- A
Change the allow rule priority to a number lower than 200.
NSG rules are evaluated in ascending priority order, so the lower number is processed first. Because Deny-All-Inbound at 200 is taking effect before the allow rule at 250, the connection is blocked. Moving the allow rule to a priority such as 150 ensures the specific HTTPS exception is matched before the broad deny rule.
- B
Change the deny rule priority to 65000 so it is evaluated first.
Why wrong: A higher numeric priority is evaluated later, not earlier, so this would not fix the problem correctly.
- C
Convert the allow rule to an outbound rule instead of inbound.
Why wrong: The issue is inbound access to the VM, so an outbound rule would not affect the connection attempt.
- D
Replace the NSG with a route table so HTTPS can pass through the subnet.
Why wrong: Route tables affect next-hop selection, not packet अनुमति decisions for inbound traffic.
Quick Answer
The answer is to change the allow rule priority to a number lower than 200. This is because Azure NSG rule priority follows a strict ascending order, where lower numbers are evaluated first and higher numbers are processed later. Since the Deny-All-Inbound rule has priority 200, it is evaluated before the Allow-Admin-HTTPS rule at priority 250, meaning the deny rule matches and blocks all inbound traffic, including the HTTPS connection from the allowed IP, before the allow rule ever gets a chance to permit it. On the AZ-104 exam, this scenario tests your understanding of NSG rule priority order and the common trap of assuming a higher-priority allow rule can override a lower-priority deny rule—it cannot, because processing stops at the first match. A helpful memory tip is to think of NSG priorities like a race: the smallest number wins the first evaluation, so your allow rule must sprint ahead of any deny rule to let traffic through.
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 administrator added an NSG rule named Allow-Admin-HTTPS with priority 250 to permit inbound TCP 443 from a single public IP. The NSG also contains a Deny-All-Inbound rule with priority 200. The administrator still cannot connect to the VM over HTTPS from the allowed IP. What should be changed to resolve the issue?
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
Change the allow rule priority to a number lower than 200.
The Deny-All-Inbound rule with priority 200 is evaluated before the Allow-Admin-HTTPS rule with priority 250 because NSG rules are processed in order of ascending priority (lower numbers are evaluated first). Since the deny rule matches all inbound traffic, it blocks the HTTPS connection before the allow rule can be evaluated. To resolve this, the allow rule must have a priority lower than 200 (e.g., 150) so it is evaluated first and permits the traffic from the specified public IP.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
NSG rules are evaluated in ascending priority order, so the lower number is processed first. Because Deny-All-Inbound at 200 is taking effect before the allow rule at 250, the connection is blocked. Moving the allow rule to a priority such as 150 ensures the specific HTTPS exception is matched before the broad deny rule.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume higher priority numbers mean higher precedence, but in Azure NSGs, lower priority numbers are evaluated first, so a deny rule with a lower number will block traffic before a higher-numbered allow rule can permit it.
Detailed technical explanation
How to think about this question
Azure NSGs evaluate rules in priority order, from lowest to highest number, and stop processing once a matching rule is found (the first match wins). The default DenyAllInbound rule has priority 65000, but custom deny rules at lower priorities can override allows. In this scenario, the deny rule at 200 matches all inbound traffic, so the allow rule at 250 is never reached. A common real-world scenario is when an administrator adds a high-priority deny rule for security but forgets to place critical allow rules at even lower priorities, causing connectivity failures.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

What is the correct answer to this question?
The correct answer is: Change the allow rule priority to a number lower than 200. — The Deny-All-Inbound rule with priority 200 is evaluated before the Allow-Admin-HTTPS rule with priority 250 because NSG rules are processed in order of ascending priority (lower numbers are evaluated first). Since the deny rule matches all inbound traffic, it blocks the HTTPS connection before the allow rule can be evaluated. To resolve this, the allow rule must have a priority lower than 200 (e.g., 150) so it is evaluated first and permits the traffic from the specified public IP.
