Discuss PMI PMI-SP Exam Topic 3 Question 37

You work as a project manager for BlueWell Inc. You must communicate on a regular basis with all of

your project stakeholders. In your

project, you have 755 stakeholders. How many communication channels exist in the project?

A284,635

B570,025

C569,270

D755

Suggested Answer: A

The number of communication channels describes the number of opportunities for

stakeholders to communicate amongst themselves and for

communication to be broken down. To find the number of communication channels, you can use the

formula of N(N-1)/2 where N represents

the number of stakeholders.

Total number of communication channels = N(N-1)/2

= 755(755-1)/2

= 284,635

Answer option D is incorrect. This is the number of stakeholders.

Answer option C is incorrect. 569,270 is not a valid calculation of this formula.

Answer option B is incorrect. 570,025 is not a valid calculation of this formula.

Wait, how did they get that number? Seems off.

I vaguely remember that the number of stakeholders can lead to exponential growth in communication channels, so I’m leaning towards the highest option.

I feel like the answer is going to be one of the bigger numbers, but I’m not confident in my math skills right now.

Tamar 1 year ago

I remember something about the formula for communication channels being n(n-1)/2, but I'm not entirely sure if I applied it correctly.

Wenona 1 year ago

I think I practiced a similar question, and it was definitely a large number, but I can't recall the exact calculation.

Ninja 0 and Ninja Stars don't sound like real HPE tools to me, so I'll rule those out. Time to focus on the more likely options.

Okay, let me think this through. The loop iterates over the tokens 'a', 'b', and 'c', and for each one, it uses echo -n to print the token without a newline. I think the output will be just 'abc'.

Okay, I think I've got a strategy here. I'll focus on the key details and try to identify the best approach.

Gene 1 year ago

Okay, I think I've got a good handle on the key relevant costs here. Now I just need to crunch the numbers and see which of the answer options matches my calculation.

Hmm, I'm a bit unsure about this one. The options don't seem to clearly match the concept of advance ship notice. I'll have to think it through and try to eliminate the options that don't fit.
