ISC2 Certified Information Systems Security Professional (CISSP) Certification Exam Practice Test

CISSP practice questions address security decisions across software development, cryptography, monitoring, physical protection, data handling, cloud services, and identity lifecycle management. The scenarios ask you to recognize security weaknesses, select safeguards suited to a business situation, and distinguish whether a control is merely present or is functioning effectively. They sample applied security judgment rather than testing a single technical specialty.

About the ISC2 Certified Information Systems Security Professional (CISSP) C… Exam

Effective CISSP-level security work connects technical controls with organizational risk and operational needs. Practice scenarios can require choosing secure development measures, such as keeping credentials out of source repositories; evaluating cryptographic properties, including collision resistance; and correlating events across systems to investigate possible coordinated activity. Other decisions involve resilient facility safeguards, secure media disposal, cloud shared-responsibility boundaries, and contractual protections for sensitive or regulated information. Identity lifecycle questions focus on removing access promptly when employment ends, while vulnerability scenarios distinguish an exploitable weakness from the likelihood and impact of a particular threat. In professional settings, these skills support control selection, security architecture, vendor oversight, incident detection, and risk-informed decisions about information assets. Read each scenario for its objective and constraints before selecting the control or activity that addresses them most directly.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A company is building a new application and wants to reduce the risk of exposing credentials in its source repository. Which practice is most appropriate?

  1. AStore secrets in a managed secrets service and restrict access to them
  2. BCommit credentials to source control and obscure them with a comment
  3. CShare one permanent password among all developers
  4. DPlace credentials in publicly accessible documentation
Show answerCorrect answer: A

A managed secrets service can protect credentials, provide controlled retrieval, and support rotation and auditing. Obfuscation or documentation does not securely protect secrets committed to a repository.

Question 2

An organization wants to determine whether a network security control is operating as intended, rather than merely installed. Which activity best addresses this?

  1. AReviewing the control's operating effectiveness through testing
  2. BChecking whether the control appears in the asset inventory
  3. CConfirming that the control has a purchase order
  4. DUpdating the organization's network diagram
Show answerCorrect answer: A

Testing operating effectiveness evaluates whether a control functions as designed over the relevant period. Installation or documentation alone does not establish that it works effectively.

Question 3

A team is selecting a cryptographic hash function for a new security design. Which characteristic is most important for resisting an attacker who tries to find two different inputs with the same digest?

  1. ACollision resistance
  2. BReversibility
  3. CLow memory consumption only
  4. DA fixed secret shared by every user
Show answerCorrect answer: A

Collision resistance makes it computationally infeasible to find two distinct inputs that produce the same hash digest. Hash functions are not intended to be reversible, and a shared secret is not a defining requirement of a hash function.

Question 4

A security analyst reviews a set of system events to identify activity that may indicate a coordinated attack. What is the primary benefit of correlating events from multiple sources?

  1. AIt replaces the need to investigate alerts
  2. BIt can reveal relationships or patterns that are not apparent in isolated events
  3. CIt guarantees that every malicious action will be detected
  4. DIt prevents systems from generating duplicate events
Show answerCorrect answer: B

Correlating events across systems can help analysts recognize a broader sequence or pattern, such as related authentication and network activity. It supports investigation but does not guarantee detection or eliminate the need for analyst judgment.

Question 5

An organization is designing a facility control that should continue to resist unauthorized entry if one component fails. Which design principle is most directly applicable?

  1. ADefense in depth
  2. BData minimization
  3. CSeparation of duties
  4. DOpen design
Show answerCorrect answer: A

Defense in depth uses multiple complementary safeguards so that failure or bypass of one layer does not automatically defeat the entire protection strategy. For physical access, layers may include perimeter barriers, controlled entry, and monitoring.

Question 6

An organization must dispose of a retired storage device that contains sensitive data and will not be reused. Which action is most appropriate?

  1. ADelete the files using the operating system and discard the device
  2. BApply an approved sanitization method appropriate to the device, or physically destroy it when required
  3. CRename the files and remove their directory entries
  4. DDisconnect the device and store it indefinitely without tracking
Show answerCorrect answer: B

Disposal should make the data unrecoverable to a degree appropriate for the data and device. Approved sanitization or physical destruction can achieve this; ordinary file deletion generally leaves data recoverable.

Question 7

A company is evaluating a cloud provider that will process confidential information. Which measure best helps the company understand how security responsibilities are divided?

  1. AReview the provider's shared-responsibility terms and map them to the company's duties
  2. BAssume the provider is responsible for every security task
  3. CAssume the company is responsible for maintaining the provider's physical data center
  4. DRely only on the provider's marketing description of its services
Show answerCorrect answer: A

Cloud security responsibilities are divided between provider and customer, with the split depending on the service model and configuration. Reviewing and mapping those responsibilities helps prevent gaps.

How to use this practice test

US Practice Tests provides free CISSP practice questions in sessions of up to 20 randomly selected items from its 50-question bank. Submit a session to see results, then use missed or uncertain answers to identify concepts to revisit, such as control testing, cryptographic properties, cloud responsibilities, or account deprovisioning.

Preparation tips

  • For credential-exposure scenarios, compare secure secret storage and access controls with practices that prevent secrets from entering source code or repository history.
  • Distinguish control implementation from control effectiveness: identify whether a scenario calls for inspection, testing, monitoring, or evidence that a safeguard works as intended.
  • Review cryptographic collision resistance separately from preimage resistance, and connect each property to the attack the scenario describes.
  • Map cloud responsibilities by service and task, then consider how contracts define protection duties, incident reporting, and handling of regulated information.
  • Trace identity lifecycle steps from role changes through termination, including timely account disablement and access removal.
