Question 3 - 2V0-41.23 discussion

Unicast is the traffic type that an NSX administrator should use for validating connectivity between App and DB virtual machines that reside on different segments.According to the VMware documentation1, unicast traffic is the traffic type that is used to send a packet from one source to one destination.Unicast traffic is the most common type of traffic in a network, and it is used for applications such as web browsing, email, file transfer, and so on2.To perform a traceflow with unicast traffic, the NSX administrator needs to specify the source and destination IP addresses, and optionally the protocol and related parameters1.The traceflow will show the path of the packet across the network and any observations or errors along the way3. The other options are incorrect because they are not suitable for validating connectivity between two specific virtual machines.Multicast traffic is the traffic type that is used to send a packet from one source to multiple destinations simultaneously2.Multicast traffic is used for applications such as video streaming, online gaming, and group communication4.To perform a traceflow with multicast traffic, the NSX administrator needs to specify the source IP address and the destination multicast IP address1.Broadcast traffic is the traffic type that is used to send a packet from one source to all devices on the same subnet2. Broadcast traffic is used for applications such as ARP, DHCP, and network discovery.To perform a traceflow with broadcast traffic, the NSX administrator needs to specify the source IP address and the destination MAC address as FF:FF:FF:FF:FF:FF1. Anycast traffic is not a valid option, as it is not supported by NSX Traceflow. Anycast traffic is a traffic type that is used to send a packet from one source to the nearest or best destination among a group of devices that share the same IP address. Anycast traffic is used for applications such as DNS, CDN, and load balancing.
