CISA Timed Hard Questions — 25 Difficult Questions

Question 1

Based on the exhibit, which control is most likely missing to prevent this type of event?

Accepted Answer

Implementing account lockout after three failed attempts. The exhibit describes a brute-force attack against an SSH service, where an attacker repeatedly attempts to guess credentials. Implementing account lockout after three failed attempts is the most direct control to prevent this type of event, as it halts further login attempts after a threshold, stopping the attack in its tracks regardless of password strength or patching.

Answer

Applying the latest security patches to the SSH service

Answer

Disabling direct root login via SSH

Answer

Enforcing strong password complexity

Question 2

During an IT audit, the auditor discovers that the IT department has not conducted a business impact analysis (BIA) for three years. The organization's disaster recovery plan (DRP) is based on the previous BIA. The IT manager argues that the DRP is still valid because no major changes have occurred. What should the auditor recommend?

Accepted Answer

Recommend that a new BIA be conducted to validate and update the DRP.. A business impact analysis (BIA) is the foundation of a valid disaster recovery plan (DRP). Without a current BIA, the DRP may not reflect the organization's current critical processes, recovery time objectives (RTOs), or recovery point objectives (RPOs). Even if no major changes are perceived, subtle shifts in dependencies, resource availability, or regulatory requirements can render the DRP ineffective. Therefore, the auditor should recommend conducting a new BIA to validate and update the DRP.

Answer

Accept the IT manager's rationale and close the finding.

Answer

Recommend terminating the current DRP until the BIA is completed.

Answer

Recommend accepting the risk and documenting the decision.

Question 3

Based on the exhibit, the IS auditor is reviewing access to the payroll folder. Which of the following is the MOST significant finding?

Accepted Answer

Potential excessive privileges for user jdoe due to overlapping permissions. Option D is the most significant finding because user jdoe has overlapping permissions from multiple group memberships (e.g., HR_Managers and Payroll_Admin), which can result in unintended cumulative effective permissions. In Windows NTFS, effective permissions are the sum of all allowed permissions from each group, minus any explicit denies, so overlapping group memberships often grant more access than intended, violating the principle of least privilege.

Answer

Internal_Audit group has Read access to payroll data

Answer

User asmith has only Read access to payroll

Answer

HR_Managers group has Full Control over payroll

Question 4

Which THREE of the following are key elements that should be included in a risk assessment report for information systems?

Accepted Answer

Identification of critical assets and their vulnerabilities. A is correct because a risk assessment report must identify critical assets and their vulnerabilities to establish the scope and basis for risk analysis. Without this, the report cannot prioritize which systems require immediate attention or justify subsequent control recommendations.

Answer

List of all vendors and their contract terms

Answer

Detailed budget for implementing security controls

Question 5

During an incident response exercise, the IT team discovers that the failover to the disaster recovery (DR) site failed because the DR site's storage area network (SAN) was not zoned correctly for the replicated data. Which of the following controls would BEST prevent this issue?

Accepted Answer

Conducting regular disaster recovery testing including full failover. Option D is correct because regular disaster recovery testing that includes a full failover is the only control that directly validates that the DR site's SAN zoning is correctly configured to accept replicated data. Without such testing, misconfigurations like incorrect zone sets or missing WWPN (World Wide Port Name) mappings in the SAN fabric remain undetected until an actual failover is attempted. This aligns with the CISA emphasis on testing recovery procedures to ensure business continuity.

Answer

Maintaining a configuration management database (CMDB)

Answer

Implementing a change management process for SAN configurations

Answer

Using automated replication monitoring tools

Question 6

An IT auditor is reviewing the business continuity plan (BCP) for a financial services firm. The plan includes a hot site that is shared with another organization under a reciprocal agreement. Which of the following findings should be of MOST concern to the auditor?

Accepted Answer

The reciprocal agreement does not guarantee exclusive use of the hot site during a disaster. Option C is correct because a reciprocal agreement for a shared hot site does not guarantee exclusive access during a disaster. If both organizations declare a disaster simultaneously, the site may become oversubscribed, leading to resource contention and potential failure of the BCP. This directly undermines the recovery capability, making it the most critical finding.

Answer

The hot site uses a different internet service provider than the primary site

Answer

The hot site has not been tested in the past 12 months

Answer

The hot site is located in the same seismic zone as the primary site

Question 7

During a post-implementation review of a new HR system, the auditor finds that the system's disaster recovery plan (DRP) was not tested before go-live. Which of the following is the BEST recommendation?

