What this free CISSP practice includes

A timed, 25-question diagnostic drawn from the same original bank as the full product. The 25 items are distributed to mirror the real CISSP blueprint: heavier on Security and Risk Management, balanced across the technical domains, so the mix reflects the live exam rather than a random sample.

At the end you get a score, a domain-by-domain breakdown, and a clear rationale for every question that explains why the best answer is best and why the others are second-best or wrong. That is the point of a real diagnostic: it shows you which two domains to attack first, not just a number.

All eight domains sampled

Security and Risk Management, Asset Security, Security Architecture and Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, and Software Development Security, at the official weighting.

Original questions, current outline

Written by PrepClubs to the (ISC)2 CISSP Exam Outline effective April 15, 2024. Not real exam items and not scraped dumps.

Instant domain breakdown

See your score split by domain the moment you finish, so you know exactly where to focus.

A rationale for every answer

We explain the reasoning, not just the letter, so you build the management-level judgment CISSP rewards rather than memorizing.

Pass Guarantee on the full bank

Upgrade and if you sit the exam within your access window and do not pass, we extend your access another 30 days free.

Three sample CISSP questions with walkthroughs

CISSP rewards management judgment, not the sharpest technical fix. Read the stem keyword (BEST, FIRST, MOST effective) first, then work back to the options.

Sample 1: Security and Risk Management

A newly hired security manager finds a risk register that was populated two years ago and never revisited. Several listed controls have since been replaced and some threats no longer apply. What should the manager do FIRST?

A.Review and revalidate the existing register entries against the current environment before acting on them
B.Delete the register and start a fresh one from scratch
C.Begin purchasing controls for the highest-scored risks as listed
D.Present the two-year-old register to the board as the current risk picture

Answer and walkthrough

A. Risk management is a continuous cycle, so a stale register must be revalidated against today's assets, threats, and controls before it can drive any decision. This honors assess-before-act and preserves the useful history already captured. Deleting it throws away that history, buying controls from a two-year-old list acts before the risk is understood, and presenting stale data to the board misrepresents the current picture. On CISSP, the FIRST step is almost always assess or revalidate, not the most action-looking option.

Sample 2: Security Operations

During a confirmed intrusion that is not actively spreading, responders debate containment. Immediately wiping the affected servers would restore service fastest but destroy evidence needed to understand scope. Assuming the organization intends to investigate and may pursue legal action, what is the BEST containment approach?

A.Immediately reimage every affected server to resume service as quickly as possible
B.Leave the systems fully connected and continue monitoring indefinitely
C.Isolate the affected systems from the network while preserving their state so evidence and scope can be examined
D.Power the systems off abruptly to stop the attacker at once

Answer and walkthrough

C. With no active spread and an intent to investigate and possibly litigate, the best containment isolates the systems while preserving their state, halting the threat's reach yet keeping evidence intact for scope analysis and admissibility. Reimaging destroys that evidence, leaving systems connected lets the intrusion continue, and abruptly powering off can lose volatile evidence in memory. The keyword BEST plus the stated intent to litigate is what decides this one, so read the whole stem before choosing.

Sample 3: Identity and Access Management

A security manager wants terminations to reliably and immediately disable access rather than relying on IT hearing about departures informally. Which integration MOST effectively achieves reliable, timely deprovisioning?

A.Ask each manager to email the help desk when someone leaves
B.Drive account disablement automatically from the authoritative human resources system as the source of identity events
C.Run a manual account cleanup once every quarter
D.Require departing employees to disable their own accounts on their last day

Answer and walkthrough

B. Binding the identity lifecycle to the authoritative HR system means a termination recorded there triggers deprovisioning automatically, closing the gap where manual notification is forgotten or delayed. Emailing the help desk and self-disablement both depend on human memory, and a quarterly cleanup leaves access live for weeks. The keyword MOST effectively points to the systematic, authoritative source, not the manual workaround. CISSP favors the process that removes human error over the one that relies on it.

What the real CISSP exam feels like

The CISSP exam is delivered as Computerized Adaptive Testing (CAT) at a Pearson VUE test center or through online proctoring. Since April 15, 2024 that adaptive format applies to every language. You face 100 to 150 items in a maximum of 3 hours, mixing multiple-choice with advanced innovative items such as drag-and-drop and hotspot. The passing standard is a scaled 700 out of 1000, reported as pass or fail only, with no numeric score returned.

Because the exam is adaptive, you cannot skip a question and come back, and 25 of the delivered items are unscored pretest questions you cannot identify. The only sound strategy is to reason carefully on every single item. This free diagnostic is multiple-choice so you can benchmark fast, and the full bank spans a wide difficulty range per domain, which is exactly what the adaptive algorithm draws on.

Security and Risk Management is the single heaviest domain at 16 percent, and it is where management judgment is tested hardest. If your free diagnostic breakdown shows a gap there or in the operations and assessment domains, that is where the most exam points sit and where your prep time pays back the most.
