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?
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.
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.

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.

Get root-cause guidance that leads you to the answer without giving it away. Learn how Senior Staff SREs break down complex distributed anomalies.
A structured, 4-stage journey taking you from identifying your gaps to building production-grade infrastructure.
Identify where your knowledge breaks before an interviewer or outage does.
Master the underlying mechanics through plain-language tutorials and system design.
Step into the shoes of an on-call engineer resolving active production failures in real time.
Prove what you can actually build on your own machine and articulate in interviews.

New here? Follow our guided learning pathPractical DevOps tutorials with your own notes, highlights, and OPS, an AI study companion that helps you understand concepts, get examples, and learn deeper.
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).
One sign-in with Google - your access follows you to any device, no re-purchasing required.
A timed camera-and-mic session with AI follow-up questions, so you find out where you freeze up before the real interview does.
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.
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.
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.
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.
Quizzes test memory; projects test execution. Build a permanent, verifiable DevOps Skill Passport tracking completed architectures, incident postmortems, and hands-on labs.
Loved by engineers preparing for interviews, learning Kubernetes and Docker, and growing their DevOps careers.
Questions answered, growing every week
An excellent user interface, everything is easily accessible, and learning is made quite simple. Keep it up!
Awesome mate.
I checked out OpsQuiz and found it quite comprehensive for DevOps practitioners. Good work!
Highly recommended for college students.
Simple, fast, and actually useful, just quality questions and instant feedback. Exactly what I needed for quick revision.

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.
