Critical Path — Quiz

Test your understanding of critical path with 5 practice questions.

Practice Questions

Question 1

In CPM analysis, an activity for which $EF = LF$ always has which characteristic?

Question 2

Consider the project network where Activity $A$ (3 days) precedes both $B$ (4 days) and $C$ (6 days) in parallel, and both $B$ and $C$ precede Activity $D$ (5 days). Which sequence constitutes the critical path and what is the project duration?

Question 3

For the network described above, what is the total float of Activity $B$?

Question 4

In the same network, what is the free float of Activity $C$?

Question 5

In a backward pass, if Activity $E$ has duration 5 days and its only successor $F$ has latest start $LS_F = 10$ days, what are $LF_E$ and $LS_E$?
