Which of the following provides the BEST approach for deploying multiple new firewalls into an IaaS cloud environment with minimal errors?

Manual deployment configuration is prone to human error, inconsistent, and time-consuming when deploying multiple firewalls in a cloud environment.

Cloud provider installation typically refers to the cloud provider setting up the underlying infrastructure, not the specific automated deployment and configuration of customer-specific firewall instances.

Automated and orchestrated deployment uses Infrastructure as Code (IaC) principles to define, provision, and configure multiple firewalls consistently across the IaaS environment. This approach significantly reduces human error, ensures standardization, and provides scalability and repeatability for complex deployments.

While cloning can replicate a base firewall configuration, it does not address the orchestration and unique integration needs for deploying multiple instances with distinct network settings or policies within an IaaS environment.
