It also provides automatic scaling, security, and workload management to ensure optimal performance and cost-efficiency.
C) Azure SQL Database is a fully managed relational database service, but it is not designed specifically for data warehousing. It is more suitable for transactional workloads or applications that require an SQL-based database engine. While SQL Database can handle smaller data sets, it lacks the high performance and scalability features needed for large-scale data warehousing.
D) Azure Cosmos DB is a globally distributed, multi-model NoSQL database designed for high-availability and low-latency applications. While it excels in scenarios requiring high throughput and low latency for globally distributed data, it is not a traditional data warehousing service and is more suited for NoSQL workloads.
Question 198:
Which Azure service provides a fully managed, serverless, and scalable event streaming platform for building real-time applications?
A) Azure Event Hubs
B) Azure Service Bus
C) Azure Event Grid
D) Azure Stream Analytics
Answer: A)
Explanation:
A) Azure Event Hubs is the correct answer. Azure Event Hubs is a fully managed, serverless event streaming platform that allows you to ingest millions of events per second and process them in real-time. Event Hubs is designed to handle large-scale event-driven architectures and stream data from a variety of sources to various consumers for processing, analytics, and storage.
Event Hubs provides high throughput and low-latency capabilities, making it ideal for use cases such as telemetry data ingestion, real-time analytics, and event-driven applications. It is fully managed, meaning Azure takes care of the scaling, infrastructure, and availability, and it is highly integrated with other Azure services like Azure Stream Analytics, Azure Functions, and Azure Databricks for processing and analyzing events in real time.
B) Azure Service Bus is a messaging service designed for reliable and asynchronous communication between applications. While it supports messaging patterns such as queues and topics, it is not designed for high-throughput event streaming like Event Hubs. Service Bus is better suited for scenarios where message reliability and guaranteed delivery are required, such as decoupling application components.
C) Azure Event Grid is an event routing service that facilitates event-driven architectures by enabling the routing of events from various Azure services to event handlers like Azure Functions, Logic Apps, or custom webhooks. While Event Grid is excellent for event distribution, it does not offer the same high-throughput streaming capabilities as Event Hubs.
D) Azure Stream Analytics is a real-time data stream processing service that allows users to process and analyze data streams from sources like Event Hubs or IoT devices. It is typically used for real-time data analysis and visualization but is not itself an event streaming platform. Stream Analytics is used in conjunction with Event Hubs or other event sources for processing real-time data.
Question 199:
Which Azure service provides a scalable, high-performance file storage solution for applications that need shared access to files across multiple virtual machines?
A) Azure Blob Storage
B) Azure Disk Storage
C) Azure File Storage
D) Azure Data Lake Storage
Answer: C)
Explanation:
A) Azure Blob Storage is a service designed for storing unstructured data in the form of objects or blobs, such as images, videos, and backup files. While Blob Storage is highly scalable and cost-effective, it does not provide a file-sharing mechanism for applications to access files across multiple virtual machines in the same way that Azure File Storage does.
B) Azure Disk Storage is designed for storing persistent block-level data for virtual machines. It is not suitable for scenarios where you need shared access to files across multiple virtual machines. Disk Storage is ideal for virtual machine disks, databases, and workloads that require high-performance block storage.
C) Azure File Storage is the correct answer. Azure File Storage provides fully managed file shares that can be accessed using the Server Message Block (SMB) protocol. This makes it suitable for scenarios where applications need shared access to files from multiple virtual machines or across different applications. Azure File Storage is perfect for lift-and-shift scenarios where you need to move applications that rely on shared file storage into the cloud.
Azure File Storage supports features like automatic scaling, redundancy, and secure access control, making it an excellent choice for storing application data, log files, configuration files, and other types of shared resources in the cloud.
D) Azure Data Lake Storage is designed for big data analytics and is optimized for storing large amounts of structured and unstructured data. It is not specifically designed for file-sharing scenarios across multiple virtual machines, which makes Azure File Storage a better fit for those use cases.
Question 200:
Which Azure service is designed for managing and storing secrets, keys, and certificates in a secure manner?
A) Azure Key Vault
B) Azure Active Directory
C) Azure Security Center
D) Azure Firewall
Answer: A)
Explanation:
A) Azure Key Vault is the correct answer. Azure Key Vault is a cloud service for securely storing and managing sensitive information such as API keys, passwords, certificates, and encryption keys. Key Vault helps protect your data by enabling secure access controls and providing logging capabilities to track the use of secrets, keys, and certificates.
