8): the investigative process, tools, storage, live acquisition.
- Operating-system artifacts (Modules 9 to 11): Windows, Linux, macOS.
- Specialized analysis (Modules 12 to 15): artifact recovery, search strings and signatures, mobile, eDiscovery.
- Operations and courtroom (Modules 16, 17): lab protocols, presentation and reporting.
Foundations: Incidents, Theory, Process and Law
Domain 1: Computer Forensics Incidents
This module opens with the origins of digital forensic science, the legal system, types of cybercrime incidents, and internal versus external threats.
- Be able to distinguish insider-driven incidents from external intrusions and how that shapes an investigation.
- Know the basic categories of cybercrime incidents an examiner is likely to be asked to investigate.
Domain 2: Computer Forensic Investigative Theory
Covers investigative theory and concepts, plus behavioral evidence analysis (BEA) and equivocal forensic analysis (EFA).
- Learn what "equivocal" analysis means: evidence that supports more than one explanation must be examined before conclusions are drawn.
- Expect conceptual questions here rather than tool syntax.
Domain 3: Computer Forensic Prerequisites and Standards
Investigative prerequisites, scene management and industry standards. Mile2's materials reference NIST 800-101 and ISO/IEC 27037 as training context, so be familiar with what these documents address in general terms (mobile device forensics guidance and digital evidence handling respectively) without memorizing revision numbers.
Domain 4: Computer Forensic Investigative Process
This is arguably the conceptual spine of the whole course. The published subtopics run in sequence:
- Foundations of the digital forensics process
- Identification and scope
- Collection and preservation
- Examination
- Analysis and interpretation
- Documentation and interim reporting
- Quality control and review
Memorize the order and what belongs in each phase. Scenario questions often hinge on recognizing which phase a described action falls into, or what should have happened earlier.
Domain 5: Forensic Examination/Evidence Protocols
Science applied to forensics, digital evidence categories and evidence admissibility. This module connects the technical work to legal acceptability, a theme that returns in Module 17.
Acquisition, Tools and Storage
Domain 6: Digital Acquisition and Analysis Tools
Acquisition procedures, the computer forensics field triage process model (CFFTPM), evidence authentication, forensic tools, and AI and forensics.
- Understand why triage exists: when full imaging is impractical, a structured field process prioritizes what to collect.
- Evidence authentication is about proving that what you analyzed matches what you collected.
- Commercial tools appear as training context. Focus on what categories of tools do rather than on feature lists, which change.
Domain 7: Disks and Storages
Disk operating systems and filesystems, spinning-disk forensics, SSD forensics (with an IoT mention), cloud storage, and handling damaged drives.
- Know how spinning disks and SSDs differ in how deleted data behaves and why that affects recovery expectations.
- Cloud storage raises jurisdiction and access questions that physical media does not.
Domain 8: Live Acquisitions
General live acquisition, then Windows, macOS, Linux/UNIX, and cloud/virtualization acquisition.
- Study the trade-off at the heart of live collection: volatile data is valuable but collecting it alters the system.
- Be ready to reason about order of volatility and what you document when you must touch a running machine.
Windows, Linux and macOS Artifacts
Domain 9: Windows Forensics
The published scope is the Windows Event Viewer overview, EVTX and EVT logs, and log analysis to identify breaches and attacks.
- Know the difference between the legacy EVT format and the newer EVTX format.
- Practice reading log entries to reconstruct what happened, not just recognizing event categories.
Domain 10: Linux Forensics
Linux artifacts: file system structure, basic identifiers and common log files. Know where an examiner looks on a Linux host and what the standard logs record.
Domain 11: MAC Forensics
OSX artifacts: file system structure, default apps and other artifacts. Treat this as the third leg of a stool with Windows and Linux. Candidates who work only in Windows environments tend to underestimate it.
A practical approach is to build a three-column comparison for yourself: for each operating system, note the file system, the primary log or artifact locations, and the acquisition considerations from Module 8. The act of building it forces the cross-domain connections the exam rewards.
Specialized Recovery, Search Strings, Mobile and eDiscovery
Domain 12: Specialized Artifact Recovery
Windows components with investigative interest, files containing historical information, web forensics and memory forensics. These topics reward breadth: know what each artifact type can reveal about user activity over time.
Domain 13: Advanced Search Strings and File Signatures
Search strings, regular expressions (REGEX), and file signatures covering formats, headers and hex analysis.
- Practice reading and writing basic regular expressions; this is a skill best learned by doing.
- Learn how file headers identify true file type regardless of extension, and why that matters when someone renames a file.
Domain 14: Mobile Forensics
The forensic process for mobile devices, tools, IoT and wearables, and legal considerations. Note the explicit inclusion of IoT and wearables; do not skip them.
Domain 15: eDiscovery
eDiscovery, laws and regulations, and the eDiscovery process. This is where forensics meets civil litigation, and the vocabulary differs from criminal investigation work. Learn the process stages and why defensible handling matters.
Lab Protocols and Evidence Presentation
Domain 16: Computer Forensic Laboratory Protocols
Forensic workstation preparation, lab standard operating procedures, quality assurance, quality control, peer review, annual review, deviations and lab intake.
