ExploreAbout this exam
The CNDA is a cybersecurity certification offered by Mile2 Cybersecurity Institute, a training and certification body based in Tampa, Florida. The credential sits in Mile2's certification catalog alongside its other role-based and foundational programs, and its subject matter is network defense: the practices and controls used to protect networks, hosts, and boundaries against intrusion, and to detect and respond when defenses are tested. Candidates who pursue it are typically security analysts, network or systems administrators, SOC staff, and IT professionals moving into a defensive security role, as well as students in academic programs that use Mile2 materials. Mile2 markets its certifications to individuals and to organizations, and publishes a role-based certification roadmap, detailed course outlines, learning material samples, exam prep guides, and cyber range labs that candidates can use to plan study. Because the official CNDA page was unavailable when this profile was compiled, the exam's question count, time limit, passing score, price, delivery format, retake rules, and validity period are not confirmed here and should be verified directly with Mile2 before you register. Preparation generally means working through the vendor's course materials and outline, practicing hands-on defensive tasks in a lab environment, and reviewing exam requirements and technical requirements published by Mile2.
What you'll study
About CNDA preparation
Who issues the CNDA and where can I confirm it is still offered?
The CNDA is listed among the certifications of Mile2 Cybersecurity Institute. The dedicated CNDA page on Mile2's site returned a 404 when this profile was compiled, so confirm current availability, naming, and details directly with Mile2 or an authorized training partner before paying for study materials.
What does the exam cover?
The credential's subject is network defense: protecting network boundaries and endpoints, monitoring and analyzing activity to detect intrusions, and responding to incidents with layered defenses. Mile2 publishes detailed course outlines and learning material samples that describe the actual topic list; use those as the authoritative scope rather than third-party summaries.
How many questions are on the exam and how long do I have?
Not confirmed. The official CNDA page was not reachable when this profile was compiled, so question count, time limit, and passing score cannot be stated accurately. Check Mile2's certification page or ask a partner for the current exam blueprint before you schedule.
How much does the exam cost, and what does a retake cost?
Not confirmed. Mile2 sells exam-only combos, self-study bundles, and instructor-led classes through its shop, and pricing changes over time. Review the current product listing for the CNDA exam or combo, and read Mile2's policies and procedures page for retake and rescheduling terms.
What format is the exam delivered in?
Not confirmed from the source. Mile2 publishes a technical requirements document for exam delivery, which is the right place to check system, browser, and proctoring requirements. Read it well before your test date so a technical problem does not cost you an attempt.
How difficult is it, and what trips candidates up?
Difficulty is not published. The usual failure pattern on defense exams is memorizing tool names without understanding traffic, logs, and control placement. Practice reading packet captures and log output, and be able to explain why a given boundary or host control blocks a specific attack path, not just that it exists.
In what order should I study?
Start with the official course outline to map topics, then work through the vendor learning materials, then do hands-on labs. Mile2 offers cyber range access for practical work. Finish with the exam prep guide, and revisit weak areas rather than re-reading material you already know.
How long is the certification valid, and how do I renew it?
Not confirmed. Mile2 maintains a certification renewal program and sells renewal products, but the specific validity period for the CNDA was not stated on the available source. Check the certification renewal program page or contact Mile2 to learn your renewal obligations and deadline.
Can I verify a CNDA certificate?
Yes, Mile2 provides a certificate verification service linked from its certifications menu. Employers and candidates can use it to confirm that a credential is genuine and current. This is useful when listing the certification on a resume or in a proposal.
