Free Practice Questions for EMC D-VXB-DY-A-24 Exam

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.

Understand SDN Architecture: In a Software Defined Network (SDN), separating the control plane from the data plane allows for centralized management of the network1.

Recognize the Control Plane’s Role: The control plane is responsible for making decisions about where traffic is sent, while the data plane moves packets from place to place1.

Identify the Advantage: The main advantage of this separation is the ability to programmatically control both physical and virtual network devices, which enables more flexible and dynamic network management1.

Apply SDN Benefits: This programmatic control facilitates rapid changes to network configurations, policies, and security, which can be applied consistently across the entire network1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document outlines the benefits of SDN, including the programmatic control that comes with separating the control and data planes1.
