Question
You have five Azure virtual machines that run Windows Server 2016. The virtual machines are configured as web servers.
You have an Azure load balancer named LB1 that provides load balancing services for the virtual machines.
You need to ensure that visitors are serviced by the same web server for each request.
What should you configure?
A. Floating IP (direct server return) to Disabled
B. Idle Time-out (minutes) to 20
C. a health probe
D. Session persistence to Client IP
Answer
D. Session persistence to Client IP
Explanation
Session persistence is a feature of Azure load balancer that enables you to control how requests from clients are distributed to the backend servers. By setting session persistence to Client IP, you can ensure that all requests from the same client IP address are sent to the same web server for the duration of the session.
A. Floating IP (direct server return) to Disabled is incorrect because it is a feature of Azure load balancer that enables you to optimize network performance by allowing the backend servers to directly respond to the clients without going through the load balancer. It has nothing to do with session persistence or ensuring that visitors are serviced by the same web server.
B. Idle Time-out (minutes) to 20 is incorrect because it is a setting of Azure load balancer that determines how long the load balancer maintains an idle TCP connection with a backend server before closing it. It has nothing to do with session persistence or ensuring that visitors are serviced by the same web server.
C. a health probe is incorrect because it is a component of Azure load balancer that monitors the availability and responsiveness of the backend servers and removes any unhealthy servers from the load balancing pool. It has nothing to do with session persistence or ensuring that visitors are serviced by the same web server.
