ISO/IEC 24762:2008 - Information technology - Security techniques - Guidelines for information and communications technology disaster recovery services Free Practice Test — 30 Questions

Question 1

Considering the structured approach advocated by ISO/IEC 24762:2008 for restoring critical information and communications technology services following a significant disruption, which of the following best characterizes the initial phase of recovery operations?

Accepted Answer

A comprehensive restoration of all previously available services to their pre-disaster operational capacity.

Question 2

Consider a large financial institution that has recently experienced a significant disruption to its primary data center due to a severe cyberattack. The incident has rendered core trading platforms and customer account management systems inoperable. While the organization has a disaster recovery plan in place, the recovery process is proving to be significantly slower than anticipated, and the data loss exceeds the predefined recovery point objective. Analysis of the situation reveals that the initial risk assessment did not adequately consider the cascading effects of a sophisticated, multi-vector cyber threat, and the chosen recovery strategy, while cost-effective, lacked the necessary redundancy for such a high-impact scenario. Which fundamental aspect, as emphasized by ISO/IEC 24762:2008, was most likely underserviced, leading to the current suboptimal recovery outcome?

Accepted Answer

The meticulous development and validation of the disaster recovery plan, including comprehensive risk assessment and appropriate strategy selection.

Question 3

Considering the structured approach advocated by ISO/IEC 24762:2008 for restoring critical ICT services post-disruption, which of the following sequences best reflects the prioritized actions for achieving operational continuity and data integrity?

Accepted Answer

Restoration of core network infrastructure and essential communication channels, followed by the recovery of critical business applications and their associated data, and finally the re-establishment of less critical user services and peripheral systems.

Question 4

Consider an organization that has meticulously developed an ICT disaster recovery plan adhering to the principles outlined in ISO/IEC 24762:2008. This plan includes detailed procedures for data backup, system restoration, and network re-establishment, with clearly defined recovery point objectives (RPOs) and recovery time objectives (RTOs) for critical applications. However, during a simulated disaster exercise, it was observed that while the ICT systems were restored within their specified RTOs, several key business processes that relied on these systems were unable to resume operations effectively due to a lack of updated business process documentation and a shortage of trained personnel at the recovery site. Based on the guidance provided by ISO/IEC 24762:2008, what fundamental aspect of the disaster recovery strategy was likely underdeveloped, leading to this discrepancy?

Accepted Answer

The integration of ICT disaster recovery objectives with broader business continuity requirements and the validation of business process dependencies.

Question 5

Consider an enterprise that has meticulously developed a comprehensive disaster recovery (DR) plan aligned with ISO/IEC 24762:2008 guidelines, detailing the restoration of critical IT systems and data. However, this plan was formulated in isolation from the organization\'s broader business continuity planning (BCP) efforts. If a significant disruption occurs that impacts not only IT infrastructure but also the physical availability of key personnel and critical supply chains, what is the most likely consequence for the organization\'s overall resilience and ability to resume operations?

Accepted Answer

The disaster recovery plan will be insufficient to facilitate the resumption of essential business functions due to a lack of integration with non-IT-related business continuity strategies.

Question 6

Consider an organization that has developed a comprehensive Information and Communications Technology (ICT) Disaster Recovery Plan (DRP) in accordance with ISO/IEC 24762:2008. To ensure this ICT DRP effectively contributes to the organization\'s overall resilience and operational sustainability during and after a significant disruptive event, which broader management system framework would provide the most appropriate overarching structure for its integration and governance?

Question 18

Consider an enterprise where a recent business impact analysis (BIA) identified a core customer relationship management (CRM) system as a Tier 1 critical application. The BIA concluded that the business could tolerate a maximum of 2 hours of downtime for this system before significant customer dissatisfaction and potential loss of recurring revenue. Furthermore, the BIA indicated that a maximum of 1 hour of data loss would be acceptable for this CRM system. The IT department, however, has provisioned a disaster recovery solution for this CRM that guarantees a recovery time of 6 hours and a recovery point of 4 hours. What fundamental deficiency does this scenario highlight regarding the ICT disaster recovery services in relation to the organization\'s resilience strategy?

Accepted Answer

The defined Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for the CRM system are not aligned with the business's tolerance for disruption as determined by the Business Impact Analysis.
