Question 1

sandbox

Answer 1

The sandbox is an isolated environment that is often used for testing. Security, patches, and critical updates can be tested in a sandbox without touching the system before implementation.

Question 2

staging

Answer 2

The staging environment mimics that of production and allows for an environment to practice deployment. In the event deployment fails in this environment, it can roll back to the test and development environments.

Question 3

production

Answer 3

The production environment is the final stage of the deployment effort. Testing in this environment would be too late, given it is the operational environment.

Question 4

development

Answer 4

The development environment is a place for creation. Requirements are turned into reality in this environment. It is not a complete copy of production, but just the beginning of an application.

Question 5

remediation

Answer 5

When a baseline change is detected in a system, the system is removed from the network to perform remediation techniques. This can include applying updates and correcting code to resolve errors and vulnerabilities.

Question 6

code refactoring

Answer 6

Code refactoring is the process of improving existing code without changing its behavior and adding new requirements.
