Question 1:
You need to configure a custom error page for your Azure App Service web app to display a friendly message to users when an error occurs.
How can you create and configure a custom error page in App Service?
A. Use the Application settings in the Azure portal to define custom error handling
B. Deploy a custom error page to the wwwroot folder of your App Service and configure it via the Azure portal
C. Configure a custom error page using the web.config file in the sites root directory
D. Use the Error Pages feature in the Azure portal to define a custom error page
Answer: B,C and D
Explanation:
– Error Pages feature in Azure portal: You can configure custom error pages for specific HTTP error codes (e.g., 404, 500) using the Azure portal. This feature allows you to upload a custom HTML page or redirect to a custom URL.
– web.config file: You can configure custom error pages by adding error handling rules in the web.config file. This file is located in the root directory of your web app and allows you to define custom error pages for specific error codes.
– Deploy to wwwroot folder: You can deploy a custom error page to the wwwroot folder of your App Service and configure it using the Azure portal. This folder is the default document root for your web app.
The “Application settings“ option is not directly related to configuring custom error pages, so it‘s not a in this case.
Question 2:

A. Built-in policy definitions
B. Customized Policy Document
C. Custom policy definitions
D. Policy exemptions
Answer: A and C
Explanation:
Key points about Azure Policy definition types:
Built-in policy definitions: These are a great starting point and cover many common use cases, saving you time and effort.
Custom policy definitions: These offer flexibility and allow you to tailor policies to your specific requirements.
Policy initiatives: These help you organize and manage multiple policy definitions together, making governance easier.
Policy exemptions: These provide a way to handle exceptions to policy rules when necessary.
Question 3:
You need to upload large files to Azure Blob Storage efficiently. Which tools or libraries would you recommend for optimizing the upload process and ensuring reliable data transfer?
A. Azure Storage Estimator
B. Azure Blob Storage client library for .NET
C. Azure Data Box
D. AzCopy
Answer: B and D
Explanation:
The tools or libraries that I would recommend for optimizing the upload process and ensuring reliable data transfer when uploading large files to Azure Blob Storage are:
Azure Blob Storage client library for .NET: This library provides a high-level API for interacting with Azure Blob Storage from .NET applications. It includes features like automatic retries, batching, and progress tracking, which can help to improve upload performance and reliability.
AzCopy: AzCopy is a command-line utility that can be used to transfer data to and from Azure Blob Storage. It offers features like parallel transfers and resume capabilities, which can significantly speed up large file uploads.
Here are some additional tips for optimizing the upload process:
Use the correct blob type: Choose the appropriate blob type (block blob, append blob, or page blob) based on your data and access patterns.
Compress data before uploading: Compressing data can reduce the size of the files and improve upload speed.
Use chunking: For very large files, consider using chunking to upload the data in smaller chunks. This can improve reliability and allow you to resume uploads in case of interruptions.
Monitor upload progress: Use the progress tracking features provided by the client library or AzCopy to monitor the upload progress and identify any issues.
By following these recommendations and using the appropriate tools, you can optimize the upload process and ensure reliable data transfer to Azure Blob Storage.
Question 4:
You are implementing a network security group (NSG) for your Azure virtual network. You need to allow inbound traffic on port 443 for HTTPS access to your web servers.
How would you create an NSG rule to achieve this?
A. Create an inbound rule with source Any, destination Any, port 443, and action Allow.
B. Create an inbound rule with source Internet, destination Any, port 443, and action Allow.
C. Create an inbound rule with source VirtualNetwork, destination VirtualNetwork, port 443, and action Allow.
D. Create an outbound rule with source Any, destination Internet, port 443, and action Allow.
Answer: A
Explanation:
To allow inbound HTTPS traffic on port 443 to your web servers, you should create an inbound rule with the following settings:
Source: Any (to allow traffic from any source)
Destination: Any (to allow traffic to any destination within the virtual network)
Source port range: Any (to allow any source port)
Destination port range: 443
Protocol: TCP
Action: Allow
By creating this rule, you are effectively allowing any device outside or inside your virtual network to initiate an HTTPS connection to your web servers on port 443.
Therefore, the correct answer is: Create an inbound rule with source Any, destination Any, port 443, and action Allow.
