A Junior DevOps engineer has just joined your organization. He is exploring ways to automate the existing process of infrastructure provisioning and management using code. As his tech lead, what suggestions in general would you like to provide him? -Use any technique that would ensure no human interference and should be automating resources. -Explore the requirements and utilize the correct IaC tools that check all the required boxes. -Use any IaC tool out there as they are all the same. -Run a POC using a single tool and stick to it for all tasks -Utilize bash scripting to codify infrastructure and use it to define, provision, configure, update and destroy infrastructure resources.

Your company has recently been contracted to oversee a business transformation project for a large bank. This project requires a lot of the legacy banking applications to be migrated to several different cloud platforms - AWS, Azure, GCP to name a few. The solution architects of your team have decided to go with Terraform as their choice for the infrastructure provisioning. Why do you think they went with this choice? -Terraform is vendor agnostic and supports multiple providers which is a good fit for this project. -Terraform is the ideal choice for Configuration Management as well as Provisioning -Disagree with the choice - should have used CloudFormation -They just went with their gut feeling

Terraform is vendor agnostic and supports multiple providers which is a good fit for this project.

What allows Terraform to make use of a declarative approach? -Terraform uses multiple providers that supports all major cloud providers -Terraform uses JSON instead of YAML -Terraform uses modules unlike Ansible -Terraform makes use of a state file

Terraform makes use of a state file
