Question 1

A large global enterprise customer has a Big Data environment set up on Hadoop. After a year in operation they are now looking to extend access to multiple functions that will need different views into different aspects/portions of the data. As you consider these requirements, which of the following statements is TRUE and also applies to the scenario?

AHadoop does not support multi tenancy but can easily scale to support this by replicating data to new clusters with commodity hardware.

BHadoop can support multi tenancy but only if YARN is used, so if not already used, the customer will need to upgrade to a YARN supported version.

CVirtualization methods can be used to support multi-tenancy on Hadoop because one can easily replicate to additional cluster whenever there is a need.

DHadoop can support multi tenancy by using a cluster file system for storage, allowing all nodes to access the data.
