  1. An organization replicates data to a remote site every four hours. This interval represents the:

    Answer: Recovery Point Objective (RPO)

    The replication interval defines the maximum data loss the organization can tolerate, which is the definition of the Recovery Point Objective.

  2. Which type of system redundancy eliminates a single point of failure at the power supply level?

    Answer: Dual power feeds from separate utility substations

    Dual feeds from separate substations ensure that a failure at one substation does not interrupt power, unlike a UPS which only bridges a temporary outage.

  3. An IS auditor is reviewing capacity management practices. Which finding represents the GREATEST risk?

    Answer: No formal process exists to forecast resource utilization trends

    Without trend forecasting, the organization cannot proactively address capacity constraints, increasing the risk of performance degradation or outages.

  4. Which control BEST ensures the completeness of batch processing runs?

    Answer: Reconciling record counts and control totals before and after processing

    Control totals and record counts provide a mathematical verification that all input records were processed and no records were added, dropped, or duplicated.

  5. A crisis communication plan should PRIMARILY ensure that:

    Answer: Accurate and timely information reaches stakeholders during an incident

    The primary goal of crisis communication is to provide stakeholders—including employees, customers, and regulators—with accurate and timely information to manage the situation effectively.

  6. When auditing an organization's network operations center (NOC), an IS auditor should FIRST determine whether:

    Answer: Monitoring tools provide real-time alerts for threshold breaches

    Real-time alerting on threshold breaches is the foundational control that enables the NOC to detect and respond to incidents promptly.

  7. Which backup strategy provides the FASTEST recovery time while minimizing backup storage requirements?

    Answer: A combination of full and incremental backups with a recovery catalog

    A full backup combined with incremental backups and a recovery catalog balances storage efficiency with manageable restore complexity when guided by the catalog.
