Which of the following risks could IT management be mitigating by removing an all-in-one device?

A.
Continuity of operations

B.
Input validation

C.
Single point of failure

D.
Single sign on

Explanation:
The major disadvantage of combining everything into one, although you do this to save costs, is to include a potential single point of failure and the reliance/
dependence on a single vendor.
Incorrect Answers:
A: Continuity of operation plan refers to policies, processes and methods that an organization has to follow to minimize the impact of failure of the key components
needed for operations.
B: Input validation refers to secure coding and removing an all-in-one device is not mitigating an input validation problem. Rather you are mitigating a single point of
failure problem.
D: Single sign-on is an authentication issue.
