Don't Just Study DevOps.
Practice Operating It.
Triage realistic production failures, build local containerized infrastructure on your laptop, and build verified proof of what you can actually operate.

Practice Operating Real Systems.
Not Just Multiple Choice.
Everything you need to level up from textbook knowledge to battle-tested production reliability.
Container orders-api terminated unexpectedly. kubectl describe pod reports Exit Code 137. What caused this?
Why Engineers Choose OpsQuiz
Passive videos and toy exercises do not prepare you for real 2 AM production outages. OpsQuiz gives you hands-on incident triage, local enterprise architecture, and verified cryptographic competence.
Active Production Triage, Not Video Watching
You cannot learn incident response by watching someone else click buttons. OpsQuiz puts you inside simulated production failures with Kubernetes CrashLoops, NGINX latency spikes, and Terraform state drifts where you diagnose and fix under realistic MTTR timers.

[DIAGNOSED] OOMKilled limit: 512Mi · Heap ceiling: 1024Mi · Patch Ready
Tamper-Proof Proof of Competence
Hiring managers ignore unverified course completion PDFs. Your OpsQuiz SRE Skill Passport generates cryptographic SHA-256 verification seals linked to your actual terminal scores and triage percentiles.

Top 4% Global MTTR Benchmark
15 Local Architecture Labs
Build multi-tier containerized architectures on your laptop using Docker, Kubernetes, and Helm. Every lab includes Senior Staff model architectures and solutions.
1v1 Real-Time Arena Battles
Test your speed and composure against peer engineers worldwide in live, timed head-to-head incident duels. Build instinctive speed under production pressure.
OPS AI Socratic Commander
Get root-cause guidance that leads you to the answer without giving it away. Learn how Senior Staff SREs break down complex distributed anomalies.
The Paradigm Shift in DevOps Preparation
- ×Binge-watching 40 hours of passive video lectures without touching real code
- ×Unverifiable PDF certificates that carry zero weight with top tech hiring teams
- ×Toy 'hello world' tutorials that collapse when facing high distributed traffic
- ×Panic and high MTTR during real production outages due to lack of muscle memory
- ✓Hands-on outage triage in interactive simulation labs with live MTTR scoring
- ✓Cryptographically verified SRE Skill Passport that proves your operational ability
- ✓15 local production-grade projects built with Senior Staff model architecture
- ✓Deep instinctive calm during production incidents built through 1v1 Arena battles
How You Practice On OpsQuiz
A structured, 4-stage journey taking you from identifying your gaps to building production-grade infrastructure.
Diagnose & Benchmark
Identify where your knowledge breaks before an interviewer or outage does.
Deep-Dive & Architecture
Master the underlying mechanics through plain-language tutorials and system design.
Troubleshoot & Operate
Step into the shoes of an on-call engineer resolving active production failures in real time.
Build & Defend
Prove what you can actually build on your own machine and articulate in interviews.

- Full curriculum spanning Linux, Docker, Kubernetes, and PGA Monitoring Stack
In Kubernetes, container resource limits dictate how the Linux kernel
schedules CPU cycles and allocates memory through cgroups v2.
A critical rule: setting memory limits equal to requests assigns
the pod to Guaranteed QoS, preventing eviction under node memory pressure.
When a process exceeds its memory ceiling, the kernel issues SIGKILL (exit code 137).
Three ways to go deeper.
One Core account.
One sign-in with Google - your access follows you to any device, no re-purchasing required.
Walk in ready, not guessing.
A timed camera-and-mic session with AI follow-up questions, so you find out where you freeze up before the real interview does.
Practice DevOps Like You Actually Work
Why use OpsQuiz when you have ChatGPT and YouTube? Because information is a commodity. Real operational competence is built by solving realistic problems under constraints.
Think First, No Spoon-Fed Answers
Passive reading creates the illusion of competence. In real production incidents, no one gives you the answer first. We challenge you to diagnose, reason, and troubleshoot under constraints.
Real Scenarios Over Syntax Trivia
Nobody hires an SRE because they memorized 50 CLI flags. Every question, playbook, and project is based on genuine production failures: OOMKilled pods, DNS routing loops, and cascaded outages.
AI as a Coach, Not an Answer Machine
ChatGPT dumps the solution and robs you of the learning moment. OPS provides Socratic hints, asking probing questions to guide your diagnosis without doing the work for you.
Evidence of What You Can Actually Do
Quizzes test memory; projects test execution. Build a permanent, verifiable DevOps Skill Passport tracking completed architectures, incident postmortems, and hands-on labs.

The UI is clean and the quiz idea for DevOps is very helpful for beginners. [...] Great work, this can become a very helpful platform for DevOps learners.
Really nice project! Already bookmarked, will be using it frequently.
The interface is super clean and distraction-free. I love how I can quickly jump into quizzes without creating an account. Definitely one of the better practice websites I've used.
I spent just 20–30 minutes every day practicing on OpsQuiz. It boosted my confidence a lot. The dark mode is a nice bonus too!
Looking forward to seeing more topics added.
