ITGSS Certified DevOps Engineer Practice Test

The concept of 'immutability' in DevOps refers to the practice of treating servers and other infrastructure components as immutable, meaning they are not altered or modified after they are deployed. Instead, if an update or change is needed, a new version of the server or application is created and deployed. This approach promotes treating servers as disposable components, allowing for easier management, consistency, and scalability.

By adopting immutability, teams can ensure that every deployment is predictable and consistent with the previous ones, which reduces the risk of configuration drift and other issues arising from changes made to live systems. When a server is deemed to be "disposable," it can be terminated and replaced with a new, up-to-date version whenever updates or changes are required. This aligns perfectly with Agile and DevOps practices, facilitating faster deployment cycles and improving overall efficiency in the software delivery process.

The other choices do not accurately reflect the benefits or the implications of immutability in DevOps. For instance, treating servers as disposable leads to reduced costs in the long run, although it does not inherently increase server costs. Frequent updates can be a part of the process, but the focus on immutability emphasizes the creation of new versions instead. Additionally, immutability
