A. Azure ExpressRoute
B. Azure Front Door
C. Azure VPN Gateway
D. Azure Virtual Network Peering
E. Azure Bastion
Answer
D. Azure Virtual Network Peering
Explanation
Azure VNet Peering enables low-latency, high-bandwidth communication between virtual networks in different regions.
The Azure networking service that allows virtual networks (VNets) in different Azure regions to communicate securely with low-latency connections is Azure Virtual Network Peering.
Azure Virtual Network Peering enables seamless, private connectivity between two or more VNets, treating them as a single network for connectivity purposes. This can be done within the same region (local peering) or across different Azure regions (global peering).
Global VNet Peering specifically allows VNets in different Azure regions to communicate directly over the Microsoft backbone network, ensuring low-latency, high-bandwidth, and secure connections without traversing the public internet.
- Security: All traffic between peered VNets stays on the Microsoft backbone, isolated from the public internet. No VPN gateways, public endpoints, or additional encryption are required to maintain privacy and security.
- Performance: The latency and throughput between virtual machines in peered VNets are comparable to those within a single VNet, supporting high-performance and real-time workloads.
- Simplicity: Peering is straightforward to configure and does not require downtime or complex routing. Network security groups (NSGs) can be used to further control access between peered VNets.
- Scalability: You can peer hundreds of VNets, supporting large-scale, multi-region architectures.
Azure Virtual Network Peering enables secure, low-latency, high-bandwidth communication between VNets in different Azure regions by privately routing traffic over the Microsoft backbone network, making it the recommended solution for cross-region VNet connectivity.
