  1. What is the term for Azure's global network of datacenters organized into geographic locations?

    Answer: Azure Regions

    Azure Regions are geographic locations around the world where Azure datacenters are located. Each region contains one or more datacenters connected by a low-latency network.

  2. Which Azure storage tier is most cost-effective for storing data that is rarely accessed and can tolerate higher retrieval latency?

    Answer: Archive tier

    The Archive tier is the lowest-cost Azure Blob Storage tier, designed for data that is rarely accessed and where retrieval latency of hours is acceptable. Storage costs are lowest but retrieval costs are highest.

  3. What Azure feature automatically adjusts the number of virtual machine instances based on demand to maintain performance while minimizing cost?

    Answer: Azure Autoscale

    Azure Autoscale automatically adjusts the number of compute resources (like VMs or App Service instances) based on demand, scaling out during peak times and scaling in during low demand.

  4. Which Azure service acts as a global content delivery network (CDN) to reduce latency by caching content closer to users?

    Answer: Azure CDN

    Azure CDN (Content Delivery Network) caches static content at edge nodes globally, reducing latency for end users by serving content from a location geographically closer to them.

  5. What is the purpose of Multi-Factor Authentication (MFA) in Azure?

    Answer: To require users to verify their identity using two or more verification methods, adding security beyond passwords

    MFA requires users to provide two or more verification factors (e.g., password plus phone code) to authenticate, significantly reducing the risk of account compromise from stolen passwords.

  6. Which Azure service allows you to run small pieces of code in the cloud without managing servers, paying only when the code executes?

    Answer: Azure Functions

    Azure Functions is a serverless compute service that lets you run event-driven code without provisioning or managing servers. You pay only for the time your code runs.
