Which of the following is NOT one of the principal parts of the privacy requirements outlined in the GLB Act?

The correct answer is the Consumer Trust Rule, as it is not one of the principal parts of the privacy requirements established by the Gramm-Leach-Bliley Act (GLB Act). The GLB Act primarily focuses on the protection of consumers' personal financial information and consists of three key components: the Financial Privacy Rule, which governs how financial institutions must handle nonpublic personal information; the Safeguards Rule, which outlines the measures that must be implemented to protect personal information; and the Pretexting provisions, which are designed to prevent unauthorized access to personal information through deceitful means.

Understanding the GLB Act and its requirements is crucial for anyone working within the financial services industry, as it establishes the standard for privacy practices and consumer rights regarding financial data. The absence of a rule specifically labeled as the Consumer Trust Rule emphasizes the need to correctly identify and understand the existing provisions that do focus on privacy and security in handling consumer financial information.
