Explanation:
A) Azure Cosmos DB is the correct answer. Azure Cosmos DB is a fully managed, globally distributed NoSQL database service that is designed for high availability, low-latency operations, and scalability. It is ideal for applications that require fast, real-time read and write operations, such as e-commerce platforms, gaming backends, IoT solutions, and more.
Cosmos DB supports multiple data models, including document (MongoDB), key-value (Redis), column-family (Cassandra), and graph (Gremlin) databases, making it a versatile choice for different types of workloads. It provides automatic, global replication across multiple regions and offers multiple consistency models, including strong, bounded staleness, session, and eventual consistency.
Cosmos DB is built to handle massive amounts of data and can scale elastically to accommodate growing workloads. It also offers features like automatic indexing, partitioning, and the ability to query data using familiar APIs (such as SQL, MongoDB, Cassandra, etc.).
B) Azure SQL Database is a relational database service that supports structured data and is ideal for OLTP (online transaction processing) workloads. While it is powerful, it is not designed for the high-performance, globally distributed applications that Azure Cosmos DB is built for.
C) Azure Data Lake Storage is an enterprise-grade data lake that is optimized for storing large amounts of unstructured and structured data. It is used for big data analytics but is not a NoSQL database like Azure Cosmos DB.
D) Azure Table Storage is a NoSQL key-value store that offers scalability and fast access to unstructured data. While it is useful for certain scenarios, it lacks the rich features and performance of Azure Cosmos DB for globally distributed applications.
Question 60:
Which of the following Azure services is used to enable secure access to applications and resources in an Azure Virtual Network from on-premises or remote clients, using a site-to-site or point-to-site VPN connection?
A) Azure VPN Gateway
B) Azure ExpressRoute
C) Azure Application Gateway
D) Azure Traffic Manager
Answer: A) Azure VPN Gateway
Explanation:
A) Azure VPN Gateway is the correct answer. Azure VPN Gateway is a service that provides secure, encrypted communication between on-premises networks and Azure Virtual Networks (VNets) over the public internet. It supports both site-to-site VPN connections, which connect entire networks, and point-to-site VPN connections, which connect individual client devices to the Azure VNet.
Azure VPN Gateway uses IPsec and IKE protocols to provide secure data transmission. It can be used for hybrid cloud architectures where on-premises resources need to securely access resources in Azure, or for remote workers who need secure access to corporate resources hosted in Azure.
The VPN Gateway also supports route-based and policy-based connections, and it can integrate with Azure Network Security features such as Network Security Groups (NSGs) and Azure Firewall.
B) Azure ExpressRoute is a private, dedicated connection between on-premises data centers and Azure, providing a more reliable and lower-latency alternative to public internet connections. While it offers higher performance than a VPN connection, it is not designed for remote access or simple site-to-site VPNs.
C) Azure Application Gateway is a web traffic load balancer that helps manage and optimize web application traffic. It is primarily focused on application-level load balancing, such as routing HTTP and HTTPS traffic to backend servers. It does not handle secure site-to-site or point-to-site VPN connections.
D) Azure Traffic Manager is a global traffic distribution service that directs client traffic to the most appropriate endpoint based on performance, geographic location, or other criteria. While it helps with traffic routing, it does not provide secure network connectivity between on-premises resources and Azure like Azure VPN Gateway does.
