Exam 350-201 topic 1 question 59 discussion

One of the principles of Infrastructure as Code (IaC) is that system maintenance tasks, which were traditionally performed manually, are now automated and managed bysoftware systems567. This allows for consistent, repeatable routines for provisioning and changing systems and their configuration, with changes made to definitions and then rolled out to systems through unattended processes that include thorough validation7.

Sure A

The correct answer is B. Comprehensive initial designs support robust systems. Infrastructure as Code (IaC) is a methodology that involves managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. One of the key principles of IaC is that comprehensive initial designs support robust systems. This means that IaC should include a well-designed architecture and a comprehensive set of templates and scripts to ensure consistency, repeatability, and predictability in system deployment and maintenance. By having a strong initial design, it is easier to build and maintain a reliable infrastructure, as it reduces the risk of errors and inconsistencies that could lead to downtime and other issues.

Infrastructure as code (IaC) is a software-based IT methodology for codifying and maintaining IT infrastructure

I prefer C. "to ensure repeatable routines"

IaC has popularized the concept of immutable infrastructure. In other words, rather than continuously updating and modifying existing infrastructure, the infrastructure is not reconfigured or updated every time there is a change in the application. Instead, it is replaced with a new one, built from a common image with the necessary changes in place. https://www.cisco.com/c/en/us/solutions/cloud/what-is-iac.html#~key-q-a

System maintenance is delegated to software systems
