Which of the following is the BEST indication that information security requirements are taken into consideration when developing IT processes?

Deploying a database in a distributed processing platform is an architectural choice for performance or scalability, not directly indicative of specific information security requirements being considered.

When the information architecture incorporates data classification, it signifies that information security requirements have been fundamentally considered at the design stage of IT processes. Data classification is the foundation for applying appropriate security controls based on the sensitivity and criticality of information, directly indicating that security has been embedded into how data is structured and managed.

Storing customer profiles with a domestic service provider might address data residency or compliance concerns, but it doesn't indicate a comprehensive approach to integrating security requirements into IT processes.

Periodically reviewing the integrity of sensitive information is an operational security control or audit activity, which occurs after processes are developed, rather than indicating that security was considered during their development.
