ICT Cloud Computing and Virtualization 5

Question 1

What is 'Infrastructure as Code' (IaC) in the context of cloud computing?

Accepted Answer

Managing and provisioning cloud infrastructure through machine-readable configuration files

Answer

IaC (e.g., Terraform, CloudFormation) lets you define and version infrastructure in code for repeatable, automated deployments.

Question 2

Which disaster recovery metric defines the maximum acceptable amount of data loss measured in time?

Accepted Answer

RPO (Recovery Point Objective)

Answer

RPO specifies how far back in time data can be lost; if RPO is 1 hour, backups must occur at least hourly.

Question 3

In Kubernetes, what is a 'Pod'?

Accepted Answer

The smallest deployable unit, containing one or more containers sharing network and storage

Answer

A Pod is Kubernetes' atomic unit of deployment, wrapping one or more tightly coupled containers.

Question 4

What does 'serverless computing' mean?

Accepted Answer

A model where developers deploy functions and the cloud provider manages all server provisioning and scaling

Answer

Serverless (e.g., AWS Lambda) abstracts server management; developers write functions and pay only for execution time.

Question 5

Which cloud security concept follows the principle of 'never trust, always verify' regardless of network location?

Accepted Answer

Zero Trust Architecture

Answer

Zero Trust assumes no implicit trust based on network location and requires continuous verification of every user and device.
