Question 2
HOTSPOT
You have an Azure web app named App1 that has the following configurations:
* The app runs on three instances.
* The minimum number of instances is one.
* The maximum number of instances is five.
You create the following autoscale rules for App1:
* Decrease the instance count by one when the CPU percentage is less than 30.
* Decrease the instance count by one when the memory percentage is less than 50.
* Increase the instance count by one when the CPU percentage is greater than 80.
* Increase the instance count by one when the memory percentage is greater than 75.
You expect App1 to be utilized as shown in the following table.
You need to identify the maximum number of instances that will be used by App1 during the expected periods of utilization.
What should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:
Explanation
On scale out, autoscale runs if any rule is met. On scale-in, autoscale requires all rules to be met. Therefore, the web app will scale out but will never scale back in because there is no time where the CPU is less than
30% AND the memory is less than 50%.
Question 3
You have a virtual network named VNet1 as shown in the exhibit.
No devices are connected to VNet1.
You plan to peer VNet1 to another virtual network named Vnet2 in the same region. VNet2 has an address space of 10.2.0.0/16.
You need to create the peering.
What should you do first?

Question 9
Click to expand each objective. To connect to the Azure portal, type https://portal.azure.com in the browser address bar.
When you are finished performing all the tasks, click the 'Next' button.
Note that you cannot return to the lab once you click the 'Next' button. Scoring occur in the background while you complete the rest of the exam.
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.

What should you do from the Azure portal?
Correct Answer:
See solution below.
Explanation
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.
