3V's are not sufficient to describe big data.
Discuss
Answer & Solution
Answer: Option A
Solution:
The 3V's (Volume, Velocity, and Variety) were initially used to describe big data.

However, over time, it was recognized that these three aspects alone are not sufficient to fully define the complexities of big data.

Other characteristics like Veracity (data quality), Value (usefulness), and Variability (inconsistency of data) have also been added to better describe big data.

Therefore, the statement that the 3V's are not sufficient is True.
