AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You need to expose a web application running on several VMs and distribute traffic across them based on HTTP request attributes such as URL path. Which service should you use?
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
✓
Azure Application Gateway
Azure Application Gateway is a Layer 7 load balancer that can route traffic based on HTTP request attributes such as URL path, host headers, or query strings. This allows you to distribute incoming web traffic across multiple VMs based on the specific URL path (e.g., /images to one backend pool, /api to another), which is exactly what the question requires.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Load Balancer
Why it's wrong here
Load Balancer is primarily Layer 4 and does not do URL path routing.
When this WOULD be correct
When you need to distribute incoming network traffic across multiple VMs or virtual machine scale sets within a region for high availability, using only TCP/UDP protocols without inspecting HTTP content.
- ✓
Azure Application Gateway
Why this is correct
Application Gateway supports Layer 7 features including path-based routing.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Traffic Manager
When this WOULD be correct
You need to distribute traffic across multiple Azure regions based on endpoint health or performance, and you want to route users to the closest or most responsive region. Traffic Manager is the correct choice for global DNS-based traffic routing.
- ✗
Network Watcher
Why it's wrong here
Network Watcher is for diagnostics and monitoring, not application load balancing.
When this WOULD be correct
You need to monitor network performance, diagnose connectivity issues, or capture packet traces for a virtual network. For example, 'You need to identify a connectivity issue between two VMs in different subnets' would make Network Watcher correct.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Azure Application GatewayCorrect answer▾
Why this is correct
Application Gateway supports Layer 7 features including path-based routing.
✗Azure Load BalancerWrong answer — click to see why▾
Why this is wrong here
Azure Load Balancer operates at Layer 4 (transport layer) and distributes traffic based on IP address and port, not HTTP request attributes like URL path. It cannot perform content-based routing.
★ When this WOULD be the correct answer
When you need to distribute incoming network traffic across multiple VMs or virtual machine scale sets within a region for high availability, using only TCP/UDP protocols without inspecting HTTP content.
Why candidates choose this
Candidates may confuse load balancing at Layer 4 with Layer 7, assuming all load balancers can route based on HTTP attributes, or they may not be aware of the specific capabilities of Azure Application Gateway.
✗Traffic ManagerWrong answer — click to see why▾
Why this is wrong here
Traffic Manager operates at the DNS level, distributing traffic based on domain name resolution, not HTTP request attributes like URL path. It cannot inspect or route based on HTTP-level details.
★ When this WOULD be the correct answer
You need to distribute traffic across multiple Azure regions based on endpoint health or performance, and you want to route users to the closest or most responsive region. Traffic Manager is the correct choice for global DNS-based traffic routing.
Why candidates choose this
Candidates may confuse Traffic Manager with a load balancer that can handle HTTP traffic, but its DNS-level routing lacks the application-layer awareness needed for URL path-based distribution.
✗Network WatcherWrong answer — click to see why▾
Why this is wrong here
Network Watcher is a monitoring and diagnostics service for Azure networks, not a traffic distribution service. It cannot route or load balance HTTP traffic based on request attributes.
★ When this WOULD be the correct answer
You need to monitor network performance, diagnose connectivity issues, or capture packet traces for a virtual network. For example, 'You need to identify a connectivity issue between two VMs in different subnets' would make Network Watcher correct.
Why candidates choose this
Candidates may confuse Network Watcher with a network traffic management tool due to its name, or think it can handle traffic distribution because it deals with network-level operations.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Load Balancer (Layer 4) with Application Gateway (Layer 7), assuming any load balancer can route based on HTTP attributes, but only Application Gateway can inspect and route based on URL paths, host headers, or query strings.
Detailed technical explanation
How to think about this question
Azure Application Gateway uses a set of routing rules defined in its HTTP settings and listeners to match URL paths and route requests to appropriate backend pools. It supports features like URL-based routing, multi-site hosting, and Web Application Firewall (WAF) integration. Under the hood, it terminates the client SSL connection, inspects the HTTP request, and forwards the request to the backend based on the path map, which is a key differentiator from Layer 4 load balancers.
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.
