FREE AZ-900: Microsoft Azure Fundamentals Questions and Answers
A business does not need its own data center if it hosts its infrastructure in ________.
A business that uses a public cloud to host its infrastructure is free to shut down its data center. One of the most popular deployment models is the public cloud. Since everything operates on the hardware of the cloud provider in this instance, there is no need to manage or update local hardware. A private cloud, on the other hand, is housed in your own data center. As a result, if you use a private cloud, you cannot close your data center.
What Azure service allows for the management of virtual networks, subnets, and network security groups?
Users may manage virtual networks, subnets, and network security groups using Azure Virtual Network, which enables them to govern traffic flow and protect their applications.
Which Azure service offers an orchestration service for Kubernetes containers that is fully managed?
A fully-managed Kubernetes container orchestration service, Azure Kubernetes Service (AKS) makes it simple to install and maintain containerized applications.
Software as a Service (SaaS) implementation makes us accountable to _________.
You are in charge of configuring the Software as a Service (SaaS) solution as you implement it. SaaS requires the least amount of management because the cloud provider is in charge of it all, allowing the user to utilize the program without any issues. Additionally, cloud-based applications like email, calendars, and office tools can be accessed and used via the Internet by users of software as a service (SaaS).
What Azure services are used to create, distribute, and maintain applications?
Developers can create, distribute, and manage apps with Azure Functions without having to worry about infrastructure thanks to this serverless computing service.
A business has a network of servers that is located on its premises. All of the company's servers will be moved to Azure. John has been tasked with coming up with a strategy to guarantee that some of the servers are accessible in the event that one Azure data center experiences a prolonged outage. What is Peter supposed to do here?
A system's ability to maintain normal operation in the event that some of its components fail or develop a fault is known as fault tolerance. The level of control for ensuring the availability of the applications and data on the virtual machines is increased by the Availability Zones. A region's Availability Zones are physically separated from one another to protect applications and data from data center failures. Additionally, Azure provides a Virtual Machines SLA uptime of 99.99% with Availability Zones. Therefore, we may safeguard the applications and data from the loss of a data center by architecting solutions that use replicated Virtual Machines in zones.
Which Azure service offers a fully managed, globally scalable NoSQL database?
A fully-managed NoSQL database with global scalability, Azure Cosmos DB is a fantastic option for applications needing high availability and low latency.
What are the primary advantages of hosting web apps with Azure App Service?
Automatic scaling, which enables the application to deal with increased traffic without user intervention, is one of the key advantages of using Azure App Service to host web applications.
Which of the following benefits of cloud computing is its main advantage?
Cost savings are one of the main advantages of cloud computing. Organizations can lower their hardware and software expenditures by switching to the cloud and only paying for the services they really use.
What qualifies as a characteristic of the public cloud?
(A) Dedicated hardware
(B) Unsecured connections
(C) Limited storage
(D) Metered pricing
(E) Self-service management
We only pay for the resources that are really used with the Azure Cloud service's metered pricing. Public cloud services also provide a self-managed service because you can add, modify, and remove resources through the interface as needed. Hardware is not dedicated because it is shared by users of public clouds. As a result, cloud connections are protected. Additionally, cloud storage is practically limitless, and public cloud services are pay-as-you-go with no capital expenditures. The public cloud also provides self-service management options.
A company plans to move all of its resources and data to Azure. Only Platform as a Service (PaaS) solutions must be used in Azure, according to the migration plan specified. John has been asked to set up an Azure environment that complies with the migration plan's requirements. John proposes setting up Azure SQL databases and an Azure App Service. Does the proposed remedy satisfy the demand?
Elasticity offers the capability to increase computing resources as needed and decrease them as not needed to cut costs. Autoscaling is one instance of elasticity. With elastic computing, you can easily increase or reduce the processor, memory, and storage power of your computer to accommodate shifting demands without having to worry about capacity planning or engineering for peak usage. Additionally, cloud elasticity enables a company to avoid paying for any extra resources or capacity that go unused.
Which advantage does using Azure virtual machines (VMs) primarily provide?
The ability to scale up or down as necessary to satisfy shifting demands is one of the key advantages of using Azure virtual machines. Users are able to avoid overspending on resources and buying more than they require thanks to this.
Which of the following types of Azure storage is most suited for workloads involving big data analytics?
Users can store and analyze massive amounts of data with Azure Data Lake Storage, a form of Azure storage that is tailored for big data analytics workloads.
What does the Azure service that offers identity and access management go by?
Users can log in and access cloud resources by using Azure Active Directory, a service that manages identity and access.
What actions should you take if you intend to move a public website to Azure?
When choosing Azure Websites as your hosting solution, there are a few crucial characteristics to take into account in order to shift to a cloud platform. For example, it ought to be internationally accessible, have an integrated load balancer, and more.
Which of the following is an Azure service that gives consumers the ability to encrypt and monitor their network traffic?
Users may manage and safeguard their network traffic using the Azure Firewall service, which gives them control over who can access their resources and applications.