Question 5:
You are configuring an internal load balancer for your Azure VMs. You need to ensure that only clients within the same virtual network can access the load-balanced resources.
How would you restrict access to the internal load balancer?
A. Assign a public IP address to the load balancer.
B. Configure a Network Security Group (NSG) on the load balancer‘s subnet.
C. Use a private frontend IP address for the load balancer.
D. Configure a User Defined Route (UDR) for the load balancer.
Answer: C
Explanation:
To restrict access to an internal load balancer to clients within the same virtual network, you should use a private frontend IP address.
Here’s why:
Private IP address: This ensures that the load balancer is only accessible within the virtual network.
Public IP address: This would expose the load balancer to the public internet, which is not desired in this case.
NSG: While NSGs can be used to control traffic flow, they are not the most efficient way to restrict access to an internal load balancer.
UDR: User Defined Routes are used to override the default route table and can be used to control traffic flow, but they are not necessary in this specific scenario.
By using a private frontend IP address, you can effectively limit access to the load balancer to clients within the virtual network, ensuring security and preventing unauthorized access.

Question 6:
Scenario:
Your company is developing a web application that needs to access Azure Storage resources (blobs and queues) securely. The application will be running on virtual machines within your Azure environment.
Question:
Which of the following methods provides the MOST secure way for your application to authenticate with Azure Storage and access the required resources?
A. Embed the Azure Storage account name and key in the application‘s source code.
B. Create a managed identity for the virtual machine and assign it the necessary Azure RBAC roles to access the storage account.
C. Store the Azure Storage account access keys in the application‘s configuration files.
D. Use a Shared Access Signature (SAS) token to grant limited and time-bound access to specific storage resources.
Answer: B
Explanation:
Managed Identities: Managed identities provide an identity for applications to use when connecting to resources that support Azure Active Directory (Azure AD) authentication.
Security: This approach eliminates the need to manage credentials in your application code or configuration files.
Role-Based Access Control (RBAC): You can use RBAC to grant the managed identity only the necessary permissions to access the required storage resources, following the principle of least privilege.
Key Points:
Managed identities offer a secure and convenient way for applications to authenticate with Azure services.
This approach is preferred over storing access keys or using SAS tokens, as it eliminates the need to manage credentials directly.
By using RBAC, you can control the level of access granted to the application, enhancing security.
Question 7:
You want to configure a custom domain for your Azure App Service web app, but you need to keep the original *.azurewebsites.net domain active for testing purposes.
How can you manage multiple domain bindings for your web app in Azure App Service?
A. Add the custom domain in the Custom domains section and retain the default domain
B. Use a wildcard DNS entry to manage both the custom and default domains
C. Set up domain redirection rules in the Azure portal
D. Create a custom CNAME record for your custom domain and map it to your Azure web app
Answer: A and D
Explanation:
The s are:
– Add the custom domain in the Custom domains section and retain the default domain
– Create a custom CNAME record for your custom domain and map it to your Azure web app
Here‘s a brief explanation of each option:
– Add custom domain and retain default domain: You can add a custom domain to your App Service web app while keeping the original *.(link unavailable) domain active. This allows you to have multiple domain bindings, and you can manage them in the Azure portal.
– Create a custom CNAME record: You need to create a CNAME record for your custom domain that points to your Azure web app. This record maps your custom domain to the Azure App Service infrastructure. You can add this record to your DNS provider, and then validate the custom domain in the Azure portal.
The other options are not entirely correct:
– Wildcard DNS entry: While wildcard DNS entries can be used for subdomains, they are not necessary for managing multiple domain bindings in Azure App Service.
– Domain redirection rules: You can set up redirection rules, but that‘s not directly related to managing multiple domain bindings.
By adding the custom domain and creating a CNAME record, you can successfully manage multiple domain bindings for your web app in Azure App Service.
Question 8:
Your company is migrating from on-premises storage to Azure Storage. Which Azure tools or services can you use to assess your current storage environment, plan your migration strategy, and estimate costs for Azure Storage?
