NEW QUESTION # 26
What is a key benefit VxLAN?
- A. It reduces implementation cost of multiple VxBlock systems sharing data centers.
- B. It enables inter-VM communications among data center servers in different Layer 2 subnets.
- C. It enables vMotion over Layer 3 subnets across geographic locations.
- D. It can be configured in the hypervisor to support an NSX implementation.
Answer: C
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.
NEW QUESTION # 27
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 isrequested.
What should be enabled to address this issue?
- A. VTP
- B. IGMP
- C. LACP
- D. vPC
Answer: B
Explanation:
* 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.
NEW QUESTION # 28
Which required NSX component abstracts the physical network and provides access-level switching in the hypervisor?
- A. Edge Services Gateway
- B. Distributed Logical Router
- C. vSphere Distributed Switch
- D. vSphere Standard Switch
Answer: B
Explanation:
The Distributed Logical Router (DLR) is the NSX component that abstracts the physical network and provides access-level switching in the hypervisor. The DLR enables routing between different virtual networks and operates at the hypervisor level, providing high-performance distributed routing capabilities.

NEW QUESTION # 34
A customer is planning to integrate a VxBlock to a new Cisco ACI fabric. What major physical connectivity change is needed if the customer intends to convert their existing VxBlock Nexus 9396PX switches to ACI mode?
- A. Nexus 9396PX switch cannot be integrated directly to ACI fabric.
- B. Connect the Nexus 9396PX switch to spine Nexus 9500 switches. Remove other connections between the Nexus 9396PX switches.
- C. Connect the switch directly to the APIC to download the ACI software. Then connect the existing Nexus
9396PX switches to a spine Nexus 93180YC switch. - D. Remove the dual peer link connection but keep the peer link connection for ACI fabric heartbeat traffic exchange.
Answer: C
Explanation:
To convert existing VxBlock Nexus 9396PX switches to ACI mode, a major physical connectivity change involves connecting the switch directly to the APIC (Application Policy Infrastructure Controller) to download the ACI software. Afterward, the existing Nexus 9396PX switches should be connected to a spine Nexus 93180YC switch as part of the ACI fabric setup.

NEW QUESTION # 35
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 fails, but is automatically retried once the Fl comes back online
- B. vMotion completes successfully, but access to the vCenter will be lost
- C. vMotion completes successfully despite the FI power failure
- D. vMotion fails because the Fl managing the session is powered off
Answer: D
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.

NEW QUESTION # 38 
Refer to the exhibit.
A cable with the following label was connected to the wrong equipment type:
* M91A-01:01 U61A-01:09
Based on the exhibit, what is the target equipment type?
- A. Nexus 9xxx, Slot A, Port1
- B. UCS 5108 Chasses A, Slot 1, Port 9
- C. UCS 6xxx FI, Uplink A, Slot 1, port 9
- D. MDS 9xxx, Slot 1, Port 1
Answer: D
Explanation:
The label on the cable indicates two parts: "M91A-01:01" and "U61A-01:09". The first part of the label
"M91A" refers to a specific type of equipment as per the exhibit. According to the exhibit, "M9" corresponds to "MDS 9xxx", which is a Cisco Multilayer Director Switch. The second part of the label, "U61A", does not directly match any category in the provided list; however, it seems to be an internal reference that could be related to user-specific configurations or locations.
Since we are looking for the target equipment type and not where it was mistakenly connected, we focus on the first part of the cable label. The numbers following "M91A" indicate slot and port information. Therefore, based on this labeling system and referring to the exhibit provided, which lists various EMC and Cisco equipment types along with their corresponding codes (like AP for APIC Appliance or CN for Cust. Network), we can deduce that "M91A" stands for "MDS 9xxx". The subsequent numbers "-01:01" suggest Slot 1, Port 1.

NEW QUESTION # 41
What is needed to provide network isolation between vSwitch port groups?
- A. Separate VLAN IDs
- B. Uplink port
- C. VMKernel port
- D. Shared VLAN ID
Answer: A
Explanation:
* Understand the role of VLANs: VLANs (Virtual Local Area Networks) are used to segment network traffic.They provide isolation between network segments at the data link layer (Layer 2) of the OSI model1.
* Identify the need for isolation: vSwitch port groups are used to segregate network traffic for different virtual machines or services.To ensure that each port group's traffic is isolated from the others, separate VLAN IDs are assigned1.
* Assign unique VLAN IDs: Each vSwitch port group should be assigned a unique VLAN ID to maintain network isolation.This prevents traffic from one port group from being accessible to another1.
* Configure the physical switch ports: The physical switch ports that the vSwitch is connected to must be configured to recognize the VLAN IDs used by the vSwitch port groups1.
* Validate the configuration: After configuring VLAN IDs, it's important to validate the configuration to ensure that the network isolation is functioning as intended1.
NEW QUESTION # 42
