Quick Answer
The answer is spoof intelligence, mailbox intelligence, and user impersonation protection. These three settings are core components of an anti-phish policy in Microsoft Defender for Office 365 because they directly target the most common phishing vectors: forged sender addresses, compromised mailboxes, and impersonated executives or domains. On the Microsoft 365 Administrator MS-102 exam, this question tests your ability to distinguish between policy-level protections and infrastructure-level configurations; a common trap is confusing DKIM, which is a DNS-based email authentication method, with anti-phish policy settings, or selecting Safe Attachments, which is a separate policy for scanning email attachments. Remember that anti-phish policies focus on who the email appears to come from, not what it contains. A useful memory tip is the acronym SIM: Spoof intelligence, Impersonation protection, and Mailbox intelligence—these are the three pillars you configure directly inside the anti-phish policy blade.
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE settings can you configure in a Microsoft Defender for Office 365 anti-phish policy?
Mailbox intelligence
Mailbox intelligence is part of anti-phish policies.
Safe Attachments
Why wrong: Safe Attachments is a separate policy type.
DKIM signing
Why wrong: DKIM is configured at the domain level, not in anti-phish policy.
User impersonation protection
User impersonation protection is configured in anti-phish policies.
Spoof intelligence
Spoof intelligence is configured in anti-phish policies.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Mailbox intelligence
Options B, C, and D are correct. Anti-phish policies include spoof intelligence, mailbox intelligence, and user impersonation protection. Option A is wrong because DKIM is configured in the domain's DNS. Option E is wrong because Safe Attachments is a separate policy.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Mailbox intelligence
Why this is correct
Mailbox intelligence is part of anti-phish policies.
Related concept
Static NAT maps one inside address to one outside address.
Safe Attachments
Why it's wrong here
Safe Attachments is a separate policy type.
DKIM signing
Why it's wrong here
DKIM is configured at the domain level, not in anti-phish policy.
User impersonation protection
Why this is correct
User impersonation protection is configured in anti-phish policies.
Related concept
Static NAT maps one inside address to one outside address.
Spoof intelligence
Why this is correct
Spoof intelligence is configured in anti-phish policies.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MS-102 NAT questions on configuration and troubleshooting.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are configuring Microsoft Defender for Office 365 anti-phish policy. You want to protect against user impersonation attacks. The CEO and CFO are frequent targets. What should you configure in the anti-phish policy?
hardWhy C: Option B is correct because user impersonation protection allows you to define specific users to protect. Option A is wrong because domain impersonation protects against domain spoofing. Option C is wrong because mailbox intelligence is for general impersonation detection. Option D is wrong because spoof intelligence is for domain spoofing.
