Which two statements about network security group processing are correct? Select two.
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
Best answer
NSG rules are evaluated starting with the lowest priority number.
Correct because Azure processes NSG rules in ascending priority order, so smaller numbers are checked first.
B
Distractor review
An NSG can be linked only to a subnet, not to a network interface card.
False because an NSG can be associated with either a subnet or an individual network interface.
C
Best answer
A deny rule with a lower number can block traffic even if an allow rule exists later.
Correct because the first matching rule wins, so an earlier deny stops evaluation for that traffic.
D
Distractor review
Azure ignores NSG rules whenever a route table is attached to the subnet.
False because routing and security are separate functions. A route table does not disable NSG evaluation.
E
Distractor review
Security rules are processed alphabetically by name.
False because NSG processing uses numeric priority, not the rule name or alphabetical order.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

Question 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: NSG rules are evaluated starting with the lowest priority number. — Azure evaluates NSG rules by priority, beginning with the lowest number. This means a deny rule can stop matching traffic before a later allow rule is reached. NSGs can also be associated with either a subnet or a network interface, which gives administrators flexibility in where they apply the control. Understanding these two ideas helps explain many day-to-day access issues. Why others are wrong: The wrong choices describe rule names, route tables, or an association model that is too limited. NSGs are not ordered alphabetically, and route tables do not turn off security evaluation. The association scope is broader than one subnet because Azure also supports NIC-level NSGs for more targeted control.
