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.

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.

Box1 = To minimize the network costs of accessing adatum22, modify the Default routing tier setting. 

The default routing tier setting determines how network traffic is routed from the internet to the storage account. By default, the Microsoft global network routing option is selected, which means that traffic is routed over the Microsoft global network for the bulk of its path, maximizing network performance and reliability. However, this option also incurs network charges for data transfer between different Azure regions. The internet routing option, on the other hand, minimizes the traversal of traffic over the Microsoft global network, handing it off to the transit ISP at the earliest opportunity. This option lowers networking costs, but may compromise network performance and reliability. Therefore, to minimize the network costs of accessing adatum22, which is located in the East US region, from the West US region, you should modify the default routing tier setting to use internet routing instead of Microsoft global network routing. For more information, see Network routing preference for Azure Storage.

AKS clusters can scale in one of two ways: - The cluster autoscaler watches for pods that can't be scheduled on nodes because of resource constraints. The cluster then automatically increases the number of nodes. - The horizontal pod autoscaler uses the Metrics Server in a Kubernetes cluster to monitor the resource demand of pods. If an application needs more resources, the number of pods is automatically increased to meet the demand. Reference: https://docs.microsoft.com/en-us/azure/aks/cluster-autoscaler

Box1 : 10.0.0.0/16

Address prefix in networking refer to the destination IP address range. In this scenario, destination is Vnet1 , hence Address prefix will be the address space of Vnet1.

Box 2 : Virtual appliance

Next hop gets the next hop type and IP address of a packet from a specific VM and NIC. Knowing the next hop helps you determine if traffic is being directed to the intended destination, or whether the traffic is being sent nowhere

Next Hop --> VM1 --> Virtual Appliance (You can specify IP address of VM 1 when configuring next hop as virtual appliance)

Box 3 : GatewaySubnet

In the scenario it is asked for all the inbound traffic to Vnet1. Inbound traffic is flowing through SubnetGW. You need to route all inbound traffic from the VPN gateway to VNet1 through VM1.So its traffic from Gateway subnet only.

A custom policy definition is a way to define your own rules for using Azure resources. You can use custom policies to enforce compliance, security, cost management, or organization-specific requirements. However, a custom policy definition alone is not enough to meet the goal of automatically blocking TCP port 8080 between the virtual networks. You also need to create a policy assignment that applies the custom policy definition to the scope of the subscription. A policy assignment is the link between a policy definition and an Azure resource. Without a policy assignment, the custom policy definition will not take effect. Therefore, the solution does not meet the goal.

On October 10, you can read Dep1File1.docx. = NO 

Dep1File1.docx is a blob in container1 that was uploaded on October 1 and edited on October 2. According to the lifecycle management rule 1, any blob in container1 that has not been modified for 7 days will be moved to the archive tier. Therefore, on October 9, Dep1File1.docx will be moved to the archive tier. Blobs in the archive tier cannot be read unless they are first rehydrated, which may take several hours or days. Therefore, on October 10, you cannot read Dep1File1.docx unless you rehydrate it first.

On October 10, you can read File2.docx. = YES 

File2.docx is a blob in container1 that was uploaded on October 1 and edited on October 5. According to the lifecycle management rule 1, any blob in container1 that has not been modified for 7 days will be moved to the archive tier. Therefore, on October 12, File2.docx will be moved to the archive tier. However, on October 10, File2.docx is still in the hot tier, which means it can be read without any delay or cost.

On October 10, you can read File3.docx. = NO 

File3.docx is a blob in container1 that was uploaded on October 1 and edited on October 2. According to the lifecycle management rule 2, any blob in container1 that has not been modified for 5 days will be deleted. Therefore, on October 7, File3.docx will be deleted from the storage account. Therefore, on October 10, you cannot read File3.docx because it no longer exists.

D: Seamless SSO works with any method of cloud authentication - Password Hash Synchronization or Pass-through Authentication, and can be enabled via Azure AD Connect.

B: You can gradually roll out Seamless SSO to your users. You start by adding the following Azure AD URL to all or selected users' Intranet zone settings by using Group Policy in Active Directory: https://autologon.microsoftazuread-sso.com

Statement 1: Yes

All client computers in the Paris office will be joined to an Azure AD domain.

A virtual network named Paris-VNet that will contain two subnets named Subnet1 and Subnet2.

Microsoft Windows Server Active Directory domains, can resolve DNS names between virtual networks. Automatic registration of virtual machines from a virtual network that's linked to a private zone with auto-registration enabled. Forward DNS resolution is supported across virtual networks that are linked to the private zone.

Statement 2: Yes

A virtual network named ClientResources-VNet that will contain one subnet named ClientSubnet You plan to create a private DNS zone named humongousinsurance.local and set the registration network to the ClientResources-VNet virtual network.

