UGC NET Questions (Paper – 1)

Statements A, B and C correctly distinguish LAN, WAN and MAN by their geographical coverage. LANs serve limited areas like buildings, WANs can span entire countries or continents, and MANs typically cover metropolitan regions. Statement D is false because LANs can be implemented using wired, wireless or mixed technologies. Thus, the combination that includes A, B and C but excludes D is the correct answer.

Option A:
Option A is incorrect because it mentions only A and B as correct and omits C. While A and B are true, statement C is also correct in associating MAN with city-wide networks. Leaving out a true statement means this option does not present the full set of correct statements.

Option B:
Option B is correct because it brings together A, B and C, all of which are accurate descriptions of common network types. It rightly excludes D, which wrongly claims that LANs must always be wireless. Therefore this option aligns with standard ICT classifications of networks by scope.

Option C:
Option C is incorrect because it includes D alongside B and C. Although B and C are true, D is false because LANs may be wired, wireless or a combination. Including a false statement invalidates the combination.

Option D:
Option D is incorrect because it assumes all four statements are correct. Statement D misrepresents the nature of LAN technologies and should not be included among correct statements. A valid answer must exclude that incorrect statement.

Statements A, B, C and D correctly describe governance needs of multi-campus universities. A is true because campus heads require defined authority. B is true as common regulations maintain parity of standards. C is true since quality processes must apply to all locations. D is true because coordinated communication and data sharing are essential for coherent functioning. E and F are false because campuses cannot operate in isolation and multi-campus structures demand deliberate planning and monitoring.

Option A:
Option A is incorrect because it omits D and so underplays the importance of communication and data systems in coordinating multiple campuses.

Option B:
Option B is incorrect because it includes E, which wrongly claims complete independence without reporting, and thus conflicts with central governance.

Option C:
Option C is incorrect because it leaves out A and includes only B, C and D, so it does not explicitly mention the need to delegate authority to campus heads.

Option D:
Option D is correct since it groups A, B, C and D, the four true statements on delegated authority, uniform regulations, quality coverage and coordination systems, while excluding E and F, which deny central oversight and planning.
