AZ-103 Exam - Question 104

Question

You have the Azure virtual networks shown in the following table. To which virtual networks can you establish a peering connection from VNet1?

Examice · Accepted Answer

You cannot establish a peering connection between virtual networks that have overlapping address spaces. VNet1 (10.11.0.0/16) and VNet2 (10.11.0.0/17) have overlapping address spaces, so they cannot be peered. VNet3 (10.10.0.0/22) and VNet4 (192.168.16.0/22) do not have overlapping address spaces with VNet1 and can be peered with VNet1. Therefore, the correct answer is that you can establish a peering connection from VNet1 to VNet3 and VNet4 only.

msftfan · Answer

C. VNet3 and VNet4 only

DeadHead · Answer

Vnet1 and Vnet2 IPs are overlapping.

ExamPrep · Answer

Agreed - has to be C as VNet1 and VNet2 overlap with both the address space and subnets.

See here: https://www.microsoftpressstore.com/articles/article.aspx?p=2873369

"The address space is the most critical configuration for a VNet in Azure. This is the IP range for the entire network that will be divided into subnets. The address space can almost be any IP range that you wish (public or private). You can add multiple address spaces to a VNet. To ensure this VNet can be connected to other networks, the address space should never overlap with any other networks in your environment. If a VNet has an address space that overlaps with another Azure VNet or on-premises network, the networks cannot be connected, as the routing of traffic will not work properly."

Oooo · Answer

the correct answer is C - only vnet3 and vnet4. I was quite certain about it as the Addresses are overlapping but i checked on multiple sites and everywhere the answer was all the three vnets so i tried it myself to just clear it. i Could not do the peering so for sure the answer is vnet3 and vnet 4 only. Cheers.

RalphBR · Answer

It cannot connect to vnet2! Region has nothing to do but the IPs are overlapping so in the portal u wont even see vnet2 while creating ur vnet peering.

jt2214 · Answer

it has to be C.

Basheer · Answer

i did practically.
vnet3 an vnet4 is correct.
vnet1 and vnet2 are overlaping

deepu1207 · Answer

they are located at differeent region is it possible to peering for all zones

Nhan · Answer

The given answer is correct, you can peer all other Vnet to Vnet1, peering has nothign to do with region/physicall location.

Cloudyuga · Answer

Correct answer is C.
Because Vnet1 address space overlap with Vnet2.

dearram6655 · Answer

tested it is not working with Vnet2 so Vnet3 and Vnet4 is the correct answer

Can I peer two VNets with matching or overlapping address ranges?
No. Address spaces must not overlap to enable VNet Peering.

Meedeh · Answer

Answer to the question is C.

You can't create VNET peering to virtual networks in the same region. However, VNET3 and VNET4 belong to different regions which makes it ideal to connect.

PradyBear · Answer

I created vnet with exact same config and when tried to peer vnet1 and vnet2 then i could see azure says it cannot be peered .
Hence answer is C

anon1234 · Answer

First thoughts D because global peering

Then i read https://azure.microsoft.com/en-gb/updates/global-vnet-peering-general-availability/

North Europe not available to peer across regions

Now think C

[Removed] · Answer

It would be vnet3 and vnet4.....since vnet2 is overlapping address space..

nfett · Answer

its a trick question. if you look at the subnetting. B will go into A. thus the answer is C. VNet3 and VNet4 only.

eburgo · Answer

C should be correct, check this out https://github.com/Azure/acs-engine/issues/3139

tanito83 · Answer

The answer is C. Please modify it.

chan4u · Answer

Answer should be C.

clouddba · Answer

Answer:
C. VNet3 and VNet4 only

kaviraj · Answer

tested this- only Vnet3 and vnet4.  interestingly it allows you to create the vnet2 with subnet with a warning.

Gbala · Answer

we are able to peer using global peering?

pouya1 · Answer

The given answer (D) is correct. The VNet1 and VNet2 have overlap. but there is no overlap between VNet2, VNet3, and VNet4 so they can peer with each other.  The only limitation is with VNet1 and VNet2, These 2 cannot peer with each other or peer with any other VNET that is already peered with ano of them. e.g. if VNet 3 is peered with VNet2, VNent3 cannot peer with VNet1 due to overlapping rule.

azayra · Answer

the anwer is correct they ask you for  vnet1.
 you do 1 to 1 conecction vnet1 to vnet2 , vnt1 to vnet3, vnet1 to vnet4 .
