Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SPF
Why it's wrong here
SPF only specifies which servers are authorized to send email for a domain, but does not provide a policy for handling failures.
- ✗
DKIM
Why it's wrong here
DKIM adds a digital signature, but does not specify handling of failures.
- ✗
SenderBase
Why it's wrong here
SenderBase is a reputation system, not an email authentication method.
- ✓
DMARC
Why this is correct
DMARC uses SPF and DKIM results and tells receivers how to handle unauthenticated email (e.g., quarantine or reject).
