20+ practice questions focused on Information Systems Operations and Business Resilience — one of the most tested topics on the Certified Information Systems Auditor CISA exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Information Systems Operations and Business Resilience PracticeAn organization experiences a critical system failure during non-business hours. The IT team discovers that the last full backup was 48 hours ago, and the incremental backups for the past 24 hours are corrupted. The recovery time objective (RTO) for this system is 4 hours, and the recovery point objective (RPO) is 1 hour. Which of the following is the MOST immediate concern?
Explanation: The RPO of 1 hour means the organization can tolerate losing at most 1 hour of data. With the last full backup 48 hours old and incremental backups for the past 24 hours corrupted, the usable recovery point is at least 24 hours old, resulting in data loss far exceeding the 1-hour RPO. This gap between actual and acceptable data loss is the most immediate concern because it directly violates the business continuity requirement.
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?
Explanation: 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.
A company is designing its backup strategy for a critical database that must be available 24/7. The database experiences high transaction volumes. Which backup method minimizes data loss while allowing continuous operations?
Explanation: Online backup with transaction log backups (Option C) is correct because it allows the database to remain fully operational (24/7 availability) while capturing every committed transaction in the transaction log. In the event of a failure, you can restore the most recent full backup and then apply all subsequent transaction log backups to recover to the exact point of failure, minimizing data loss to only uncommitted transactions.
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?
Explanation: 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.
A company's backup policy requires that backup tapes be stored offsite for at least one year. During an audit, the auditor finds that the offsite storage facility is not access-controlled and backup tapes are not encrypted. Which of the following is the auditor's BEST recommendation?
Explanation: The core issue is that backup tapes contain sensitive data and are stored in an uncontrolled environment. Encrypting the tapes before transport ensures that even if the physical security of the offsite facility is compromised, the data remains confidential. This directly addresses the risk of unauthorized access to the data, which is the primary concern, and is a cost-effective, immediate control that does not disrupt operations.
