Which two configuration options can only be enabled on distributed switches?

Port Mirroring and NetFlow are indeed features that can only be enabled on distributed switches in a VMware environment.

Port Mirroring is a network management feature that allows traffic to be duplicated and sent to another port for monitoring or analysis purposes. Distributed switches provide a centralized management point that simplifies such configurations across multiple hosts, making it easier to set up and manage port mirroring for all virtual machines connected to the distributed switch.

NetFlow is another feature exclusive to distributed switches that provides detailed insights into network traffic patterns. By monitoring and analyzing traffic flows, administrators can gain visibility into bandwidth consumption, application performance, and user behavior. Similar to port mirroring, the centralized architecture of a distributed switch allows for efficient configuration and reporting of NetFlow data.

In contrast, VLAN IDs, NIC Teaming, and Load Balancing can be configured on both standard and distributed switches. This is because these features are fundamental networking functions that do not necessitate the centralized management capabilities that distributed switches provide. While they benefit from the scalability and management features of distributed switches, they are not exclusive to them. Thus, the correct recognition of Port Mirroring alongside NetFlow as features exclusive to distributed switches highlights their advanced capabilities in comprehensive network management.
