EMC D-VXB-DY-A-24 Exam With Confidence Using Practice Dumps

Review VMKernel NIC Functions: The VMKernel NIC in VMware vSphere provides network connectivity for hosts and handles system traffic for various services1.

Identify vMotion Service: Among the services provided by the VMKernel NIC, vMotion is a key feature that allows for the live migration of virtual machines from one host to another without downtime1.

Understand vMotion: vMotion requires network connectivity to transfer the memory and state of a virtual machine.The VMKernel NIC facilitates this connectivity and ensures the seamless migration of VMs1.

Reference VMware Documentation: VMware documentation confirms that the VMKernel NIC handles system traffic for vMotion, among other services1.

To verify that the hosts can communicate with XtremIO in a VxBlock 1000, you can power off a ToR (Top of Rack) switch. This test helps ensure that network redundancy and failover mechanisms are working correctly, confirming that communication is maintained through alternative paths.

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.
