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:
A is the best answer. Implementing and using a test environment for patches, updates, maintenance, etc is a best practice and strongly encouraged as by Network+.
B is not the best answer since having an network Access Control List on a switch to limit access would not prevent or mitigate the problem of a production server being corrupted/inoperative due to improper maintenance. Limiting access to a resource may be a component of what happens during a maintenance window, however.
C is not the best answer since an IPS will not prevent or mitigate the problem of a production server being corrupted/inoperative due to improper maintenance.
D is not the best answer since moving the software team’s workstations should not prevent or mitigate the problem of a production server being corrupted/inoperative due to improper maintenance.
