Zscaler's ZDTE exam blueprint header states the exam is 60 questions at Professional Level.
90 minutes total, per the same official blueprint - about 90 seconds per question.
Zscaler's exam page lists US$300 (1 credit) per attempt, and the fee is non-refundable and non-transferable.
Zscaler certifications expire two years after the date earned; recertification means passing the current version of the exam.
What the ZDTE Exam Actually Tests
ZDTE is the engineer credential in Zscaler's certification program - the final step in the Zscaler for Users - Engineer (EDU 202) learning path. Where the administrator credential stops at deployment, ZDTE confirms an experienced security professional's knowledge of advanced configuration across the platform services, security services, and data protection and management/logging layers of the Zscaler zero trust platform.
Zscaler's published outcomes read like an engineer's job description: integrate with advanced identity services, configure advanced connectivity options for sending traffic to the Zero Trust Exchange, deploy Zscaler Private Service Edge, configure DNS security, firewall, private app segmentation, browser isolation, AppProtection, deception, and DLP, and explore advanced digital experience monitoring.
The blueprint weights six domains: Architecture and Design 22%, Implementation and Deployment 22%, Operations and Monitoring 16%, Troubleshooting and Support 15%, Security and Compliance 14%, and Automation and Optimization 11%. The objectives inside them are scenario-shaped - choosing between GRE, IPSec, PAC, and Zscaler Client Connector forwarding for a given user group, sizing App Connectors for bandwidth and high availability, building application segments, and wiring Nanolog Streaming Service feeds into a SIEM.
Zscaler calls this 'an online proctored exam' in the blueprint itself and recommends it for candidates with a minimum of one year of Zscaler platform experience, including hands-on ZIA, ZPA, and ZDX. One honesty note: Zscaler does not publish a numeric passing score - the official FAQ states it does not reveal specific cut scores. Anyone quoting an exact ZDTE pass percentage is guessing.
OnVUE at Home or a Pearson Test Center
Pearson VUE's Zscaler program page states the delivery plainly: Zscaler offers two methods of exam delivery - in-person at Pearson Authorized Test Centers and online via the OnVUE platform. Both routes are scheduled through your Pearson web account, and the ZDTE blueprint itself describes the exam as online proctored. One restriction worth knowing: Zscaler's FAQ says OnVUE online-proctored exams are not offered in China, and exams are not offered in any format in Cuba, Iran, North Korea, Russia, Syria, or Ukraine, nor in Quebec, Canada.
The at-home route carries Pearson's published OnVUE requirements: Windows 10 or macOS 14 or higher, a working webcam, microphone, and speaker with no headphones, one display only, at least 6 Mbps down and 2 Mbps up, and the ability to close every application except OnVUE. Virtual machines, phones, tablets, smart devices with recording or AI features, secondary displays, VPNs, and corporate networks are prohibited. Check-in opens 30 minutes before the appointment with technology checks, photo and ID capture, and a 360-degree room scan - and failing the requirements on exam day can mean immediate cancellation and forfeiture of the fee, so the system test belongs on the exact device and network you will use.
What the ZDTE Attempt Costs
Zscaler's pricing is blunt: $300 USD per attempt, listed as US$300 (1 credit) on the exam page, and the registration fee is non-refundable and non-transferable. Before you can book, you need a Zscaler Cyber Academy account and your Zscaler Client Candidate ID (ZCID), which is what links your Pearson web account to your certification record.
Retakes cost the full $300 again, and the official retake policy has teeth. One attempt per registration. After a failed first attempt you wait 7 calendar days. The waits then escalate - 15 days, 30 days, then 60 and 60 days - with a maximum of five retakes inside twelve months of the first attempt. A seventh attempt only opens a full year after the first, and anything beyond the sixth retake is case-by-case. You also cannot retake an exam you already passed except for an approved recertification. For an engineer staring at a deployment calendar, a failed attempt is a schedule problem as much as a fee problem - which is exactly what a handled sitting removes.

Safety, Risk, and Straight Talk
Zscaler is direct about enforcement: exams are computer scored immediately, and the final score is transmitted to your Zscaler Cyber Academy account only after a statistical analysis that looks for security issues, including the use of non-approved preparation materials - a flagged issue means an invalidation notice. Zscaler's exam day rules add that violations can mean termination, invalidated results, forfeited fees, and a ban from future Zscaler exams. Any provider who pretends those enforcement lines do not exist is not being honest with you.
What we control is the quality, discretion, and privacy of the engagement: an honest feasibility answer before anything starts, a structured execution plan, and a fee that follows the result. If your situation makes the service a bad fit, we tell you before you spend anything.
Pay After the Pass Posts
The payment model is the service. You do not pay the service fee upfront and hope. Exam Assist handles your ZDTE sitting end to end, and the service fee is due only after the agreed result posts.
That structure is deliberate. It moves the risk off your side of the table and onto ours, and it keeps the engagement honest: if the agreed result does not post, the service fee does not either.
Candidate Feedback
ZDTE was the gate on a zero-trust migration contract. They confirmed the format against Zscaler's blueprint, handled the sitting, and I paid after the pass posted.
I live in ZIA and ZPA configs, not in exam scheduling portals. Having the ZDTE sitting handled end to end turned a six-month delay into a posted result.
The escalating retake waits were the decider. A failed exam meant $300 gone and weeks of calendar damage. The fee-after-result model made the decision easy.
