Which of the following issues found during the review of a newly created disaster recovery plan (DRP) should be of MOST concern?

If critical business applications are excluded from the disaster recovery plan, the organization will be fundamentally unable to resume its essential functions post-disruption, rendering the DRP ineffective for core business continuity and leading to severe operational and financial consequences.

Outsourcing recovery activities is a common and acceptable practice, provided that appropriate service level agreements (SLAs) and oversight are in place to ensure effectiveness.

While adhering to an internationally recognized framework is beneficial for structuring and comprehensive coverage, a DRP can still be technically sound and effective if it addresses the organization's specific needs, even without strict framework adherence.

CISO approval is vital for governance and endorsement, but the absence of this approval does not inherently compromise the technical viability or the content of the recovery plan itself as much as missing critical components.
