Question
Your organization uses Microsoft Azure Application Gateway to manage traffic for a web application. The application experiences intermittent connectivity issues, and you suspect that some backend servers are not responding correctly.
You need to configure the system so that only healthy backend servers receive traffic.
Each correct answer presents part of the solution. Which three actions should you perform?
A. Configure custom health probes.
B. Enable autoscaling.
C. Enable connection draining.
D. Enable path-based routing.
E. Set routing rules to redirect traffic from unhealthy servers.
F. Configure a health probe for each server.
Answer
A. Configure custom health probes.
C. Enable connection draining.
E. Set routing rules to redirect traffic from unhealthy servers.
Explanation
Configuring custom health probes allows precise determination of server health, ensuring only healthy servers receive traffic. Enabling connection draining prevents disruption during server maintenance or failure by allowing ongoing requests to complete. Setting routing rules to redirect traffic from unhealthy servers ensures that only healthy servers handle requests. Enabling load balancing distributes traffic across servers but does not directly ensure server health. Enabling autoscaling adjusts the number of servers based on traffic load but does not ensure that only healthy servers receive traffic. Using a single health probe for all servers may not accurately reflect the health of individual servers, leading to potential misrouting of traffic.
