Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Upgrade all users to Microsoft 365 Business Standard
Business Standard includes desktop apps but only provides 50 GB mailboxes, so it does not meet the 100 GB requirement.
B
Distractor review
Upgrade all users to Microsoft 365 Business Premium
Business Premium includes desktop apps and advanced security features but still only provides 50 GB mailboxes, failing the 100 GB requirement.
C
Distractor review
Keep Business Basic and purchase Exchange Online Plan 2 add-on for each user
This option does not provide the required desktop Office apps because Business Basic lacks them.
D
Best answer
Upgrade to Microsoft 365 E3
Microsoft 365 E3 includes desktop versions of Office apps and provides a 100 GB mailbox per user, satisfying both requirements with a single license.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this MS-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Upgrade to Microsoft 365 E3 — Microsoft 365 Business Basic does not include desktop Office apps and provides 50 GB mailboxes. Desktop apps are included in Business Standard and higher. To get 100 GB mailboxes, an Exchange Online Plan 2 add-on can be added to Business Standard, but that requires an additional license. Alternatively, Microsoft 365 E3 includes both desktop apps and 100 GB mailboxes, making it a single license that meets both requirements. For 500 users, E3 is more cost-effective than purchasing Business Standard plus Exchange Online Plan 2 add-ons.
