   Your organization requires that all Virtual Machine Scale Sets in your subscription use a specific VM size family and have a minimum of 3 instances. You need to enforce this requirement across all scale sets created by any user in the subscription. What should you configure?

   • AAn Azure Policy that audits or denies scale sets that do not use the required VM size and instance count
   • BA network security group that restricts traffic to the scale set instances
   • CA role-based access control (RBAC) assignment that restricts who can create scale sets
   • DA resource lock on the scale set resource group that prevents modifications

   Your organization requires that all Virtual Machine Scale Sets use a specific VM size and are deployed in approved regions. You need to enforce this at scale across multiple subscriptions. What should you use?

   • AAzure Policy with built-in or custom policies assigned to the management group.
   • BAzure Blueprints to deploy a pre-configured scale set.
   • CAzure Security Center recommendations to review scale set configurations.
   • DAzure RBAC roles to restrict who can create scale sets.

   A company runs a batch processing workload on a Virtual Machine Scale Set. The workload is CPU-intensive and demand varies unpredictably. You need to configure autoscale so that the scale set scales out when average CPU usage is high and scales in when it is low, while keeping at least 2 instances running. What should you configure?

   • ASet the instance count to 2 and manually increase it when CPU is high.
   • BSet the minimum instance count to 2, and create a scale-out rule when CPU > 75% and a scale-in rule when CPU < 25%.
   • CSet the default instance count to 2, and create a scale-out rule when CPU > 75% and a scale-in rule when CPU < 25%.
   • DSet the maximum instance count to 10 and create a schedule-based rule to scale out during business hours.

   You are deploying a Virtual Machine Scale Set in a virtual network that uses a subnet with an existing network security group (NSG). The scale set instances need to receive traffic from an Azure Load Balancer on port 80 and communicate with a database on port 1433 in a different subnet. What should you configure?

   • AConfigure the load balancer to use a different subnet that does not have an NSG
   • BDisable the existing NSG on the subnet and rely on the load balancer's security rules
   • CAssociate the existing NSG with the scale set's subnet and add rules to allow inbound port 80 from the load balancer and outbound port 1433 to the database subnet
   • DCreate a new NSG and associate it with each individual instance in the scale set
