The Linux Foundation certifications

Certilum covers 3 The Linux Foundation certifications, at Associate level. Each one lists the official exam format, the number of questions, the time limit and the domains with their weights.

Yes — 123 questions across the 3 certifications, each with the correct answer and a written explanation, organised by the official exam domains. No account is needed to read them.

On our measured scale, Istio Certified Associate (ICA) scores 2.1 out of 10 for difficulty. The score combines how many questions are multi-select, how many are scenario-length, and how deep the explanations are. If you want volume rather than difficulty, Prometheus Certified Associate has the largest bank, with 42 questions.

We have the published price for 3 of the 3 certifications. Prices change by region and by provider, so the exact figure is on each certification's exam cost page, sourced from the vendor's own pricing page.

It varies by exam, and the table below shows the published format for each one: question count, time limit, passing score and number of domains. Where a vendor does not publish a passing score, the cell says so rather than showing a number we cannot source.

Start from the role you want, not the vendor. Within The Linux Foundation the options sit across Software Development. After that, compare the exam format and the domain weights: the heaviest domain is where the pass is decided, and the difficulty score tells you how demanding the questions in each certification actually are.