A. Azure Migrate
B. Azure Storage Migration Service
C. Azure Pricing Calculator
D. Azure Cost Management
E. Azure Data Box
Answer: A, B, C and D
Explanation:
The correct tools and services for assessing your current storage environment, planning your migration strategy, and estimating costs for Azure Storage are:
Azure Migrate: This tool provides a comprehensive assessment of your on-premises storage environment, including inventory, dependencies, and compatibility with Azure Storage. It also helps you plan your migration strategy and estimate costs.
Azure Storage Migration Service: This service simplifies the migration of data from on-premises storage to Azure Storage. It supports various storage types and provides features like data validation, data transfer optimization, and progress tracking.
Azure Pricing Calculator: This tool allows you to estimate the costs of Azure Storage based on your specific usage patterns. You can input information about your storage requirements and usage patterns to get a detailed cost estimate.
Azure Cost Management: This tool helps you manage and optimize your Azure costs, including storage costs. It provides insights into your spending patterns, identifies cost-saving opportunities, and helps you set budgets and alerts.
While Azure Data Box is a useful tool for transferring large amounts of data to Azure, it is not specifically designed for assessing your current storage environment, planning your migration strategy, or estimating costs.
Therefore, the best tools and services for your migration needs are Azure Migrate, Azure Storage Migration Service, Azure Pricing Calculator, and Azure Cost Management.
Question 9:
Your company is implementing a multi-factor authentication (MFA) policy for enhanced security.
How can you integrate MFA with Azure Storage access to add an extra layer of protection for sensitive data?
A. Configure storage account firewall
B. Enable Azure AD Identity Protection
C. Use Azure Storage account Shared Access Signatures (SAS) with Azure AD credentials.
D. Use Shared Access Signatures (SAS)
Answer: C
Explanation:
The correct answer is: Use Azure Storage account Shared Access Signatures (SAS) with Azure AD credentials.
Here’s why:
Configuring storage account firewall is a good security measure, but it doesn’t directly integrate MFA.
Enabling Azure AD Identity Protection is a broader security measure that helps detect potential threats, but it doesn’t specifically address MFA for Azure Storage access.
Using Shared Access Signatures (SAS) without Azure AD credentials doesn’t provide MFA protection.
Using Azure Storage account Shared Access Signatures (SAS) with Azure AD credentials is the most effective way to integrate MFA with Azure Storage access. When you use SAS with Azure AD credentials, users will need to provide their Azure AD credentials and pass MFA verification before they can access the storage account using the SAS. This adds an extra layer of security by requiring a second factor of authentication.
Question 10:
You have a multi-tier application with VMs in different VNets. You need to enable secure communication between these VMs while minimizing the attack surface. Which Azure networking feature is designed for this purpose?
A. Azure Application Gateway
B. Azure Private Link
C. Azure Virtual Network Peering
D. Network Security Groups (NSGs)
Answer: C
Explanation:
The Azure networking feature designed for secure communication between VMs in different VNets while minimizing the attack surface is Azure Virtual Network Peering.
Here’s a breakdown of why Azure Virtual Network Peering is the best option:
Secure Communication: Azure Virtual Network Peering allows you to connect two or more virtual networks within the same Azure subscription or across different subscriptions. This creates a private, secure connection between the VMs in the different VNets, isolating them from the public internet and reducing the attack surface.
Reduced Attack Surface: By using Virtual Network Peering, you can avoid exposing your VMs to the public internet, which can significantly reduce the risk of attacks.
Flexibility: Virtual Network Peering provides flexibility in terms of connectivity options. You can choose between full mesh peering or hierarchical peering to connect your VNets based on your specific requirements.
The other options are not as suitable:
Azure Application Gateway: While Application Gateway provides load balancing and web application firewall capabilities, it is not specifically designed for secure communication between VMs in different VNets.
Azure Private Link: Private Link is used to privately connect your virtual networks to services within Azure or to your own on-premises services. While it can provide secure access to services, it is not the best option for general-purpose communication between VMs.
Network Security Groups (NSGs): NSGs are used to filter network traffic to and from your VMs. While they can be used to restrict access to certain resources, they do not provide the same level of connectivity and security as Virtual Network Peering.
By using Azure Virtual Network Peering, you can establish secure and private communication between your VMs in different VNets, minimizing the attack surface and protecting your application from unauthorized access.
