Microsoft Azure AZ-900 info by David Papkin


Q & A


How to download billing invoice and daily usage data from your Azure subscription?


The data can be downloaded using the Azure Portal.


How to manage Azure classic resources from the command line?


Azure CLI 1.0 . It will continue to be the tool for managing Azure Service Management (ASM)–based (“classic”) resources—that is, commands accessed via azure config mode asm.


What things should be considered when migrating your virtual machines (VM) from on-premises to Azure?


Security, Compatibility, Cost, Price.


Can virtual machines be moved to a different region or vnet?


Although possible, not all resources might be able to moved.

Better to take a snapshot of the disks and use to create VM in new region/vnet.


What Azure role is needed for a user to fully manage all objects in Azure , including access?


Global Administrator


How does an Azure Webapp and a IaaS Vm with Web Server role differ?


Azure Webapp is a PaaS , which is fully managed by Azure. All HA and patching are done by Azure.

IaaS VM is managed by the customer, all patching, security, HA needs to be managed by the customer.

What are some cloud computing advantages?


There are several advantages that a cloud environment has over a physical environment that Tailwind Traders can use following its migration to Azure.

  • High availability: Depending on the service-level agreement (SLA) that you choose, your cloud-based apps can provide a continuous user experience with no apparent downtime, even when things go wrong.
  • Scalability: Apps in the cloud can scale vertically and horizontally:
    • Scale vertically to increase compute capacity by adding RAM or CPUs to a virtual machine.
    • Scaling horizontally increases compute capacity by adding instances of resources, such as adding VMs to the configuration.
  • Elasticity: You can configure cloud-based apps to take advantage of autoscaling, so your apps always have the resources they need.
  • Agility: Deploy and configure cloud-based resources quickly as your app requirements change.
  • Geo-distribution: You can deploy apps and data to regional datacenters around the globe, thereby ensuring that your customers always have the best performance in their region.
  • Disaster recovery: By taking advantage of cloud-based backup services, data replication, and geo-distribution, you can deploy your apps with the confidence that comes from knowing that your data is safe in the event of disaster.

What are the differences between Capital Expenses (CapEx) and Operational Expenses (OpEx)


Capital expenses vs. operating expenses

There are two different types of expenses that you should consider:

  • Capital Expenditure (CapEx) is the up-front spending of money on physical infrastructure, and then deducting that up-front expense over time. The up-front cost from CapEx has a value that reduces over time.
  • Operational Expenditure (OpEx) is spending money on services or products now, and being billed for them now. You can deduct this expense in the same year you spend it. There is no up-front cost, as you pay for a service or product as you use it.

What can you use to view your costs and billing info?


Cost Management and Billing.


What are some monitoring tools that can be used with Azure?


  1. Azure Monitor –  It delivers a comprehensive solution for collecting, analyzing, and acting on telemetry from your cloud and on-premises environments.
  2. Azure Alerts – Azure Monitor Alerts help you detect and address issues before users notice them by proactively notifying you when Azure Monitor data indicates there might be a problem with your infrastructure or application.
  3. Log Analytics – Log Analytics is a tool in the Azure portal that’s used to edit and run log queries against data in the Azure Monitor Logs store
  4. Network Watcher –  Detect and monitor issues related to the network performance of infrastructure as a service (IaaS) resources in Microsoft Azure.


What are some challenges and benefits of using Azure for Cloud Computing ?



How can you categorise billing for different departments and make sure this is enforced?


You can use tags for the different departments.

You can use Azure Policy to make sure each department uses the tags.
