Exam AZ-104 topic 5 question 135 discussion

Its VNET 3 only and /23 So we need a /23 mask, this means 512 IPs I am a total newbie with this so i tried to find out what the possible IP Ranges are: - VNET 1 10.1.128.0/23 = 10.1.128.0 - 10.1.129.255 (512 IPs) - Sub 1 10.1.128.0/24 = 10.1.128.0 - 10.1.128.255 (256) -> Not enough IPs available - VNET 2 192.168.0.0/16 = 192.168.0.0-192.168.255.255 - Sub21 192.168.0.0 /17 = 192.168.0.0 - 192.168.127.255 - Sub22 192.168.128.0/17 = 192.168.128.0 - 192.168.255.255 -> The subnets take out the whole range of VNET 2 - VNET 3 172.16.0.0/16 = 172.16.0.0 - 172.16.255.255 - Sub3 172.16.1.0/24 = 172.16.1.0 - 172.16.1.255 -> VNET 3 still has most of the range for a /23 available. For example we could make the following /23 subnet: 172.16.2.0/23 = 172.16.2.0 - 172.16.3.255 Please correct me if i am wrong!

the Answer should be BOX 1 VNET 1 or VNET3 only BOX2 /24 we have subnet mask either /24 or /17 from all subnets. the question did not say you can create a new subnet! therefore, /24 is the samllest subnet you can CHOOSE from the two. Both VNET1 and VNET 3 have the subnets with mask /24

WRONG VNet3 only /23

Box 1: VNet1 and Vnet3 Box 2: /26

1. Workload profile environment: /27 is the minimum subnet size required 2. Consumption-only environment: /23 is the minimum subnet size required the question didn't specify which one is used. but based on the smaller subnet possible, it should be #1. /27. yet it is not available from the answer, so the next up is /26 following that logic, i would think the correct answer is 1. VNet1 and Vnet3 2. /26

Process of elmination: • Uses its own virtual network. Vnet1 & 2 • Uses its own subnet. Vnet1 & 2 • Is connected to the smallest possible subnet. Cont App can require either a /23 (consumption only env's), or a /27 (workload profile env's). There is no /27 as an option, so the assumption is a /23 is required. Only place for a /23 is vnet3. Final answer: vnet3 only on /23

Analysis: Smallest Subnet: Subnet1: 10.1.128.0/24 (256 IP addresses) Subnet21: 192.168.0.0/17 (32,768 IP addresses) Subnet22: 192.168.128.0/17 (32,768 IP addresses) Subnet3: 172.16.1.0/24 (256 IP addresses) Both Subnet1 and Subnet3 have the smallest size with a /24 subnet mask. Virtual Network Selection: Since both VNet1 and VNet3 have subnets of the smallest size (/24), you can choose either of these virtual networks. Subnet Mask: The smallest possible subnet mask for the container app environment is /24. Conclusion: Virtual networks: VNet1 or VNet3 Subnet mask: /24

VNET1, VNET2, and VNET3. /28. it can use all VNETs, because it's located in the same region. the subnets listed are the VNET's subnet, the maximum available range to use. the requirement is to create the smallest subnet, The smallest supported IPv4 subnet is /29, and the largest is /2 (using CIDR subnet definitions). IPv6 subnets must be exactly /64 in size https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-faq /29 is not in the list, so the next one will be /28.

Wt is the correct answer......

container apps need at least 512 IP addresses: 1- Vnet 1 does not have enough the remaining from subnet 1 will be 256. 2-Vnet2 the is full equipied and we do not have any IPs available 3- Vnet3 is having 65536 IPs and only equipied with 512 IPs so we still have so much space to host our ( /23) app container. answer Vnet3 and /23

This question was in exam 01/03/2024

- VNet3 only - 23

Given Ans is correct: -BOX 1 VNET1 or VNET2 or VNET3 -BOX2 /26 https://learn.microsoft.com/en-us/azure/container-apps/networking?tabs=workload-profiles-env%2Cazure-cli

s per the following link /27 is the minimum subnet required https://learn.microsoft.com/en-us/azure/container-apps/networking?tabs=workload-profiles-env%2Cazure-cli#consumption-only-environment Hence all three VNets can be used because those are bigger than /27. To keep the subnet smallest we should use /26 prefix.

To meet the requirements of creating a container app environment named con-env1 that uses its own virtual network, its own subnet, and is connected to the smallest possible subnet, you should connect con-env1 to vnet1 and use subnet1 with the smallest subnet mask available. The available options are: vnet1: 10.1.128.0/23, subnet1: 10.1.128.0/24 vnet2: 192.168.0.0/16, subnet21: 192.168.0.0/17 vnet3: 172.16.0.0/16, subnet3: 172.16.1.0/24 So, the correct options are: Connect con-env1 to vnet1 Use the subnet subnet1 with the subnet mask 10.1.128.0/24

Q1: VNET 1 & VNET 3 Q2: /24 from Subnet1 or Subnet 3 (bigger than /27 & /23 as required below) Container Apps has two different environment types, which share many of the same networking characteristics with some key differences. 1. Workload profiles environment: /27 is the minimum subnet size required for virtual network integration. 2. Consumption only environment: /23 is the minimum subnet size required for virtual network integration.
