You create a virtual machine scale set named Scale1. Scale1 is configured as shown in the following exhibit.

Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.

Correct Answer:

Explanation

As cooling period and scale in and scale out durations are not displayed in the graphical view, so we need to consider the default values as below for these settings.
Cool down (minutes) : The amount of time to wait before the rule is applied again so that the autoscale actions have time to take effect. Default is 5 minutes.
Duration : The amount of time monitored before the metric and threshold values are compared. Default is 10 minutes.
Box 1: 4 virtual machines
The Autoscale scale out rule increases the number of VMs by 2 if the CPU threshold is 80% or higher for more than or equals to 10 mins due to default duration for scale in and out is 10 minutes. Since CPU utilization at 85% only lasts for 6 mins , it does not trigger the rules.
Hence no of virtual machines will be same as the initial value which is 4.
Box 2: 4 virtual machines
The Autoscale scale in rule decreases the number of VMs by 4 if the CPU threshold is 30% or lower for more than or equal to 10 mins. due to default duration for scale in and out is 10 minutes . Since CPU utilization at
30% only lasts for 6 mins , it does not trigger the rules. Hence after first 6 mins instance count will be same as initial count as 4. After that CPU utilization reached to 50% for 6 mins , which again would not trigger the scale in rule. Therefore no of virtual machines will be same as the initial value which is 4.

You have a virtual network named VNET1 that contains the subnets shown in the following table:

You have two Azure virtual machines that have the network configurations shown in the following table:

For NSG1, you create the inbound security rule shown in the following table:

For NSG2, you create the inbound security rule shown in the following table:

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation

Box 1: Yes
The inbound security rule for NSG1 allows TCP port 1433 from 10.10.2.0/24 (or Subnet2 where VM2 and VM3 are located) to 10.10.1.0/24 (or Subnet1 where VM1 is located) while the inbound security rule for NSG2 blocks TCP port 1433 from 10.10.2.5 (or VM2) to 10.10.1.5 (or VM1). However, the NSG1 rule has a higher priority (or lower value) than the NSG2 rule.
Box 2: Yes
No rule explicitly blocks communication from VM1. The default rules, which allow communication, are thus applied.
Box 3: Yes
No rule explicitly blocks communication between VM2 and VM3 which are both on Subnet2. The default rules, which allow communication, are thus applied.
