You plan to move a web application named App1 from an on-premises data center to Azure.
App1 depends on a custom COM component that is installed on the host server.
You need to recommend a solution to host App1 in Azure. The solution must meet the following requirements:
* App1 must be available to users if an Azure data center becomes unavailable.
* Costs must be minimized.
What should you include in the recommendation?

• A.In two Azure regions, deploy a load balancer and a virtual machine scale set.
• B.In two Azure regions, deploy a Traffic Manager profile and a web app.
• C.In two Azure regions, deploy a load balancer and a web app.
• D.Deploy a load balancer and a virtual machine scale set across two availability zones.

Box 1: Standard general-purpose v2
Standard general-purpose v2 supports Blob Storage.
Azure Storage provides data protection for Blob Storage and Azure Data Lake Storage Gen2.
Scenario:
Litware identifies the following security and compliance requirements:
* Once App1 is migrated to Azure, you must ensure that new data can be written to the app, and the modification of new and existing data is prevented for a period of three years.
* On-premises users and services must be able to access the Azure Storage account that will host the data in App1.
* Access to the public endpoint of the Azure Storage account that will host the App1 data must be prevented.
* All Azure SQL databases in the production environment must have Transparent Data Encryption (TDE) enabled.
* App1 must NOT share physical hardware with other workloads.
Box 2: NFSv3
Scenario: Plan: Migrate App1 to Azure virtual machines.
Blob storage now supports the Network File System (NFS) 3.0 protocol. This support provides Linux file system compatibility at object storage scale and prices and enables Linux clients to mount a container in Blob storage from an Azure Virtual Machine (VM) or a computer on-premises.

You deploy two instances of an Azure web app. One instance is in the East US Azure region and the other instance is in the West US Azure region. The web app uses Azure Blob storage to deliver large files to end users.
You need to recommend a solution for delivering the files to the users. The solution must meet the following requirements:
Ensure that the users receive files from the same region as the web app that they access.
Ensure that the files only need to be updated once.
Minimize costs.
What should you include in the recommendation?

• A.read-access geo-redundant storage (RA-GRS)
• B.geo-redundant storage (GRS)
• C.Distributed File System (DFS)
• D.Azure File Sync

You need to recommend a solution to ensure that App1 can access the third-party credentials and access strings. The solution must meet the security requirements.

Scenario: Security Requirement
All secrets used by Azure services must be stored in Azure Key Vault.
Services that require credentials must have the credentials tied to the service instance. The credentials must NOT be shared between services.
Box 1: A service principal
A service principal is a type of security principal that identifies an application or service, which is to say, a piece of code rather than a user or group. A service principal's object ID is known as its client ID and acts like its username. The service principal's client secret acts like its password.
Note: Authentication with Key Vault works in conjunction with Azure Active Directory (Azure AD), which is responsible for authenticating the identity of any given security principal.
A security principal is an object that represents a user, group, service, or application that's requesting access to Azure resources. Azure assigns a unique object ID to every security principal.
Box 2: A role assignment
You can provide access to Key Vault keys, certificates, and secrets with an Azure role-based access control.
