Box 1: A Recovery Services vault
A Recovery Services vault is an entity that stores all the backups and recovery points you create over time.
Box 2: A backup policy
What happens when I change my backup policy?
When a new policy is applied, schedule and retention of the new policy is followed.

A Recovery Services vault is a storage entity in Azure that houses data. The data is typically copies of data, or configuration information for virtual machines (VMs), workloads, servers, or workstations. You can use Recovery Services vaults to hold backup data for various Azure services such as IaaS VMs (Linux or Windows) and Azure SQL databases.
You can use backup policy to configure schedule.

Data Sources: VM1 only
Destination: Workspace1 Only

Explanation:

In this case, you have two alert rules: Alert1 and Alert2. Alert1 has a scope of RG1, which means it applies to all the resources in the resource group named RG1. Alert1 has a condition of All Administrative operations, which means it triggers when any administrative operation is performed on the resources in RG1. An administrative operation is any operation that changes the configuration or state of a resource, such as creating, deleting, updating, or restarting.
Alert2 has a scope of VM1, which means it applies only to the virtual machine named VM1. Alert2 also has a condition of All Administrative operations, which means it triggers when any administrative operation is performed on VM1.
Now, let's see which alert rules are triggered by each user.
User1 creates a new virtual disk and attaches the disk to VM1. This is an administrative operation on VM1, so it triggers Alert2. However, it does not trigger Alert1, because the new disk is not part of RG1. Therefore, the correct answer for User1 is C. Only Alert2 is triggered.
User2 creates a new resource tag and assigns the tag to RG1 and VM1. This is also an administrative operation on both RG1 and VM1, so it triggers both Alert1 and Alert2. Therefore, the correct answer for User2 is D. Alert1 and Alert2 are triggered.

As App1 is public-facing we need an incoming security rule, related to the access of the web servers.
Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers: a SQL database, a web front end, and a processing middle tier.
Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only.
