Domain 3- Post Implementation Reviews

Question 1

postimplementation review

Answer 1

Following implementation, a cost-benefit analysis or return on investment (ROI) should be re-performed to verify that the original business case benefits are delivered.

Question 2

Parallel Operation

Answer 2

This is the safest form of system conversion testing because, if the new system fails, the old system is still available for production use.

Question 3

postimplementation review of an enterprise resource management system

Answer 3

Reviewing access control configuration would be the first task performed to determine whether security has been appropriately mapped in the system.

Question 4

release management software

Answer 4

Automated release management software can prevent unauthorized changes by moving code into production without any manual intervention.- Library Control Software

Question 5

primary objective of a postimplementation review.

Answer 5

Ensuring that the project meets the intended business requirements

Question 6

hash total

Answer 6

The hash total will only validate the data integrity at a batch level rather than at a transaction level.

Question 7

post-project review vs. post implementation review

Answer 7

Verifying that controls are working should be covered during the acceptance test phase and possibly, again in the postimplementation review. The post-project review will focus on project-related issues

Question 8

Prototyping for large environments

Answer 8

Prototyping may reduce development failure, but a large environment will usually require a phased approach.

Question 9

Phased approach

Answer 9

When developing a large and complex IT infrastructure, a good practice is to use a phased approach to fit the entire system together. This will provide greater assurance of quality results.

Question 10

UAT

Answer 10

When developing a large and complex IT infrastructure, a good practice is to use a phased approach to fit the entire system together. This will provide greater assurance of quality results- THIS HAPPENS BEFORE IMPLEMENTATION

Question 11

White Box Testing

Answer 11

White box testing is used to assess the effectiveness of program logic.

Question 12

Beta Testing

Answer 12

Beta testing follows alpha testing and involves real-world exposure with external user involvement. Beta testing is the last stage of testing and involves sending the beta version of the product to independent beta test sites or offering it free to interested users.

Question 13

Regression Testing

Answer 13

is used to determine whether system changes have introduced new errors to existing functionality. Test data can be used for this

Question 14

Alpha testing

Answer 14

performed only by users within the organization developing the software. Alpha testing generally involves a software version that does not contain all the features of the final product and may be a simulated test.

Question 15

Data Integrity Controls

Answer 15

FIRST Review the data flow diagram.

Question 16

Program output testing

Answer 16

End users perform- A user can test program output by checking the program input and comparing it with the system output
