Cloud computing for education – UGC NET Question

Statements A, B, C and E correctly explain major cloud service models and a key benefit of scalability, whereas D and F are false. Institutions using cloud services do not have to own on-site data centres, and cloud tools are typically accessible from various devices including mobiles. Therefore, the combination of A, B, C and E only provides an accurate overview of cloud computing in education.

Option A:
Option A is correct because it captures the essence of IaaS, PaaS and SaaS while highlighting scalability as a practical advantage. By omitting D and F, it avoids misconceptions about mandatory on-premise centres and lack of mobile access. This combination reflects how many contemporary educational platforms actually operate.

Option B:
Option B is incorrect because it includes F, which wrongly asserts that cloud tools cannot be used on mobile devices. Cloud-based LMS and collaboration tools are routinely accessed via smartphones and tablets, so accepting F undermines accuracy.

Option C:
Option C is incorrect because it accepts F and omits B, thereby losing the explanation of PaaS. While A, C and E are true, the presence of F makes the entire combination invalid.

Option D:
Option D is incorrect because it includes D, which insists that institutions must always own physical data centres. In reality, cloud adoption often reduces the need for in-house server infrastructure, so this statement cannot be part of the correct set.
