  1. Which Azure service would you use to create a private, isolated network within the Azure cloud?

    Answer: Azure Virtual Network (VNet)

    Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. It allows you to create an isolated and secure network environment where you can deploy your Azure resources, such as virtual machines and databases. VNets enable private communication between resources, both within the VNet and to on-premises networks.

  2. What is the primary purpose of Azure Network Security Groups (NSGs)?

    Answer: To control inbound and outbound network traffic to Azure resources

    Azure Network Security Groups (NSGs) are used to filter network traffic to and from Azure resources within an Azure Virtual Network. They allow you to define rules that permit or deny inbound and outbound traffic based on source/destination IP address, port, and protocol. This provides a crucial layer of security by controlling access to your virtual machines and subnets.

  3. Which Azure service provides a dedicated private connection between on-premises networks and Azure datacenters?

    Answer: Azure ExpressRoute

    Azure ExpressRoute provides a dedicated, private connection between your on-premises infrastructure and Azure datacenters. Unlike VPNs, ExpressRoute connections do not go over the public internet, offering higher bandwidth, lower latency, and greater reliability. This makes it ideal for hybrid cloud scenarios requiring consistent network performance.

  4. Which Azure service is designed for web application security, providing protection against common web-based attacks?

    Answer: Azure Application Gateway with WAF (Web Application Firewall

    Azure Application Gateway with Web Application Firewall (WAF) is specifically designed to protect web applications from common web-based attacks. The WAF component inspects incoming web traffic for threats like SQL injection, cross-site scripting, and other OWASP Top 10 vulnerabilities. It acts as a reverse proxy, securing your web applications before traffic reaches your backend servers.

  5. What is the function of Azure Load Balancer?

    Answer: To distribute incoming network traffic across multiple resources to improve availability

    Azure Load Balancer distributes incoming network traffic across multiple backend resources, such as virtual machines or virtual machine scale sets. Its primary function is to improve the availability and scalability of applications by ensuring no single server becomes a bottleneck. By distributing requests, it helps prevent downtime and enhances user experience.
