CSI CSI Change Management & Deployment 2

Question 1

Which deployment pattern gradually shifts traffic from an old version to a new version in incremental percentages?

Accepted Answer

Rolling deployment

Answer

A rolling deployment incrementally replaces old instances with new ones, limiting blast radius while gradually migrating all traffic.

Question 2

A post-implementation review (PIR) after a major integration deployment should focus on:

Accepted Answer

Evaluating what went well, what failed, and lessons learned to improve future deployments

Answer

A PIR captures lessons learned from the deployment to continuously improve processes for future integration projects.

Question 3

Continuous Delivery (CD) in a system integration context means:

Accepted Answer

Keeping software in a deployable state so releases can happen on demand with minimal manual steps

Answer

Continuous Delivery ensures the codebase is always in a releasable state, with automated pipelines that require only a manual approval gate for production.

Question 4

What is 'infrastructure as code' (IaC) and why is it valuable in CSI deployments?

Accepted Answer

Managing and provisioning infrastructure through machine-readable configuration files, enabling repeatable and auditable deployments

Answer

IaC enables version-controlled, repeatable infrastructure provisioning, reducing human error and ensuring consistent environments across dev, test, and production.

Question 5

A 'feature flag' (feature toggle) allows a system integrator to:

Accepted Answer

Enable or disable functionality at runtime without deploying new code

Answer

Feature flags decouple deployment from release, allowing new integration features to be deployed but kept hidden until they are ready to activate.
