An administrator is attempting to confirm the successful transmission between an internal VM to an external destination.
An ICMP request packet is being sent from Sa-transit-web-01 to the Student Desktop in the diagram.
Drag and Drop the commands output into their appropriate originating NSX object.

Correct Answer:

Explanation:

In a modernVCF 9.0environment using theVirtual Private Cloud (VPC)model, North-South traffic follows a specific hierarchical path. When a VM, such asSa-transit-web-01, initiates an ICMP request to an external destination (the Student Desktop), the packet must traverse the VPC's internal routing before exiting to the physical network.
The first hop is theVPC Tier-1 Gateway. This gateway manages the localized subnets within the VPC. In this architecture, the VPC Tier-1 is typically configured with a default route ($0.0.0.0/0$) pointing to the Transit Gateway (TGW). The gateway address 100.64.0.0 represents the provider-side interface of the Router Link connecting the VPC to the Transit Gateway. Thus, the command output showing the default route to 100.64.0.0 belongs to the VPC Gateway.
The second hop is theDistributed Transit Gateway DR. The Transit Gateway acts as the aggregation point for multiple VPCs and provides the bridge to the physical datacenter fabric. The command output for this object shows a default route with a gateway of 0.0.0.0, indicating it is directly peered or using a specific unnumbered interface to reach the physical router. Additionally, it identifies the specific physical router IP (172.20.13.254/32) as a known local next-hop, which is a common characteristic of the Transit Gateway's forwarding table when performing North-South transitions.
Finally, theTransport Node (ESXi Host)is where the physical packet capture occurs. As the packet exits the virtual environment, it is placed on a physical uplink (vmnic1). The packet capture output confirms the transformation of the traffic: it shows the source IP of the VM (or its translated NAT address 172.20.13.65) reaching out to the destination 172.20.10.10. The inclusion of ipproto 0x01 (ICMP) and the specific MAC addresses confirms that the packet has successfully traversed the NSX overlay and is now a standard Ethernet frame on the physical wire.

An administrator is configuring NSX resource sharing to allow shared access to multiple resources in the default space.
By default, which user role owns the shared resources for the default space?

• A.Security Admin
• B.Project Admin
• C.Network Admin
• D.Enterprise Admin

When using a DHCP Relay on a segment, which design restriction must be considered?

• A.DHCP settings, DHCP options, and static bindings can be configured on the segment.
• B.DHCP client requests cannot be relayed to the external DHCP servers.
• C.DHCP Relay service is available to all the other segments in the network.
• D.DHCP settings, DHCP options, and static bindings cannot be configured on the segment.

An administrator is troubleshooting intermittent connectivity failures between two workloads connected to NSX VLAN segments using Traceflow. In-band Network Telemetry (INT) has been enabled in the NSX Global Configuration. How does Traceflow identify issues in a VLAN network?

• A.Compares intended network state in the control plane with Tunnel End Point (TEP) keepalives in the data plane.
• B.Injects synthetic traffic into the data plane and observes the results in the control plane.
• C.Traceflow cannot be enabled to analyze VLAN network segments in NSX.
• D.Injects ICMP traffic into the data plane and observes the results in the control plane.

In an NSX environment, an administrator is observing low throughput and intermittent congestion between the Tier-0 Gateway and the upstream physical routers. The environment was designed for high availability and load balancing, using two Edge Nodes deployed in Active/Active mode. The administrator enables ECMP on the Tier-0 gateway, but the issues persist. Which action would address low throughput and congestion?

• A.Deploy additional Edge nodes.
• B.Disable NAT on the Tier-0 gateway.
• C.Add an additional vNIC to the NSX Edge node.
• D.Convert Tier-1 gateways to be edgeless.
