What allows you to perform maintenance and even updates on an Azure VM instance hosting an application without the need for any downtime? VM Scale Set What is a cost-effective storage option for virtual machines that require improved availability compared to standard HDDs, but do not require high IOPS? Standard SSD disks -- backed by solid-state drives What is guaranteed when a premium SSD disk is provisioned with an Azure VM? storage capacity, IOPS, and throughput performance are all guaranteed If your Azure Virtual Machines need more advanced layer seven distribution and SSL termination, you can implement an Azure Application gateway _______ allow you to easily create and manage multiple Azure VMs that have the same configuration because all the underlying VM instances are created from the same base OS image and configuration virtual machine scale sets -- because in a scale set, all underlying VM instances are created from the same base OS image and configuration. Therefore, it is fairly easy to manage dozens or even hundreds of virtual machines without needing to worry about performing configuration tasks or even about network management. When performing a deployment of a Microsoft Azure Resource Manager (ARM) template, can information be shared between multiple template files? Yes, data can be shared between linked ARM templates Which Azure Resource Manager (ARM) component is used to define the dependencies among the deployed ARM resources? an ARM template What are the recommended ways to interact with Azure Resource Manager when deploying large or repeated deployments? Azure CLI and Azure Powershell When creating an Azure Resource Manager (ARM) template, how can the template be deployed? through Powershell, Azure CLI, or the REST API Descirbe ARM (Azure Resource Manager) it is the backend Azure service you interact with through the Portal, SDK, or CLI to connect to other Azure Services Which section of the ARM template allows you to pass variables into the template to make its functionality more dynamic? Parameters What is ARM's default template deployment mode? Incremental mode An ARM template is submitted as one object and ARM works out the order in which resources should be created. What advantage does this provide? This allows ARM templates to deploy multiple interdependent resources successfully. An ARM Template is idempotent. What does this mean? It means that actions requested in the template are executed in Azure only once, and additional requests have no effect. Which section of an ARM template allows you to provide values for daisy-chaining multiple templates? Outputs In Azure Resource Manager (ARM) templates what advantage do variables provide? Variables simplify template expressions Which of the following is not a section of the Azure Resource Manager template? Inputs Which section of the ARM template consists of key-value pairs that are defined once and can be used throughout the template? Variables Which section of an ARM template allows you to specify what Azure services such as virtual machines, virtual networks, or storage accounts, for example, the template will deploy. Resources who is allowed to create user accounts in an active directory tenant? only global administrators can add users to tenant network contributor role allows you to: manage networks , but not access them where can you set an expiration policy? Only for Office 365 groups in Azure Active Directory (Azure AD) ______ allow developers with the ability to perform A/B testing on Azure app service apps, and provides you a separate deployment environment along with the default production environment deployment slots Azure Web Apps Service a managed service for deploying and running Windows-Based and Linux-based web apps that also support containerized apps Azure App Service Logs 4- Application, Web Server, Detailed Error, and Failed Request Logs The App service plan you select will determine: -number of apps you can host -cost of your app service plan -number of app service features you can use Which service can you integrate with Azure App Service to adopt efficient processes such as continuous deployment? DevOps Which point to site VPN protocol supports only Windows devices? Secure Socket Tunneling Protocol Which point to site VPN protocol can be used to connect from Android, Windows, Linux, and Mac OSX machines? Open VPN vNet Peering allows you to seamlessly connect different Azure virtual networks so that, as far as connectivity goes, both virtual networks appear as one A VPN gateway is used to send encrypted network traffic between an Azure virtual network and an on-prem network over the public internet There are several parameters to define for Auto Scaling to correctly operate in Azure App Service. Which of the following is not an Auto Scaling parameter that needs to be defined? The type of instance Azure App Service should deploy Azure App Service Auto Scaling determines how the service scales horizontally, meaning it determines the number of identical instances that are deployed to support one or several Azure web apps at a given time. With this in mind, you need to define each of the parameters above except for the type of instance. This is determined by the Azure App Service plan one selects, not by the auto scaling configuration. When deciding which Azure App Service plan works best for you, there are multiple factors to consider. Which of the following is not a factor related to the app service plan one selects? The different programming languages and frameworks used in your Azure web apps The separate Azure App service plans host a different number of Azure web apps. For example, the free plan supports 