Microsoft Azure Freshers Advanced Experienced level Latest Interview Questions Answers
What are the differences between Azure Service Manager and Azure Resource Manager?
Ans: ASM uses XML REST API and ARM uses JSON REST API. In ASM, it is difficult to delete the resources which have been created and in ARM we can easily group to delete the resources. ASM supports only specific PaaS workloads and in ARM it supports all workloads of PaaS.
Provide few Advantages of Resource Group?
Ans: In Resource Manager, we could easily maintain all the services which have been created under a single resource group which could be segregated by application wise if required. If we required deleting the services, instead of deleting one by one, we can able to delete all the services in a single click by deleting the resource group. To provide a permission of individual service, we could provide a permission to the resource group, whereas provided permission will be implemented to all the services.

What is the best feature is used for handling failover between regions in Azure?
Ans: Using Traffic Manager, we could handle failover within the regions.
Could I able to use same Virtual Network Gateway for both VPN & Express Route?
Ans: No, Virtual Network Gateway needs to be created separately for different types.
I have an application running in my On-Premises and I had backed up the environment to Azure East US region. If On-Premises application failed to access, could I able to switch to Azure environment?
Ans: Yes, using Site Recovery, we could handle fail over and fail back to On-Premises and Azure environment.
Could I able to maintain/manage my On-Premises Active Directory using Azure Active Directory?
Ans: Yes, using Azure AD Connect Health we could monitor the actions which are performed in your On-Premises Active Directory.
I have IIS Web Server running on two Windows Machine with different port numbers like 80 & 81. Could I able to map these servers in Azure Load Balancer?
Ans: Yes, we could able to do that by creating separate Load Balancer Rules in Azure.
In AWS, maintenance is handled by Availability Zone wise. Any Idea about maintenance in Azure?
Ans: In Azure, maintenance is handled by region wise.
Could I able to use custom Images / Private Images for VM Scale Sets using Portal?
Ans: No. At present, there is no option to use private Images in VM Scale Sets using Portal and same could be achieved in CLI / PowerShell / Template.
Is there any possibility to add more than one Private IP Address for single Virtual Machine?
Ans: Yes. By adding NIC, we could able to attach more than one Private IP Address for one Virtual Machine.
I have 10 Virtual Machines and I would require a common file sharing between all these Virtual Machines. What will be the best feature recommended to achieve this?
Ans: Azure File System could be used as a common repository which shares the data with all these Virtual Machines using SMB, NFS & FTPS.
Does Oracle as a Database Service Available in Azure?
Ans: No, Azure doesn’t have a Database as a Service for Oracle.
If I want to distribute a Website which is available in Storage Container without replicating, what is the recommended solution?
Ans: Using CDN Profiles, we can distribute the content across the globe and latency will be reduced by delivering the content from Edge Location instead of reaching the original server.
Does Geo Replication support in PostgreSQL Database service which is offered by Azure?
Ans: At present, there is no support on Geo-Replication for PostgreSQL and it may be in Azure Road Map.
If the transaction between my Application Server and Database Server are delayed due to Disk IOPS. What is the solution to avoid this issue?
Ans: We could use any Database as a Service offered by Azure. Or else, using Redis Cache, we could feed the frequent accessible data in it and map the Redis URL into Application as the first point of contact to store/retrieve the information.
Could I able to login to Linux Virtual Machine without a password?
Ans: Yes, using Key Vault mapping to anyone Admin VM, we could be able to login to another Virtual Machine without a Password.
