HOTSPOT -
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.
Answer Options
A
If the CPU threshold reaches 85 percent for 6 minutes, Scale1 will be running: 6 virtual machines. If the CPU threshold reaches 25 percent for 6 minutes, Scale1 will be running: 2 virtual machines.
Correct Answer
A: If the CPU threshold reaches 85 percent for 6 minutes, Scale1 will be running: 6 virtual machines. If the CPU threshold reaches 25 percent for 6 minutes, Scale1 will be running: 2 virtual machines.
Explanation
Box 1: 6 virtual machines -
The Autoscale scale out rule increases the number of VMs by 2 if the CPU threshold is 80% or higher. The initial instance count is 4 and rises to 6 when the 2 extra instances of VMs are added.
Box 2: 2 virtual machnes -
The Autoscale scale in rule decreases the number of VMs by 4 if the CPU threshold is 30% or lower. The initial instance count is 4 and thus cannot be reduced to 0 as the minimum instances is set to 2. Instances are only added when the CPU threshold reaches 80%.
