Manage virtual machines

HOTSPOT -

You have an Azure virtual machine scale set named vmssWeb.

vmssWeb hosts identical virtual machines that run Windows Server and have the Web Server (IIS) server role installed. vmssWeb has a fixed capacity of 10 virtual machine instances.

Monitoring shows the following patterns:

On Saturdays and Sundays, vmssWeb requires only two virtual machine instances by 7:00 AM.

During business days, launches by your company’s marketing department can cause unpredictable processor demand.

You need to configure capacity management for vmssWeb. The solution must meet the following requirements:

Automatically set weekend capacity to two virtual machine instances.

Increase capacity during business-day demand spikes.

Minimize manual intervention.

What should you configure for each requirement? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Weekend capacity:
Business-day demand spikes:
Explanation

A recurring autoscale profile lets a scale set apply a specific instance-count schedule that repeats every week on chosen days and times (for example, every Saturday and Sunday), so capacity drops to the required two instances automatically without an operator changing anything, which satisfies the requirement to minimize manual intervention for a known weekly pattern. Because the marketing department's launches create processor-demand spikes that are unpredictable and therefore cannot be pinned to a schedule, the correct response mechanism is a rule that reacts to the measured metric itself: a metric-based scale-out rule increases instance count automatically whenever CPU (or another chosen performance metric) crosses the configured threshold, so capacity is added exactly when real demand appears rather than on a fixed clock, again without manual action.
