About this exam

The EC-Council Certified DevSecOps Engineer (ECDE) is a vendor certification, exam code 312-97, aimed at people who build or secure automated software delivery pipelines. EC-Council positions it for DevOps engineers, software engineers and testers, application security professionals, IT security professionals, and cyber security engineers or analysts, plus anyone with prior application security knowledge who wants to move into a DevSecOps role. The source also lists CASE-certified professionals among the intended audience. The exam is delivered online through the EC-Council exam portal as 100 multiple-choice questions in a four-hour window, with a 70% passing score. Content follows the course outline: DevOps culture and principles; DevSecOps foundations and the shift from traditional security approaches; then the pipeline stages of plan (security requirements and threat modeling), code (secure coding and IDE controls), build and test (automated SAST and DAST in CI), release and deploy (secure deployment, infrastructure as code security, container security), and operate and monitor (logging, monitoring, incident detection and response, SIEM). Preparation is course-based: EC-Council states that applicants must be aware of application security concepts and must enroll in its DevSecOps course to be eligible, and that the exam is based on that program's material and practical training. The course is instructor-led, described as 70% lab-focused with more than 100 online and offline labs (32 on-premises, 32 AWS Cloud, 29 Microsoft Azure) delivered as a three-day program.

What you'll study

Common questions

About ECDE preparation

What is the exam format and how long do I have?

EC-Council lists 100 multiple-choice questions and a duration of four hours, delivered online through the EC-Council exam portal. That averages under two and a half minutes per question, so plan to move steadily and flag anything that needs a second pass rather than stalling on one item.

What score do I need to pass?

The passing score is 70%, so you need at least 70 of the 100 questions correct. There is no published partial credit or domain-level scoring, so treat every domain as capable of carrying you over or under the line and avoid writing off any single stage of the pipeline.

Am I eligible to sit the exam?

EC-Council states that applicants must be aware of application security concepts and must enroll in the DevSecOps course offered by EC-Council to be eligible to take the ECDE exam. If you are self-studying, check current eligibility terms with EC-Council directly before booking, since this page cannot confirm them.

How difficult is the exam, and what trips candidates up?

The exam is broad rather than deeply mathematical: seven modules spanning culture, foundations, and five pipeline stages, with tool categories such as SAST, DAST, IAST, SCA, RASP, IaC scanning, and SIEM. Common failure modes are memorizing product names without knowing which pipeline stage or test class each belongs to, and underestimating the plan and operate modules because they feel less technical.

What is the recommended study order?

Follow the course sequence: DevOps culture, then DevSecOps foundations, then plan, code, build and test, release and deploy, operate and monitor. The later stages assume the vocabulary from the earlier ones, and the pipeline modules map cleanly onto exam questions about where a given control belongs and what it detects.

How should I use the labs when preparing?

EC-Council describes the course as 70% lab-focused with more than 100 labs across on-premises, AWS, and Azure environments. Use them to connect a tool to its purpose: run a static analysis scan, a dynamic scan, a dependency check, and an image scan, and note what each one finds and where in the pipeline it runs.

Where can I find ECDE practice questions?

Practice questions help most after you can explain each pipeline stage and the security controls that belong to it. Work domain by domain, write a one-line justification for every answer you choose, and revisit any item where your reasoning was right but slow, since timing is a real constraint at 100 questions in four hours.

Does this page or its questions come from EC-Council?

No. This is original study material written for candidates preparing for the ECDE exam. It is not produced, reviewed, sponsored, or endorsed by EC-Council, and it does not reproduce any official courseware or question bank. Always confirm exam logistics and policy details against EC-Council's own published certification pages.
