1. PCI Security Standards Council, "PCI Card Production and Provisioning - Logical Security Requirements, Version 3.0," November 2020.
Requirement A.2.1: "Educate personnel upon hire and at least annually." This establishes the annual frequency.
Requirement A.2.2: "Personnel are educated about procedures for recognizing and reporting potential security incidents." This directly supports that training must cover topics like common attack methods, which are the primary source of security incidents that personnel would need to recognize.
Requirement A.2.1 (Note): "Multiple methods of communication must be used to ensure personnel are educated (for example, posters, letters, memos, web-based training, meetings, and promotions)." This shows that posters (Option D) are an example, not a mandate.
Requirement A.2.1: "Personnel must acknowledge, in writing or electronically, that they have read and understood the information security policy at least annually." This specifies acknowledgment, not an exam (Option C).
