A system administrator has been tasked to ensure that the software team is not affecting the production software when developing enhancements. The software
that is being updated is on a very short SDLC and enhancements must be developed rapidly. These enhancements must be approved before being deployed.
Which of the following will mitigate production outages before the enhancements are deployed?

A.
Implement an environment to test the enhancements.

B.
Implement ACLs that only allow management access to the enhancements.

C.
Deploy an IPS on the production network.

D.
Move the software team’s workstations to the DMZ.

Explanation:
Environments are controlled areas where systems developers can build, distribute, install, configure, test, and execute systems that move through the Software
Development Life Cycle (SDLC). The enhancements can be deployed and tested in a test environment before they are installed in the production environment.
