Which of the following would be the best reason for separating the test and development environments?

A.
To restrict access to systems under test.

B.
To control the stability of the test environment.

C.
To segregate user and development staff.

D.
To secure access to systems under development.

Explanation:
You should always separate test and development environments.
When testing a system, you need to isolate the system to ensure the test system is controlled and stable. This
will ensure the system is tested in a realistic environment that mirrors the live environment as closely as
possible.
Access control methods can be used to easily separate the test and development environments.
Incorrect Answers:
A: Restricting access to systems under test is not the best reason for separating the test and development
environments. Preventing instability in a development environment from affecting the test environment is a
better answer.
C: Segregate user and development staff is not the best reason for separating the test and development
environments.
D: Securing access to systems under development is not the best reason for separating the test and
development environments. Securing access to systems under development would not be achieved by
separating the test and development environments.
