Azure 451-475

You have an Azure subscription.
You need to use Azure Cloud Shell to run a deployment script.
What should you use to access Cloud Shell?

• Azure Resource Manager (ARM)

• Microsoft Visual Studio

• a Windows command prompt

• a web browser

Answer explanation

• Azure Cloud Shell is a browser-based shell that provides an environment to run scripts, manage resources, and interact with Azure. You can access Azure Cloud Shell directly from a web browser by navigating to the Azure portal or going to shell.azure.com.

Why not the other options?

❌ Azure Resource Manager (ARM):

• Azure Resource Manager (ARM) is the service responsible for managing and deploying Azure resources but is not used to access Cloud Shell.

❌ Microsoft Visual Studio:

• Visual Studio is an integrated development environment (IDE) and isn't the method to access Azure Cloud Shell. Although you can use Visual Studio to work with Azure, it doesn't provide direct access to Cloud Shell.

❌ A Windows command prompt:

• The Windows command prompt can be used for running local commands on your machine, but it doesn’t directly access Azure Cloud Shell. Cloud Shell is a web-based service, not a local command line tool.

Answer explanation

1️⃣ For the platform as a service (PaaS) cloud service, updating the operating system is the responsibility of the customer. ❌ NO

• In PaaS, the cloud provider (e.g., Microsoft) manages the underlying infrastructure, including the operating system. The customer is responsible for managing their applications and data, but not the OS.

2️⃣ For the infrastructure as a service (IaaS) cloud service, network control is the responsibility of Microsoft. ❌ NO

• In IaaS, network control is primarily the responsibility of the customer, as they control the virtual machines (VMs) and networking configuration. The cloud provider manages the physical infrastructure, but the customer manages network settings like IP addresses, security groups, and firewalls.

3️⃣ For the software as a service (SaaS) cloud service, identity management is a shared responsibility between the customer and Microsoft. ✅ YES

• In SaaS, identity management is a shared responsibility. Microsoft typically handles the underlying infrastructure and software maintenance, but the customer is responsible for managing user identities, roles, and permissions within the application (e.g., setting up users in Office 365 or assigning access rights).

Select if the statement is YES. Otherwise, select NO.

Answer explanation

1️⃣ Creating and configuring a virtual network is part of the platform as a service (PaaS) cloud service model. ❌ NO

• Creating and configuring a virtual network is generally part of Infrastructure as a Service (IaaS) or Software as a Service (SaaS) models. In PaaS, the network is typically abstracted away from the user, and the cloud provider handles much of the underlying infrastructure, so configuring a virtual network would not be the customer's responsibility in this model.

2️⃣ In the platform as a service (PaaS) cloud service model, updating code for an Azure web app is the customer's responsibility. ✅ YES

• In PaaS, the customer is responsible for updating the application code and managing the app’s functionality, while the cloud provider takes care of the underlying infrastructure, including OS updates, scaling, and patching.

3️⃣ Configuring user access to a platform as a service (PaaS) cloud service model is the customer's responsibility. ✅ YES

• In PaaS, user access configuration is generally the customer’s responsibility. The customer manages identity and access control for their applications, often using tools like Azure Active Directory.

You need to migrate an on-premises server by using a lift-and-shift migration.
To which type of cloud service should you migrate?

• infrastructure as a service (IaaS)

• software as a service (SaaS)

• platform as a service (PaaS)

Answer explanation

1️⃣ Only one tag can be assigned to an Azure resource. ❌ NO

• Multiple tags can be assigned to a single Azure resource. Tags are key-value pairs, and you can assign several tags to a resource to organize and manage it effectively.

2️⃣ Tags can be assigned to Azure resources by using Azure Resource Manager (ARM) templates. ✅ YES

• ARM templates can indeed be used to define and assign tags to Azure resources as part of the deployment process.

3️⃣ Tags can be used to enforce naming standards for Azure resources. ❌ NO

• Tags are typically used for organizing, tracking, and reporting on Azure resources, but they do not enforce naming standards. Azure policies are used to enforce naming standards, not tags.

Answer explanation

Conditional Access in Azure Active Directory (Azure AD) evaluates signals such as user location, device state, and application sensitivity to determine whether to allow or deny access to Azure AD resources. It helps organizations enforce security policies based on specific conditions.

Answer explanation

1. Provides software emulation of a physical computer.
   Answer: Azure Virtual Machine Scale Sets
   Explanation: Azure Virtual Machine Scale Sets provide a way to deploy and manage a set of identical, auto-scaling virtual machines, effectively emulating physical computers.

2. Provides operating system virtualization.
   Answer: Azure Container Instances
   Explanation: Azure Container Instances allow you to run containers without managing the underlying infrastructure, thus utilizing operating system-level virtualization technology.

1️⃣ Azure Advisor supports alerts. ❌ NO

• Azure Advisor does not directly support alerts. It provides recommendations for improving Azure resources in areas like cost, security, performance, and high availability, but you cannot set alerts directly from Advisor. However, you can configure Azure Monitor to receive alerts based on the recommendations provided by Azure Advisor.

2️⃣ Azure Advisor recommendations can be filtered by Administrative unit. ❌ NO

• Azure Advisor recommendations are generally not filtered by Administrative units. They are filtered by resource type, subscription, or recommendations category (e.g., cost, security), but Administrative units is not a filtering option.

3️⃣ Azure Advisor provides recommendations on improving the performance of resources. ✅ YES

• Azure Advisor does provide performance-related recommendations, such as suggestions for optimizing resource configurations to improve overall performance (e.g., right-sizing virtual machines, optimizing storage).

Select if the statement is YES. Otherwise, select NO.

Answer explanation

1️⃣ You must install Azure Cloud Shell on your computer before you can use it. ❌ NO

• Azure Cloud Shell is a browser-based tool, meaning you do not need to install anything on your computer. You can access it directly from the Azure portal or via shell.azure.com.

2️⃣ The Azure Command-Line Interface (CLI) is installed by default in Windows 11. ❌ NO

• The Azure CLI is not pre-installed by default on Windows 11. You need to manually install it if you want to use it on Windows 11.

3️⃣ Azure PowerShell can be used on computers that run Windows, Linux, or macOS. ✅ YES

• Azure PowerShell is available for use on Windows, Linux, and macOS, allowing you to manage Azure resources across multiple platforms.

1️⃣ The Total Cost of Ownership (TCO) Calculator displays the cost of running workloads in a datacenter. ✅ YES

• The TCO Calculator helps you compare the costs of running workloads in an on-premises datacenter versus running them in Azure.

2️⃣ The Total Cost of Ownership (TCO) Calculator displays the cost of running workloads in Azure. ✅ YES

• The TCO Calculator estimates the cost of running workloads in Azure, providing a comparison between on-premises infrastructure and Azure-based services.

3️⃣ The Total Cost of Ownership (TCO) Calculator generates graphical reports. ✅ YES

• The TCO Calculator generates graphical reports to help visualize the comparison of costs, highlighting potential savings and providing a clear breakdown of the estimated total cost.
