Which of the following are characteristic of private clouds? High scalability Lower costs Improved security Limited flexibility
High scalability Improved security Private clouds still afford the scalability and efficiency of a public cloud. Resources are purchased and available to meet your business needs. Because resources are not shared with others, private clouds provide higher levels of control and security. Often, private cloud deployments require paying for hardware and services that remain idle for long periods. This results in higher costs. With a private cloud, your organization can customize its cloud environment to meet specific business needs..

You have an Azure subscription that contains the following unused resources: Network Interface (nic0), Static Public IP (pip1), Standard Load Balancer (lb1) with 5 rules configured, Virtual Network (VNet2) = 10.1.0.0/16, and a Stopped (Deallocated) Virtual Machine (VM3). Which (2) of these unused resources should you remove to lower cost ? lb1 VNet2 pip1 nic0 VM3
lb1 pip1 lb1 and pip1 are the correct answers. The pricing for a Standard Load Balancer is based on the number of rules configured (load balancer rules and NAT rules) and data processed. However, there is no hourly charge for the Standard Load Balancer itself when no rules are configured. Since this load balancer contains rules, it should be removed to save money. There is a charge for static public IP addresses irrespective of the associated resource (unless it is part of the first five static ones in the region), so this resource should be removed. Virtual networks are provided free of charge. The only cost associated are data transfers in and out of the virtual network. If the virtual network is empty, then there should be no data and can remain in the subscription. Stopped virtual machines (which have been shut down from the operating system of the VM) will still incur charges. However, stopped and deallocated virtual machines (shut down from the Azure Portal or via Azure command line tools) do not continue to incur charges until such time as they are restarted. Unused network interfaces do not incur charges and can either remain in your subscription or removed for housekeeping purposes. Pricing Virtual Machine IP Address Options | Microsoft Azure

You are the Systems Administrator for a local university. You are deploying several sets of systems that will be used for research and development teams. Each set of systems will be uniform in nature, containing the same number and type of Azure resources. What should you recommend to automate the creation of these Azure resources? Azure Resource Manager templates Multiple Azure subscriptions Virtual machine scale sets Management groups
Azure Resource Manager templates An Azure Resource Manager template is the framework by which resources are created. They can be used to define and automate the creation of similar resources. A subscription is an agreement with Microsoft to use one or more Microsoft cloud platforms or services, for which charges accrue based on either a per-user license fee or on cloud-based resource consumption. Azure management groups provide a level of scope above subscriptions. They are not used to automate the creation of resources. Azure virtual machine scale sets let you create and manage a group of identical, load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide high availability to your applications and allow you to centrally manage, configure, and update a large number of VMs. However, they are simply the end product of Azure automation.

You are the Azure Administrator for Radio Gaga, LTD. You have a resource group named RG-RG and need to ensure no other administrators can create virtual networks in this resource group. What can you implement to accomplish this? Azure policy Locks Properties Access Control (IAM)
Azure policy Azure Policy is correct as it is used to enforce different rules and effects over your resources, such as limiting what actions different administrators can perform within your RG-RG resource group. The other answers are incorrect: Access Control can be used to prevent the creation of Azure resources, but improper use could prevent required system access from other administrators - this is not the best selection; Locks can be used on a resource to prevent accidental deletion or modification of a resource group - for example; Properties are typically read-only values for an Azure resource, such as its resource ID, subscription, resource group, and other information. Overview of Azure Policy - Azure Policy | Microsoft Docs
You attempt to create several managed disks in your Azure environment. In the Portal, you receive a message that you must increase your Azure subscription limits. What should you do to increase the limits? Upgrade your support plan. Use Azure PowerShell to create the new managed disks. Modify an Azure policy. Create a new support request.
Create a new support request. If you want to raise the limit or quota above the default limit, open an online customer support request at no charge. Modification of an Azure policy will not increase the limits associated with Azure resources. Azure resource limits are bound to any tool set being used to create them. Limits for Portal-created resources apply to those created with PowerShell and Azure CLI. The Azure support plan associated with an Azure subscription has no bearing on the number of resources that can exist within a subscription..

Which of the following statements regarding Azure Virtual Machines is true? Deleted virtual machines will still incur charges for storage. If a virtual machine stays stopped and deallocated for 30 days, it will be deleted. Virtual machines can be auto-resized to combat system performance. Two virtual machines with the same size will incur the same monthly charges.
Deleted virtual machines will still incur charges for storage. When a virtual machine is deleted, its managed disk remains in the Azure portal and can be used to create a new virtual machine. Until this disk is manually removed, you will incur charges for the disk whether it is in use or not. Virtual machine scale sets can be auto-scaled to combat system performance. If a virtual machine needs to be resized, it must be done manually. Two virtual machines of the same size will incur different monthly charges as the charges are based on a number of metrics, such as: CPU usage, disk I/O, type of storage assigned and storage usage. Stopped and deallocated virtual machines will not be deleted after 30 days, they remain in the Azure portal until they are manually removed.

Which statement best describes the benefits of the economy of scale of using cloud providers like Microsoft Azure? Being able to run more workloads in Azure than your own on-premise means your business can scale bigger Since Microsoft is a more extensive business than it's primary competitors, AWS and Google Cloud Platform, it can deliver services more cheaply Since Azure owns and runs so much hardware, they can do so more efficiently, and pass on the savings to the customer Leveraging the cloud to deliver larger and more powerful services gives a company an advantage over competitors
Since Azure owns and runs so much hardware, they can do so more efficiently, and pass on the savings to the customer The economy of scale comes from the ability of cloud providers to run so much hardware, and to do so with great efficiency, that their cost of operating it is substantially lower than if we were to do it ourselves on-premise. These cost savings can then be passed along to us as consumers. The ability to scale larger and deliver more powerful services do not translate towards an economy of scale, although they are benefits of Cloud Computing. While Microsoft does have a very different business model to AWS and Google Cloud Platform, all three are able to leverage the economy of scale in similar ways; something which is not unique to Microsoft.

You have a web application on Azure with a number of virtual machines to run various processes. One of these virtual machines is in charge of processing images. Which Azure service could you use to route all requests for the "/image/" URLs to this specific VM? Use an Application Gateway to route URLs containing the "/image/" path. Implement a content delivery network to route URLs containing the "/image/" path. Use Azure Load Balancer to route URLs containing the "/image/" path. Use a VPN Gateway to route URLs containing the "/image/" path.
Use an Application Gateway to route URLs containing the "/image/" path. An Application Gateway is used specifically for routing traffic based on parameters in the traffic itself. This could be all requests to the "/images/" path of the URL being sent to a specific VM. A VPN Gateway is used to securely connect an Azure Virtual Network with an on-premises network. A CDN does not route traffic. A Load Balancer routes all traffic without looking at it. What is Azure Application Gateway | Microsoft Docs
