The answer is to enable delivery optimization and set the Office update channel to Current Channel. This configuration minimizes bandwidth for Microsoft 365 Apps updates by leveraging peer-to-peer distribution, allowing devices on your local network to share update bits rather than each device downloading them individually from the Office Content Delivery Network (CDN). On the MD-102 exam, this scenario tests your understanding of how to balance update delivery speed with network efficiency, often appearing as a trap where candidates mistakenly choose BranchCache or assume the CDN alone is sufficient. Remember, delivery optimization is the Intune-native method for peer-to-peer caching of Office updates, while BranchCache is designed for file server content, not Office CDN traffic. A simple memory tip: “Peer-to-peer saves the peer-to-CDN bandwidth.”
MD-102 Prepare infrastructure for devices Practice Question
This MD-102 practice question tests your understanding of prepare infrastructure for devices. 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.
You are responsible for deploying Microsoft 365 Apps for enterprise to Windows 10 devices using Microsoft Intune. You want to ensure that users receive the Current Channel with updates delivered directly from the Office Content Delivery Network (CDN). You also want to minimize bandwidth usage on your network. What should you configure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable delivery optimization and set the Office update channel to Current Channel.
To minimize bandwidth, you can enable peer-to-peer distribution and configure delivery optimization. Option C is correct because enabling delivery optimization with peer-to-peer reduces network load. Option A is wrong because CDN is the default but does not minimize bandwidth. Option B is wrong because BranchCache is not used for Office updates. Option D is wrong because peer-to-peer is the recommended approach.
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.
✗
Configure a local update server using BranchCache.
Why it's wrong here
BranchCache is for file servers, not Office updates.
✗
Set the update path to the Office CDN and enable Office automatic updates.
Why it's wrong here
This does not minimize bandwidth usage.
✗
Use a configuration profile to disable peer-to-peer distribution.
Why it's wrong here
Disabling peer-to-peer increases bandwidth usage.
✓
Enable delivery optimization and set the Office update channel to Current Channel.
Why this is correct
Delivery optimization with peer-to-peer reduces bandwidth.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
