The commandvmkping ++netstack=geneve -d -s 1572 <destination IP address>is used to check the VMware kernel ports for tunnel end point communication. This command uses the geneve netstack, which is the default netstack for NSX-T. The-doption sets the DF (Don't Fragment) bit in the IP header, which prevents the packet from being fragmented by intermediate routers. The-s 1572option sets the packet size to 1572 bytes, which is the maximum payload size for a geneve encapsulated packet with an MTU of 1600 bytes. The<destination IP address>is the IP address of the remote ESXi host or VM.Reference: : VMware NSX-T Data Center Installation Guide, page 19. : VMware Knowledge Base: Testing MTU with the vmkping command (1003728). : VMware NSX-T Data Center Administration Guide, page 102.

ECMP (Equal Cost Multi-Path) is a routing protocol that increases the north and south communication bandwidth by adding an uplink to the tier-0 logical router and configure it for each Edge node in an NSX Edge cluster2.The ECMP routing paths are used to load balance traffic and provide fault tolerance for failed paths2.The tier-0 logical router must be in active-active mode for ECMP to be available2.A maximum of eight ECMP paths are supported2. Configuring ECMP on the tier-0 gateway can address low throughput and congestion by distributing the traffic among multiple paths and avoiding bottlenecks.

Deploying Large size Edge node/s can also address low throughput and congestion by providing more resources (memory, CPU, disk) for the Edge node to handle the network traffic.The NSX Edge VM system requirements vary depending on the appliance size, which affects the bandwidth, NAT/firewall, load balancer, and VPN capabilities of the Edge node1.A Large size Edge node has 32 GB memory, 8 vCPU, 200 GB disk space, and can support 2-10 Gbps bandwidth, L2-L4 features, and L7 load balancer1.An Extra Large size Edge node has 64 GB memory, 16 vCPU, 200 GB disk space, and can support more than 10 Gbps bandwidth, L2-L4 features, L7 load balancer, and VPN1.Deploying a larger size Edge node can improve the performance and capacity of the tier-0 gateway.Reference:2: Understanding ECMP Routing - VMware Docs(https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-443B6B0D-F179-429E-83F3-E136038332E0.html)1: NSX Edge VM System Requirements - VMware Docs(https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/installation/GUID-22F87CA8-01A9-4F2E-B7DB-9350CA60EA4E.html)

The four types of role-based access control (RBAC) permissions areRead,None,Full access, andExecute1. Read permission allows the user to view the configuration and status of the system. None permission denies any access to the system. Full access permission grants all permissions including Create, Read, Update, and Delete (CRUD).Execute permission includes Read and Update permissions1. Auditor, Enterprise Admin, and Network Admin are not types of permissions, but types of roles that have different sets of permissions.Reference:NSX Features

There are four types of permissions. Included in the list are the abbreviations for the permissions that are used in theRoles and PermissionsandRoles and Permissions for Manager Modetables.

Full access (FA) - All permissions including Create, Read, Update, and Delete

Execute (E) - Includes Read and Update

Read (R)

None

NSX-T Data Centerhas the following built-in roles. Role names in the UI can be different in the API. InNSX-T Data Center, if you have permission, you can clone an existing role, add a new role, edit newly created roles, or delete newly created roles.

A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once.A node profile can include settings such as NTP server, DNS server, syslog server, and so on1.By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient.Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.

According to the VMware NSX Documentation1, NSX-T Data Center supports the following types of DHCP configuration on a segment:

Local DHCP server: This option creates a local DHCP server that has an IP address on the segment and provides dynamic IP assignment service only to the VMs that are attached to the segment.

Gateway DHCP server: This option is attached to a tier-0 or tier-1 gateway and provides DHCP service to the networks (overlay segments) that are directly connected to the gateway and configured to use a gateway DHCP server.

DHCP Relay: This option relays the DHCP client requests to the external DHCP servers that can be in any subnet, outside the SDDC, or in the physical network.
