Cloud deployment models basics – UGC NET Question

Statements A, B and C correctly describe the public, private and hybrid deployment models in cloud computing, while D misrepresents the idea of community cloud. Public cloud is shared among many customers, private cloud belongs to one organisation and hybrid cloud combines both types. Community clouds are shared by several organisations with common concerns, not by a single individual user. Therefore, the combination that includes A, B and C but excludes D is the only fully correct option.

Option A:
Option A is correct because it recognises that statements A, B and C all align with standard definitions of cloud deployment models. It also implicitly rejects statement D, which wrongly claims that community cloud serves a single individual instead of a group of organisations. By covering the three major models without including the incorrect description, this option gives a complete and accurate picture.

Option B:
Option B is incorrect because it leaves out statement C about hybrid cloud. While A and B are true, excluding C ignores the important model where organisations mix public and private resources. Since the question asks for all correct statements, this incomplete combination cannot be accepted.

Option C:
Option C is incorrect because it includes statement D and omits A and C. Although B is true, D is wrong in limiting community cloud to an individual user. The absence of A and C further weakens this option, so it does not represent the full set of correct statements.

Option D:
Option D is incorrect because it accepts all four statements, thereby treating D as correct. Including D means accepting a false description of community cloud, and this invalidates the entire combination even though A, B and C are accurate.
