Explore essential Azure concepts with these common interview questions focused on cloud computing, security, storage, networking, and more. This quiz is designed to help candidates assess their fundamental knowledge of Azure services and practices.
Which Azure cloud model allows you to deploy both on-premises and cloud resources, enabling a unified environment?
Explanation: A hybrid cloud model combines resources from both on-premises and cloud platforms, offering flexibility and integration for businesses. Single cloud and public cloud refer to one-source solutions, lacking the on-premises component. Internal cloud does not specifically describe combining on-premises with cloud resources.
Which Azure service should you use to host and manage virtual machines for running custom applications?
Explanation: Virtual Machines provide scalable and configurable infrastructure for running different operating systems and applications. Blob Storage is intended for storing unstructured data, not for running applications. Logic Apps automate workflows, and Cosmic Tables is not a standard Azure service.
In Azure, what is the main purpose of a resource group?
Explanation: Resource groups are used to group related resources, making them easier to manage and monitor as a unit. They do not set storage quotas, directly launch virtual machines, or focus solely on encryption. The distractors represent actions or features not handled primarily by resource groups.
Which Azure storage type is best suited for storing large unstructured data like images or videos?
Explanation: Blob storage is optimized for storing large amounts of unstructured data, such as images, videos, and backups. File storage is better for shared file access, Table storage is for structured NoSQL data, and Disk storage is typically used as disks for virtual machines rather than for massive unstructured datasets.
What is the primary function of a virtual network in Azure?
Explanation: A virtual network is designed to securely connect and manage network communication among resources. Storing files is a storage service, running automation tasks is not directly related to networking, and allocating licenses is unrelated to networking functionality.
Which Azure feature helps control who can perform actions on resources using roles and permissions?
Explanation: Role-Based Access Control allows administrators to assign specific permissions to users based on roles, enhancing security. Load Balancer distributes network traffic, Cloud Router is not a standard term in Azure, and Data Replica relates to copying data, not access control.
Why is it important to select an appropriate Azure region when deploying resources?
Explanation: Choosing the right region helps minimize response times for users and ensures compliance with regional data residency laws. It does not influence automatic storage increases, reduce internet bandwidth, or disable security features. The distractors do not address the primary reasons for region selection.
What does 'scaling out' mean when referring to Azure services?
Explanation: Scaling out involves adding more service instances to distribute load and improve performance. Replacing hardware is a maintenance task, not scaling. Upgrading operating systems and reducing network traffic are unrelated to the concept of scaling out.
Which Azure feature enables you to track the health and performance of your resources using dashboards and alerts?
Explanation: Monitoring offers tools to view metrics, set up dashboards, and create alerts for resource performance. Backup focuses on restoring data, File Sync manages data synchronization, and Table View is not a standard monitoring tool. The distractors serve different purposes within Azure.
Which Azure redundancy option ensures that your data is copied to multiple locations within the same region to protect against hardware failures?
Explanation: Locally redundant storage replicates data within a single region to guard against local hardware faults. Geo-zone and global storage are not standard terms; they incorrectly suggest global or cross-region redundancy. Central unique storage is not a valid redundancy option in Azure.
