UGC NET Questions (Paper – 1)

Statements A, B and D are consistent with the accepted understanding of IoT and its campus applications, while C is clearly wrong. IoT nodes can include environmental sensors, RFID-enabled devices and smart meters that feed data into analytics systems. Automated attendance and resource optimisation are realistic use cases in many institutions. The assertion in C that IoT devices can never collect environmental data ignores common sensor types deployed in smart buildings.

Option A:
Option A is incomplete because it selects only A and B and overlooks D. While definition and attendance use are important, ignoring resource optimisation misses another major benefit of IoT in managing campus facilities efficiently.

Option B:
Option B is correct because it combines all three true statements and excludes C, which unduly restricts the capabilities of IoT sensors. It reflects how IoT can enhance administrative, learning and environmental aspects of educational spaces.

Option C:
Option C is incomplete because it lists B and D only and omits A. Without the general definition of IoT given in A, understanding of the technology behind the applications is incomplete.

Option D:
Option D is incorrect because it treats all four statements as correct and thus accepts C. Since C contradicts widespread use of temperature and air-quality sensors in IoT deployments, this option cannot be accepted.

Statements A, B and D provide a realistic view of VR and AR in education, while C dismisses their educational potential. VR and AR can create immersive and context-rich learning experiences, but their adoption is constrained by cost and complexity. Many educational simulations and visualisations already use these technologies. Thus, the correct combination includes A, B and D and excludes C.

Option A:
Option A is incomplete because it includes only A and B and ignores D. Recognising the challenges described in D is important for a balanced understanding of VR and AR implementation in real classrooms.

Option B:
Option B is incorrect because it groups B and C and treats both as correct. While B accurately describes AR, C falsely claims that the technologies have no educational relevance, contradicting current practice.

Option C:
Option C is incorrect because it combines A, C and D, thereby accepting C. Although A and D are true, C undermines the educational value of VR and AR, so the combination cannot be accepted.

Option D:
Option D is correct because it gathers the three true statements and sets aside C, which is inconsistent with the growing use of VR and AR in educational contexts.
