Exam AZ-104 topic 2 question 23 discussion

YES YES NO

No because VM2NI is not connected to VNET1 Yes No

1. No - because it's not stated the VM2-NI is connected to the VNET1 in the description - the question is can they both connect to VNET1 - so you don't know for VM2-NI 2. Yes - because the question embraces both the machines - and VM2 is spread over 2 zones, not being in the same DC. 3. No - being both machines in EastUS2 - when the region goes down - both of them sink too.

Answers: 1) VM1 and VM2 can connect to VNET1 = YES 2) If an Azure datacenter becomes unavailable, VM1 or VM2 will be available = YES 3) If the East US 2 region becomes unavailable, VM1 or VM2 will be available = NO Explanation: 1) Being in the same region booth VM's can connect to the same VNET. 2) VM1 and VM2 are in different Zones, so if a Datacenter becomes unavailable, either one or another will still be available. 3) Booth VM's are on the same Region, so if it goes down booth VM's will be down also.

Copilot Says: YES: VM1 and VM2 can connect to VNET1: Both VMs are connected to the virtual network VNET1. YES: If an Azure datacenter becomes unavailable, VM1 or VM2 will be available: Since VM1 and VM2 are in different availability zones, if one datacenter (zone) becomes unavailable, the other VM in a different zone will still be available. NO: If the East US 2 region becomes unavailable, VM1 or VM2 will be available: If the entire East US 2 region becomes unavailable, both VMs will be affected and will not be available. (Region Pair is not applicable because not mentioned on ARM template and should be setting up in advance)

correct

mmmh, the answer in this case is completely personal. I'll go for YYN, but the other side is NNN. I did some research, and based from this link: https://github.com/Azure/azure-quickstart-templates/blob/master/quickstarts/microsoft.network/vnet-2subnets-service-endpoints-storage-integration/azuredeploy.json effectively in the template is missing the part of the subnet related to vnic, so this one: "subnet": { "id": "[variables('subnetId')[copyIndex()]]" }, Altough is missing this one, so it should be NNN, is Microsoft really so a******e to do that? Idk. I'll go for YYN

Final Answer: Y Y N

For those who, like me, were struggling to understand why VM1 and VM2 can both connect to VNET1 despite having different NICs, see the excerpt below, and know that I tested this by creating a couple of VMs, each on their own networks, and was able to log into one and RDP into the other from it. "Each NIC attached to a VM must exist in the same location and subscription as the VM. Each NIC must be connected to a VNet that exists in the same Azure location and subscription as the NIC. " https://learn.microsoft.com/en-us/azure/virtual-network/network-overview

Correct

The answer to first question is in the first sentence - "You have an Azure subscription that contains a virtual network named VNET1 in the East US 2 region" - There is no other Vnet in East US 2, and both VMs are in same region, so, VM2-NI must be connected to VNET1. So, answer is Yes to first question.

1. NO - There is no mention that VM2 is deployed in VNET1 or that NIC2 is connected to VNET1 2. YES - If a datacenter will be unavailable, at least one on VM will be available since their are in different data centers a.k.a zones 3. NO - Both VMs are in same Region

YES, YES, NO https://learn.microsoft.com/en-us/azure/virtual-network/network-overview#virtual-machines

Nowhere it's mentioning VM2-NI is in VNET1.

N - "Can connect" vs "Can Be connected" two different things. Only VM1 "Can Connect to VNET1" Because it says it "VM1-NI" is connected to "VNET 1" Y - Because of zone: 1, zone:2 N - Both zones are in EastUS2

too many people overthink every single word in every single question...people chill

YYN VNET1 is in the same region as VM1 and VM2, so it can connect with both. "A resource can only be created in a virtual network that exists in the same region and subscription as the resource." https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-vnet-plan-design-arm#regions Passed the exam on 26 July 2023.
