FREE AZ-900: Microsoft Azure Questions and Answers
What can you use to link an Azure virtual network to an Azure resource, such as an Azure SQL database?
Azure services are exposed to a virtual network using service endpoints, enabling communication between the two. An on-premises network is connected to Azure via ExpressRoute. You may set up inbound and outbound rules for virtual machines and networks using NSGs. You can link virtual networks together using peering.
You're using IaaS to run a virtual machine in a public cloud. Which model is the most accurate representation of how that resource is managed?
Correct answer: Shared responsibility model
Shared responsibility model is the correct answer. Under the shared responsibility model, management of the resource is shared between the cloud provider and the end-user. The cloud provider is responsible for the cloud services infrastructure and the end-user is responsible for the service being configured and managed correctly.
Which of the following provides an opportunity for all Azure customers to try out the beta and other pre-release features?
Correct answer: Public Preview
Public Preview means that an Azure feature is available to all Azure customers for evaluation purposes.
A data center is no longer necessary for an organization that hosts its infrastructure ________.
Correct answer: in the public cloud
A private cloud is hosted in your datacenter. Therefore, you cannot close your datacenter if you are using a private cloud.
A public cloud is hosted externally, for example, in Microsoft Azure. An organization that hosts its infrastructure in a public cloud can close its data center.
Public cloud is the most common deployment model. In this case, you have no local hardware to manage or keep up-to-date ג€"" everything runs on your cloud provider's hardware.
Microsoft Azure is an example of a public cloud provider.
In a private cloud, you create a cloud environment in your own datacenter and provide self-service access to compute resources to users in your organization.
This offers a simulation of a public cloud to your users, but you remain completely responsible for the purchase and maintenance of the hardware and software services you provide.
Operational expenditure (OpEx) costs include things like building a data center infrastructure. Is the statement correct?
Correct answer: No
Building a data center infrastructure is capital expenditure, not operation expenditure.
What Azure resource includes a virtual processor, memory, storage, and networking resources and is a software simulation of a computer?
Virtual machines are computer hardware simulations created by software. A virtual processor, memory, storage, and networking resources are some of them. You can install and run applications on virtual machines just like you would on a conventional computer because they host an operating system.
You have numerous servers on your on-premises network.
You intend to move all of your servers to Azure.
You must propose a strategy to ensure that some servers are available if a single Azure data center is offline for an extended period of time.
What should your recommendation include?
Correct answer: fault tolerance
Fault tolerance is the ability of a system to continue to function in the event of a failure of some of its components.
In this question, you could have servers that are replicated across datacenters.
Availability zones expand the level of control you have to maintain the availability of the applications and data on your YMs. Availability Zones are unique physical locations within an Azure region. Each zone is made Lip of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures.
With Availability Zones, Azure offers industry best 99.99% UM uptime SLA. By architecting your solutions to use replicated ‘v’Ms in zones, you can protect your applications and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.
Availability zones are available in every Azure region. Is the statement correct?
Correct answer: No
Not all Azure regions support availability zones.
Your organization intends to use Azure to host many custom applications. The applications will give the company's clients with invoicing services. Several required programs and services will be installed for each application.
For all of the applications, you must recommend a cloud deployment solution.
What would you suggest?
Correct answer: Infrastructure as a Service (laaS)
Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. The IaaS service provider manages the infrastructure, while you purchase, install, configure, and manage your own software
You must permit communication between resources on two distinct Azure virtual networks.
What settings should you make?
By employing virtual network peering, you can connect virtual networks. Resources in each virtual network can communicate with one another thanks to peering.
There are data centers for your business in New York and Los Angeles. The business subscribes to Microsoft Azure.
For site resilience, you are setting up the two data centers as geo-clustered sites.
✑ You must suggest a redundant Azure storage solution.
✑ You need to store the following types of data:
✑ Data must be kept on several nodes. Data must be kept on nodes located in different regions. Both the primary location
and the secondary site can read data.
Which option for Azure stored redundancy should be suggested?
As read-only access to the data replicated to the secondary site is provided by RA-GRS, you are able to have improved read availability for your storage account. In the case that the data is not accessible in the primary region after you enable this feature, you may use the secondary location to obtain improved availability. This functionality is opt-in and necessitates geo-replication of the storage account.
In availability zones, only virtual machines running Windows Server can be established. Is the statement correct?
Correct answer: No
Availability zones can be used with many Azure services, not just VMs.
What are the two Azure resources that provide availability zones? Each accurate response offers an entire resolution.
Please select 2 correct answers
Virtual machines, managed drives, load balancers, and SQL databases are the main uses of availability zones.
Due to their small size, small businesses frequently have a _____ pricing per unit.
Correct answer: high
Bigger companies can build internal teams. share resources. invest in research, negotiate prices. etc. All this leads to a lower price per unit. Unfortunately. small companies can't do that which leads to a high unit per price.
Which situation qualifies as a VPN gateway use case?
Virtual network gateways include VPN gateways. Instances of the Azure VPN Gateway are set up on a certain subnet of a virtual network. They can be utilized to establish a Site-to-Site (S2S) VPN connection between virtual networks and on-premises datacenters.
Which Azure compute service can you employ in order to set up and maintain a group of identical virtual machines?
You can install, manage, and scale a group of identical virtual machines using Virtual Machine Scale Sets, an Azure compute resource.
