On Microsoft’s Azure platform, the process and guiding principles for creating and designing cloud-based Azure services are known as Microsoft Azure Architecture. It ensures that your services and apps are developed on a safe, scalable, and reasonably priced foundation.
Applications, virtualized networks, and Azure virtualized hardware all use the Azure Architecture to meet demand. A vital component of this architecture is Software-Defined Networking (SDN).
Using the fundamental elements and continuing management of your cloud solution on Azure, this architecture adheres to the early design phases. Microsoft provides basic plots with pre-built architecture to assist you in creating your project. This Microsoft Azure architecture is one of the most essential AZ-900 exam questions and answers that should fit in your study checklist.
3. Can you explain what PaaS, along with SaaS and IaaS, means?
These are the basic terms used while discussing cloud services, and when preparing for Azure Fundamentals interview questions, these terms are a must-know category.
Understand that Platform as a Service (PaaS) allows you to get a platform to deliver without clearly giving the OS software permission.
Software as a Service, or SaaS for short, is platform infrastructure software that cannot be purchased directly.
Infrastructure as a Service, or IaaS for short, allows you to purchase hardware from the supplier as the customer-configured service of your choice.
4. Which services are used for Azure resource management?
The infrastructure that is involved in managing deployments or deleting all the resources is the Azure resource manager.
It has to be your response when you are questioned about Azure cloud interview questions. As one of the most popular Azure services, Azure Resource Manager may be the subject of additional questions.
Explain the roles of Azure
This is another easy but crucial topic that is part of the AZ 900 interview questions, and it should be addressed as follows:
- Common Roles: Include Owner (full access), Contributor (full access minus permission management), and Reader (view-only).
- Service Machines: These roles help distribute workload, balance resources, and provide necessary access for platform management, ensuring efficiency and performance reliability.

Vertical scaling: Increasing resources on one machine (CPU/RAM).
Horizontal scaling: Adding more machines to distribute the load.
Intermediate AZ 900 Interview Questions
Here is a list of questions that are in the range of medium level. You should prepare these AZ 900 interview questions for a favorable result.
1. Is it possible to set a public DNS or IP address to the Azure Internal Load Balancer?
No. As the name implies, Azure Internal Load Balancer only allows private IP addresses. As a result, giving a public IP address or DNS name is not allowed.
What happens during the Azure ID authentication process if the maximum number of unsuccessful tries is reached?
The process by which the Azure account is locked in the event of a limited number of unsuccessful tries is determined by the protocol that examines the IP addresses of the login requests and the password that was entered.
2. What does Azure’s cspack mean?
Service package files are created using this command-line use. The application can also be prepared for deployment in a compute emulator or Microsoft Azure with the aid of this tool.
Each cloud service project has a.cscfg file, which is the cspack-created cloud service configuration file. It is mostly used to store:
Number of roles for the deployment of each role in the project
The certificates’ thumbprint.
Configuration and settings that are user-defined.
Explain the Azure storage key.
The Azure storage key is used for authentication and access validation to limit data access according to project needs.
In order to simplify authentication, two kinds of storage keys are provided, and they are the primary and secondary access keys.
Among the fundamental AZ-900 exam questions and answers, the Azure storage key should be given a hot spot.