Accepted Answer

Conduct a DRP test immediately and document results. The DRP should be tested as part of the implementation. Option B is a temporary fix; Option C is not proactive; Option D is not sufficient.

Answer

Accept the risk because the system is new

Answer

Implement a backup procedure for the system

Answer

Schedule a DRP test within the next six months

Question 8

A company is implementing a privileged access management (PAM) system. Which of the following is the MOST important control to prevent lateral movement after a privileged account is compromised?

Accepted Answer

Implement just-in-time (JIT) privilege elevation. Just-in-time (JIT) privilege elevation is the most important control to prevent lateral movement because it eliminates standing privileged access. By granting temporary, time-bound privileges only when needed, JIT reduces the attack surface and ensures that even if an attacker compromises a privileged account, they cannot use those credentials to move laterally to other systems after the access window expires. This directly addresses the root cause of lateral movement: persistent privileged credentials that can be reused across the network.

Answer

Enforce multi-factor authentication for all privileged accounts

Answer

Monitor and record all privileged sessions

Answer

Rotate passwords after each use

Question 9

Which THREE of the following are key components of an effective information security awareness program? (Choose three.)

Accepted Answer

Phishing simulation exercises. Phishing simulation exercises are a key component of an effective information security awareness program because they provide hands-on, practical experience in identifying and responding to real-world phishing attempts. By simulating attacks, organizations can measure employee susceptibility, reinforce training, and reduce the risk of successful social engineering attacks. This proactive approach helps build a security-conscious culture and directly addresses the human factor in cybersecurity.

Answer

Reward program for reporting incidents

Answer

Annual one-time training for all employees

Question 10

An organization is implementing a new ERP system. The project sponsor requests a change that will significantly increase project scope without additional budget. Which of the following is the BEST action for the project manager?

Accepted Answer

Initiate the formal change control process and escalate to the steering committee.. The project manager must follow the formal change control process to evaluate the impact of a scope change that lacks additional budget. Escalating to the steering committee is appropriate because they have the authority to approve or reject changes that affect project constraints, ensuring alignment with organizational governance and IT strategy.

Answer

Accept the change and adjust the project timeline accordingly.

Answer

Implement the change and inform the steering committee later.

Answer

Reject the change because it is outside the original scope.

Question 11

An IS auditor is reviewing the system development life cycle (SDLC) for a custom application. The project manager has decided to skip the design phase and proceed directly from requirements to coding. Which of the following risks are MOST likely to increase as a result? (Choose two.)

Accepted Answer

Inadequate security controls.. Skipping the design phase means that security requirements are never formally defined or integrated into the system architecture. Without a security design, controls such as authentication, authorization, encryption, and input validation are likely to be omitted or implemented ad hoc, leading to inadequate security controls. This directly increases the risk of vulnerabilities that could be exploited in production.

Answer

Delays in project schedule.

Answer

Increased cost due to rework.

Answer

Increased number of defects during unit testing.

Question 12

Based on the backup logs, the backup administrator notices that the incremental backup job failed due to insufficient storage. Which TWO actions should the administrator take to resolve the immediate issue and prevent recurrence?

Accepted Answer

Free up space on the backup storage device by removing old backup sets manually. Option A is correct because freeing up space on the backup storage device by removing old backup sets immediately resolves the insufficient storage issue that caused the incremental backup job to fail. This is a direct, short-term fix that reclaims capacity without altering backup schedules or configurations.

Answer

Check network bandwidth between the backup server and storage device

Answer

Increase the frequency of incremental backups to reduce data volume per job

Answer

Investigate and resolve the file-in-use warnings from the full backup job

Question 13

Refer to the exhibit. A security analyst notices that users on the INSIDE network (10.1.1.0/24) can browse HTTPS websites but cannot resolve domain names. What is the most likely cause?

Accepted Answer

The ACL only permits DNS traffic to host 10.2.2.10, but users need to query a different DNS server. The exhibit shows an ACL that permits DNS traffic (UDP port 53) only to host 10.2.2.10. Since users can browse HTTPS (TCP/443) but cannot resolve domain names, the ACL is blocking DNS queries to any other DNS server. Option B correctly identifies that the ACL restricts DNS to a single server, and if users are configured to query a different DNS server, resolution fails.

