Question 4 Topic 9, Mixed Questions
HOTSPOT
You have an Azure web app named App1 that contains the following autoscale conditions: The default auto created scale
condition has a scale mode that has Scale to a specific instance count set to 2.
Scale condition 1 has the following configurations:
Scale mode: Scale to a specific instance count
Instance count: 3
Schedule: Specify start/end dates
Start date: August 1, 2019, 06:00
End date: September 1, 2019, 18:00

Instance count: 5
Schedule: Repeat specific days
Repeat every: Monday
Start time: 15:00 End time: 20:00
You need to identify the number of running App1 instances.
What should you identify? To answer, select the appropriate options in the answer area.
Hot Area:
Answer:
Explanation:
Box 1: 5
Scale condition 1, Scale condition 2, and Scale condition 3 applies.
Scale condition 3 takes precedence as it the largest increase in the number of instances.
Box 2: 5
Scale condition 1 does not apply as its end date is exceeded.
Scale condition 2 and Scale condition 3 applies.
Scale condition 3 takes precedence as it the largest increase in the number of instances.
When you configure multiple policies and rules, they could conflict with each other. Autoscale uses the following conflict
resolution rules to ensure that there is always a sufficient number of instances running:
Scale-out operations always take precedence over scale-in operations.
When scale-out operations conflict, the rule that initiates the largest increase in the number of instances takes
precedence.
When scale in operations conflict, the rule that initiates the smallest decrease in the number of instances takes
precedence.

Question 13 Topic 9, Mixed Questions
A company is migrating an existing on-premises third-party website to Azure. The website is stateless.
The company does not have access to the source code for the website. They have the original installer.
The number of visitors at the website varies throughout the year. The on-premises infrastructure was resized to
accommodate peaks but the extra capacity was not used.
You need to implement a virtual machine scale set instance.
What should you do
- A. Use an autoscale setting with unlimited maximum number of instances.
- B. Use an autoscale setting to scale instances vertically.
- C. Use only default diagnostics metrics to trigger autoscaling.
- D. Use Azure Monitor to create autoscale settings using custom metrics.
Answer:
D
Explanation:
With Azure Monitor you can auto scale by custom metric for Virtual Machine Scale Sets.
Note: By default, Resource Manager-based Virtual Machines and Virtual Machine Scale Sets emit basic (host-level) metrics.
In addition, when you configure diagnostics data collection for an Azure VM and VMSS, the Azure diagnostic extension also
emits guest-OS performance counters (commonly known as "guest-OS metrics"). You use all these metrics in autoscale
rules.
Note 2: In-guest VM metrics with the Azure diagnostics extension
The Azure diagnostics extension is an agent that runs inside a VM instance. The agent monitors and saves performance
metrics to Azure storage. These performance metrics contain more detailed information about the status of the VM, such as
AverageReadTime for disks or PercentIdleTime for CPU. You can create autoscale rules based on a more detailed
awareness of the VM performance, not just the percentage of CPU usage or memory consumption.
