Comprehensive and Detailed Explanation From Exact Extract:
Automation is the primary method of reducing toil in SRE. The Google Site Reliability Engineering Book, Chapter "Eliminating Toil," states:
"Automation is the most effective tool for reducing toil. Any recurring, manual, automatable task should be automated to prevent it from consuming engineering time." Automated release systems directly eliminate toil by:
* Removing manual deployment steps
* Removing repeated, error-prone human processes
* Increasing reliability and consistency
* Freeing engineers for high-value project work
The SRE Workbook reinforces this:
"CI/CD pipelines and release automation remove significant operational toil by replacing manual processes with repeatable, reliable automation." Why the other answers are incorrect:
* B AI is not required for toil reduction.
* C Meeting travel is not an SRE toil concern.
* D Incorrect; automation dramatically reduces long-term toil, even though initial setup requires effort.
Thus, A is the correct answer.
