DOL Automation Strategy 5

Question 1

A DevOps leader is evaluating whether to build or buy an automation platform. Which factor most strongly favors building in-house?

Accepted Answer

Highly unique internal workflows that no commercial tool adequately addresses

Answer

Build decisions are justified when the required capability is a true competitive differentiator or so unique that adapting commercial tools would cost more than building.

Question 2

Which technique enables progressive delivery by automatically routing a small percentage of traffic to a new version while monitoring for errors?

Accepted Answer

Canary release with automated rollback triggers

Answer

Canary releases expose a small traffic slice to the new version and use automated health checks to trigger rollback if error rates or latency exceed thresholds.

Question 3

When automating multi-cloud deployments, which approach best ensures portability and avoids vendor lock-in?

Accepted Answer

Adopting cloud-agnostic IaC tools like Terraform with provider-abstracted modules

Answer

Cloud-agnostic IaC tools abstract provider-specific APIs behind a common language, enabling the same automation to target multiple clouds with minimal changes.

Question 4

What is the primary purpose of a deployment pipeline 'promotion gate' between staging and production?

Accepted Answer

To enforce automated quality, security, and performance criteria before an artifact advances to the next environment

Answer

Promotion gates automate the go/no-go decision by validating predefined criteria, preventing defective or non-compliant artifacts from advancing to production.

Question 5

A DevOps leader wants to automate post-incident remediation steps. Which artifact should the automation consume to ensure consistency?

Accepted Answer

Structured runbooks encoded as executable scripts or workflow definitions

Answer

Structured, executable runbooks encode remediation steps in a machine-readable format, enabling automation to execute them reliably and consistently without human interpretation.
