The correct answer is that this session policy blocks downloads of files from SharePoint Online and OneDrive for Business on unmanaged devices. This is because the policy specifically targets the “Block download” action for both SharePoint and OneDrive when accessed from either browsers or native clients, and it applies only to devices not marked as compliant or managed. On the MS-102 exam, this scenario tests your understanding of how Conditional Access session controls integrate with app-enforced restrictions to protect data on unmanaged devices—a common trap is confusing “block download” with “block upload” or assuming it only applies to browsers. Remember the key distinction: the policy prevents data exfiltration via download, not collaboration via upload, and it covers all access methods. A helpful memory tip is “D.U.B.”—Downloads on Unmanaged devices are Blocked.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Blocks download of files from SharePoint Online and OneDrive on unmanaged devices
Option B is correct because the policy blocks download actions for SharePoint Online and OneDrive for Business when accessed from browsers or native clients on unmanaged devices. Option A is wrong because it blocks download, not upload. Option C is wrong because it applies to both browsers and native clients. Option D is wrong because it blocks downloads, not view.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Allows viewing but blocks downloading files on managed devices
Why it's wrong here
It blocks download on unmanaged devices, not managed.
✗
Blocks all access to SharePoint and OneDrive from unmanaged native clients only
Why it's wrong here
It blocks download, not all access, and applies to both browsers and native clients.
✗
Blocks upload of files to SharePoint Online and OneDrive from unmanaged devices
Why it's wrong here
The action is block download, not upload.
✓
Blocks download of files from SharePoint Online and OneDrive on unmanaged devices
Why this is correct
The policy blocks download actions.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
