PeopleCert DevOps-SRE Exam - Topic 3 Question 74 Discussion

Comprehensive and Detailed Explanation From Exact Extract:

Linear-scaling toil refers to work whose effort increases proportionally to service growth, such as manually provisioning servers or handling capacity expansion. The Google SRE Book, Chapter ''Eliminating Toil,'' explains:

''Toil is work that scales linearly with the size of your service. A core strategy for reducing toil is to introduce automation that breaks the linear relationship.''

Auto-scaling capabilities directly address linear-scaling toil by automating resource allocation based on load or demand. This prevents engineers from repeatedly and manually adjusting infrastructure as usage grows.

The SRE Workbook also emphasizes:

''Infrastructure automation such as auto-scaling removes a major source of linear scaling toil by ensuring that capacity adjusts automatically as services grow.''

Why the other options are incorrect:

A Manual scaling is linear-scaling toil, not a solution.

C Outsourcing development does not reduce operational toil.

D Switching cloud providers alone does not solve toil unless automation is introduced.

Thus, B is the correct answer.
