Exam AZ-104 topic 2 question 26 discussion

Actual exam question from Microsoft's AZ-104
Question #: 26
Topic #: 2
[All AZ-104 Questions]

You have an Azure subscription.
Users access the resources in the subscription from either home or from customer sites. From home, users must establish a point-to-site VPN to access the Azure resources. The users on the customer sites access the Azure resources by using site-to-site VPNs.
You have a line-of-business-app named App1 that runs on several Azure virtual machine. The virtual machines run Windows Server 2016.
You need to ensure that the connections to App1 are spread across all the virtual machines.
What are two possible Azure services that you can use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

  • A. an internal load balancer
  • B. a public load balancer
  • C. an Azure Content Delivery Network (CDN)
  • D. Traffic Manager
  • E. an Azure Application Gateway
Show Suggested Answer Hide Answer
Suggested Answer: AE 🗳️
Network traffic from the VPN gateway is routed to the cloud application through an internal load balancer. The load balancer is located in the front-end subnet of the application.

Correct Answer: A and E A: The customer sites are connected through VPNs, so an internal load balancer is enough. B: The customer sites are connected through VPNs, so there's no need for a public load balancer, an internal load balancer is enough. C: A CDN does not provide load balancing for applications, so it not relevant for this situation. D: Traffic manager is a DNS based solution to direct users' requests to the nearest (typically) instance and does not provide load balancing for this situation. E: Azure Application Gateway is a valid option, as it provides load balancing in addition to routing and security functions

A: what do you mean by "internal LB is enough"?

It means that nobody is accessing the resources through public ip ..So no need of a public load balancer.

But isn't answer B also an option which would suffice the requirements? It only states to load balance traffic to all VMs. It does not restrict how to access the services, even though we are already connected via vpn...

I'd say you are right. But they ask only for two answers and this would not be preferred solution.

VMs are internal and users connect through S2S and P2S VPN. you do not want to expose your internal workloads to the internet using public LB

I used free version access for this site and it helped me pass the exam. Some questions that I had on the exams, I took the exam more than once, are not available under the free tier access, but 80% of the questions came from here. I do recommend investing a bit of money and getting full access to this site. I didn't memorise answers but analysed them and studied as Microsoft does tweak them a bit. This Q was on the exam and the answer isA, E.

Two possible Azure services that can be used to spread connections to App1 across all virtual machines are: A. an internal load balancer: An internal load balancer can be used to distribute traffic among the virtual machines running App1. It can distribute traffic based on various algorithms such as round-robin, least connections, and IP hash. The internal load balancer is a layer 4 (Transport Layer) load balancer that can distribute traffic within a virtual network. E. an Azure Application Gateway: An Azure Application Gateway is a layer 7 (Application Layer) load balancer that can distribute traffic based on various criteria such as URL path, host headers, and cookie. It can also perform SSL offloading, session affinity, and URL-based routing. It is typically used to route traffic to different backend services based on the incoming request's contents. It is a more advanced option than the internal load balancer but requires a public IP address.

Two possible Azure services that can be used to spread connections to App1 across all virtual machines are: A. An internal load balancer: This service can be used to distribute network traffic to virtual machines that are part of an availability set or a virtual machine scale set. It works by forwarding incoming traffic to healthy virtual machines in the backend pool. Since App1 runs on multiple virtual machines, an internal load balancer can be used to distribute the traffic evenly among them. E. An Azure Application Gateway: This service is a layer 7 load balancer that can distribute traffic based on different criteria, such as URL path or host header. It can also perform SSL offloading, web application firewall, and other features that can enhance the performance and security of web applications. Since App1 is a line-of-business app, it's likely that it runs over HTTP or HTTPS, which makes an Azure Application Gateway a suitable solution for load balancing.
