Azure Fundamentals (AZ-900) Practice Questions with Verified Answers

Azure Fundamentals (AZ-900) Practice Questions with Verified Answers What are the 4 basic services that Cloud Providers provide? CANS; Compute power - such as Linux servers or web applications, Analytics - such as visualizing telemetry and performance data, Networking - such as secure connections between the cloud provider and your company, and Storage - such as files and databases. What are some advantages of the cloud? High availability, Scalability - vertical and horizontal, Elasticity, Agility, Geo-distribution, and Disaster Recovery What are some benefits of using Azure? Prepare for the future: Continuous innovation from Microsoft supports your development today and your product visions for tomorrow. Build on your terms: Build how you want and deploy where you want to. Operate hybrid seamlessly: With on-demand deployment of extra resources, you can expand your configuration for sudden spikes in operation What are typical Compute power choices? VACS Virtual Machines, Azure App Service, Containers, and Serverless Computing What is the difference between VMs and Containers? Containers don't need a host OS and are smaller, thus being more resource efficient than VMs. What is the main benefit of Serverless Computing compared to VMs or Containers? The serverless model differs from VMs and containers in that you only pay for the processing time used by each function as it executes. VMs and containers are charged while they're running, even if the applications on them are idle. True or False: You can have multiple Azure subscriptions at the same time. True Why would you have multiple Azure subscriptions simultaneously? Some companies do this for billing purposes; they get separate billing and invoicing reports. Or for separating Production from development subscriptions. Who owns the Azure subscription? The person that creates the subcription What is a geography and why do they matter? An Azure geography is a discrete market typically containing two or more regions that preserve data residency and compliance boundaries. They matter because: 1. Geographies allow customers with specific data residency and compliance needs to keep their data and applications close. 2. Geographies ensure that data residency, sovereignty, compliance, and resiliency requirements are honored within geographical boundaries. 3. Geographies are fault-tolerant to withstand complete region failure through their connection to dedicated high-capacity networking infrastructure. Which are the current Geographies? Americas Europe Asia Pacific Middle East and Africa Azure services that support availability zones fall into which two categories? Zonal services - you pin the resource to a specific zone (for example, virtual machines, managed disks, IP addresses) Zone-redundant services - platform replicates automatically across zones (for example, zone- redundant storage, SQL Database). What are region pairs and why are they important? Each Azure region is always paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away. This approach allows for the replication of resources (such as virtual machine storage) across a geography that helps reduce the likelihood of interruptions due to events such as natural disasters, civil unrest, power outages, or physical network outages affecting both regions at once. Does every region have two or more Availability Zones? Not every region has support for Availability Zones. The following regions have a minimum of three separate zones to ensure resiliency: Central US East US 2 West US 2 West Europe France Central North Europe
