This MD-102 practice question tests your understanding of manage applications. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Exhibit
Refer to the exhibit.

Refer to the exhibit. You are deploying Microsoft 365 Apps via Intune Win32 app packaging. The detection rule checks for the registry key existence. After installation, Intune reports the app as not detected. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The detection runs in 32-bit context and does not see the 64-bit registry key
Option C is correct. The registry path uses 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Common\InstallRoot' but on a 64-bit system, a 32-bit app (like the detection agent) may be redirected to WOW6432Node. The check32BitOn64System is false, so it does not check the WOW6432Node path. Option A is wrong because the path is correct on 64-bit systems for 64-bit Office. Option B is wrong because Office does install that key. Option D is wrong because the detection type 'exists' is correct.
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.
✗
The detection type 'exists' is not supported for registry detection
Why it's wrong here
'Exists' is a valid detection type.
✗
The registry key path is incorrect for a 64-bit system
Why it's wrong here
The path is correct for 64-bit Office.
✗
The app did not create the registry key during installation
Why it's wrong here
Office creates this key.
✓
The detection runs in 32-bit context and does not see the 64-bit registry key
Why this is correct
32-bit detection redirected to WOW6432Node, but check32BitOn64System is false.
Clue confirmation
The clue word "most likely" 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 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 is the correct answer to this question?
The correct answer is: The detection runs in 32-bit context and does not see the 64-bit registry key — Option C is correct. The registry path uses 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Common\InstallRoot' but on a 64-bit system, a 32-bit app (like the detection agent) may be redirected to WOW6432Node. The check32BitOn64System is false, so it does not check the WOW6432Node path. Option A is wrong because the path is correct on 64-bit systems for 64-bit Office. Option B is wrong because Office does install that key. Option D is wrong because the detection type 'exists' is correct.