Answer

The ACL denies TCP traffic to port 443

Answer

The DNS server at 10.2.2.10 is unreachable

Answer

The OUTSIDE interface has no security-level configured correctly

Question 14

Which THREE of the following are common challenges when integrating a software package with existing legacy systems? (Select exactly three.)

Accepted Answer

Lack of documented application programming interfaces (APIs). Legacy systems often lack well-documented or standardized APIs, making it difficult to establish reliable interfaces for integration. Without clear API documentation, developers must reverse-engineer communication protocols or rely on outdated methods like screen scraping, which increases integration risk and effort.

Answer

Availability of modern integration middleware

Answer

Need for custom development to bridge the gap

Question 15

The exhibit shows a log entry from a domain controller. The IS auditor is investigating account lockout issues. What is the MOST likely cause of this event?

Accepted Answer

Multiple failed authentication attempts from the backup server. The log entry shows a failed authentication attempt from the backup server's IP address (10.0.0.15) using the service account 'svc_backup'. The event ID 4625 indicates an account logon failure, and the 'Failure Reason' field explicitly states 'Unknown user name or bad password'. Since the account name is correct, the most likely cause is multiple failed authentication attempts (e.g., due to a stale or incorrect password cached in the backup software) leading to account lockout, not a single event.

Answer

The service account password has expired

Answer

The service account does not exist

Answer

The service account has been disabled by an administrator

Question 16

During a system development project, the project manager notices that the actual cost is significantly higher than the planned cost at the 50% completion point. The earned value (EV) is $500,000, the actual cost (AC) is $600,000, and the planned value (PV) is $550,000. Which of the following is the MOST appropriate action?

Accepted Answer

Conduct a root cause analysis to identify the reasons for cost overrun. Option C is correct because the project is over budget (EV $500K vs AC $600K) and behind schedule (EV $500K vs PV $550K). Before taking corrective action, the project manager must first perform a root cause analysis to understand why costs are exceeding planned values. This aligns with the CISA’s emphasis on identifying the underlying cause of variances before implementing changes to scope, budget, or schedule.

Answer

Request additional budget from senior management

Answer

Reduce the project scope to align with the budget

Answer

Crash the project schedule to make up for lost time

Question 17

Which TWO are primary objectives of an identity and access management (IAM) program? (Select exactly 2.)

Accepted Answer

Ensuring appropriate access to resources.. Option A is correct because the primary objective of an IAM program is to ensure that the right individuals have access to the appropriate resources at the right time for the right reasons. This is achieved through authentication, authorization, and access control mechanisms such as Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC). Without this, the organization cannot enforce security policies or maintain audit trails.

Answer

Encrypting data at rest and in transit.

Answer

Patching software vulnerabilities.

Answer

Monitoring network traffic for anomalies.

Question 18

A security architect is designing a data classification schema for a multinational corporation. Which combination of factors is MOST critical for determining the classification level of a data asset?

Accepted Answer

Legal, regulatory, and business impact if disclosed.. The classification level of a data asset is primarily determined by the potential harm that could result from its unauthorized disclosure, modification, or loss. Legal, regulatory, and business impact factors—such as compliance with GDPR, HIPAA, or PCI DSS—directly dictate the required confidentiality, integrity, and availability controls. Without assessing these impacts, any classification scheme would be arbitrary and fail to align with organizational risk tolerance.

Answer

Data volume and storage location.

Answer

Data format and encryption status.

Answer

Data creation date and last access time.

Question 19

Based on the exhibit, what should the IS auditor MOST likely recommend?

Accepted Answer

Review the criteria for emergency changes and enforce proper classification. The exhibit shows changes classified as 'emergency' bypassing the standard approval process. The IS auditor's primary concern is that emergency changes may be misclassified to avoid proper review, increasing risk. Option D is correct because it addresses the root cause: reviewing the criteria for emergency changes and enforcing proper classification ensures that only truly urgent changes bypass standard controls, while all others follow the required approval path.

Answer

Investigate whether any changes are missing from the log

Answer

Immediately block all direct production access for developers

Answer

Require all changes to go through the standard approval process

Question 20

Which THREE of the following are key metrics to include in a disaster recovery test report? (Select exactly 3.)

Accepted Answer

Amount of data lost (actual vs. RPO). Option A is correct because the amount of data lost (actual vs. RPO) directly measures whether the recovery process met the Recovery Point Objective. This metric validates the effectiveness of backup frequency and replication lag, which is critical for determining if the DR plan preserved data integrity within acceptable loss limits.

Answer

Cost per incident

Answer

Number of personnel involved
