1.0 Describe cloud concepts AZ-900 Practice Quiz

• A. Delivery of computing services over the internet, including compute, storage, networking, and applications
• B. Treat the cloud provider as solely responsible for end-user data classification
• C. Treat dev/test environments as production with the same compliance controls
• D. Treat governance as a one-time setup rather than continuous management

Cloud computing provides IT services through internet-accessible platforms instead of requiring every resource to be owned and operated locally.

• A. A way to use scalable IT services without building and operating every physical datacenter component
• B. Assume RBAC is unnecessary because IAM users have password complexity rules
• C. Use a spreadsheet as the main deployment platform
• D. Choose a model based on vendor preference rather than business requirements

Cloud computing lets organizations use scalable services while reducing direct responsibility for physical facilities.

• A. Expect a public website to use a private-only cloud endpoint by default
• B. Using remote datacenters to provide technology resources that can be provisioned when needed
• C. Treat scaling out (more instances) as identical to scaling up (bigger instances)
• D. Treat consumption-based pricing as a fixed-fee subscription independent of usage

Cloud computing lets organizations access infrastructure and services from a provider's datacenters on demand.

• A. Treat predictability only as performance predictability and ignore cost predictability
• B. A division of security and operational duties between the cloud provider and the customer
• C. Treat all cloud workloads as the customer's responsibility regardless of service tier
• D. Skip Azure Cost Management because it does not work without Enterprise Agreement

The shared responsibility model explains which tasks are handled by the provider and which remain with the customer.

• A. Skip the Azure Pricing Calculator and estimate cloud cost from on-prem hardware quotes
• B. The provider and customer both have security responsibilities, but they are not responsible for the same layers
• C. Rely on a single Availability Zone for production multi-tier workloads
• D. Treat Azure ExpressRoute as a backup VPN tunnel for site-to-site connectivity

Cloud security is shared across layers such as facilities, infrastructure, identity, data, and applications.

• A. Disable Azure Monitor logging to reduce ingestion cost on production workloads
• B. Choose hybrid cloud only when no on-premises infrastructure exists
• C. Accessing configurable IT resources through a provider-managed platform instead of buying and maintaining all hardware yourself
• D. Believe pay-as-you-go means workloads are free when idle but throttled at peak

Cloud computing shifts many infrastructure tasks to the provider while users consume services as needed.

• A. Assume consumption-based pricing always costs less than reserved capacity
• B. Treat Microsoft Entra ID as just a password directory
• C. Microsoft is responsible for the physical datacenters, while customers remain responsible for their data and access decisions
• D. Treat Azure App Service as IaaS that the customer must patch and harden

Azure operates the underlying cloud infrastructure, but customers still manage data, identities, and configurations they control.

• A. Assume the cloud provider patches every guest OS and application by default
• B. Assume cloud reliability eliminates the need for application-level retry logic
• C. Use the cloud free tier to host long-term production workloads
• D. A model for consuming technology services such as virtual machines, databases, and storage from a cloud provider

Cloud computing describes a service-consumption model for IT resources delivered by a provider.
