Storage Solutions, Scaling, and Cloud Infrastructure
(Updated and Verified)
Description: This document provides Microsoft Azure 204 exam practice questions
with 100% correct answers. Topics include App Services, Blob storage, scaling,
traffic management, authentication, and serverless functions. Verified and
structured for certification prep, it helps students and professionals strengthen
their cloud solution skills for the AZ-204 exam.
Storage Durability Options - answer✔✔LRS- Three replicas, one region, protects
against dish, node, rack failures, write is acknowledged when all replicas are
committed, superior to dual parity RAID ZRS- Three replicas, three zones, one region,
protects against disk, node, rack and zone failures, synchronous writes to all three
zones. GRS- Six replicas, two regions (three per region), protects against major
regional disasters, asynchronous copy to secondary. RA-GRS- GRS + read access to
secondary, separate secondary endpoint, recovery point objective (RPO) delay to
secondary can be queried. GZRS- Six replicas, 3+ 1 zones, two regions, protects
against dis, rack, zone and region failures, synchronous writes to all three zones and
, asynchronously copies to secondary. RA-GZRS- GZRS + read access to secondary,
separate secondary endpoint, RPO delay to secondary can be queried. App Service -
answer✔✔- Service for hosting web applications, REST APIs and mobile backends

and can be developed in many of the following languages (.NET, Java, Ruby, Node.JS,
PHP, Ruby). When to choose Linux - answer✔✔- Many application stacks are
optimised for Linux (Ruby, PHP, Node etc.). - New and upcoming frameworks built for
Linux first. - Portability of Docker containers. Web Apps - answer✔✔Scalable
hosting for web applications. Allows you to scale your app without being required to
redesign. Integrates with Visual Studio. Provides an open platform for many different
programming languages. Near instant deployment. App Service Plan -
answer✔✔Logically group apps within a subscription. Used as the unit of billing in
most cases. Multiple app service plans can exist within a single resource group. - Built
in authentication and authorisation (built in token store, logging and tracing and
support for identity providers such as Azure AD, Facebook etc.). App Service Plan
Hybrid Connections - answer✔✔- Enables access to resources in other networks
on any operating system or application. - Correlates to a single TCP host and port
combination. - Web Apps can access on-premise systems securely. - Does not require
firewall. App Service Plan Local Cache - answer✔✔- Provides a write-but-discard
cache. - Created asynchronously when site is started. - Automatically serves content
when cache is ready. - Faster than reading content from Azure Storage directly on
each client request. App Service Environments (ASE) - answer✔✔- App Service
