C) Azure Bastion
D) NSGs

Answer:
A

Explanation:

VPN Gateway with BGP enabled provides secure, encrypted site-to-site connectivity between Azure VNets and on-premises networks. Enabling BGP allows dynamic propagation of routing information, reducing the need for manual configuration and ensuring that routes are updated automatically in response to network topology changes. This dynamic routing also supports automatic failover, providing high availability if a primary connection fails. By using VPN Gateway with BGP, multiple VNets can communicate with on-premises networks efficiently and securely, with minimal operational overhead.

Option B, ExpressRoute, provides private, high-bandwidth connectivity with predictable performance. While ExpressRoute offers excellent reliability and high throughput, it does not inherently support automatic routing between VNets and on-premises networks unless combined with additional routing mechanisms. ExpressRoute is often deployed for scenarios requiring dedicated, low-latency connections, but it may require more operational management to achieve dynamic failover across multiple VNets.

Option C, Azure Bastion, is designed for secure RDP/SSH access to VMs without exposing public IP addresses. While Bastion enhances security for VM management, it does not provide connectivity between VNets or to on-premises networks, and therefore does not satisfy requirements for high-availability hybrid network routing.

Option D, NSGs, are used to enforce security rules and segment traffic at the subnet or NIC level. While crucial for controlling communication and limiting exposure, NSGs do not provide connectivity or dynamic routing capabilities.

Deploying VPN Gateway with BGP allows an enterprise to maintain encrypted, secure connections with automatic routing updates and failover support. This approach reduces the risk of misconfigurations and ensures business continuity by allowing traffic to reroute automatically during outages. BGP also simplifies network management in large-scale hybrid environments by automating route propagation and improving operational efficiency.

This configuration aligns with enterprise best practices for scalable, resilient hybrid networking.VPN Gateway with BGP enabled serves as a critical component in hybrid network architectures. It establishes a secure, encrypted tunnel between on-premises networks and Azure Virtual Networks (VNets). Unlike static routing solutions, the dynamic routing provided by BGP ensures that network paths are updated automatically whenever there is a change in the network topology. This eliminates the need for manual configuration, which is often error-prone, and provides a seamless experience for network administrators managing multiple VNets and on-premises sites. By ensuring that the VPN Gateway can dynamically adjust to changes, enterprises achieve both operational efficiency and high reliability in their hybrid networks.

Dynamic Routing and High Availability

BGP allows the VPN Gateway to exchange routing information with on-premises routers, enabling automatic detection of new routes or changes to existing ones. This dynamic behavior is crucial for maintaining high availability because if a primary VPN tunnel goes down, traffic can automatically reroute through alternative paths. In large-scale enterprises, where multiple branches and VNets are interconnected, this automatic failover prevents downtime and ensures continuous connectivity. Additionally, BGP supports load balancing across multiple paths, which optimizes bandwidth utilization and reduces the risk of congestion on any single route.

Simplifying Hybrid Network Management

Managing hybrid networks without dynamic routing can be complex, especially when there are multiple VNets, subnets, and on-premises sites. VPN Gateway with BGP simplifies this complexity by propagating routes automatically and updating network tables in real-time. This reduces administrative overhead and the likelihood of misconfigurations, which can lead to network outages or security vulnerabilities. Enterprises can focus on higher-level network design and policy enforcement rather than constantly updating routing tables manually. The integration of monitoring tools allows administrators to track routing changes, detect failures early, and respond proactively to potential issues.

Comparison with Other Azure Networking Services

Azure Traffic Manager is a DNS-based global traffic routing solution that directs users to the closest or healthiest endpoint. Traffic Manager supports multiple routing methods, including performance-based, geographic, priority, and weighted routing. By continuously monitoring endpoint health, Traffic Manager automatically reroutes traffic if an endpoint becomes unavailable, ensuring minimal downtime and optimized performance for global users.

Option B, Application Gateway, provides regional layer 7 load balancing and WAF protection for HTTP/HTTPS traffic but does not support global DNS-based routing or failover. It cannot optimize performance across multiple regions or provide disaster recovery capabilities.

Option C, Standard Load Balancer, distributes traffic at layer 4 within a single region but cannot perform global routing, endpoint selection based on proximity, or reroute traffic in case of failures.

Option D, Azure Firewall, inspects and filters traffic but does not provide routing to the closest endpoint or optimize performance for users. Its focus is security enforcement rather than global traffic management.

Deploying Azure Traffic Manager ensures users are automatically directed to the nearest available endpoint, reducing latency and improving responsiveness. It provides high availability, supports multi-region deployments, and enables disaster recovery by rerouting traffic during outages. Traffic Manager improves operational continuity, optimizes user experience, and supports enterprise-grade applications with global reach. By integrating with monitoring tools, organizations can gain insights into endpoint performance, availability, and traffic patterns, enhancing operational decision-making and ensuring reliable delivery of services worldwide.
