Exam AZ-140 topic 1 question 14 discussion

In azure, never configure network settings inside the VM, always via the VNET or the NIC

The question requires a solution that keeps Azure Virtual Desktop operational even if a DNS server fails. Therefore, it would make sense to provide two DNS servers for redundancy, instead of relying on a single server. Also, to minimize administrative effort, it would be best to set these at the network level rather than individually on each virtual machine. Therefore, the correct answer should be: A. the DNS settings of VNET2 to use Server2 and Server1 This configuration allows the VMs in VNET2 to resolve both on-premises servers (through Server1) and Azure resources (through Server2). And if one DNS server fails, the other server can still handle the DNS requests, ensuring Azure Virtual Desktop remains operational. Also, setting the DNS servers at the VNET level simplifies management and reduces administrative effort.

A. the DNS settings of VNET2 to use Server2 and Server1 This configuration ensures that DNS resolution for both on-premises and Azure resources is handled by your existing DNS infrastructure, providing redundancy and minimizing administrative overhead. By setting the DNS settings at the VNET level, all virtual machines within VNET2 will automatically use these DNS servers, simplifying management.

At first, like everyone else, I selected A as the answer because the right thing to do is to add a DNS server in VNet2. However, the question never mentioned VNet2 with its own DNS server. Strictly going by on how the question was formulated, C is the correct answer. What do you think?

A. the DNS settings of VNET2 to use Server2 and Server1

The key is minimize administrative effort, should be A.

In azure, never configure network settings inside the VM

Minimize Effort.

Minimize administrative effort.

Given answer is too much work, A is correct

Answer is A You should configure the DNS settings of VNET2 to use Server2 and Server1 to meet the requirements. By configuring the DNS settings of VNET2 to use Server2 and Server1, the Azure Virtual Desktop users will be able to resolve on-premises servers and Azure resources. Since VNET2 is peered with VNET1 and has gateway transit enabled, the DNS servers in VNET1 will automatically be available in VNET2. This will ensure that Azure Virtual Desktop remains operational if a DNS server fails. Configuring the DNS settings at the VNET level will also minimize administrative effort, as you only need to make the change once instead of for each individual virtual machine.

Correct is A

Should be A because you never touch the VM Nic for such things

Configure via VNET to reduce administrative effort

Correct answer is A. I am using similar configuration in my organisation. You can setup it in a way desctribed in ansver C as well but you would have to do additional administration actions and it would be against requirement "Minimize administrative effort".

You should define DNS on VNet Level

In Azure you'll define DNS on vNET level
