What does clustering achieve? Saves memory Disables unused services High availability of services Limits processor usag

Clustering primarily achieves **high availability of services**. In a clustering setup, multiple servers (nodes) work together to ensure that applications and services remain accessible and resilient in the event of a failure of any single server. Clustering can also improve load balancing and performance by distributing tasks among nodes. While some of the other options listed may be side effects or benefits in certain contexts, high availability is the main goal of clustering.
