Question

How many Big SQL management node do you need at minimum?
A. 3
B. 4
C. 2
D. 1

Answer 1

You need a minimum of 2 Big SQL management nodes to ensure high availability and workload management in a Big SQL environment.

Step-by-step explanation:

The minimum number of Big SQL management nodes required is C. 2. Big SQL is a component of IBM's BigInsights which provides SQL access to data in Hadoop. The management nodes are critical for the operation of a Big SQL environment. They host services that manage and coordinate the Big SQL workload. Having at least two management nodes can ensure high availability and failover capabilities. When planning a Big SQL cluster, it is important to consider redundancy and resilience; therefore, a minimum of two nodes is recommended to handle management tasks and to protect against single points of failure.

Answer 2

At least three Big SQL management nodes are required for high availability and fault tolerance in a distributed computing environment.

The correct answer is a.

Step-by-step explanation:

The minimum number of Big SQL management nodes required is three. This is necessary to ensure high availability and fault tolerance. In a distributed computing environment, having at least three management nodes allows the system to continue functioning even if one node fails. The consensus protocols used for fault tolerance, such as Raft or Paxos, require an odd number of nodes to prevent split-brain scenarios and to allow the system to continue to make progress even when some nodes are not available.
