Ques:- What is classification analysis and how does it work
Asked In :-
Unyscape Infocom Pvt. Ltd., Xoriant Solutions Pvt Ltd, Fluid AI, Queppelin Technology Solutions, MattsenKumar Services, Protege Solutions, STIC SOFT E-SOLUTIONS, Toxsl Technologies, TNQ Technologies, Oodles Technologies,
Right Answer:
Classification analysis is a data analysis technique used to categorize data into predefined classes or groups. It works by using algorithms to learn from a training dataset, where the outcomes are known, and then applying this learned model to classify new, unseen data based on its features. Common algorithms include decision trees, logistic regression, and support vector machines.

Ques:- What is Azure Resource Manager and how does it manage resources
Asked In :-
KRIOS Info Solutions, SenecaGlobal IT Services, Solugenix India, Aris Global Software, eGain Communications, Stridely Solutions, ARMIA SYSTEMS, UCA, Nohitatu, SRV Media,
Right Answer:
Azure Resource Manager (ARM) is a management framework in Microsoft Azure that allows users to deploy, manage, and organize Azure resources. It provides a consistent management layer through which resources can be created, updated, and deleted in a unified manner. ARM uses resource groups to organize resources, enabling easier management, access control, and deployment of applications.