10 while the Standard supports 100, so the number of web apps you need to deploy should be considered. In addition, the apps in a plan all share the same resources, so you could potentially save money by putting lots of apps in one plan, but compute and infrastructure resources are shared between many apps. Another consideration is that not all features are available to all plans. For example, Deployment Slots are only available in standard or above plans. As performance isn't a consideration for this demo, I'm going to select the free plan. What Azure service integrates with Azure App Service to enable continuous deployment and continuous integration workflows? Azure DevOps Azure DevOps provides developer services for support teams to plan work, collaborate on code development, and build and deploy applications. Developers can work in the cloud using Azure DevOps Services or on-premises using Azure DevOps Server. Azure App Configuration provides a service to centrally manage application settings and feature flags. Azure Functions is a cloud service available on-demand that provides all the continually-updated infrastructure and resources needed to run your applications. API Management (APIM) is a way to create consistent and modern API gateways for existing back-end services. What is one tool that a web app in an Azure App Service can use to access on-premises data?. Hybrid Connections Hybrid Connections are a feature of Azure BizTalk Services. Hybrid Connections allow the Web Apps feature in Azure App Service to access on-premises resources behind a firewall. The API Apps tool in Azure App Service allows you to more securely expose your APIs in the cloud with ____ metadata. JSON API Apps in Azure App Service use Swagger, which is a machine readable representation of a RESTful API that is exposed to the client, to enable support for interactive documentation, client SDK generation and discoverability. Azure App Service allows you to secure your web app using ________, through the use of either an existing SSL certificate, or one purchased via the Azure portal. HTTPS Azure Web Apps provides a highly scalable, self-patching web hosting service. To use a certificate in App Service, the certificate must meet all the following requirements: Signed by a trusted certificate authority Exported as a password-protected PFX file Contains private key at least 2048 bits long Contains all intermediate certificates in the certificate chain Which statement regarding the Linux operating system on Azure App Service is correct? Windows and Linux cannot run in the same App Service plan. While you can deploy Linux web apps on Azure App Service, there are a number of limitations. App Service on Linux isn't supported on the shared pricing tier. You are not able to mix Windows and Linux apps in the same App Service plan. You can't mix Windows and Linux apps in the same region within the same resource group. Your Azure App Service plan hosts a webjob that needs to run at the same time every day, to execute a background operation for other applications hosted on the same App Service plan. What Azure App Service feature should one enable under the configuration settings to have the webjob run automatically rather than be manually triggered? Always On Under general settings, the Always on feature keeps your app loaded even when not active. While this might seem like a good feature to improve responsiveness, it's actually required for WebJobs that aren't manually triggered. The other choices are actual setting: You can specify whether to allow FTP deployment or not. You can also turn on web sockets if your app is using SignalR or S push technology. ARR (application request routing) affinity is an interesting setting that works when your app is scaled out to multiple instances. The idea is that when a client establishes a session with a particular instance, ARR assigns them an affinity cookie (as in that client has an affinity with that particular instance) and that instance will service the client until the session has ended. What are Azure App Service deployment slots? Live web applications with their own hostnames, whose content and configuration settings can be swapped between each other Live web applications with their own hostnames, whose content and configuration settings can be swapped between each other. Which of the following is correct regarding the scaling workflows available in the Azure App service? Scale up can be used to increase the CPU resources for an app and Scale out can be used to increase the number of Virtual Machines dedicated to an app. The following scaling mechanisms are present in the Azure App Service: Scale up - Get more CPU, memory, disk space, and extra features like dedicated virtual machines (VMs), custom domains and certificates, staging slots, autoscaling, and more. You scale up by changing your application's App Service pricing tier. Scale out - Increase the number of VM instances that run your app. You can scale out to as many as 20 instances, depending on your pricing tier. Your client has two requirements for their Azure solution utilizing Azure Virtual Machines that affect how it needs to be deployed. They want the highest level of availability, and also large customer populations in distant parts of the globe. What model would generally help address this client's needs? A multi-region active-active model with geo-location based request routing Explanation Due to the fact that this client desires the highest level of availability, it is clear they need multi-regional deployment and not multi-zone. Then there is the issue of the customers on distant parts of the globe, which raises the