A. B. C. D.D.
Distributed resource scheduling (DRS) is used within all clustered systems as the method for providing high availability, scaling, management, workload distribution, and the balancing of jobs and processes.
None of the other choices is the correct term in this case.
The process used within a clustered system to ensure proper load balancing and maintain the health of the overall system is distributed resource scheduling.
Clustered systems are composed of multiple individual systems working together as a single entity to achieve a common goal. The aim of clustering is to improve the availability, scalability, and performance of the system. High availability is achieved by ensuring that the system remains operational and responsive in the event of a failure in one or more of its components.
Load balancing is an essential component of clustering as it distributes incoming requests across the various systems within the cluster. This helps to avoid any one system from becoming overloaded, and also ensures that resources are used efficiently.
Distributed resource scheduling is the process of allocating resources such as CPU time, memory, and storage to different systems within the cluster. It involves monitoring the usage of these resources and dynamically adjusting their allocation based on the current workload of the system. This ensures that the system is always utilizing its resources to the fullest extent possible, and that no individual system becomes overburdened.
Distributed resource scheduling also helps to maintain the health of the overall system by detecting and responding to any potential issues. If a particular system within the cluster experiences a problem, such as a hardware failure or a software issue, the distributed resource scheduler can automatically redirect incoming requests to other systems within the cluster. This helps to prevent any downtime or disruption to the service.
In summary, the process used within a clustered system to ensure proper load balancing and maintain the health of the overall system is distributed resource scheduling. It is a dynamic process that involves allocating resources to different systems within the cluster based on the current workload, and detecting and responding to any potential issues to ensure high availability.
