Exam AZ-104 topic 13 question 1 discussion

I think this question is missing some critical info. Where does the VNET3 and 10.0.1.x/24 come from? No mentioning of them at all in the question!

I`ve passed the exam today with 900 and had this question. It was connected to testlet which has VNET1-4 and VM1-5. Few maybe helpful info: I got two case studies (testlests), each having 5 questions , one at the begining and one at the end (and in between 53 questions). As you can see there is a lot missing questions in testlets but some of those were the same as previous "normal" cut from the case study content - I got some with storage that I think I saw earlier. From the rest questions I got about 4-5 new ones.

where you guys see vnet3?

VNet1 peer with Vnet2 and vice versa vnet2 peer with vnet3 and vice versa. can you peer vnet3 back to vnet 1? :)

No info about Vnet3, but C and D are absolutly wrong, and NSG it is not necessary because not deny rules exists.

[Start Configuration] │ ▼ 1. Establish Peering between VNet1 and VNet3 │ ▼ 2. Enable Direct Connection between the two VNets │ ▼ 3. Send Traffic from VM1 to VM4 │ ▼ 4. VNet3 Receives Traffic and Forwards it to VM4 │ ▼ 5. VM4 Receives Traffic and Sends Response │ ▼ [Communication Complete]

B is right

B is right

Where is VNET3 in the description? Unable to answer then...

Correct answer: B: because we can not assign 10.0.1.5/24 to VM4, VM 4 is belong to VNET3 B: is best option

Just passed today 23-Apr-2023. All questions still in here. Thanks Examtopics

B. Establish peering between VNET1 and VNET3. Establishing VNet peering between VNET1 and VNET3 will allow VM1 to communicate with VM4 without the need for any additional configuration on the virtual machines themselves. VNet peering enables traffic to flow securely between virtual networks across Azure regions with low latency and high bandwidth. This approach minimizes administrative effort as there is no need to create or manage any additional network security groups or user-defined routes.

Has anybody considered that answer C is with or without context is already wrong by the wording? "Assign VM 4 an IP address of 10.0.1.5/24". A /24 is a subnet CIDR only if it would be a /32 this answer would be valid.

B. Establish peering between VNET1 and VNET3

B is the answer

B. Establish peering between VNET1 and VNET3. Establishing peering between the virtual networks (VNETs) allows traffic to flow between them without the need for additional configuration or routing. This solution minimizes administrative effort, as it requires only a single step to set up the peering. Option A, creating an NSG, would require additional rules and configuration to allow communication between VM1 and VM4. Option C, assigning a specific IP address to VM4, does not address the issue of network communication. Option D, creating a user-defined route, would also require additional configuration and management.

B is the answer. https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview Virtual network peering enables you to seamlessly connect two or more Virtual Networks in Azure. The virtual networks appear as one for connectivity purposes. The traffic between virtual machines in peered virtual networks uses the Microsoft backbone infrastructure. Like traffic between virtual machines in the same network, traffic is routed through Microsoft's private network only.
