Project Management Professional (PMP) Exam Practice – Question1381

Activity A has a duration of three days and begins on the morning of Monday the 4th. The successor activity, B, has a finish-to-start relationship with A. The finish-to-start relationship has three days of lag, and activity B has a duration of four days. Sunday is a non
workday. Such data can help to determine______________


A. The total duration of both activities is 8 days
B. Calendar time between the start of A to the finish of B is 11 days
C. The finish date of B is Wednesday the 13th
D. Calendar time between the start of A to the finish of B is 14 days

Correct Answer: B

Explanation:

Explanation:
The duration of A, which is three, is added to the duration of B, which is four, for a total of seven. The three days between the activities is lag and not duration. The lag is a constraint and must be taken into account as part of the network calculations, but it does

not consume resources. The total time by the calendar is 11 days as counted from the morning of Monday the 4th. The lag occurs over Thursday, Friday, and Saturday. Sunday is a non workday, so activity B does not start until Monday the 11th. Therefore, the
calendar time is 11 days, and activity B ends on Thursday the 14th.
