Typical locations where card verification values/code may be found include which of the following?

The correct answer identifies that databases and log files from e-commerce systems are typical locations where card verification values (CVVs) or codes may be found. In e-commerce systems, transactions often involve the storage and processing of sensitive card information for various purposes such as order processing, fraud detection, or customer support.

Databases used in e-commerce often log transaction details, including payment information, which may sometimes include CVVs if not handled correctly. It is vital for businesses to adhere to PCI DSS (Payment Card Industry Data Security Standard) regulations, which specify how this sensitive information should be stored, processed, and transmitted to ensure the security and privacy of customers.

In contrast, other answer choices involve locations that are not typical for CVVs to be found due to security practices or their nature. For instance, email accounts are generally not considered secure storage for such sensitive information. Web cache files may temporarily store data but are not reliable or secure for sensitive information storage. Customer interaction records, while valuable in understanding customer behavior, typically do not store CVVs as a best practice for security and compliance reasons.
