Security Center helps detect and mitigate security vulnerabilities but does not manage overall governance or compliance across Azure subscriptions.
C) Azure Monitor provides monitoring and logging capabilities for Azure resources, helping organizations track the performance and health of their cloud infrastructure. It can send alerts based on various metrics and logs, but it does not handle governance and policy management in the same way as Azure Policy. While Azure Monitor plays a key role in maintaining operational health, it does not define or enforce governance policies.
D) Azure Blueprints is a service that enables organizations to define and deploy a set of resources, including policies, role assignments, and resource templates, as part of a blueprint. While Azure Blueprints can help ensure consistent deployment of resources with pre-defined governance configurations, it is not primarily focused on enforcing ongoing compliance across multiple subscriptions. Azure Policy is a better fit for defining and enforcing governance policies on an ongoing basis.
Question 119:
Which Azure service is used to implement real-time stream processing and analytics for large-scale, high-velocity data such as logs, metrics, and telemetry?
A) Azure Stream Analytics
B) Azure Data Factory
C) Azure Databricks
D) Azure HDInsight
Answer: A)
Explanation:
A) Azure Stream Analytics is the correct answer. Azure Stream Analytics is a fully managed, real-time analytics service designed to process large volumes of streaming data. It allows you to perform real-time analysis on data coming from various sources such as IoT devices, logs, metrics, and telemetry. The service is optimized for low-latency and high-throughput, and it integrates well with other Azure services like Azure Event Hubs, Azure IoT Hub, and Azure Data Lake. Stream Analytics provides real-time insights and can output the results to other services for further processing or visualization, such as Power BI for dashboards.
B) Azure Data Factory is an extract, transform, and load (ETL) service designed for data integration and orchestration. While it is powerful for batch processing and data movement across multiple systems, it is not designed for real-time stream processing. Data Factory focuses on data workflows, whereas Stream Analytics is dedicated to real-time analytics.
C) Azure Databricks is an Apache Spark-based analytics platform that provides a collaborative environment for data engineering, machine learning, and data science. While Databricks can handle large datasets and supports real-time analytics, it is more suited for batch processing and machine learning workloads rather than dedicated real-time stream processing. Azure Stream Analytics is more appropriate for scenarios that require real-time processing of high-velocity data.
D) Azure HDInsight is a fully managed cloud service for big data processing, offering popular open-source frameworks like Hadoop, Spark, and Hive. It is ideal for large-scale data processing tasks but is not specifically designed for real-time stream processing. HDInsight is better suited for batch processing and big data workloads rather than real-time analytics.
Question 120:
Which Azure service allows you to deploy and manage Docker containers and Kubernetes clusters in a fully managed environment?
A) Azure App Service
B) Azure Container Instances
C) Azure Kubernetes Service
D) Azure Functions
Answer: C)
Explanation:
A) Azure App Service provides a platform for hosting web applications, APIs, and mobile backends, but it is not specifically focused on container orchestration. While Azure App Service can run Docker containers, it is not the best choice for managing and orchestrating multiple containers or Kubernetes clusters.
B) Azure Container Instances (ACI) is a service that allows you to run individual containers in a serverless environment. It is suitable for running simple, stateless workloads and short-term tasks. However, ACI does not offer the advanced container orchestration features that are required for managing large-scale applications with multiple containers or complex workloads.
C) Azure Kubernetes Service (AKS) is the correct answer. AKS is a fully managed Kubernetes service that allows you to deploy, manage, and scale containerized applications. Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and operation of application containers. Azure Kubernetes Service makes it easier to set up and manage Kubernetes clusters without the need for extensive manual configuration. AKS offers features like automatic scaling, integrated monitoring, and a simplified control plane, making it ideal for deploying and managing complex containerized applications at scale.
D) Azure Functions is a serverless compute service that enables you to run code in response to events. While Azure Functions can run in containers, it is not designed for container orchestration or management like Azure Kubernetes Service. It is better suited for lightweight, event-driven workloads rather than large-scale containerized applications.
