Azure Application Gateway: Master Your Cloud Networking Interview

welcome to this video please don't forget to like And subscribe to our Channel let us start this video One what is an application Gateway an application Gateway is a web traffic load balancer that operates at the application layer layer 7 and provides Advanced rooting capabilities including SSL termination URL based routing web application firewall WF session affinity and health monitoring it ensures efficient traffic distribution and enhances security for web applications question two what layer of the OC model does an application Gateway operate at an application Gateway operates at the application layer layer 7 of the OC model enabling Intelligent roting Decisions based on HTTP requests URLs and headers question three which feature of an application Gateway helps to secure web application by inspecting incoming traffic the web application firewall WF feature inspects incoming traffic for malicious activities such as SQL injection cross-site scripting xss and other common web attacks providing an added layer of security question four what is the purpose of SSL termination in an application Gateway SSL termination allows the application gateway to decrypt https traffic before forwarding it to backend servers this reduces the processing burden on backend servers improves performance and enables features like traffic inspection and routing question five how does URL based routing work in an application Gateway URL based routing directs client requests to specific backend servers based on the requested URL for example requests to/ products can be sent to one server pool while requests to SL blog can be to another question six what is session Affinity in the context of an application Gateway session Affinity also known as cookie based Affinity ensures that a user's requests are consistently rooted to the same back-end server during a session this is useful for maintaining session state in applications that do not use distributed session storage question seven what does Health monitoring in an application Gateway do health monitoring continuously checks the status of backend servers by sending periodic Health proofs if a server becomes unhealthy or unresponsive the application Gateway automatically reroots traffic to healthy instances question eight what type of load balancing does an application Gateway provide an application Gateway provides layer 7 application layer load balancing allowing it to root requests based on HTTP attributes such as URLs headers and cookies unlike traditional layer for load balancers that operate at the transport level question n which as your service provides application Gateway functionality as your application Gateway is the cloud-based service provided by Microsoft AA for Intelligent Traffic management load balancing and web application security to question 10 can an application Gateway handle both HTTP and https traffic yes an application Gateway can handle both HTTP and https traffic enabling secure communication and SSL off loading for backend servers question 11 what is the main advantage of using an application Gateway over a traditional load balancer unlike traditional load balancers that operate at layer 4 an application Gateway provides Advanced routing capabilities such as URL based routing SSL termination of protection and session Affinity making it ideal for modern web applications question 12 how does an application Gateway improves security for web applications an application Gateway enhances security through features like web application firewall WF for attack prevention SSL termination for encrypted traffic management and secure communication between clients and backend servers question 13 what is the purpose of autoscaling in an application Gateway autoscaling allows an application gateway to dynamically adjust the number of instances based on real-time traffic demand ensuring Optimal Performance cost efficiency and high availability question 14 what protocol is commonly used for communication between an application Gateway and backend servers an application Gateway typically communicates with backend servers using HTTP or or https https is preferred when endtoend encryption is required for enhanced security question 15 what is a common use case for an application Gateway an application Gateway is commonly used to manage and distribute traffic for web applications ensuring High availability secure access and efficient request routing to backend servers question 16 what feature allows an application gateway to rout traffic based on HTT headers header-based rooting allows an application gateway to make rooting decisions based on HTTP headers enabling more granular traffic control such as directing mobile users to different backend servers question 17 what type of attacks can a web application firewall WF help protect against a web application firewall WF helps protect against common web- based attacks such as SQL injection cross-site scripting xss remote code execution and other a wasp top 10 vulnerabilities
