Which of the following is true about scalability?

i. weak scaling is easier to achieve than strong scaling due to amdahl’s law.

ii. amount of communication among processors usually remains constant or grows slowly.

iii. weak scaling is defined as how the execution time varies with number of processors for fixed problem size per processor.

iv. data dependencies increase with larger problem sizes.

Option (i) is the correct answer to the following question.

Explanation:

Because to achieve the strong scaling then, we have required the Amdahl’s law and the scalability is the weak scaling that is easier to instate than the powerful scaling scalability because of only Amdahl’s law.

So, that's why the following option is correct.

Option (ii) is incorrect because usually, there no communication among the procedures.

Option (iii) is incorrect because the following option is not related to the following statement.

Option (iv) is incorrect because the dependency of the data or information is decreased.

i've had the same problem. i generally just ignore it, as a ton of these "verified answers" are completely wrong.
