UGC NET Questions (Paper – 1)

Statements A, B and D are correct descriptions of intranet and extranet, whereas statement C is false. Intranets are typically restricted to members of an organisation and require authentication, not open public access. Extranets deliberately allow selected outsiders in, under controlled conditions, and both networks often use browsers and secure protocols. So the combination A, B and D only is correct.

Option A:
Option A is incorrect because it lists only A and B as correct, omitting D. While A and B are true, statement D is also accurate in noting that web browsers and secure connections can be used to access both intranet and extranet. Excluding D makes the option incomplete.

Option B:
Option B is incorrect because it groups A, B and C as correct and thereby accepts C. Statement C misrepresents intranets as publicly open, which contradicts their private nature. Including this false statement invalidates the combination.

Option C:
Option C is correct because it selects A, B and D, all of which align with common networking practice. It recognises the private and extended nature of intranet and extranet, as well as typical access methods, while properly rejecting the incorrect claim in C.

Option D:
Option D is incorrect because it includes B, C and D as correct, accepting C. Although B and D are true, C is not, and a correct option cannot mix them.
