Answer :

Final answer:

Session affinity, also known as sticky sessions, is not recommended for load balancing in Exchange 2016 due to uneven workload distribution, reduced scalability, and limited resilience.

Explanation:

Session affinity, also known as sticky sessions, is a load balancing technique that aims to direct requests from the same client to the same server. However, it is not recommended to use session affinity for load balancing in Exchange 2016 for several reasons.

  1. Uneven distribution of load: Session affinity can result in an uneven distribution of the workload across the servers. If some servers receive more requests than others, it can lead to performance issues and potentially overload certain servers.
  2. Reduced scalability: Session affinity limits the scalability of the Exchange infrastructure as it restricts the flexibility of routing requests to different servers. It may become challenging to add or remove servers without disrupting the established session affinity.
  3. Resilience and fault tolerance: By not using session affinity, Exchange 2016 can better handle server failures or maintenance tasks. Requests can be easily redirected to other servers without the need to maintain session state, ensuring higher resilience and fault tolerance.
