Understand VxLAN: VxLAN, or Virtual Extensible LAN, is a network virtualization technology that encapsulates Layer 2 Ethernet frames within Layer 3 UDP packets1.
Identify Encapsulation Process: This encapsulation allows for the creation of a virtualized Layer 2 network over an existing Layer 3 infrastructure, enabling greater scalability and flexibility in network design1.
Recognize VxLAN Functionality: By encapsulating Layer 2 frames in UDP packets, VxLAN extends Layer 2 networks over Layer 3 networks, which is particularly useful in cloud computing and data center environments1.
Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with this understanding of VxLAN, highlighting its role in network virtualization and the encapsulation process1.
Questions # 22:
What is a key benefit VxLAN?
Options:
A.
It reduces implementation cost of multiple VxBlock systems sharing data centers.
B.
It enables vMotion over Layer 3 subnets across geographic locations.
C.
It enables inter-VM communications among data center servers in different Layer 2 subnets.
D.
It can be configured in the hypervisor to support an NSX implementation.
Understand VxLAN: VxLAN, or Virtual Extensible LAN, is a network virtualization technology that allows for the creation of a Layer 2 network on top of a Layer 3 network1.
Identify Key Benefit: One of the key benefits of VxLAN is that it enables vMotion to occur over Layer 3 subnets, which can span across different geographic locations1.
Recognize VxLAN Capabilities: By encapsulating Layer 2 Ethernet frames into Layer 4 UDP packets, VxLAN allows for the extension of networks over long distances, facilitating vMotion in environments where the physical network infrastructure is spread out1.
Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with this understanding of VxLAN, highlighting its ability to support vMotion across Layer 3 subnets as a significant advantage1.
