Describe Core Azure Services Flashcards
What are virtual machines?
Virtual machines are software emulations of physical computers. They include a virtual processor, memory, storage, and networking resources. VMs host an operating system, and you can install and run software just like a physical computer. When using a remote desktop client, you can use and control the VM as if you were sitting in front of it.
what are app services?
With Azure App Service, you can quickly build, deploy, and scale enterprise-grade web, mobile, and API apps running on any platform. You can meet rigorous performance, scalability, security, and compliance requirements while using a fully managed platform to perform infrastructure maintenance. App Service is a platform as a service (PaaS) offering.
What are functions?
When you’re concerned only about the code running your service, and not the underlying platform or infrastructure, using Azure Functions is ideal. Functions are commonly used when you need to perform work in response to an event (often via a REST request), timer, or message from another Azure service, and when that work can be completed quickly, within seconds or less.
what are containers?
Containers are a virtualization environment. Much like running multiple virtual machines on a single physical host, you can run multiple containers on a single physical or virtual host. Unlike virtual machines, you don’t manage the operating system for a container
what are container instances ?
Azure Container Instances offers the fastest and simplest way to run a container in Azure without having to manage any virtual machines or adopt any additional services. It’s a platform as a service (PaaS) offering that allows you to upload your containers, which it runs for you.
Azure Kubernetes Service?
The task of automating, managing, and interacting with a large number of containers is known as orchestration. Azure Kubernetes Service is a complete orchestration service for containers with distributed architectures and large volumes of containers.
what is azure virtual desktop?
Azure Virtual Desktop on Azure is a desktop and application virtualization service that runs on the cloud. It enables your users to use a cloud-hosted version of Windows from any location. Azure Virtual Desktop works across devices like Windows, Mac, iOS, Android, and Linux. It works with apps that you can use to access remote desktops and apps. You can also use most modern browsers to access Azure Virtual Desktop-hosted experiences.
Pergunta:
Which Azure compute resource can be deployed to manage a set of identical virtual machines?
Virtual machine scale sets
Virtual machine availability sets
Virtual machine availability zones
Virtual machine scale sets
That’s correct. Virtual machine scale sets let you deploy and manage a set of identical virtual machines.
Pergunta:
Which of the following services should be used when the primary concern is to perform work in response to an event (often via a REST command) that needs a response in a few seconds?
Azure Functions
Azure App Service
Azure Container Instances
Azure Functions
That’s correct. Azure Functions is used when you need to perform work in response to an event (often via a REST request), timer, or message from another Azure service, and when that work can be completed quickly, within seconds or less.
Pergunta:
Your company has a team of remote workers that need to use Windows-based software to develop your company’s applications, but your team members are using various operating systems like MacOS, Linux, and Windows. Which Azure compute service would help resolve this scenario?
Azure App Service
Windows Virtual Desktop
Azure Container Instances
Windows Virtual Desktop
That’s correct. Windows Virtual Desktop enables your team members to run Windows in the cloud, with access to the required applications for your company’s needs.
O que é a rede virtual do Azure(Vnet)?
Azure virtual networks enable Azure resources, such as VMs, web apps, and databases, to communicate with each other, with users on the internet, and with your on-premises client computers. You can think of an Azure network as a set of resources that links other Azure resources.
O que as redes virtuais do Azure oferecem para funcionalidades de rede essenciais:
Azure virtual networks provide the following key networking capabilities:
Isolation and segmentation
Internet communications
Communicate between Azure resources
Communicate with on-premises resources
Route network traffic
Filter network traffic
Connect virtual networks
what are VPNs?
VPNs use an encrypted tunnel within another network. They’re typically deployed to connect two or more trusted private networks to one another over an untrusted network (typically the public internet). Traffic is encrypted while traveling over the untrusted network to prevent eavesdropping or other attacks.
what are VPN?
A VPN gateway is a type of virtual network gateway
what are ExpressRoute ?
ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection with the help of a connectivity provider
what are the benefits of use expressroute ?
There are several benefits to using ExpressRoute as the connection service between Azure and on-premises networks.
Layer 3 connectivity between your on-premises network and the Microsoft Cloud through a connectivity provider. Connectivity can be from an any-to-any (IPVPN) network, a point-to-point Ethernet connection, or through a virtual cross-connection via an Ethernet exchange. Connectivity to Microsoft cloud services across all regions in the geopolitical region. Global connectivity to Microsoft services across all regions with the ExpressRoute premium add-on. Dynamic routing between your network and Microsoft via BGP. Built-in redundancy in every peering location for higher reliability. Connection uptime SLA. QoS support for Skype for Business.
Quais são as vantagem de usar Gateways VPN?
Conecte datacenters locais a redes virtuais por meio de uma conexão site a site.
Conecte dispositivos individuais a redes virtuais por meio de uma conexão ponto a site.
Conecte redes virtuais a outras redes virtuais por meio de uma conexão rede a rede.
Pergunta:
Tailwind Traders wants to create a secure communication tunnel between its branch offices. Which of the following technologies can’t be used?
Point-to-site virtual private network
Implicit FTP over SSL
Azure ExpressRoute
Site-to-site virtual private network
Implicit FTP over SSL
That’s correct. FTP over SSL can’t be used to create a secure communication tunnel.
Pergunta:
Tailwind Traders wants to use Azure ExpressRoute to connect its on-premises network to the Microsoft cloud. Which of the following choices isn’t an ExpressRoute model that Tailwind Traders can use?
Any-to-any connection
Site-to-site virtual private network
Point-to-point Ethernet connection
CloudExchange colocation
Site-to-site virtual private network
That’s correct. A site-to-site virtual private network isn’t an ExpressRoute model.
Pergunta:
Which of the following options can you use to link virtual networks?
Virtual network peering
Network address translation
Multi-chassis link aggregation
Dynamic Host Configuration Protocol
Virtual network peering
That’s correct. Virtual network peering can be used to link virtual networks.
Pergunta:
Which of the following options isn’t a benefit of ExpressRoute?
Redundant connectivity
Consistent network throughput
Encrypted network communication
Access to Microsoft cloud services
Encrypted network communication
That’s correct. ExpressRoute does provide private connectivity, but it isn’t encrypted.
what are Azure Storage?
Azure Storage, which is a service that you can use to store files, messages, tables, and other types of information. Clients such as websites, mobile apps, desktop applications, and many other types of custom solutions can read data from and write data to Azure Storage. Azure Storage is also used by infrastructure as a service virtual machines, and platform as a service cloud services.
what are azure blob storage
Azure Blob Storage is an object storage solution for the cloud. It can store massive amounts of data, such as text or binary data. Azure Blob Storage is unstructured, meaning that there are no restrictions on the kinds of data it can hold. Blob Storage can manage thousands of simultaneous uploads, massive amounts of video data, constantly growing log files, and can be reached from anywhere with an internet connection.
what blob storage is ideal for?
Blob Storage is ideal for:
Serving images or documents directly to a browser. Storing files for distributed access. Streaming video and audio. Storing data for backup and restore, disaster recovery, and archiving. Storing data for analysis by an on-premises or Azure-hosted service. Storing up to 8 TB of data for virtual machines.
