Exam AZ-600: Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub Interview Questions
Azure is the second most popular cloud provider for Infrastructure as a Service, according to many enterprises. What exactly does this imply? Clearly, many firms are looking for Azure certified professionals. And we’re here to help you prepare for your next Azure interview! This blog is dedicated to Exam AZ-600: Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub Interview Questions and Answers. For your convenience, we’ve gathered a collection of top azure interview questions centered on the positions of Azure Solution Architect, Azure Developer, and Azure System Admin.
1.What is cloud computing, and how does it work?
It refers to the usage of internet servers to “store,” “handle,” and “process” information. Instead of using your own servers, you are using someone else’s to complete your task, and you are paying them for the time you use it.
2. What are the various cloud deployment models available?
The three cloud deployment models are as follows:
- Public Cloud: Your cloud provider owns the infrastructure, and the server you’re utilising could be a multi-tenant system.
- Private Cloud: You own the infrastructure or your cloud provider provides you with that service solely. For example, you might host your website on your own servers or with a cloud provider on a dedicated server.
- Hybrid Cloud refers to the usage of both public and private clouds at the same time. For instance, you may store secret data on your in-house computers yet host your company’s public-facing website in the public cloud. A hybrid cloud would be this type of setup.
3. What exactly is Microsoft Azure, and why is it so popular?
The companies that supply cloud services are referred to as Cloud Providers, as previously state. There are numerous cloud providers available, one of which is Microsoft Azure. It’s used to connect to Microsoft’s cloud infrastructure.
4. Why do we employ roles, and what are they?
In layman’s terms, roles are nothing more than servers. These servers are Platform as a Service virtual machines that are control and load-balanced to achieve a common aim.
In Microsoft Azure, there are three sorts of roles:
- Web Role
- Worker Role
- VM Role
5. Is it feasible to use Azure Resource Manager to create a Virtual Machine in a Virtual Network that was created using traditional deployment?
This is incorrect. You can’t use Azure Resource Manager to deploy a virtual machine onto a virtual network configured with traditional deployment.
6.What are Azure virtual machine size sets?
Scale sets are Azure compute resources that may be use to deploy and manage a group of identical virtual machines. Scale sets are meant to provide genuine autoscale with all VMs configured the same way, and no pre-provisioning of VMs is necessary. As a result, developing large-scale services for big computing, big data, and containerized workloads is easy.
7. Is it possible to use data discs with scale sets?
Yes. A scale set can specify an associated data disc configuration for all VMs in the set. Other data storage options include:
- Files in Azure (SMB shared drives)
- Secondly, Temp drive OS drive (local, not backed by Azure Storage)
- Next, Data service in Azure (for example, Azure tables, Azure blobs)
- Also, Service for external data (for example, remote database)
8. What is an Availability Set, and how does it work?
An availability set is a logical grouping of virtual machines that helps Azure understand how your application is construct for redundancy and availability. To deliver a highly available application and achieve the 99.95 percent Azure SLA, it suggest that two or more VMs be establish inside an availability set. When using Azure Premium Storage with a single VM, the Azure SLA applies to unscheduled maintenance events.
9. What are fault domains and how do they work?
A fault domain, like a rack in an on-premise data center, is a logical group of the underlying hardware that shares a common power source and network switch. The Azure platform distributes your VMs among various fault domains as you construct them inside an availability set. This method reduces the impact of physical hardware failures, network outages, and power outages.
10. What are update domains and how do I use them?
An update domain is a logical collection of underlying hardware that may be service or rebooted at the same time. The Azure platform distributes your VMs among various update domains as you build VMs inside an availability set. As the Azure platform undergoes periodic maintenance, this strategy assures that at least one instance of your application is always operating. During planned maintenance, the order in which update domains are rebooted may not be sequential, but only one update domain is rebooted at a time.
11. What are Network Security Groups, and what do they do?
A list of Access Control List (ACL) rules that allow or prohibit network traffic to subnets, NICs, or both is containe in a network security group (NSG). Subnets or individual NICs connected to a subnet can be associate with NSGs. The ACL rules for an NSG that is associated with a subnet apply to all the VMs in that subnet. Furthermore, by directly associating an NSG with a NIC, traffic to that NIC can be restricted.
12. Do Azure availability sets work with scale sets?
Yes, as explained. An implicit availability set with 5 fault domains and 5 update domains is known as a scale set. Multiple placement groups, which are equal to multiple availability sets, span scale sets of more than 100 VMs. A scaling set of VMs and an availability set of VMs can both exist in the same virtual network. Control node VMs (which often require special configuration) are often place in an availability set, whereas data nodes are placed in the scale set.
13. What exactly is a “break-fix” problem in Exam AZ-600?
Break-fix issues are technical issues that require intervention by a support organisation to be restored to working order. It is an industry term that refers to “work involved in supporting a technology when it fails in the normal course of its function, requiring intervention by a support organisation to be restored to working order.”
14. What is the purpose of Azure Active Directory?
Azure Active Directory is a system for managing identity and access. It’s utilize to give your employees access to certain products and services on your network. Salesforce.com, Twitter, and other sites are examples. Azure Active Directory includes some built-in support for applications in its gallery that may be added directly.
15. What happens when the maximum number of failed tries to authenticate yourself with Azure AD is reached?
To lock accounts, we employ a more advanced technique. This is determined by the request’s IP address and the passwords submitted. The length of the lockout is also determined by the likelihood of an attack.
