Microsoft Azure Fundamentals Practice Test (AZ-900)

Azure Monitor alerts let you create alert rules that continuously evaluate metrics or log-query results for your Azure resources. When the rule detects that a value crosses the threshold you defined, it fires and triggers an action group that can send email, SMS, push notifications, or run automation so your team is informed immediately.

Azure Monitor Logs (Log Analytics) is the repository that collects and organizes log data; you can base alert rules on this data, but Logs by itself does not send notifications.

Azure Monitor Metrics stores real-time numerical data for resources; like Logs, it requires an alert rule to generate notifications.

Application Insights focuses on application performance telemetry and offers its own smart-detection capabilities, but threshold-based notifications on resource metrics are still configured through Azure Monitor alerts.

Azure ExpressRoute provides a private connection to Azure services, bypassing the public internet. It is meant for scenarios where companies require a dedicated and reliable connection between their on-premises infrastructure and their Azure environment. ExpressRoute is designed for high-throughput and secure connections, which is ideal for hybrid cloud deployments. Other services mentioned, like VPN Gateway and Azure Front Door, offer connectivity options, but not with the same level of private, dedicated connection that ExpressRoute provides. VPN Gateway establishes secure, cross-premises connectivity over the public internet. Azure Front Door is a scalable and secure entry point for web applications but not meant for extending on-premises networks to the cloud.

This statement is false.

Resource groups in Azure are designed to be associated with a single subscription. Each resource group resides within one subscription and does not span multiple subscriptions.

While management groups allow organizations to manage multiple subscriptions collectively, resource groups are specific to one subscription, facilitating organized resource management and billing within that subscription.

Data transfer between Azure regions incurs charges. When data moves between services in different regions, Azure charges for the outbound data transfer, which can increase costs, especially with large data volumes. Data transfer within the same virtual network is free of charge. Inbound data transfer from the internet is also free. Assigning public IP addresses incurs a small charge, but it's generally minimal compared to inter-region data transfer.

In the shared responsibility model, the cloud service provider is responsible for managing the physical infrastructure of the cloud environment, including data centers, servers, and network hardware. Customers are responsible for managing the data, applications, and various configurations within the cloud services they consume, depending on the type of service (IaaS, PaaS, SaaS). For instance, in Infrastructure as a Service (IaaS), the customer is responsible for the OS, middleware, runtime, applications, and data, whereas the cloud provider manages the physical infrastructure, network, and virtualization layer.

The Azure Portal is a web-based, unified console that provides a graphical interface for managing and configuring Azure resources. It allows users to build, manage, and monitor everything from simple web apps to complex cloud deployments through an intuitive graphical interface.

Azure role-based access control (RBAC) is a system that allows you to assign roles to users, groups, or applications to control access to Azure resources. It provides fine-grained access management by allowing you to specify who can perform specific actions on Azure resources.

Azure Monitor is a service for collecting, analyzing, and acting on telemetry data from your Azure and on-premises resources. While it helps with performance and health monitoring, it does not provide role assignment or access control.

Azure Resource Manager (ARM) templates are JSON files that define the infrastructure and configuration of Azure resources. ARM templates allow for declarative deployment of resources but do not manage access control or permissions.

Azure Policy is a governance tool that allows you to create, assign, and manage policies that enforce rules on resources. It is used to ensure compliance with organizational standards but does not provide access control through role assignments.

Azure Service Health provides personalized notifications and guidance when Azure service issues, planned maintenance, or health advisories could affect your subscriptions and regions. You can configure Service Health alerts (through Azure Monitor) to receive these notifications via email, SMS, push, webhooks, and other channels.

Azure Monitor is the platform that collects and analyzes telemetry and hosts the alerting engine; although you create Service Health alerts there, the underlying service-level data still comes from Azure Service Health.

Azure Advisor offers best-practice recommendations to optimize cost, performance, reliability, security, and operational excellence but does not report Azure-wide incidents or maintenance events.

Azure Security Center (now Microsoft Defender for Cloud) focuses on cloud security posture management and threat detection rather than service-health notifications.

The correct answer is the benefit of adherence to regulatory compliance. Cloud providers often offer compliance with various industry standards and regulations, such as HIPAA for healthcare data, which is a critical requirement for organizations handling sensitive data. By choosing a cloud provider that adheres to these standards, the healthcare company can ensure that their patient data is protected according to necessary regulations. While encryption is indeed a security measure provided by many clouds, it is a feature rather than an overarching governance benefit. Enhanced physical security, although important, is a component of the overall security posture but is less specific to the regulatory data protection requirements than a formal compliance attestation. Cost savings, while a potential benefit of cloud services, is not primarily related to security and governance.

Deploying the VMs across Availability Zones ensures that your application remains operational even if an entire datacenter fails, as Availability Zones are physically separate locations within an Azure region. Each zone is an isolated location with independent power, cooling, and networking.

Availability Sets distribute VMs across fault and update domains within the same datacenter, so they do not protect against datacenter failures.

Scale Sets help deploy and manage a set of identical VMs for autoscaling but do not inherently provide high availability across datacenters.

Azure Virtual Desktop is a desktop and application virtualization service and is not relevant to this scenario.

Azure Role-Based Access Control (RBAC) allows administrators to control access to Azure resources by assigning roles to users, groups, and service principals. This enables fine-grained control over permissions, ensuring users have the necessary access to perform their tasks.

Azure Resource Locks are used to prevent accidental deletion or modification of resources. They add an additional layer of protection to resources by applying either "Read-only" or "Delete" locks, but they do not define specific permissions for performing actions on resources.

Azure Multi-Factor Authentication (MFA) enhances security by requiring users to verify their identity through additional factors like a phone app when signing in. While it strengthens access security, it does not define or enforce specific permissions for resource actions.

Azure Key Vault is used to securely store and manage secrets, keys, and certificates for applications. It is not used for setting permissions on resources, though it can help manage access to sensitive information.

Azure Resource Manager (ARM) templates enable the automation of Azure resource deployment using declarative JSON files that define the infrastructure and configuration. This approach allows for consistent, repeatable deployments and supports version control systems, enhancing collaboration and change tracking.

Azure Policy helps enforce organizational standards and compliance.

Azure Portal is a web-based interface for manual resource management.

Azure Monitor is used for monitoring and analyzing the performance of resources.

Azure Advisor provides personalized, proactive recommendations to help you optimize your Azure resources for reliability, security, performance, and cost. It analyzes your resource configuration and usage telemetry to offer best practices tailored to your deployments.

Azure Monitor focuses on collecting and analyzing telemetry data to monitor the performance and availability of your applications and services but does not provide optimization recommendations.

Azure Service Health informs you about service issues and planned maintenance but does not suggest improvements.

Azure Cost Management helps you monitor and control Azure spending but doesn't provide recommendations on reliability, security, or performance enhancements.

A Resource Group in Azure is a container that holds related resources for an application. It allows you to manage these resources as a single entity, making it easier to deploy, monitor, and apply policies across all the grouped resources.

Azure Cost Management provides tools to analyze and control Azure spending, allowing users to create budgets and set up alerts for when costs exceed specified limits. Azure Monitor focuses on collecting and analyzing operational telemetry data, not specifically on cost management. Azure Advisor offers personalized recommendations to optimize Azure deployments but does not provide budgeting features. Azure Policy helps enforce organizational standards and assess compliance at scale, rather than managing costs.
