Hello, I am new to this forum!

And I know I would be visiting here often!

I am taking a PMP preparation course through a university professional development program. I have to write exam in next few days. The exam is open, meaning I already have the questions in my hand.

I came across few tricky ones, and I can figure out the answer.

(BTW, English is not my first language, so I wonder whether the limitation is due to the language factor).

Please help:

Q1) What is a limitation of PMBOK guide?

Two answer options are: ITS BREADTH and ITS DEPTH.

(I have elimited the other two answer options)

The limitation of the guide is that it covers a very wide range, without much depth. So in my head both of these options are limitations, but I must chose one. What would the correct answer be?

Q2) What is a disadvantage of using a phased approach to plan and control your project?

a) It may be time-consuming

b) It results in a 'pay me more later' condition

c) It increases uncertainty

d) It reduces communication

I guess I have eliniated Dm but then I can't see a clear answer option either...

Q3) How should you express project assumptions?

a) Document them f or future reference

b) As part of acceptance criteria

(I have eliminated the other two).

They both seem right to me... I guess it shows how unprepared I am... darn

Q4)

 How do you find a project's critical path

a) By scheduling only critical resources

b) By performing a forward abd backward passes

c) By using crashing

d) By identifying activities with float

I guess C is out. 

D is probaby wrong, but if you identify activities with float, then you can ID critical path by finding path with no float...

B is probably wrong, because you do that do calcupate float... but again it goes back to D

So I guess the answer is A? But don't you have to schedule all activities in order to find the critical path? Maybe I need to sleep and re-think these questions...

Q5) Which of the following choices is an importanbt element of Validate Scope?

a) Inspection

b) Work performance information

(I have eliminated other two options. Inspection is a tool of VS and Work Performance Information is an output of VS. Then aren't both important elements?)

As I go over this exam's questions, I am surprised to find myself to struggle with more basic concept questions (the ones that were supposed to be easier ones) then more 'complex' ones. Are the actual exam questions this tricky? It almost feels like trap questions to me.

Thank you in advance for your help!
