1.8 Infrastructure as Code Flashcards
N10-009 Obj 1,8 Summarize evolving use cases for modern network environments. (11 cards)
What is Infrastructure as Code (IaC)?
A method of managing and provisioning infrastructure through machine-readable configuration files instead of manual processes.
Transcript: “Infrastructure as Code… describe it in terms that are best described as code… we can build a configuration file…” (0:01–0:19)
What are the benefits of using Infrastructure as Code?
It enables automation, version control, duplicate deployments, and consistency across environments.
Transcript: “We can build out infrastructure as code configurations… redeploy… exact duplicate… flexibility…” (0:47–1:23)
What kind of details can be included in an IaC configuration file?
Hostnames, CPU type, IP addressing, network configs, and required applications.
Transcript: “Include other details… type of CPU, how much network configurations, IP addressing…” (1:47–1:59)
What is a playbook in the context of automation?
A predefined set of steps to respond to specific events like breaches or malware, enabling consistent automated responses.
Transcript: “A playbook is a series of steps you would follow… investigate a data breach… recover from ransomware…” (2:13–2:30)
What is a SOAR platform and how does it related to playbooks?
SOAR stands for Security, Orchestration, Automation, and Response. It centralizes playbook management and security operations.
Transcript: “Playbooks are commonly implemented into SOAR platforms… management console… centralized deployment…” (3:05–3:28)
How does IaC help prevent configuration drift and enforce compliance?
By using consistent configuration files to deploy identical systems, avoiding unintentional differences.
Transcript: “Avoid instances of configuration drift… all of your systems remain in compliance…” (3:39–4:02)
What is the role of source control in managing IaC?
It ensures centralized version tracking, avoids unauthorized changes, and allows for controlled deployment.
Transcript: “To ensure that level of control… you need source control… manage any type of change…” (5:35–5:47)
What is Git and how is it used in IaC?
Git is a version control system used to track changes and collaborate on infrastructure code across teams.
Transcript: “A very popular type of version control system is Git… maintain these source codes…” (6:14–6:27)
What are code branches in version control used for?
To test and develop changes separately before merging them into the main production code.
Transcript: “Allows us to create branches… test changes… merge back into production…” (7:35–8:06)
How are merge conflicts handled in version control systems?
The software detects conflicts when multiple edits are made to the same line, and they must be resolved manually or automatically.
Transcript: “There will obviously be a conflict… version control software… recognize and manage…” (7:00–7:33)
What is branching in version control, and how is it used in Infrastructure as Code (IaC)?
Branching allows developers to create a separate version of an IaC configuration file to test or develop changes independently. Once validated, the branch can be merged back into the main (production) version.
Transcript: “We can create a version of an infrastructure as code definition file… configure it in a testing environment for upgrades… and then merge it back into the production environment.” (7:35–8:06)
