Exam AZ-104 topic 5 question 42 discussion

Correct Answer: Box 1: vNET6 only Peering status to both VNet1 and Vnet2 are disconnected. So, only communication inside vNET6. Box 2: delete peering1 Peering to vNET1 is enabled but disconnected. We need to delete the peering from both virtual networks, and then re-create them. You can't add address ranges to or delete address ranges from a virtual network's address space once a virtual network is peered with another virtual network. To add or remove address ranges, delete the peering, add or remove the address ranges, then re-create the peering.

The Answer is correct. - Since both peerings are disconnected. then only communication inside VNet6 - It should be to create peerings on Vnet1 to enable. However, since it is an option here. Then the nearest one is to delete the peering also on Vnet6 then recreate again.

“Gateway transit” isn’t relevant to this question. Gateway transit applies to a hub‑and‑spoke design, whereas here the exam simply asks how to remove a disconnected peering and recreate it. In a hub‑and‑spoke scenario, the spoke VNet hosts application servers that send traffic to the hub VNet. A user‑defined route (UDR) points traffic from the spoke to an NVA (firewall) in the hub, and then the hub’s gateway (enabled via “Use remote gateways”) carries that traffic on to the on‑premises network.

I remember a similar question like this, might be it on 2nd test

Given answer is correct Box 1: vNET6 only it is default behavior Box 2: delete peering1 and redo it to establish connection state up

On exam 4/12/2022. answer correct

On the exam today, 4.March.2022

most dumb options for second question

Was on exam today 19.11.2021. Passed with 920. Correct answer: - VNET6 only - Delete peering 1

Box 1: vNET6 only is not correct imho. The NSG default rules allow communication in between the virtual networks within the same subscription and I just tested it so the last option (all vnets in the same subscription) is in my opinion the correct one.

Honestly, I didn't even notice that the peerings were disconnected because it seemed too easy.

"The peering status is "Disconnected" To resolve this issue, delete the peering from both virtual networks, and then re-create them." - https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-troubleshoot-peering-issues#the-peering-status-is-disconnected

Why they dont include the complete answer... delete and recreate the peering.

The provided answer is correct.
