Free Microsoft Azure Fundamentals (AZ-900) practice questions

Question 01

One Azure service offers a 99.9% monthly uptime SLA and another offers 99.99%. What is the practical difference between these two commitments?

Question 02

In Azure's global infrastructure, what is an Azure region?

Question 03

A bank must back up its Azure virtual machines, on-premises servers, and Azure file shares so it can restore them if data is lost or corrupted. Which Azure service is specifically designed to provide backup and restore of this data?

Question 04

A bank's application needs to react automatically when a customer uploads a check image to Blob Storage by running a small piece of code that extracts data from the image, paying only when that code executes. Which pairing of Azure services best implements this event-driven flow?

Question 05

A bank's finance manager wants to build and price a proposed Azure architecture of specific virtual machines, a database, and storage before deployment, then export and share the estimate. Which Azure tool is designed to produce this pre-deployment cost estimate?

Question 06

A logistics firm keeps its scheduling system in its own datacenter for regulatory reasons but runs its customer-facing website in Azure, with a private connection letting workloads and data move between the two environments. Which cloud deployment model does this describe?

Question 07

A storage architect must design redundancy for critical data that can survive two distinct failures: the outage of an entire availability zone within the primary region, and separately, the loss of the whole primary region. Data must remain synchronously protected across zones during normal operation. Which redundancy option satisfies both requirements?

Question 08

A retailer needs to resize product photos whenever staff upload them. Each job runs for a few seconds, uploads arrive at unpredictable times, and the retailer wants to pay nothing when no images are being processed and to manage no servers. Which computing approach best fits these requirements?

Question 09

An operations team needs to open RDP and SSH sessions to Azure VMs directly from the Azure portal in a browser, without assigning public IP addresses to the VMs and without installing client software. Which service provides this?

Question 10

A bank moves a self-hosted MySQL loan-origination backend to Azure and wants a fully managed service for that specific open-source database engine so it no longer patches the OS or manages backups. Which service should it choose?

Question 11

A bank needs a central way to assess and deploy operating-system updates across its Azure virtual machines and Azure Arc-enabled servers, scheduling patch deployments and viewing update compliance. Which Azure service provides this update-management capability?

Question 12

A bank ingests millions of streaming events per second from its fraud-detection telemetry pipeline and needs a service optimized for high-throughput big-data event and log streaming. Which Azure service is purpose-built for this?
