Final answer:
Automated configuration minimizes human error in server configuration by using tools that ensure consistent provisioning across all servers, unlike manual or hybrid approaches which are susceptible to human mistakes.The correct option is B.
Step-by-step explanation:
To minimize human error in maintaining configuration consistency across a scaled-up server infrastructure, the best approach is automated configuration. This often involves the use of configuration management tools like Ansible, Puppet, Chef, or Terraform. These tools ensure that all servers are provisioned with the exact same configuration, reduce manual intervention, and as a result, decrease the likelihood of human errors.
Manual configuration is prone to errors because it relies on humans repeating tasks accurately across many servers. A hybrid configuration could mean a mix of manual and automated steps which still leaves room for error. Random configuration is not a systematic approach and therefore introduces the highest potential for inconsistency and error.
Therefore, the answer to the question: 'Which approach would introduce the least human error in maintaining configuration consistency across all servers?' is b. Automated configuration.
