Peak bandwidth usage is the most helpful in defining an early-warning threshold associated with insufficient network bandwidth. Peak bandwidth usage is the maximum amount of data that is transferred over a network connection at a given time. It indicates the highest demand and stress on the network resources and capacity. By monitoring the peak bandwidth usage, the organization can identify the potential bottlenecks, slowdowns, and disruptions that may occur due to insufficient network bandwidth. The organization can also plan and allocate the network bandwidth accordingly to meet the peak demand and avoid service degradation. The other options are not as helpful as peak bandwidth usage, as they do not reflect the actual or potential network performance issues that may arise due to insufficient network bandwidth. References = Risk and Information Systems Control Study Manual, Chapter 4: Risk and Control Monitoring and Reporting, Section 4.3: Key Risk Indicators, page 197.

The person or entity who should be primarily responsible for performing user entitlement reviews is the data owner. A user entitlement review is a process that verifies and validates the access rights and privileges of the users to the data and resources in the IT environment. A user entitlement review helps to ensure that the users have the appropriate and necessary access to perform their roles and functions, and to prevent or detect any unauthorized or inappropriate access. A data owner is the person or entity that has the authority and responsibility to define, classify, and protect the data and resources in the IT environment. A data owner helps to perform user entitlement reviews, because they help to establish and enforce the access policies and standards for the data and resources, and to approve or revoke the access requests and changes for the users. A data owner also helps to monitor and report on the access performance and compliance for the data and resources, and to identify and address any issues or gaps in the access management activities. The other options are not the primary responsible party for performing user entitlement reviews, although they may be involved in the process. IT security manager, IT personnel, and data custodian are all examples of roles or functions that can help to support or implement the user entitlement reviews, but they do not necessarily have the authority or responsibility to define, classify, or protect the data and resources. References = Risk and Information Systems Control Study Manual, Chapter 5, Section 5.2.1, page 5-14.

 A recovery time objective (RTO) is the maximum acceptable time that a business process or function can be disrupted or unavailable before it causes significant damage or loss to the organization. A business continuity plan (BCP) is a document that describes how the organization will resume its critical business operations in the event of a disaster or disruption. A disaster recovery plan (DRP) is a document that describes how the organization will restore its IT systems and infrastructure in the event of a disaster or disruption. The RTO defined in the BCP and the DRP should be consistent and aligned, as they both support the continuity and recovery of the business. If the RTO defined in the BCP is shorter than the RTO defined in the DRP, it means that the BCP expects the business process or function to be restored faster than the DRP can provide. This can create a gap or a conflict between the BCP and the DRP, and can compromise the effectiveness and efficiency of the continuity and recovery efforts. Therefore, the best way for the risk practitioner to address this concern is to communicate the discrepancy to the DR manager for follow-up, meaning that the risk practitioner should report the issue and its implications to the DR manager, who is responsible for developing and maintaining the DRP. The DR manager should review the discrepancy and determine whether it is justified or not, and whether it requires any adjustment or alignment of the RTOs in the BCP and the DRP. References = Risk and Information Systems Control Study Manual, Chapter 4, Section 4.4.2, p. 206-207

The best way to mitigate the high cost of retrieving electronic evidence associated with potential litigation is to implement policies and procedures for data retention and destruction. Data retention and destruction policies and procedures define the criteria, methods, and schedules for retaining and disposing of electronic data. They help to ensure that the electronic data is stored, managed, and deleted in a consistent, secure, and compliant manner. They also help to reduce the volume, complexity, and cost of retrieving electronic evidence, as they limit the scope, duration, and frequency of the data preservation and discovery process. The other options are not as effective as data retention and destruction policies and procedures, as they are related to the collection, analysis, or classification of electronic data, not the retention or destruction of electronic data. References = Risk and Information Systems Control Study Manual, Chapter 3: IT Risk Response, Section 3.3: IT Risk Response Implementation, page 145.
