4. The output of an AND gate with three inputs, A, B, and C, is HIGH when _____________.
- A = 1, B = 1, C = 1
- A = 1, B = 0, C = 1
- A = 1, B = 1, C = 0
- A = 0, B = 0, C = 0
Answer :-
5. If a signal passing through a gate is inhibited by sending a LOW into one of the inputs, and the output is HIGH, the gate is a(n):
- AND
- NAND
- NOR
- OR
Answer :-
6. If a 3-input NOR gate has eight input possibilities, how many of those possibilities will result in a HIGH output?
- 1
- 2
- 7
- 8

7. The primary difference in the GERT results and the results obtained from a PERT or CPM network (apart from the fact that the GERT results reflect a stochastic network) are _____________.
- the Cost Statistics
- the complete time management data
- the normalized time statistics
- the critical tasks on the network
Answer :-
8. Which project management technique has features such as probabilistic branching (stochastic models), network looping (feedback loops), multiple sink nodes (multiple outcomes), and multiple node realization (repeat events)?
- PERT
- GERT
- CPM
- DECISION TREES
Answer :-
9. Q-GERT is a network modelling technique developed to:
- perform data modelling tasks.
- provide superior results to deterministic PERT/CPM models.
- analyse general stochastic networks.
- None of the other given options.
Answer :-
10. In general, the GERT network is not as sensitive to activity time changes as node branching probability changes. Of course if the project activity times are extremely cost sensitive then a slight alteration in an activity time can affect network (project) cost even though the overall network time might not be affected significantly.
- May be or May be Not
- False
- True
- None of the other given options
