It is excellent for processing large-scale data and building machine learning models, but it is not a fully managed service for deploying machine learning models at scale. While you can use Databricks to train models, it lacks the extensive deployment and model tracking capabilities offered by Azure Machine Learning.
C) Azure Cognitive Services provides a suite of pre-built AI models for tasks such as vision, speech, language, and decision-making. While Cognitive Services allows you to integrate AI capabilities into applications without custom model development, it is not intended for building, tracking, or deploying machine learning models at scale. Azure Machine Learning is better suited for the full machine learning lifecycle, including deployment and monitoring of custom models.
D) Azure Synapse Analytics is a unified analytics service that combines big data and data warehousing capabilities. It is used for data processing, analytics, and running data pipelines, but it is not focused on building or deploying machine learning models. While Synapse can integrate with machine learning services like Azure Machine Learning, it does not offer the same end-to-end machine learning deployment and monitoring capabilities as Azure Machine Learning.
Question 79:
Which Azure service allows you to create and manage virtual networks, configure subnets, and establish secure connections between on-premises infrastructure and Azure?
A) Azure Virtual Network (VNet)
B) Azure Load Balancer
C) Azure Traffic Manager
D) Azure Application Gateway
Answer: A)
Explanation:
A) Azure Virtual Network (VNet) is the correct answer. Azure VNet is the fundamental building block for creating a secure and isolated network within Azure. It allows you to create subnets, assign IP addresses, configure network security groups (NSGs), and set up VPN or ExpressRoute connections to establish secure communication between on-premises infrastructure and Azure resources. VNet is used to create a virtual network that connects resources like virtual machines (VMs), containers, and services, providing complete network isolation and control over traffic.
B) Azure Load Balancer is a service used to distribute incoming network traffic across multiple resources, such as virtual machines or instances, within an Azure VNet. While it ensures high availability by balancing traffic, it does not provide the functionality to create and manage virtual networks, subnets, or secure connections. VNet is the correct service for managing networks and securely connecting to on-premises environments.
C) Azure Traffic Manager is a DNS-based traffic routing service that enables you to distribute traffic across different endpoints, including Azure and non-Azure resources. It can be used for routing traffic based on geographical location or endpoint health, but it does not provide the network management features that VNet offers. Traffic Manager is more suited for global traffic distribution rather than creating and managing virtual networks.
D) Azure Application Gateway is a web traffic load balancer that provides application-level routing and load balancing. It is used for HTTP/HTTPS traffic and supports features like SSL termination, URL-based routing, and Web Application Firewall (WAF). While it can be used in conjunction with Azure VNet for traffic management, it is not used to create or manage virtual networks or secure connections to on-premises resources.
Question 80:
Which Azure service provides a fully managed, highly scalable data warehouse solution that enables you to analyze large datasets using SQL-based queries?
A) Azure SQL Database
B) Azure Synapse Analytics
C) Azure Cosmos DB
D) Azure Data Lake Storage
Answer: B)
Explanation:
A) Azure SQL Database is a fully managed relational database service designed for transactional workloads and small to medium-scale data storage and processing. While it supports SQL queries, it is not a data warehouse solution designed to handle massive datasets and complex analytical workloads. Azure Synapse Analytics is better suited for large-scale data warehousing and analytics.
B) Azure Synapse Analytics is the correct answer. Azure Synapse Analytics (formerly SQL Data Warehouse) is a fully managed cloud data warehouse service that allows you to store and analyze large datasets using SQL-based queries. It integrates with big data technologies like Apache Spark and Azure Data Lake to support both relational and non-relational data analysis. Synapse Analytics is highly scalable and designed to handle complex analytical workloads, making it the ideal service for organizations needing advanced data warehousing capabilities.
C) Azure Cosmos DB is a globally distributed, multi-model NoSQL database service. While it offers low-latency access and scalability for various NoSQL models, it is not designed for data warehousing or complex SQL-based analytics. Cosmos DB is more suitable for operational databases with high throughput requirements, not large-scale analytical workloads.
D) Azure Data Lake Storage is a scalable and secure data lake service for storing massive amounts of unstructured data. While it is excellent for data storage and big data analytics, it does not offer the built-in SQL querying capabilities or data warehousing features that Azure Synapse Analytics provides. Data Lake Storage is often used as a data repository for raw data, while Synapse Analytics is used for data processing and analytics.
