Reveal correct answer
Correct answer: A
Explanation
A Cluster has one and only one driver.
Cluster node type
A cluster consists of one driver node and worker nodes.
You can pick separate cloud provider instance types for the driver and worker nodes, although by default the driver node uses the same instance type as the worker node. Different families of instance types fit different use cases, such as memory-intensive or compute-intensive workloads.
A. In a Cluster, there is typically only one driver responsible for coordinating the execution of tasks and communicating with the Cluster Manager. Having multiple drivers would lead to coordination issues and conflicts within the Cluster.
B. Having two drivers running in parallel in a Cluster would introduce unnecessary complexity and potential conflicts in task coordination. It is not a standard practice to have multiple drivers in a Cluster environment.
C. The number of drivers in a Cluster is not configurable between one and ten. Having multiple drivers in a Cluster can lead to inefficiencies, conflicts, and coordination challenges. It is best practice to have only one driver in a Cluster environment.
D. The number of drivers in a Cluster is not configurable between one and eight. Typically, there is only one driver in a Cluster to ensure efficient task coordination and communication with the Cluster Manager.