As this is a registration network so this will work.

Statement 3: No

Only VMs in the registration network, here the ClientResources-VNet, will be able to register hostname records. Since Subnet4 not connected to Client Resources Network thus not able to register its hostname with humongoinsurance.local

You can opt in and configure additional recipients to receive your Azure invoice in an email. This feature may not be available for certain subscriptions such as support offers, Enterprise Agreements, or Azure in Open.

Select your subscription from the Subscriptions page. Opt-in for each subscription you own. Click Invoices then Email my invoice.

Click Opt in and accept the terms.

Scenario: During the testing phase, auditors in the finance department must be able to review all Azure costs from the past week.

Scenario: Licensing Issue

1. You attempt to assign a license in Azure to several users and receive the following error message: "Licenses not assigned. License agreement failed for one user."

2. You verify that the Azure subscription has the available licenses.

Solution:

License cannot be assigned to a user without a usage location specified.

Some Microsoft services aren't available in all locations because of local laws and regulations. Before you can assign a license to a user, you must specify the Usage location property for the user. You can specify the location under the User > Profile > Settings section in the Azure portal.

Once the VNets are peered, all resources on one VNet can communicate with resources on the other peered VNets. You plan to enable peering between Paris-VNet and AllOffices-VNet. Therefore VMs on Subnet1, which is on Paris-VNet and VMs on Subnet3, which is on AllOffices-VNet will be able to connect to each other.

All Azure resources connected to a VNet have outbound connectivity to the Internet by default. Therefore VMs on ClientSubnet, which is on ClientResources-VNet will have access to the Internet; and VMs on Subnet3 and Subnet4, which are on AllOffices-VNet will have access to the Internet.

IdFix is used to perform discovery and remediation of identity objects and their attributes in an on-premises Active Directory environment in preparation for migration to Azure Active Directory. IdFix is intended for the Active Directory administrators responsible for directory synchronization with Azure Active Directory.

Scenario: Active Directory Issue

Explanation

Scenario:

1. Web administrators will deploy Azure web apps for the marketing department.

2. Each web app will be added to a separate resource group.

3. The initial configuration of the web apps will be identical.

4. The web administrators have permission to deploy web apps to resource groups.

Steps:

1 --> Create a resource group, and then deploy a web app to the resource group.

2 --> From the Automation script blade of the resource group , click Add to Library.

3 --> From the Templates service, select the template, and then share the template to the web administrators .

Cost analysis: Correct Option

In cost analysis blade of Azure, you can see all the detail for custom time span. You can use this to determine expenditure of last few day, weeks, and month. Below options are available in Cost analysis blade for filtering information by time span:  last 7 days, last 30 days, and custom date range. Choosing the first option (last 7 days) auditors can view the costs by time span.

Cost analysis shows data for the current month by default. Use the date selector to switch to common date ranges quickly. Examples include the last seven days, the last month, the current year, or a custom date range. Pay-as-you-go subscriptions also include date ranges based on your billing period, which isn't bound to the calendar month, like the current billing period or last invoice. Use the  links at the top of the menu to jump to the previous or next period, respectively. For example, 

Invoice: Incorrect Option

Invoices can only be used for past billing periods not for current billing period, i.e. if your requirement is to know the last week's cost then that also not filled by invoices because Azure  generates invoice at the end of the month. Even though Invoices have custom timespan, but when you put in dates for a week, the pane would be empty. Below is from Microsoft document:

Resource Provider: Incorrect Option

When deploying resources, you frequently need to retrieve information about the resource providers and types. For example, if you want to store keys and secrets, you work with the Microsoft.KeyVault resource provider. This resource provider offers a resource type called vaults for creating the key vault. This is not useful for reviewing all Azure costs from the past week which is required for audit.

Payment method: Incorrect Option

Payment methods is not useful for reviewing all Azure costs from the past week which is required for audit.

Every Azure AD directory comes with an initial domain name in the form of domainname.onmicrosoft.com.

The initial domain name cannot be changed or deleted, but you can add your corporate domain name to Azure AD as well. For example, your organization probably has other domain names used to do business and users who sign in using your corporate domain name. Adding custom domain names to Azure AD allows you to assign user names in the directory that are familiar to your users, such as ‘alice@contoso.com.’ instead of 'alice@domain name.onmicrosoft.com'.

Scenario:

Network Infrastructure: Each office has a local data center that contains all the servers for that office. Each office has a dedicated connection to the Internet.

Humongous Insurance has a single-domain Active Directory forest named humongousinsurance.com

Planned Azure AD Infrastructure: The on-premises Active Directory domain will be synchronized to Azure AD.
