Question 1

What is the primary advantage of using a 'Python-based IaC' tool like Pulumi over domain-specific...

Answer

It allows developers to use standard programming constructs (loops, classes, functions) and existing Python libraries for infrastructure logic and testing

Question 2

In a CI/CD pipeline, what is the 'Shift Left' security principle?

Answer

Integrating security testing (SAST/DAST) early in the development lifecycle to catch vulnerabilities before code is merged

Question 3

When containerizing a Python application, why is it best practice to use a 'Multi-stage Build' in...

Answer

To separate the build environment (compilers, build-tools) from the runtime environment, resulting in a significantly smaller and more secure final image

Question 4

What is the role of a 'Sidecar Container' in a Kubernetes Pod for a Python microservice?

Answer

A secondary container that runs alongside the main app to handle cross-cutting concerns like logging, proxying (Envoy), or configuration syncing

Question 5

How does 'GitOps' (using tools like ArgoCD or Flux) differ from traditional CI/CD push deployments?

Answer

In GitOps, the cluster 'pulls' the desired state from Git and automatically reconciles differences, ensuring Git remains the single source of truth

Question 6

Which Python library is widely used for automating remote systems administration and configuratio...

Answer

Question 7

What is a 'Helm Chart' in the context of Kubernetes?

Answer

A package manager for Kubernetes that uses templates to define, install, and upgrade complex Kubernetes applications

Question 8

What is 'Immutable Infrastructure'?

Answer

A practice where servers are never modified after deployment; if a change is needed, new servers are built from a common image and the old ones are replaced

Question 9

In Prometheus monitoring, what is the difference between a 'Counter' and a 'Gauge' metric?

Answer

A Counter only increases (e.g., total requests); a Gauge can go up and down (e.g., current memory usage)

Question 10

What is 'Canary Releasing'?

Answer

Rolling out a new version of an app to a small subset of users to test stability and performance before deploying to the entire population
