Question
Which of the following conditions is the most appropriate for changing and adding a program to a system that is currently live?a) After finishing changes to the program, perform test using the same conditions as the production environment, before determining whether to go live.
b) When adding a program, changes are made directly to the live system by judging the right time to make the changes.
c) If the system is live, shutdown all system first before swiftly adding the program, since it is not possible to test the program that will be added.
d) It is sufficient to test only the portion that is added, to confirm that the added program operates normally.
Explanation / Answer
The answer should be condition a) "After finishing changes to the program, perform test using the same conditions as the production environment, before determining whether to go live". This is the most appropriate answer from all the choices given. I assume this condition means that you add the program to a copy of the live system and then perform thorough testing of your program before making the modified system live. This is the correct process to go through because this ensures the integrity of the live system by testing potential changes to the system for bugs before submitting said changes. If there were bugs in your program/code, then at least the live system is still fine while you go through the potentially lengthy process of debugging code. Choice b is not appropriate because you are making changes to the live system before you tested your code. There is a high probability that you will break your live system and potentially lose irrecoverable data. Choice c is not appropriate for the same reason as choice b, but in addition, now your system will undergo additional downtime from you shutting it down to perform the system upgrade. Choice d is not appropriate because the portion of the system you changed might be linked to other parts of the system. It is important to test the system as a whole as well as the parts that you have modified to ensure that the system still behaviors as expected.
