Question

In a Hadoop cluster, which two are the result of adding more nodes to the cluster? (Select two)

A) Increased storage capacity
B) Decreased processing power
C) Improved fault tolerance
D) Slower data processing

Answer 1

Adding more nodes to a Hadoop cluster increases storage capacity and improves fault tolerance.

Step-by-step explanation:

Adding more nodes to a Hadoop cluster has two main results:

1. Increased storage capacity: More nodes means more storage space available to store data. This allows for larger datasets to be processed and analyzed.
2. Improved fault tolerance: When more nodes are added, the data is spread across multiple machines, reducing the risk of data loss in case of a node failure.

Therefore, adding more nodes to a Hadoop cluster increases storage capacity and improves fault tolerance.
