Some of the content appears nowhere in the PMBOK so I was looking for some insight to some odd questions.

Please list the question number in the subject when posting.

  1. ________ is typically not referred to as a buffer type in critical chain project management.
 
  Resource buffer
  Free buffer
  Feeding buffer
  Project buffer

 

 

Correct answer was Free Buffer, I answered Resource Buffer since I had not seen that term anywhere.

Only Feeding and Project are mentioned in the PMBOK, How is someone supposed to know which of the unknown buffers is the correct answer?

71.

A project sponsor requested earned value data on two concurrent projects from the project managers. Both projects are regarded as equally important and strategically beneficial and have been finished by over 80%. He received the following information:

Project A:
   PV: $1,800,000
   EV: $2,300,000
   AC: $2,100,000

Project B:
   PV: $2,000,000
   EV: $1,500,000
   AC: $1,600,000

The sponsor considers to shift some resources from project A to project B to speed up the second project which is currently behind schedule.

What is the most likely outcome of such a measure?
 

 

Changing team assignments during late course of a project typically increases cost efficiency.

  Changing team assignments during late course of a project typically increases time efficiency.
 

According to the law of diminishing returns, the consolidated cost variance of the two projects will decrease.

 

According to the law of diminishing returns, the consolidated cost variance of the two projects will increase.

answer was C but I cannot find supporting material that states cost variance would DECREASE from changing team assignments, seems counter intuitive at the least.

The link provided in the answer key yielded a 404 message

Where in the world does this come from?
63. What is the meaning of a concept called the "Journey to Abilene"?
 
certainly not in the PMBOK

I feel like I am prepared for the PMP exam but questions like this seem crazy. Are there really questions like this on the test that have no link at all to the PMBOK?

apparently any concept in the PM universe is fair game for the PMP exam.

It almost seems like they are trying to guarantee that noone could get a 100%

23. A prime contractor in a customer project under CPFF contract has run into unexpected technical problems. Fixing them will require a lot of additional work to be done.

The company made a decision to book more staff and equipment from their subcontractors in order to adhere to the agreed timeline. The customer agreed to this decision.

What will most likely happen?
 
  The contractor‘s indirect costs will increase and the customer‘s payment for them will increase, too.
  The contractor‘s indirect costs will increase, but the customer‘s payment for them will not increase.
  The contractor‘s indirect costs will not increase, but the customer‘s payment for them will.
  Both the contractor's indirect costs and the customer‘s payment for them will not increase.

Cost Plus Fixed Fee contract = CPFF

if the contractor ran into problems and booked more staff and equipment,

in that case the indirect costs go up and so does the customer's payment for them. (cost plus)

But the key lists D as the correct Answer.  can someone explain?

this is a trick question about indirect costs.

Indirect costs are not attributable to a project so they are not affected.

 

22. You are assigned as the project manager to a project which is executed for a customer under FP contract. Your customer informed you this morning that they insist on certain "refinements" of the project scope.

You agree that the requested actions make really sense to the project, but believe that they constitute a major change increasing the project scope. What should you do next?

B) Perform earned value analysis to assess the current status of the project and get all the numbers you need to communicate the case to the change control board which then will have to make the best decision regarding the customer request.

C) Check the contract, the project charter, the scope statement and other documents related to the project and the contract. Implement ADR (alternative dispute resolution) procedures if the conflict cannot be resolved otherwise.

 

I put B but the key says the answer is C

ADR seems extreme here.  Submitting a change to the CCB seems like the best "next" thing to do.  Earned value analysis, though, does not seem to belong so maybe that should disqualify B.

Anyway, A CR to the CCB seems like the answer.

Your project is executed with a globally spread virtual team. The project progress has been found to be too slow. Which measure is most likely to immediately speed up the project?

A) Technical training for all team members

B) Daily phone conferences and detailed reporting

C) A team meeting at a location convenient to all team members

D) Collocation of team members at a suitable place

 

The answer was D.

This seems to be quite a break from reality.  Collocation is not a feasible option for the typical global virtual team.  It is really frustrating when the correct PMP answer is not something that can happen in the real world.

 

 

Start dates in the following network logic diagram are defined as early morning, finish dates are evening.

If tasks are scheduled to begin at early start date, what is true?

A) Activity B has a free float of 10 d.

B) Activity B has a total float of 10 d.

 

Answer keys says B is correct.  but isnt A also correct?

 

 

I have received your blog shared discussions to answer for practice test. So, we have to read free questions from this custom essay writing article. That included answers in the last of the page with explanation.
