Overview -
The following section of the exam is a lab. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design. Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.
Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.

To start the lab -
You may start the lab by clicking the Next button.
Another administrator attempts to establish connectivity between two virtual networks named VNET1 and VNET2.
The administrator reports that connections across the virtual networks fail.
You need to ensure that network connections can be established successfully between VNET1 and VNET2 as quickly as possible.
What should you do from the Azure portal?

Suggested Answer: See solution below.
You can connect one VNet to another VNet using either a Virtual network peering, or an Azure VPN Gateway.
To create a virtual network gateway
Step1 : In the portal, on the left side, click +Create a resource and type 'virtual network gateway' in search. Locate Virtual network gateway in the search return and click the entry. On the Virtual network gateway page, click Create at the bottom of the page to open the Create virtual network gateway page.
Step 2: On the Create virtual network gateway page, fill in the values for your virtual network gateway.


Name: Name your gateway. This is not the same as naming a gateway subnet. It's the name of the gateway object you are creating.
Gateway type: Select VPN. VPN gateways use the virtual network gateway type VPN.
Virtual network: Choose the virtual network to which you want to add this gateway. Click Virtual network to open the 'Choose a virtual network' page. Select the
VNet. If you don't see your VNet, make sure the Location field is pointing to the region in which your virtual network is located.
Gateway subnet address range: You will only see this setting if you did not previously create a gateway subnet for your virtual network. If you previously created a valid gateway subnet, this setting will not appear.
Step 4: Select Create New to create a Gateway subnet.

Step 5: Click Create to begin creating the VPN gateway. The settings are validated and you'll see the "Deploying Virtual network gateway" tile on the dashboard.
Creating a gateway can take up to 45 minutes. You may need to refresh your portal page to see the completed status.
