Question 2: Post a link to a recent article related to cloud computing. provide a brief synopsis of that article.
Question 3:
Part 1
Your paper should have the following information:
Title Page
Company Information
Business Driver
Provider, Capacity, and Cost
What cloud provider do you propose using (example: AWS, Google, Microsoft Azure, etc.)Identify why you selected this company.What is the estimated size and resource requirements needed?Identify how you determined this.What is the cost?Break down the costs (i.e. software, resources, accounts, etc.)Will the cloud be public, private, community, or hybrid?Describe what this means and why you selected this model.What is the future state of the IT infrastructure?Do you plan on growing the business?Will you need more space? Why? ITSM607 System Test and Verification

6. (2 points) What logic is wrong with this program [not syntax]? Do not tell me this
code fragment violates some Java syntax rules.
/**
* Find index of the Last zero in an array
*
* @return “last index” of 0 in array x;
* or return a -1 if absent (none)
* Note the “last index” is the index of
* the “rightmost” entry
**/
Procedure int LastZero (int[] x)
{
Count = 1;
for (int i = x.length; i > 0; i–)
{
if (x[i] == 0)
{
return count;
}
}
return -1;
}
// test: x = [0, 2, -5, 3]; Expected = 0
7. (2 points) What logic is wrong with this program [not syntax]?
/**

*/
Procedure int CountZero (int[] x)

int count = 0;

if (x[i] => 0)
{
count++;
}
}
return i;
}
// test: x = [0, -2, -1, 3]; Expected = 1

9. Input space partitioning is the practice of dividing the input space according to logical partitions
of the data (True / False) =1 point
10. An input domain model (IDM) represents the input space of the system under test in an abstract
way (True / False). =1 point
11. Under the Input Domain Modeling technique when dividing up input data to create tests of your
program you normally do not specify data characteristics (True / False) =1 point
12. All of the acronyms ACoC, ECC, PWC, TWC, BCC, and MBCC, refer to the same combinations of
input blocks we can choose from when selecting test data (True / False). =1 point
13. Test execution refers to the automation that dynamically runs tests on the software and records
the results (True / False ) =1 point
14. Test evaluation is the process of partitioning the test data. (True or False) =1 point
15. (2 points) What is an executable test script?

18. Refactoring refers to the changing and hopefully improving the structure of existing code
without changing its behavior (True / False) =1 point
19. Model-Driven Test Design makes testing easier because it raises the level of test Abstraction to
include Design Abstraction and Implementation Asbtraction. (True / False) = 1 point
