Which of the following is a critical factor for implementing a successful data classification program?

The critical factor for implementing a successful data classification program is executive sponsorship. Executive sponsorship is the support and commitment from the senior management of the organization for the data classification program. Executive sponsorship can provide the necessary resources, authority, and guidance for the data classification program, and ensure that the program aligns with the organization’s goals, policies, and culture. Executive sponsorship can also influence and motivate the data owners, custodians, and users to participate and comply with the data classification program. The other options are not as critical as executive sponsorship, as they either do not have the same level of influence or authority (B, C, and D), or do not directly contribute to the data classification program (D). References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 2, page 66; Official (ISC)2 CISSP CBK Reference, Fifth Edition, Chapter 2, page 72.
