Security Fundamentals — Question 34

How does the sender policy framework (SPF) aim to reduce spoofed email?

Answer options

• A. It provides a list of IP address ranges for particular domains so senders can be verified.
• B. It includes an XML policy file with each email that confirms the validity of the message.
• C. It lists servers that may legitimately forward mail for a particular domain.
• D. It provides an encryption key so that authenticity of an email message can be validated

Correct answer: A

Explanation

The correct answer, A, is accurate because SPF works by specifying which IP addresses are authorized to send emails on behalf of a domain. The other options do not describe SPF's function; B refers to XML policies that are not part of SPF, C describes a related but different concept of mail forwarding, and D discusses encryption which is not a feature of SPF.
