What does the Registered Intrusion Analyst complexity score measure?

It measures how structurally demanding the questions are, not the official pass rate. We score every question in our Registered Intrusion Analyst bank on four measurable signals and combine them into a 1-10 score. Higher means more multi-select items, longer scenario questions, more interactive code items and deeper explanations — that is, questions that require reasoning rather than recall.

Which Registered Intrusion Analyst domain is the hardest?

By our measurement, Incident Response is the hardest domain in the Registered Intrusion Analyst bank, scoring 2.2 out of 10. The most approachable domain is Malware Analysis at 1.9.

How many questions were analysed?

We analysed 150 Foundation questions for the Registered Intrusion Analyst, split across 5 exam domains. The figures on this page are recomputed from the live bank on every crawl, so they never drift from what you actually get in a practice session.

Is this the official pass rate?

No, and we do not publish one, because vendors do not release reliable per-domain pass rates. This is our own measurement of the bank. Treat it as a map of where the demanding questions sit in the blueprint, not as a prediction of your score.

Complexity by exam domain

Higher scores mean more demanding question formats. The exam score is computed over the whole bank, not averaged across domains.

How the score is calculated

The formula is fixed and public, so anyone can reproduce these numbers from the same bank.

Every question in the Registered Intrusion Analyst bank is measured on four signals that can be read directly from the database. Each signal is expressed as a share of the questions in the domain, and the four shares are combined with fixed weights:

Multi-select questions (40% weight). Items with more than one correct answer. The candidate has to find all of them, which is the single hardest format in the bank.
Scenario questions (30% weight). Questions longer than 150 characters, which describe a situation instead of a definition and therefore test reasoning rather than recall.
Interactive questions (20% weight). Items that require reading code or a configuration snippet.
Deep explanations (10% weight). Questions whose explanation runs past 300 characters, which signals a concept with real nuance behind it.

The combined share is multiplied by ten to produce a 1-10 score. The exam-level score is computed over the whole bank rather than averaged across domains, so a small domain cannot distort the total. Figures on this page are recomputed from the live bank on every crawl.