16. Where can I obtain a list of pre-integrated Azure AD applications and their capabilities?
There are around 2600 pre-integrated applications in Azure AD. Single sign-on is support by all pre-integrated applications (SSO). SSO allows you to access your apps using your organization’s credentials. Automated provisioning and de-provisioning are also support by some of the apps
17. How can I use on-premises applications with Azure Active Directory in Exam AZ-600?
Azure Active Directory provides a simple and safe way to connect to the web applications of your choice. There’s no need to update your network architecture or use a VPN to access these apps the same way you use your SaaS apps in Azure AD.
18. What is Azure Service Fabric, and how does it work in Exam AZ-600?
Azure Service Fabric is a distributed systems platform that makes scalable and dependable microservices easy to package, deploy, and manage. The significant obstacles in designing and administering cloud applications are also addressed by Service Fabric. Developers and administrators may focus on designing mission-critical, demanding workloads that are scalable, dependable, and manageable instead of dealing with complex infrastructure issues. Service Fabric is the next-generation middleware framework for developing and managing enterprise-class, tier-1, cloud-scale apps.
19. Are there any constraints in terms of scale for clients who use managed discs?
Managed Disks eliminates the storage account limitations. However, by default, the number of manage drives per subscription is set to 2000.
20. What is Azure Redis Cache, and how does it work in Exam AZ-600?
Redis is an in-memory data structure store that can be use as a database, cache, or message broker. It is open source (BSD licenced). The popular open-source Redis cache is the foundation for Azure Redis Cache. It gives you access to a Microsoft-managed, secure Redis cache that you can access from any Azure application. Strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, and geographic indexes with radius queries are all supported.
21. Is it possible to add an existing virtual machine to a set of availability?
No, You must create your VM within an availability set if you want it to be part of it. After a VM has been construct, there is currently no way to add it to an availability set.
22. Why isn’t there an MSDN class library reference for Azure Redis Cache like some of the other Azure services?
Microsoft Azure Redis Cache is base on the popular open-source Redis Cache and can be access via a range of Redis clients written in a variety of computer languages. Each client has its own API that uses Redis commands to call the Redis cache instance. There is no centralized class reference on MSDN since each client is unique, and each client maintains its own reference documentation. There are multiple tutorials that show how to get start with Azure Redis Cache utilizing various languages and cache clients, in addition to the reference material.
23. What are Redis databases, and how do you use them in Exam AZ-600?
Redis Databases are just logical data separations within a single Redis instance. The cache memory is share among all databases, and the amount of memory consumed by each database is determine by the keys and values stored within. A C6 cache, for example, contains 53 GB of memory. You have the option of putting all 53 GB into one database or dividing it up among numerous databases.
24. How much virtual machine storage can I use?
Each data drive has a maximum capacity of 1 TB. The amount of data discs you can use is determine by the virtual machine’s size. Azure Managed Disks are a new and highly recommended disc storage option for Azure Virtual Machines for long-term data storage. Each Virtual Machine can have many Managed Disks. Premium and Standard Managed Disks are two types of long-term storage options offered by Managed Disks.
25. What is Azure Search and how does it work in Exam AZ-600?
Azure Search is a cloud search-as-a-service solution that gives Microsoft control over server and infrastructure management, leaving you with a ready-to-use service that you can populate with your data and use to bring search to your online or mobile application. Using a simple REST API or.NET SDK, you can simply add a powerful search experience to your applications without having to manage search infrastructure or become a search specialist.
26. When configuring the runtime stack, what are the expected settings for the Startup File section?
You specify the PM2 configuration file or your script file for Node.Js. Specify the name of the built DLL in.NET Core. You can provide the Ruby script you want to use to start your program in Ruby.
27. What’s the difference between “price,” “software price,” and “total price” in the Azure Marketplace’s cost structure for Virtual Machine offers in Exam AZ-600?
The cost of the Azure Virtual Machine used to run the software is referred to as “price.” The cost of publisher software operating on an Azure Virtual Machine is referred to as “software price.” The combine total cost of the Azure Virtual Machine and the publisher software operating on an Azure Virtual Machine is referred to as the “total price.”
28. What are the differences between stateful and stateless microservices in terms of Service Fabric?
Service Fabric allows you to create microservice-based applications. Outside of a request and the service’s response, stateless microservices (such as protocol gateways and web proxies) do not keep a mutable state. Next, worker roles in Azure Cloud Services are an example of a stateless service. User accounts, databases, devices, shopping carts, and queues are examples of stateful microservices that maintain a mutable, authoritative state beyond the request and response. Microservices, both stateless and stateful, are use in today’s Internet-scale applications.
29. What are application partitions and what do they mean in Exam AZ-600?
The application partitions are directory partitions that are replicate to domain controllers and are part of the Active Directory system. Domain controllers that are involved in the directory partitioning procedure usually keep a copy of the directory partition. Application partitions have the advantage of being able to be replicate to any individual domain controller in a forest, potentially reducing replication traffic. While domain directory partitions transport all of their data to all of the domains, application partitions in the domain area can only focus on one. Also, this eliminates the need for application partitions and increases their availability.
30. What exactly are Azure Regions in Exam AZ-600?
For compliance or legal reasons, Azure provides various specific regions that you may want to employ while developing your apps.
