Answer is A, but Traffic Manager is not layer 7 load balancer. https://docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/load-balancing-overview

The most important point to understand is that Traffic Manager works at the DNS level which is at the Application layer (Layer-7). https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-how-it-works

Nope DNS returns an IP address, which is layer 3, see https://www.cohesive.net/blog/4-things-everyone-should-know-about-network-layers/. Layer 7, the application layer refers to the http or https app protocol.

Yes it is. https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-overview Azure Traffic Manager is a DNS-based traffic load balancer. This service allows you to distribute traffic to your public facing applications across the global Azure regions.

Layer 7 is application... If TM was a L7 appliance it would be able to do SSL offload, TLS termination, cookie-based session afinity, etc. That's why they refer to it as a L7 appliance, but only as DNS-based.

I agree, only Traffic Manager + Application Gateway or Front Door alone is layer 7 solution. https://portal.azure.com/#view/Microsoft_Azure_Network/LoadBalancingHubMenuBlade/~/overview

Selected Answer: A
A. Yes. This solution meets the goal. By deploying two Azure virtual machines in two separate Azure regions, you provide redundancy if one of the regions fails. Azure Traffic Manager can be used to distribute traffic between the virtual machines in different regions, ensuring high availability. Additionally, deploying Azure virtual machines allows you to have access to the full .NET Framework and grants administrators the ability to access the operating system to install custom application dependencies.

DNS-based load balancing operates at the network layer (layer 3), while layer 7 load balancing operates at the application layer

The traffic manager is DNS-based; and has health checks with HTTP(S) but is not level 7. I find the question rather ambiguous because it doesn't mention that you need to configure the health check and give access to the user.
