In this movie, we'll close out the review of the exam practice questions located within your work files. This includes the final 5 questions on the Time Knowledge Area, questions 41-45. Question 41 tests your knowledge of the estimate ranges. It states, what is the estimate range of a definite estimate? Is it A: Negative 5 percent through 10 percent. B: Negative 15 percent to 15 percent. C: Negative 25 percent to 75 percent or D: Negative 10 percent to 25 percent. To answer this you need to remember the ranges and their names, the names however give you a clue. For example this one is asking for a definite estimate letting you know that the estimate is within a smaller range. Here's the snapshot of the table of estimates and looking toward the bottom you'll see definite estimate which has the range of negative 5 percent to 10 percent making A the correct choice. Question 42 states all of the following are a type of project schedule Network Diagram except? A: Presidents Diagramming Method. B: Activity on Node. C: Schedule Comparison Bar Chart or D: Arrow Diagramming Method. We review the Network Diagram Types during the activity sequencing process. There were two primary Network Diagrams, Presidents Diagram Method and Arrow Diagramming Method. As you might recall each had another name that they went by. Presidents Diagramming Method is also known as Activity on Node and Arrow Diagramming Method is also known as Activity on Arrow, that leaves Schedule Comparison Bar Chart. Schedule Comparison Bar Chart does exist but it's a tool and technique of the Schedule Control Process. Let's move onto 43 which says, all of the following involves Schedule Compression Techniques except? A: Moving an activity to a current parallel with another activity. B: Removing an insignificant feature from the product. C: Crashing the schedule. Or D: Adding an additional resource to an activity. Schedule Compression Technique is a tool and technique of the Schedule Development Process. A describes Fast Tracking, where multiple activities occur in parallel verses in sequence as a way to complete the activities quicker. B involves reducing the Scope of the Project which is a big no no and C is removed because crashing is Schedule Compression Technique that usually involves adding resources to complete the activities quicker. And that also describes C as a removal which states that additional resources are added to an activity and that only leaves B as the correct answer and I'll say it again, that reducing scope is not the acceptable approach to meeting deadlines. Question 44 states, the amount of time that a schedule activity can be delayed without delaying the early start date of any immediate successor activity within the Network Path is called? A: a total float. B: Free Float. C: Zero Float or D: Project Float. The correct is B, Free Float. For clarification and review a Total Float reverts to the amount of time that is a schedule activity can be delayed without delaying the project. Project Float is the amount of time that the overall project can be delayed without delaying the completion date provided by the customer. And Zero Float means that Zero Flexibility within the schedule exists which would mean that the activities with Zero Float fall on the Critical Path. And the final question, number 45 asks for the late finish of activity F within the Network Diagram provided. The answers are A: 10. B: 7. C: 12 or D: 13. To calculate finish we would use a backward pass meaning that we would work our way from the end to the start. We would first need to calculate the Critical Path to determine the longest path of the Network Diagram. The Critical Path is 13. The Activities that are directly tied to the end which include Activity D and F will have a late finish of the length of the Critical Path which is 13. Therefore the correct choice is D. And that concludes our review of practice exam questions 41 through 45.
