UGC NET Questions (Paper – 1)

Statements A and C correctly describe strong password characteristics and the value of two-factor authentication, whereas B and D promote insecure behaviour. Reusing a single password across many services increases the impact of any one compromise. Similarly, displaying passwords openly on a monitor invites misuse by anyone nearby. Thus, the only acceptable combination is the one that includes A and C but excludes B and D.

Option A:
Option A is incorrect because it chooses only A and leaves out C. While A is true, ignoring the important role of two-factor authentication underestimates modern security practices that combine something you know with something you have or are.

Option B:
Option B is incorrect because it selects C only and omits A. Two-factor authentication is indeed valuable, but strong password construction remains a basic requirement for protecting accounts. This option therefore does not include all correct statements.

Option C:
Option C is correct because it recognises that both strong passwords and multi-factor authentication work together to enhance security. It explicitly rejects the risky practices of password reuse and visible notes, which are described in B and D.

Option D:
Option D is incorrect because it accepts all four statements, including B and D. Since those two statements contradict fundamental security guidelines, this combination cannot be considered correct.
