20+ practice questions focused on Describe cloud concepts — one of the most tested topics on the Microsoft Azure Fundamentals AZ-900 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Describe cloud concepts PracticeA company wants to ensure that its cloud resources are available even if a major disaster occurs in one region. They plan to deploy resources in two different geographic locations. Which cloud computing characteristic does this scenario primarily address?
Explanation: High availability (HA) is correct because the scenario explicitly describes deploying resources in two different geographic locations to ensure that the cloud resources remain available even if a major disaster occurs in one region. HA focuses on minimizing downtime by providing redundant resources across locations, including multi-region deployments. Disaster recovery (DR), on the other hand, focuses on restoring services and data after a catastrophic failure, often involving backups and recovery plans, not necessarily continuous availability. Since the goal is to keep resources available before and during the disaster, HA is the primary characteristic addressed.
A company runs several virtual machines on Azure that are hosted on physical servers shared with other customers. The company is concerned that another customer's high workload ('noisy neighbor') could degrade their own application performance. However, Azure's infrastructure ensures that each virtual machine receives a dedicated allotment of CPU and memory resources, and performance remains consistent regardless of the activity of other tenants. Which characteristic of cloud computing does this scenario best illustrate?
Explanation: Resource pooling is the correct answer because it describes how Azure's multi-tenant architecture allows physical resources (CPU, memory, storage, network) to be shared among multiple customers while ensuring each virtual machine receives a dedicated allocation of resources. This isolation prevents a 'noisy neighbor' scenario from degrading performance, as each VM's resource allotment is guaranteed regardless of other tenants' activity.
A financial services company has an on-premises data center that houses sensitive customer data. Regulatory requirements mandate that this data cannot be stored or processed outside the company's physical premises. However, the company wants to take advantage of cloud computing for compute-intensive risk analysis workloads that process anonymized subsets of the data. The company also needs to maintain a consistent management and security posture across both environments. Which cloud deployment model should the company adopt?
Explanation: Hybrid cloud is correct because it allows the company to keep sensitive customer data on-premises to meet regulatory requirements while leveraging the public cloud for compute-intensive risk analysis on anonymized subsets. This model also enables consistent management and security policies across both environments through unified tools like Azure Arc.
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?
Explanation: The shift from a large upfront capital expenditure (CapEx) for on-premises servers to a monthly operational expense (OpEx) for Azure virtual machines directly illustrates the consumption-based pricing model, a key cloud benefit. This model converts capital costs into recurring operational costs, enabling better cash flow management and budget predictability.
A company runs a batch job every night that takes 4 hours and cannot be interrupted. Which VM pricing model provides the lowest cost for this workload?
Explanation: Pay-as-you-go pricing is the most cost-effective for a nightly 4-hour batch job because it charges only for the time the VM runs, without requiring an upfront commitment. Reserved Instances are designed for always-on workloads; using them for only 4 hours per night would waste the paid capacity during idle hours, making Pay-as-you-go cheaper for intermittent usage.
