A) VNet Peering
B) Azure VPN Gateway
C) Azure ExpressRoute
D) Azure Firewall
Answer: C)
Explanation:
A) VNet Peering: VNet Peering connects two virtual networks either within the same region or across different regions. The connection between the two networks is private and uses Azure’s high-throughput backbone, ensuring low-latency communication. While VNet Peering enables secure communication between virtual networks, it does not offer a private, high-performance connection to on-premises resources. Furthermore, VNet Peering might not provide the bandwidth, performance, or reliability required for certain high-traffic or hybrid scenarios that involve on-premises connectivity.
B) Azure VPN Gateway: Azure VPN Gateway allows you to securely connect Azure virtual networks to on-premises networks over the public internet. It provides IPsec/IKE encryption and enables point-to-site, site-to-site, or VNet-to-VNet connections. Although VPN Gateway can securely connect virtual networks in different regions, it relies on the public internet for transport. This makes it less suitable for high-performance, low-latency needs and introduces the potential for higher latency and lower reliability compared to other solutions.
C) Azure ExpressRoute: Azure ExpressRoute provides a private, dedicated connection between on-premises networks and Azure. This solution bypasses the public internet, ensuring that traffic between Azure and on-premises systems or between different Azure regions remains isolated from the public internet. ExpressRoute offers high bandwidth, low latency, and consistent performance, making it an ideal solution for large-scale, mission-critical applications that require reliable, high-performance connectivity between Azure virtual networks in different regions. ExpressRoute can also support hybrid connectivity scenarios where both Azure and on-premises resources need to communicate efficiently.
D) Azure Firewall: Azure Firewall is a managed security service that provides stateful packet inspection, filtering, and monitoring for traffic between virtual networks and external resources. While Azure Firewall helps secure virtual networks by filtering traffic and blocking unauthorized access, it does not provide private connectivity between Azure virtual networks or between Azure and on-premises systems. It is often used in conjunction with other networking solutions but does not offer the high-performance, low-latency connection that ExpressRoute provides.
Question 22:
You need to secure communications between two Azure virtual machines in different regions. You want to ensure that the traffic does not traverse the public internet. Which of the following should you configure?
A) VNet Peering
B) VPN Gateway

Its primary focus is on security rather than keeping resources up-to-date with the latest patches.
B) Azure Update Management: Azure Update Management is a service that helps you automate the process of patching and updating your Azure virtual machines. It allows you to track missing patches, schedule patching windows, and ensure that all your virtual machines are compliant with the latest security and software updates. You can configure automatic patching or manually approve patches based on your update policy. Azure Update Management is the most appropriate solution for ensuring your virtual machines are consistently up-to-date with the latest patches.
C) Azure Automation: Azure Automation provides a set of tools for automating the management of your Azure resources, including tasks like VM provisioning, configuration management, and patching. While it can be used to automate patching using custom runbooks, Azure Update Management is a more specialized service for managing updates and patches specifically for virtual machines.
D) Azure Virtual Machine Scale Sets: Azure Virtual Machine Scale Sets allow you to manage a large number of identical virtual machines that automatically scale based on demand. While scale sets provide automatic scaling and high availability for VMs, they do not manage patching or ensure that VMs are up-to-date with the latest security updates. You would need to integrate them with services like Azure Update Management for patching.
Question 39:
You need to secure access to Azure resources and ensure that users can only access resources they are authorized to use, based on their job roles. Which Azure service should you use to implement this solution?
A) Azure Active Directory (Azure AD)
B) Azure Role-Based Access Control (RBAC)
C) Azure Conditional Access
D) Azure Key Vault
Answer: B)
Explanation:
A) Azure Active Directory (Azure AD): Azure Active Directory (Azure AD) is a cloud-based identity and access management service. It helps manage users and their authentication across Azure and other Microsoft services. While Azure AD is essential for managing identities, it does not specifically handle access control to resources based on roles. Role-based access control is a separate mechanism that can be integrated with Azure AD for more granular control over resource access.
B) Azure Role-Based Access Control (RBAC): Azure RBAC is a powerful tool that helps you control access to Azure resources based on the roles assigned to users, groups, or service principals. By defining roles and permissions, you can ensure that users only have access to resources that they are authorized to use based on their job function or role. RBAC allows you to define permissions for a variety of actions, including read, write, and delete, and apply them at the resource, resource group, or subscription level. This makes RBAC the ideal service for securing access to Azure resources.
C) Azure Conditional Access: Azure Conditional Access allows you to enforce security policies based on conditions such as user location, device health, and authentication strength. While Conditional Access can be used to enforce policies for accessing resources (e.g., requiring MFA for remote access), it is not the primary tool for defining role-based access to Azure resources. It complements RBAC by providing more granular security conditions but does not replace RBAC for resource access control.
D) Azure Key Vault: Azure Key Vault is a service used for securely storing and managing sensitive information like keys, secrets, and certificates. While it helps protect critical data, it does not manage access control to Azure resources. Key Vault is primarily focused on security and encryption, not role-based access control to resources.
Question 40:
You need to create a high-availability solution for a web application deployed across multiple Azure regions. Which of the following services should you use to achieve this?
A) Azure Traffic Manager
B) Azure Application Gateway
C) Azure Load Balancer
D) Azure Front Door
Answer: D)
Explanation:
A) Azure Traffic Manager: Azure Traffic Manager is a DNS-based global traffic routing service that helps direct user traffic to different Azure regions based on routing methods such as performance, priority, or geographic location. While it can be used to distribute traffic across regions, it works at the DNS layer and is better suited for managing traffic distribution rather than providing complete high-availability features like global load balancing or automatic failover.
B) Azure Application Gateway: Azure Application Gateway is a Layer 7 load balancer designed for managing HTTP/HTTPS traffic. It is used to provide traffic routing and load balancing for web applications and includes features such as SSL termination, URL-based routing, and web application firewall. However, Application Gateway operates within a single region and does not support multi-region high availability out-of-the-box. It can be used in conjunction with Traffic Manager for cross-region traffic management.
C) Azure Load Balancer: Azure Load Balancer provides high availability and load balancing for applications by distributing traffic to virtual machines within a single region. It operates at Layer 4 (TCP/UDP) and is well-suited for scenarios where you need to load balance traffic between instances within the same region. However, it does not support global multi-region traffic distribution, making it unsuitable for multi-region high availability on its own.
D) Azure Front Door: Azure Front Door is a global load balancing and application delivery service that provides high availability and low-latency access to applications. It operates at the application layer (Layer 7) and can distribute traffic across multiple Azure regions. Azure Front Door offers global load balancing, automatic failover, SSL offloading, and web application firewall features. It is specifically designed for providing high availability for applications across multiple regions, making it the ideal solution for global load balancing and high availability.