- Distinguish quality assurance (preventing problems through process) from quality control (checking results).
- Understand what a documented deviation from procedure is and why it must be recorded, not hidden.
Many technically strong candidates lose points here because lab management feels less glamorous than imaging a drive. Do not neglect it.
Domain 17: Digital Evidence Presentation and Reporting
The best evidence rule, hearsay, authenticity and alteration, and report sections and content.
- Be able to explain why a copy or printout of digital data can still qualify as original evidence under the best evidence concept.
- Know the elements a complete forensic report contains and why each exists.
Key Takeaway
Integrity, documentation and admissibility are the connective tissue of the whole outline. When a scenario question seems ambiguous, ask which answer best preserves evidence integrity and creates a defensible record.
A Domain-Ordered Study Sequence
Because there are no published weights, an even-coverage plan beats a guess-the-heavy-domain plan. The sequence below follows the logical dependency between modules: process and law first, because they give meaning to everything after. It is a template; stretch or compress it to your calendar. For a quick review artifact once you finish, see the C)DFE Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Foundations and Process (Modules 1 to 5)
- Memorize the seven phases of the investigative process in order.
- Build a short glossary of admissibility and evidence-category terms.
Acquisition and Storage (Modules 6 to 8)
- Compare spinning disk and SSD behavior for deleted data.
- Write out the live-acquisition trade-offs for each operating system.
OS Artifacts (Modules 9 to 11)
- Build the three-OS comparison table described above.
- Read sample event log entries and narrate what happened.
Specialized Analysis (Modules 12 to 15)
- Practice basic REGEX and header identification by hand.
- Outline the eDiscovery process and mobile forensic process side by side.
Lab, Reporting and Full Review (Modules 16, 17)
- Study QA versus QC and the report structure.
- Take timed practice sets across all 17 modules and revisit weak areas.
When you are ready to test yourself under realistic conditions, use the C)DFE practice tests and aim for timed, full-length runs. If you want to calibrate expectations before committing, How Hard Is the C)DFE Exam? Complete Difficulty Guide 2026 and C)DFE Pass Rate 2026: What the Data Shows are worth reading. Note that Mile2 does not publicly disclose a candidate pass rate, so treat any specific figure you see elsewhere with skepticism.
Exam-Day Realities for an Online, Two-Hour Test
The pacing math is simple: 100 questions in roughly 120 minutes is a little over a minute per question. Since the time cannot be paused, do the following:
- Prepare your environment in advance. A current Chrome browser and a stable connection are required. Test both before you start the clock.
- Do not assume extras. Open-book, calculator and adaptive policies are not officially verified, so read your candidate instructions rather than relying on rumor.
- Work the scenario questions by phase. Identify which investigative phase or module the question belongs to, then eliminate answers that violate preservation or documentation principles.
- Flag and move. A single hard question about a niche artifact should not consume five minutes you need elsewhere.
- Know your scheduling constraints. The exam is delivered online through your account, and standard exams generally do not require a live-proctor appointment. See C)DFE Exam Dates 2026: Testing Windows, Deadlines & Scheduling for the scheduling picture, and remember your voucher is valid for one year.
Mile2's Exam Combo is described as including a guide, practice simulator and two attempts. If you are considering that package, confirm the current contents and price with Mile2 directly rather than relying on reseller listings.
After You Pass: Renewal and Career Context
Certification validity is three years. The renewal picture has two differently worded sources, and you should check current policy before relying on either:
- The course PDF lists a three-year expiration with two requirements: passing the current exam and submitting 20 CEUs per year.
- The separate current renewal-policy route describes 60 documented CEUs over the cycle, an ethics and policies acknowledgment and a fee, or a qualifying examination-based route. The published renewal fee is USD 200 for the U.S. region, potentially USD 100 for eligible developing regions.
Do not assume the 40 CEUs earned from the five-day course alone renew the credential. Verify the current requirements when you approach your renewal window.
On the career side, the certification maps to roles in incident response, corporate investigations, eDiscovery support and lab-based forensic work, given its emphasis on process, lab protocols and reporting. For realistic expectations about compensation and value, see C)DFE Salary Guide 2026: Complete Earnings Analysis, Is the C)DFE Certification Worth It? Complete ROI Analysis 2026 and C)DFE Jobs.

Frequently Asked Questions
The exam has 100 multiple-choice questions and approximately two hours, with no pause. You need a minimum of 70% to pass. The split between scored and unscored questions is not disclosed.
No. Mile2 publishes a 17-module course outline, but it does not publish numerical exam weights, so those modules should be treated as unweighted preparation categories. Study all of them rather than betting on a presumed heavy domain.
A separately scored practical exam is not established. The course includes labs that support learning, but the credential exam itself is the 100-question multiple-choice test delivered online through your Mile2 account.
No. Mile2 suggests one year of computer experience and its C)SP course and Foundational Course Pack as background, but it allows the exam to be purchased without the training. There is no mandatory degree or verified experience-hour threshold.
The certification is valid for three years. Renewal routes described by Mile2 involve documented CEUs, an ethics acknowledgment and a fee, or a qualifying examination-based option, and the course PDF words the requirements slightly differently. Confirm current renewal policy with Mile2 before your cycle ends.
