Question
You have an Azure subscription that contains an Azure Standard Load Balancer named LB1. You plan to deploy a Windows failover cluster named Cluster1 that will host SAP Central Services (SCS). Cluster1 will be deployed across two Azure availability zones. You need to ensure that LB1 can support connections to Cluster1. Which two settings should you configure in the load balancing rule for LB1? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

Explanation
Some application scenarios prefer or require the use of the same port by multiple application instances on a single VM in the backend pool. Common examples of port reuse include clustering for high availability, network virtual appliances, and exposing multiple TLS endpoints without re-encryption. If you want to reuse the backend port across multiple rules, you must enable Floating IP in the rule definition. Enabling Floating IP allows for more flexibility. HA ports offer the following advantages: Provide fast failover to healthy instances, with per-instance health probes Ensure higher performance with scale-out to n-active instances Provide n-active and active-passive scenarios Eliminate the need for complex solutions, such as Apache ZooKeeper nodes for monitoring
