Question No. 1

Which NSX VMs run in the VxBlock AMP cluster?

Show Answer Hide Answer
Correct Answer: C

Review VxBlock System Documentation: The VxBlock System documentation provides detailed information on the integration of VMware NSX within the VxBlock AMP cluster1.

Identify NSX Components: The NSX Manager is the centralized network management component, and NSX Controllers are part of the control plane that manages the network state1.

Understand AMP Cluster Role: The Advanced Management Platform (AMP) cluster within a VxBlock system is designed to host critical management components, including those for NSX1.

Confirm with Official Dell EMC Resources: The Official Dell VxBlock Deploy Achievement document and other Dell EMC resources confirm that the NSX Manager and NSX Controllers run within the VxBlock AMP cluster1.


Question No. 2

A standard virtual switch is deployed on an ESXi host. Four virtual machines are connected to the vSwitch, which has no uplink ports configured.

Which statement is accurate about network connectivity between the VMs?

Show Answer Hide Answer
Correct Answer: A

Understand vSwitch Functionality: A standard virtual switch (vSwitch) operates at the data link layer of the OSI model to connect virtual machines on the same ESXi host2.

Recognize vSwitch without Uplinks: When a vSwitch has no uplink ports configured, it cannot communicate with external networks, but it can still facilitate communication between VMs connected to it1.

Identify VM Communication: The VMs connected to the vSwitch without uplinks can communicate with each other, as the vSwitch can bridge traffic internally between VMs on the same VLAN2.

Exclude External Communication: Without uplinks, the VMs cannot communicate with outside networks, regardless of whether Cisco Discovery Protocol (CDP) is used2.


Question No. 3

Which NSX component communicates with the VTEP?

Show Answer Hide Answer
Correct Answer: B

Identify the VTEP's role: The VTEP, or VXLAN Tunnel Endpoint, is responsible for encapsulating and de-encapsulating the network traffic sent over the VXLAN1.

Understand NSX Components: The NSX Controller is a key component of the VMware NSX network virtualization platform. It is responsible for the control plane, managing the state of virtual networks and overlay transport zones1.

Communication with VTEP: The NSX Controller communicates with the VTEP to manage the overlay network and ensure that traffic is correctly routed and encapsulated across the network infrastructure1.

Role of other NSX Components: While the NSX Edge provides routing services and the NSX Manager is the centralized management component, it is the NSX Controller that directly manages the state of the virtual network and communicates with the VTEPs1.


Question No. 4

A customer site has a VM in the VxBlock dedicated to a multicast application. The network monitoring team observes heavy network utilization each time the video streaming is requested.

What should be enabled to address this issue?

Show Answer Hide Answer
Correct Answer: C

Identify the Issue: Heavy network utilization during video streaming indicates that multicast traffic is not being efficiently managed1.

Understand Multicast Traffic: Multicast applications use a single stream of data to deliver content to multiple recipients, which can cause network congestion if not handled properly1.

Recognize IGMP's Role: Internet Group Management Protocol (IGMP) is used to manage multicast group memberships and is essential for optimizing multicast traffic on a network1.

Implement IGMP: Enabling IGMP allows the network to efficiently distribute multicast traffic only to hosts that have explicitly requested it, reducing unnecessary network load1.


Question No. 5

Who is an optional resource during an RCM upgrade escalation?

Show Answer Hide Answer
Correct Answer: D

During an RCM (Release Certification Matrix) upgrade escalation, the Delivery Manager is an optional resource. While not always required, the Delivery Manager can be involved to provide additional oversight and coordination if needed.
