- A
Change the protocol from TCP to Any on the allow rule.
Why wrong: The protocol already matches the traffic type in the scenario. Broadening protocol alone will not help if the deny rule is still evaluated first.
- B
Move the Allow-HTTPS-Admin rule to a priority number lower than 200.
NSG rules are processed in priority order, and the lowest number wins. Because Deny-All-Inbound is at priority 200, it is evaluated before the allow rule at 250 and blocks the traffic. Moving the allow rule to a smaller number than 200 lets the admin workstation's HTTPS traffic match the allow rule first.
- C
Associate a NAT gateway with the subnet.
Why wrong: A NAT gateway affects outbound source translation. It does not change inbound NSG evaluation or permit management access to a subnet.
- D
Enable service endpoint policies on the subnet.
Why wrong: Service endpoint policies control Azure PaaS access over service endpoints. They are not used to permit inbound HTTPS to a VM.
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An NSG attached to a subnet contains these inbound rules: Deny-All-Inbound at priority 200, Allow-HTTPS-Admin at priority 250 from 203.0.113.20/32, and Allow-HTTPS-Internet at priority 300. A VM in the subnet cannot receive HTTPS from the admin workstation even though the source IP is correct. What should the administrator change?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Move the Allow-HTTPS-Admin rule to a priority number lower than 200.
The Deny-All-Inbound rule at priority 200 blocks all traffic, including HTTPS from the admin workstation, because NSG rules are evaluated in priority order (lowest number first). The Allow-HTTPS-Admin rule at priority 250 is never reached since the deny rule with a higher priority (lower number) matches first. To allow the admin traffic, the allow rule must have a priority lower than 200 (e.g., 150) so it is evaluated before the deny rule.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Change the protocol from TCP to Any on the allow rule.
Why it's wrong here
The protocol already matches the traffic type in the scenario. Broadening protocol alone will not help if the deny rule is still evaluated first.
- ✓
Move the Allow-HTTPS-Admin rule to a priority number lower than 200.
Why this is correct
NSG rules are processed in priority order, and the lowest number wins. Because Deny-All-Inbound is at priority 200, it is evaluated before the allow rule at 250 and blocks the traffic. Moving the allow rule to a smaller number than 200 lets the admin workstation's HTTPS traffic match the allow rule first.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a higher priority number means higher precedence, but in Azure NSGs, a lower numeric priority value (e.g., 200) is evaluated before a higher one (e.g., 250), so the deny rule blocks the traffic before the allow rule is checked.
Trap categories for this question
Scenario analysis trap
The protocol already matches the traffic type in the scenario. Broadening protocol alone will not help if the deny rule is still evaluated first.
Detailed technical explanation
How to think about this question
NSGs use a priority system where rules are evaluated from lowest to highest numeric value; once a rule matches, no further rules are processed. The Deny-All-Inbound rule at priority 200 matches all traffic before the allow rule at priority 250 is evaluated, effectively making the allow rule dead. In real-world scenarios, administrators often mistakenly place a broad deny rule at a high priority (low number) without realizing it will override all lower-priority allow rules, leading to connectivity failures that are resolved by reordering rule priorities.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
