A Recovery Services vault is a logical container that stores the backup data for each protected resource, such as Azure VMs. When the backup job for a protected resource runs, it creates a recovery point inside the Recovery Services vault.

Scenario:

There are three application tiers, each with five virtual machines.

Move all the virtual machines for App1 to Azure.

Ensure that all the virtual machines for App1 are protected by backups.

Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers:

• A SQL database
• A web front end
• A processing middle tier

Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only.

• Technical requirements include:
• Move all the virtual machines for App1 to Azure.
• Minimize the number of open ports between the App1 tiers.

References: https://docs.microsoft.com/en-us/azure/architecture/reference-architectures/n-tier/n-tier-sql-server

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.

You can use a site-to-site VPN to connect your on-premises network to an Azure virtual network. Users on your on-premises network connect by using the RDP or

SSH protocol over the site-to-site VPN connection. You have to deny direct RDP or SSH access over the internet through an NSG.

To create a peering between two virtual networks, the address spaces of the virtual networks must not overlap. VNet1 has an address space of 10.0.0.0/16, which overlaps with VNet2’s address space of 10.2.0.0/16. Therefore, you need to modify the address space of VNet1 to a non-overlapping range, such as 10.1.0.0/16, before you can create the peering. You do not need to configure a service endpoint, add a gateway subnet, or create a subnet on either virtual network for the peering to work. Then, References: [Virtual network peering] [Modify a virtual network’s address space]

Azure Monitor can collect data directly from your Azure virtual machines into a Log Analytics workspace for analysis of details and correlations. Installing the Log Analytics VM extension for Windows and Linux allows Azure Monitor to collect data from your Azure VMs.

Azure Log Analytics workspace is also used for on-premises computers monitored by System Center Operations Manager.

https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azresourcegroupdeployment?view=azps-9.3.0#-resourcegroupname

Specifies the name of the resource group to deploy.

https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azresourcegroupdeployment?view=azps-9.3.0#-mode

Specifies the deployment mode. The acceptable values for this parameter are:

-Complete: In complete mode, Resource Manager deletes resources that exist in the resource group but are not specified in the template.

- Incremental: In incremental mode, Resource Manager leaves unchanged resources that exist in the resource group but are not specified in the template.

• WebApp1 can communicate with VM2. No, this is not correct. According to the tables, WebApp1 is integrated with VNet1, which has a peering connection with VNet2. However, VM2 is in VNet3, which is not peered with VNet1 or VNet2. Therefore, WebApp1 cannot communicate with VM2 across different virtual networks1.
• NSG1 controls inbound traffic to WebApp1. No, this is not correct. According to the tables, NSG1 is associated with Subnet1 in VNet1, which is integrated with WebApp1. However, network security groups only control outbound traffic from App Service apps to virtual networks, not inbound traffic to App Service apps from virtual networks2. Therefore, NSG1 does not control inbound traffic to WebApp1.
• WebApp2 can communicate with VM1. Yes, this is correct. According to the tables, WebApp2 is integrated with VNet3, which has a peering connection with VNet2. VM1 is in Subnet2 in VNet2, which has a network security group named NSG2 that allows inbound traffic from any source on port 803. Therefore, WebApp2 can communicate with VM1 on port 80 across peered virtual networks.

Moving the virtual machine to a different resource group does not change the host that the virtual machine runs on. It only changes the logical grouping of the resources. To move the virtual machine to a different host, you need to redeploy it or use Azure Site Recovery. Then, References: [Move resources to new resource group or subscription] [Redeploy Windows VM to new Azure node] [Use Azure Site Recovery to migrate Azure VMs between Azure regions]

The Logic App Operator role only grants the ability to read, enable, disable, and run logic apps. It does not grant the ability to create logic apps. To create logic apps, you need to assign the Logic App Contributor role or a higher-level role such as Owner or Contributor. Then, References: [Built-in roles for Azure resources] [Azure Logic Apps permissions and access control]

The Contributor role grants the ability to create and manage all types of Azure resources, including logic apps. Assigning this role to the Developers group on the Dev resource group will allow them to create logic apps in that scope. Then, References: [Built-in roles for Azure resources] [Azure Logic Apps permissions and access control]

Technically, The finance department needs to migrate their users from AD to AAD using AADC based on the finance OU, and need to enforce MFA use. This is conditional access policy. Employees also often get promotions and/or join other departments and when that occurs, the user's OU attribute will change when the admin puts the user in a new OU, and the dynamic group conditional access exception (OU= [Department Name Value]) will move the user to the appropriate dynamic group on next AADC delta sync.

Scenario: Litware must meet technical requirements including:

Ensure that VM3 can establish outbound connections over TCP port 8080 to the applications servers in the Montreal office.

IP flow verify checks if a packet is allowed or denied to or from a virtual machine. The information consists of direction, protocol, local IP, remote IP, local port, and remote port. If the packet is denied by a security group, the name of the rule that denied the packet is returned. While any source or destination IP can be chosen, IP flow verify helps administrators quickly diagnose connectivity issues from or to the internet and from or to the on-premises environment.

Scenario: Create a workflow to send an email message when the settings of VM4 are modified.

You can start an automated logic app workflow when specific events happen in Azure resources or third-party resources. These resources can publish those events to an Azure event grid. In turn, the event grid pushes those events to subscribers that have queues, webhooks, or event hubs as endpoints. As a subscriber, your logic app can wait for those events from the event grid before running automated workflows to perform tasks - without you writing any code.

Box 1: Create a virtual network gateway and a local network gateway.

Azure VPN gateway. The VPN gateway service enables you to connect the VNet to the on-premises network through a VPN appliance. For more information, see Connect an on-premises network to a Microsoft Azure virtual network. The VPN gateway includes the following elements:

• Virtual network gateway. A resource that provides a virtual VPN appliance for the VNet. It is responsible for routing traffic from the on-premises network to the VNet.
• Local network gateway. An abstraction of the on-premises VPN appliance. Network traffic from the cloud application to the on-premises network is routed through this gateway.
• Connection. The connection has properties that specify the connection type (IPSec) and the key shared with the on-premises VPN appliance to encrypt traffic.
• Gateway subnet. The virtual network gateway is held in its own subnet, which is subject to various requirements, described in the Recommendations section below.

Box 2: Configure a site-to-site VPN connection

On premises create a site-to-site connection for the virtual network gateway and the local network gateway.
