Interview Questions & Answers on ANSIBLE

Q1. What is Ansible and how does it work?

Answers: Ansible is an open source automation tool for managing configuration, deployment and development. It uses notifications to verify the configuration process and execute remote control tasks via SSH, making property management easy and efficient.

Q2.What are the main features of Ansible?

Answer: The main components of Ansible are:

- Ansible Playbooks: Playbooks are written in YAML and define tasks to be performed on the remote host.

- Ansible Modules: Modules are reusable scripts that perform specific tasks such as developing packages, managing services, or configuring files.

- Ansible Inventory: Inventory files list hosts or groups of hosts managed by Ansible and allow you to group hosts by different criteria.

- Role redundancy: A role is a way to logically organize and reuse functions, variables, and data.

Q3. How is Ansible different from other configuration management tools?

Answer: Ansible is agentless, meaning it does not require any software to be installed on the controller. It uses SSH and Python to perform remote operations, making it lightweight and easy to setup. Ansible also ensures rapid adoption and efficiency by emphasizing simplicity, readability and ease of use.

Q4. How is Ansible used for configuration management?

Answer: Ansible provides manifests to define configuration methods and use models to perform certain tasks. Playbooks are used to define the desired state of the system and Ansible applies the necessary changes to ensure the system conforms to the desired state.

Q5.What is powerlessness in Ansible and why is it important?

Answer: Impotence means that the result is the same no matter how many times the operation is performed. The incompetence in Ansible ensures that running the same playbook multiple times has the same effect as running it once, making it safe and reliable. This tool provides easy and predictable management and reduces the risk of incorrect changes.

Q6. How to use variables in Ansible? What do they mean? Chapter

Answer: Changes to Ansible allow fine tuning for different scenarios. They can be defined in different places such as notifications, workbooks or individual files. Differences can be passed as arguments or stored in external systems such as Ansible Vault to securely store sensitive data.

Q7. How does Ansible integrate with version control?

Answer: Ansible playbooks and configurations can be stored in version control systems such as Git. This integration allows for collaborative development, change tracking and recovery. Ansible can also be integrated with CI/CD pipelines to trigger tasks based on code changes or custom events.

Q8. What is the Ansible Galaxy? How does it help using Ansible?

Answers: Ansible Galaxy is a central repository for sharing and reusing Ansible roles and collections. It provides a community-driven platform where users can publish and explore roles first, simplifying the use of existing solutions and speeding up development and automation.

Q9. How can Ansible be used for cloud planning?

Answer: Ansible has a unique architecture to interact with cloud providers such as AWS, Azure, and Google Cloud. This model enables infrastructure development in the cloud environment by allowing provisioning of cloud resources such as virtual machines, storage and connected devices.

Q10. What are some best practices for using Ansible effectively?

Answer: Here are some of the best practices for using Ansible effectively:

- Organize scripts and roles in a consistent and reusable way.

- Store important files with Ansible Vault
