Question 2mediummultiple choice
Full question →A company currently runs its application on-premises in a data center. The IT manager calculates that the cost per server per month is approximately $200 when considering hardware depreciation, electricity, cooling, and staff. The company is considering moving to Azure and discovers that Azure can provision the same server capacity for $150 per month, but only if the company commits to a three-year reservation. Which cloud concept best explains why Azure can offer a lower price even with the reservation commitment?
Question 3mediummultiple choice
Full question →A company deploys a mission-critical application across three Azure availability zones. The application is designed to continue operating without any interruption if an entire availability zone becomes unavailable. Which cloud computing characteristic does this scenario best illustrate?
Question 4mediummultiple choice
Full question →A cloud provider uses virtualization technology to host multiple customers on the same physical server. Each customer's data, applications, and operating systems are logically isolated and secured from one another. Which characteristic of cloud computing does this scenario best describe?
Question 5easymultiple choice
Full question →A bank needs to keep some sensitive customer data on-premises due to regulatory requirements, but wants to use cloud services for less sensitive workloads. Which cloud deployment model should they adopt?
Question 6mediummultiple choice
Full question →A company currently runs its IT operations entirely on-premises. The finance team is evaluating moving to Azure and wants to understand the financial impact. They currently purchase new servers every five years as a large upfront capital expenditure (CapEx). In Azure, they would pay a fixed monthly subscription for virtual machines instead. This shift from a large upfront payment to a smaller monthly operational expense (OpEx) is a direct illustration of which cloud computing benefit?
Question 7mediummultiple choice
Full question →A company has a root management group that contains all Azure subscriptions. A centralized governance team needs to create and assign Azure Policy definitions and set initiatives that apply to all subscriptions. Which built-in role should be assigned to the governance team at the root management group scope to grant the minimum required permissions?
Question 8mediummultiple choice
Full question →A company has deployed multiple Azure virtual machines for a production workload. The IT administrator wants a centralized list of prioritized recommendations to improve the security, high availability, and cost efficiency of the virtual machines. The administrator also wants to be able to view the potential impact of implementing each recommendation. Which Azure service should the administrator use?
Question 9easymultiple choice
Full question →A company currently budgets for maximum capacity to handle peak loads, resulting in underutilized resources during off-peak times. They want a model where they can quickly adjust resources up or down based on demand. Which cloud characteristic directly addresses this concern?
Question 10mediummultiple choice
Full question →A company has multiple on-premises file servers that store user home directories and department shares. The company wants to migrate these file shares to Azure Files to eliminate on-premises server maintenance. However, users frequently access large files, and the company wants to cache the most frequently accessed files locally on a small Windows Server machine at each branch office to minimize latency and bandwidth usage. The company also wants a single unified namespace so users can access files using the same path regardless of whether the files are cached locally or stored in Azure. Which Azure service should the company use?
Question 11mediummultiple choice
Full question →A company has traditionally managed on-premises servers for their internal business applications. Setting up a new test environment involves ordering hardware, waiting for delivery, racking, and configuring the OS and applications, which typically takes two to three weeks. The company is migrating their development and testing workloads to Azure. Now, developers can deploy a complete, pre-configured test environment using Azure Resource Manager templates in under two hours. This ability to rapidly provision resources and adapt to changing requirements best illustrates which benefit of cloud computing?
Question 12easymultiple choice
Full question →A company can provision virtual machines in Azure without submitting a request or waiting for hardware procurement. Which cloud characteristic does this describe?
Question 13mediummultiple choice
Full question →A company deploys an Azure SQL Database. The company is billed based on the amount of data stored and the number of transactions per second (DTUs). At the end of each month, the company receives an invoice that itemizes the exact usage and the corresponding charges. Which of the five essential characteristics of cloud computing does this billing model primarily demonstrate?
Question 14mediummultiple choice
Full question →A company historically purchased physical servers and networking equipment for its data center, paying the full cost upfront before using the hardware. The company is now migrating its workloads to Azure and will only pay for the compute and storage resources it consumes each month, with no long-term commitments or upfront hardware purchases. This financial model change best represents which cloud computing benefit?
Question 15mediummultiple choice
Full question →A company has multiple Azure subscriptions used by different departments. The security team wants to enforce a requirement that all Azure Storage accounts in every subscription must be encrypted at rest using customer-managed keys (CMK). The solution must automatically evaluate existing and new storage accounts for compliance, and it must be able to automatically remediate non-compliant resources by enabling CMK encryption. The team wants to use a single, centralized Azure feature that can be assigned once and apply to all subscriptions. Which Azure feature should they use?
Question 16mediummultiple choice
Full question →A company has a legacy on-premises application that processes sensitive financial data. Due to regulatory requirements, certain data cannot leave the company's on-premises data center. However, the company wants to take advantage of the cloud's scalability for the application's compute-intensive batch processing jobs. The batch jobs need to access the sensitive data but must process it without the data ever being stored in the cloud. The batch jobs will be orchestrated from the cloud. Which cloud deployment model best describes this architecture?
Question 17mediummultiple choice
Full question →A company hosts a web application on a single Azure virtual machine. Over the past month, the application's CPU utilization has consistently remained above 90%, causing slow response times. The administrator plans to modify the virtual machine's size from Standard_D2s_v3 (2 vCPUs) to Standard_D8s_v3 (8 vCPUs) to improve performance. Which scaling method does this change represent?
Question 18mediummultiple choice
Full question →A cloud provider purchases hardware in bulk and shares physical infrastructure among many customers, which allows them to offer lower prices per customer. This benefit is known as:
Question 19hardmultiple choice
Full question →A company is evaluating cloud providers. They want to ensure that their data remains within a specific country due to legal requirements. Which cloud computing concept is most directly related to this requirement?
Question 20easymultiple choice
Full question →A cloud provider offers resources on-demand and measures usage. Customers pay only for what they consume. Which characteristic of cloud computing is this?
Watch out for
Common Describe Cloud Concepts exam traps
- ▸IaaS gives you infrastructure control; SaaS gives you only the application.
- ▸Hybrid cloud combines on-premises and public cloud — not two public clouds.
- ▸Cloud does not automatically mean cheaper or more secure.
- ▸Management responsibility shifts with each service model (IaaS → PaaS → SaaS).
