Free CISSP: Certified Information Systems Security Professional Exam Questions and Answers
CISSP is the credential most often named in senior security job adverts, and the one whose difficulty is usually misunderstood: it is adaptive, so the exam adjusts to your answers and ends anywhere between 100 and 150 items within a three-hour window. The pass mark is 700 out of 1000 on a scaled score, and registration is $749 in the Americas. ISC2 requires five years of paid work across at least two of the eight domains — one year waivable with a relevant degree or approved credential — and you can sit the exam first, becoming an Associate of ISC2 with six years to earn the experience. Security and Risk Management is the largest domain at 16%. Candidates consistently report the hard part is not technical depth but answering as a manager rather than an engineer.

Question #1
What is the FIRST step when developing an Information Security Continuous Monitoring (ISCM) program?
Please select an optionIncorrectCorrect answer: D
NIST SP 800-137 starts with defining an ISCM strategy grounded in the organization's risk tolerance; that strategy then drives the metrics, frequencies, architecture and data collection that follow.
Was this answer correct?Question #2
An organization has been collecting a large amount of redundant and unusable data and filling up the storage area network (SAN). Management has requested the identification of a solution that will address ongoing storage problems. Which is the BEST technical solution?
Please select an optionIncorrectCorrect answer: A
Because the problem is redundant data accumulating on the SAN, deduplication eliminates duplicate copies and frees the most space. Compression and caching mainly aid performance, while replication increases rather than reduces storage use.
Was this answer correct?Question #3
In which process MUST security be considered during the acquisition of new software?
Please select an optionIncorrectCorrect answer: B
Security requirements must be stated in the request for proposal so vendors bid against them; requirements introduced later in negotiation, selection or implementation are costly and often cannot be met.
Was this answer correct?Question #4
Wireless users are reporting intermittent Internet connectivity. Connectivity is restored when the users disconnect and reconnect, utilizing the web authentication process each time. The network administrator can see the devices connected to the APs at all times. Which of the following steps will MOST likely determine the cause of the issue?
Please select an optionIncorrectCorrect answer: A
Clients stay associated at the AP but lose Internet access until they reauthenticate through the portal, which is the signature of an expiring captive-portal session timer. An encryption or passphrase mismatch would prevent association entirely.
Was this answer correct?Question #5
Two computers, each with a single connection on the same physical 10 gigabit Ethernet network segment, need to communicate with each other. The first machine has a single Internet Protocol (IP) Classless Inter-Domain Routing (CIDR) address of 192.168.1.3/30 and the second machine has an IP/CIDR address 192.168.1.6/30. Which of the following is correct?
Please select an optionIncorrectCorrect answer: D
A /30 mask leaves two usable hosts per subnet, placing 192.168.1.3 in 192.168.1.0/30 and 192.168.1.6 in 192.168.1.4/30, so the hosts are on different layer 3 networks. Traffic between different networks must be routed, not bridged.
Was this answer correct?Question #6
A database server for a financial application is scheduled for production deployment. Which of the following controls will BEST prevent tampering?
Please select an optionIncorrectCorrect answer: B
Input and data validation stops malformed or malicious values from altering stored records, directly preventing tampering. Logging and monitoring only detect tampering after it occurs.
Was this answer correct?Question #7
he security organization is loading for a solution that could help them determine with a strong level of confident that attackers have breached their network. Which solution is MOST effective at discovering successful network breach?
Please select an optionIncorrectCorrect answer: B
A honeypot has no legitimate business use, so any interaction with it is strong evidence of an intruder already inside the network, with essentially no false positives. IDS and IPS alerts require interpretation and frequently produce noise.
Was this answer correct?Question #8
Which of the following is established to collect information Se eee ee ee nation readily available in part through implemented security controls?
Please select an optionIncorrectCorrect answer: C
ISCM is the program established to continuously collect security-related information and maintain awareness of the security posture, which implemented controls feed. A security assessment report or risk assessment report only documents findings at a point in time.
Was this answer correct?Question #9
An organization has implemented a password complexity and an account lockout policy enforcing five incorrect logins tries within ten minutes. Network users have reported significantly increased account lockouts. Which of the following security principles is this company affecting?
Please select an optionIncorrectCorrect answer: A
Locking legitimate users out of their accounts denies them timely access to systems and data, which is a loss of availability. Confidentiality and integrity are unaffected by the lockouts.
Was this answer correct?Question #10
Which security evaluation model assesses a product's Security Assurance Level (SAL) in comparison to similar solutions?
Please select an optionIncorrectCorrect answer: C
The Common Criteria evaluates products against protection profiles and assigns assurance levels, allowing comparison of evaluated products. PCI-DSS, ISO 27001 and COBIT assess organizations and processes, not product assurance.
