What is the PRIMARY benefit of aligning information architecture with enterprise architecture (EA)?

While improved communication can be a byproduct of a well-aligned architecture, it is not the primary technical benefit of structurally linking data to business functions.

Ensuring data quality standards is an outcome of good data governance, which is supported by information architecture, but the core alignment benefit is understanding the data-to-business relationship and traceability.

Aligning information architecture with enterprise architecture allows an organization to map data flows and data elements directly to business capabilities, processes, and applications, enabling a clear understanding of how data supports and contributes to specific business functions.

Facilitating appropriate access is related to data security and governance, which information architecture supports by defining data classifications, but the primary alignment benefit is the visibility of data's role within business functions.
