AZ-900 Practice Test 22 — 15 Questions

Question 1

What are the two types of Azure Resource Locks?

Accepted Answer

CanNotDelete and ReadOnly. Azure Resource Locks are designed to prevent accidental deletion or modification of critical resources. The two types are CanNotDelete, which allows read and update operations but blocks deletion, and ReadOnly, which permits only read operations and blocks both deletion and update. This distinction is correct because ReadOnly is more restrictive than CanNotDelete, and both are the only lock types available in Azure.

Answer

ReadOnly and ReadWrite

Answer

Shared and Exclusive

Answer

Deny and Allow

Answer

Azure Event Hubs

Answer

Azure Monitor Alerts

Question 6

What is the main benefit of cloud computing's 'economies of scale' for customers?

Accepted Answer

Customers benefit from lower costs because the provider buys at massive scale. Economies of scale in cloud computing means that cloud providers like Microsoft Azure purchase vast amounts of hardware, networking equipment, and power at significantly reduced per-unit costs due to bulk buying. These savings are passed down to customers in the form of lower pay-as-you-go prices, making cloud services more affordable than if each customer had to procure and maintain their own infrastructure.

Answer

Customers can use unlimited resources without any cost

Answer

All customers get the same hardware regardless of need

Answer

Cloud providers always have the latest hardware immediately

Question 7

A company uses Azure SQL Database (PaaS). According to the shared responsibility model, who is responsible for applying security patches to the underlying operating system that runs the database service?

Accepted Answer

Microsoft. Microsoft is responsible for applying security patches to the underlying operating system that hosts Azure SQL Database because it is a Platform as a Service (PaaS) offering. In the PaaS shared responsibility model, the cloud provider manages the infrastructure, including the OS, runtime, and network, while the customer is responsible for data and access management. Azure SQL Database abstracts the OS layer entirely, so Microsoft handles all patching and maintenance to ensure security and compliance.

Answer

The customer

Answer

Both

Answer

Neither

Question 8

A company wants to replicate its on-premises production environment to Azure for disaster recovery purposes. In the event of an on-premises outage, they can quickly start the replicated environment in Azure. Which cloud benefit does this best describe?

Accepted Answer

Business continuity. This scenario describes business continuity (C), which ensures that an organization can continue operations during and after a disaster. By replicating the on-premises environment to Azure and enabling rapid startup in the event of an outage, the company is implementing a disaster recovery (DR) strategy—a core component of business continuity. Azure Site Recovery (ASR) is the specific service that orchestrates replication, failover, and failback to meet recovery time objectives (RTO) and recovery point objectives (RPO).

Answer

Scalability

Answer

High availability

Answer

Elasticity

Question 9

Which Azure feature allows administrators to set a maximum spending limit to prevent unexpected charges on a subscription?

Accepted Answer

Azure Cost Management budgets. Azure Cost Management budgets allow administrators to set spending limits and receive alerts when costs exceed thresholds, preventing unexpected charges. This feature directly controls subscription spending by defining budget amounts and actions, such as disabling resources or sending notifications, when the budget is reached.

Answer

Azure Policy

Answer

Azure Reservations

Answer

Azure Advisor cost recommendations

Question 10

What happens when an Azure subscription reaches its spending limit?

Accepted Answer

Azure services are stopped and deallocated until the limit is removed or reset. When an Azure subscription reaches its spending limit, Azure suspends the subscription, stopping and deallocating all running services. This prevents any further charges beyond the configured budget. The limit must be removed or reset to resume services; no automatic increase occurs.

Answer

Azure automatically increases the subscription limit to handle additional charges

Answer

Azure notifies the account owner but continues running services

Answer

All data is permanently deleted to prevent additional storage charges

Question 11

A company wants to monitor the performance of their Azure VMs and receive alerts when CPU usage exceeds 90%. Which Azure service should they use?

Accepted Answer

Azure Monitor. Azure Monitor is the correct service because it provides a comprehensive solution for collecting, analyzing, and acting on telemetry from Azure resources, including VMs. It includes metrics like CPU percentage and allows you to configure metric alerts that trigger when a threshold (e.g., 90% CPU usage) is exceeded. This directly meets the requirement for performance monitoring and alerting.

Answer

Question 13

A company wants to ensure its Azure resources are deployed in a geographic location that is paired with another region for disaster recovery. If a regional outage occurs, they plan to failover to the paired region. Which concept does this describe?

Accepted Answer

Azure region pairs. Azure region pairs are designed to support disaster recovery by ensuring that each Azure region is paired with another region in the same geography (e.g., East US paired with West US). During a regional outage, services can failover to the paired region, and Microsoft prioritizes recovery of paired regions to minimize downtime. This concept directly matches the scenario described, where the company plans to use a paired region for failover.

Answer

Availability zones

Answer

Azure geographies

Answer

Sovereign regions

Question 14

A company wants to estimate the cost of a new Azure solution before deploying it. Which tool should they use?

Accepted Answer

Azure Pricing Calculator. The Azure Pricing Calculator is the correct tool because it allows users to estimate the cost of Azure services by configuring specific resources (e.g., VMs, storage, networking) with their desired settings (region, tier, quantity) before deployment. This provides a detailed, itemized cost projection based on current pay-as-you-go or reserved pricing, enabling informed budgeting without incurring actual charges.