issue of latency. The two best options in terms of minimal downtime are active/active and active/passive with hot standby, and since the client needs to serve two distinct locations, minimizing service latency is the reason to choose active/active with geo-location based request routing. Which of the following is not an example of a microservice? Virtual machine Explanation Today's Internet-scale services are built using microservices. Examples of microservices include protocol gateways, user profiles, shopping carts, inventory processing, queues, and caches. What is Azure Batch? A platform for running large-scale parallel and HPC applications in the cloud Azure Batch helps you run large-scale parallel and HPC applications efficiently in the cloud. It's a platform service that provides job scheduling and auto-scaling of a managed collection of virtual machines to run the jobs. By using Batch, you can configure workloads to run in Azure on demand or on a schedule and not worry about the complexity of configuring and managing an HPC cluster, VMs or a job scheduler. What statement accurately describes an Azure Function trigger requirement? A function must have exactly one trigger. Explanation Triggers and bindings are a declarative way to define how a function is invoked and what data it works with. A trigger defines how a function is invoked. A function must have exactly one trigger. Triggers have associated data, which is usually the payload that triggered the function. Bindings simplify coding for input and output data. A company is looking at using the Azure Media services to deliver their video content. They have users distributed in many geographic locations. They want to deliver the video content so that the users have the least latency when viewing the video content. Which of the below options can help them achieve this purpose? Use the Azure CDN service along with the Azure Media Services Explanation Azure Media services can be supported by Azure Content Delivery network, so the encoded videos can be pushed to the various CDN locations. The users will then get the content from the location that is closest to them. An application is considered a 'monolith' when _________________________. the entire software package is included in one application Explanation Monoliths are when all of the modules that comprise your software are in one application. For context, this is the opposite of the microservices architecture where different services are broken out into different discreet deployable applications. What is a Batch pool in Azure Batch? A collection of compute nodes on which the user application runs What benefits does deployment within paired regions within Azure offer, in addition to the high availability offered by multi-region deployment? (Choose 2 answers) Added stability during planned updates Prioritized system recovery from an outage Explanation Region recovery order - In the event of a broad outage, recovery of one region is prioritized out of every pair. Applications that are deployed across paired regions are guaranteed to have one of the regions recovered with priority. If an application is deployed across regions that are not paired, recovery might be delayed - in the worst case the chosen regions may be the last two to be recovered. Updates Sequential updates - Planned Azure system updates are rolled out to paired regions sequentially (not at the same time) to minimize downtime, the effect of bugs, and logical failures in the rare event of a bad update. When using Azure Site Recovery, you utilize a process server, a configuration server, a master target server, and a mobility service. However, the configuration of these components varies depending on your recovery plan. How does the configuration vary between an on-premise to Azure plan and an on-premise to secondary site plan? When replicating from on-premise to a secondary site, the master target and configuration servers are in the secondary site. When replicating data from a physical server on-premise to Azure, all the components are based on the primary site. The servers must be configured on-premise, and the mobility service must be installed on VMWare or physical server. If you're replicating to a secondary site, then you need the same components, but the Process server is in the primary site and the Configuration and Master target servers are in the secondary site. What compute service does Azure Functions provide? serverless computing within the Azure Cloud Explanation Azure Functions provide serverless computing via the Azure cloud. Batch computing is provided by Azure Batch, Stream Analytics provides real-time data stream processing, and Virtual Machine Scale Sets allows you to scale and manage sets of Azure virtual machines. An Azure Batch job manages a collection of ____. tasks Explanation A job is created to manage a collection of tasks. Each job is associated with a specific pool where that job's tasks will run. Each task runs the application or script uploaded to process the data files it downloads from the Storage account. As each task completes, it can upload its output to Azure Storage. Which of the following services in Azure is used to hold data such as backup copies, recovery points, and backup policies? Recovery Services Vault Explanation A Recovery Services vault is an online storage entity in Azure used to hold data such as backup copies, recovery points, and backup policies. You can use Recovery Services vaults to hold backup data for various Azure services such as IaaS VMs (Linux or Windows) and Azure SQL databases. Recovery Services vaults support System Center DPM, Windows Server, and Azure Backup Server.
