A VxBlock 1000 UCS domain is being managed via Fabric Interconnect (FI) A as the cluster lead. The expansion team adds two new B-series servers to the domain. When attempting to vMotion from the existing blades to one of the new blades, the power to Fabric Interconnect A is disconnected.
What is the expected result?
- A . vMotion completes successfully, but access to the vCenter will be lost
- B . vMotion fails, but is automatically retried once the Fl comes back online
- C . vMotion fails because the Fl managing the session is powered off
- D . vMotion completes successfully despite the FI power failure
C
Explanation:
Review VxBlock 1000 UCS Domain Management: The UCS domain is managed via Fabric Interconnect A, which acts as the cluster lead and is critical for operations1.
Understand vMotion Process: vMotion is a VMware feature that allows for the live migration of virtual machines from one host to another without downtime1.
Identify Impact of FI A Power Disconnection: If the power to Fabric Interconnect A is disconnected during a vMotion process, the vMotion session being managed by FI A will fail because it loses its management connection1.
Recognize Automatic Retry Mechanism: Although vMotion fails when FI A is powered off, it is typically designed to retry the operation once the managing FI comes back online1.
Reference Official Dell Documentation: The Official Dell VxBlock Deploy Achievement document would confirm that the expected result of such a scenario is the failure of the vMotion process due to the power disconnection of the managing Fabric Interconnect1.

What order of steps is taken when using an NSX edge service gateway with proxy mode load balancing?
Explanation:
The order of steps taken when using an NSX edge service gateway with proxy mode load balancing is as follows:
Client sends traffic to virtual IP address exposed by the load balancer.
Load balancer performs address translation and sends traffic to server IP.
Server replies by sending the traffic to the load balancer.
Load balancer performs address translation and sends the traffic to client IP.
The process begins with a client initiating communication by sending traffic to a virtual IP address, which is managed by the NSX edge service gateway functioning as a load balancer.
Upon receiving the traffic, the load balancer translates this virtual IP address into one of the actual server IPs that it manages, effectively directing the client’s request to an appropriate server in its pool.
The selected server processes this request and responds back, sending its reply to the load balancer rather than directly back to the client.
Finally, once receiving this response from the server, the load balancer translates it from its own internal server IP back into what appears as a response from the original virtual IP address and forwards this response on to complete communication loop back at the client’s end. .
In an existing VxBlock 1000 system, the compute servers are running VMware ESXi hypervisors. A compute expansion is being planned that includes servers that are being repurposed from another VxBlock system.
What licensing is required for the expansion?
- A . Cisco MDS Port licenses
- B . VMware vSphere ESXi and Dell EMC PowerPath licenses
- C . Cisco UCS Fabric Interconnect Port license
- D . VMware vSphere ESXi and Cisco 1000v license
D
Explanation:
When planning a compute expansion in an existing VxBlock 1000 system with servers repurposed from another VxBlock system, the required licensing includes VMware vSphere ESXi and Cisco 1000v licenses. These licenses ensure that the new compute resources are properly integrated and managed within the existing VxBlock environment.

What service is provided by a VMKernel NIC?
- A . vMotion
- B . vCenter management
- C . VDS management
- D . System control
A
Explanation:
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.
What is the responsibility of the Implementation Specialist during the deployment cycle?
- A . Physically uncrate VxBlock racks and acclimatize
- B . Perform inter-rack cabling
- C . Execute test plan and validation
- D . Create the Site and Logical Configuration Surveys
C
Explanation:
Locate the validation procedures and support documentation: The Implementation Specialist must locate the necessary validation procedures and support documentation that are essential for the deployment of the VxBlock Systems1.
Connect the VxBlock System to the customer network: After locating the documentation, the specialist is responsible for connecting the VxBlock System to the customer’s network1. Validate a VxBlock 1000 installation using the LCS and Test Plan: The specialist must validate the VxBlock 1000 installation using the Lifecycle System (LCS) and the Test Plan to ensure that the system is correctly implemented and functioning as intended1.
Describe how to perform knowledge transfers: Part of the specialist’s role is to describe the process of knowledge transfer, ensuring that the customer’s staff is adequately trained and informed about the system1.
What is a key benefit VxLAN?
- 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.
B
Explanation:
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.
