Questions people ask
How does GCED relate to the GIAC Security Essentials (GSEC) certification?
GCED builds on the security skills measured by the GSEC certification, providing more advanced technical skills needed to defend the enterprise environment. While GSEC is not a mandatory prerequisite, it is a recommended foundation.
Is there a hands-on or lab component in the GCED exam?
The GCED exam is a proctored, web-based exam that objectively measures knowledge and hands-on cybersecurity skills. While it does not use the CyberLive format, it assesses practical skills through scenario-based questions.
What is the retake policy for the GCED exam?
GIAC does not publish a specific retake policy for the GCED exam. Candidates should refer to their GIAC account for details on exam attempts and any applicable waiting periods.
How soon will I receive my GCED exam results?
GIAC does not publish a specific timeline for score reporting. Candidates should check their GIAC account for score availability after the exam attempt.
What job roles does the GCED certification map to?
GCED is designed for incident responders, penetration testers, SOC engineers and analysts, and network security professionals who need advanced technical skills to defend enterprise environments.
Can I recertify GCED by passing a different GIAC exam?
Yes, GIAC allows renewal by retaking the GCED exam or by earning 36 CPE credits over four years. Passing a different GIAC exam may also contribute to CPE credits, but it does not automatically renew GCED unless it is the same exam.
Are there regional differences in GCED exam delivery?
GIAC offers remote proctoring through ProctorU and onsite proctoring through PearsonVUE, which are available in many regions. Specific availability may vary by location.

Ask, answer, and vote. Every question has its own thread.
A question, and the idea behind it
Every question comes from a concept
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.
The visual book
See it once. Carry it into the exam.
The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

Answer it with the picture beside you
This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.
It teaches · it does not count
A smartphone uses AI to unlock when the owner looks at the camera. Which AI capability is being used?
AImage classification
BFacial recognition

DObject detection
Look at the five steps. Detect finds a face, align straightens it, encode turns it into numbers, search compares it with a stored face, and decide answers one question: is this the same person? Classification would only say “a face”. Detection would only draw a box. Neither decides whose.
Then the page shuts, and it starts counting
The same questions come back with the book closed — that run is the one that counts. After it, your coach picks one thing for tonight, sized to the time you have, and brings pages back before you lose them.
