WordPress Professional Standards & Competencies 4

Question 1

A client wants to store their customers' credit card numbers in a custom WordPress database table. What is the professional response?

Accepted Answer

Advise against it and recommend PCI-compliant payment processors like Stripe or PayPal

Answer

Storing raw card data violates PCI DSS; professionals must redirect clients to compliant payment processors instead.

Question 2

What is the professional rationale for using child themes instead of modifying a parent theme directly?

Accepted Answer

Modifications to a parent theme are lost when the theme is updated

Answer

Parent theme updates overwrite customizations; child themes preserve modifications across updates.

Question 3

Which is the correct professional approach to handling a client's GDPR data deletion request on their WordPress site?

Answer

GDPR requires complete erasure of all PII across every data store, not just partial deletion from one location.

Question 4

How should a professional WordPress developer handle a disagreement with a client about a technical approach?
