Exhibit

Inbound NSG rules on AppSubnet:
Priority 200  Deny-All-Inbound      Any      Any      Any      Any    Deny
Priority 250  Allow-HTTPS-Admin     TCP      203.0.113.20/32   Any   443    Allow
Priority 300  Allow-HTTPS-Internet  TCP      Internet          Any   443    Allow
Test source IP: 203.0.113.20
Observed result: TCP 443 denied

Based on the exhibit, HTTPS traffic from the admin workstation is still being blocked. What change should the administrator make?

Based on the exhibit, HTTPS traffic from the admin workstation is still being blocked. What change should the administrator make?

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

Delete the Deny-All-Inbound rule.

Removing the deny rule would open more traffic than intended and is not the least disruptive fix. The real problem is priority order, not the existence of a deny rule.

B

Best answer

Change Allow-HTTPS-Admin to priority 100.

NSG rules are evaluated from the lowest priority number to the highest. In the exhibit, the deny rule at priority 200 is matched before the allow rule at 250, so traffic is blocked. Moving the admin allow rule to a lower number such as 100 makes it evaluate first and permits the HTTPS test traffic.

C

Distractor review

Change Allow-HTTPS-Admin protocol from TCP to Any.

The traffic is already TCP 443, so changing the protocol to Any does not address the fact that the deny rule is evaluated first. Priority, not protocol, is the issue.

D

Distractor review

Move the allow rule to outbound traffic.

The connection attempt is inbound to the VM, so moving the rule to outbound would not allow the HTTPS session. The direction must match the traffic flow being filtered.

Common exam trap

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Technical deep dive

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

  • Standard ACLs match source addresses.
  • Extended ACLs can match source, destination, protocol and ports.
  • The first matching ACL entry is used.
  • There is usually an implicit deny at the end.

TExam Day Tips

  • Check inbound versus outbound direction.
  • Read the ACL from top to bottom.
  • Look for a broader permit or deny above the intended line.

FAQ

Questions learners often ask

What does this AZ-104 question test?

Standard ACLs match source addresses.

What is the correct answer to this question?

The correct answer is: Change Allow-HTTPS-Admin to priority 100. — The deny rule has a higher evaluation precedence because it uses a lower priority number than the allow rule. Since NSGs process rules from lowest number to highest, the packet matches Deny-All-Inbound at 200 before it reaches Allow-HTTPS-Admin at 250. Changing the allow rule to a smaller priority number, such as 100, makes it win first and permits only the intended admin source. Why others are wrong: Deleting the deny rule weakens security more than needed, changing protocol does not alter priority, and outbound rules do not control inbound access. The exhibit clearly shows a priority-order problem, so the fix must preserve the deny rule while ensuring the specific allow rule is evaluated earlier.
