The 'Switch Visualization' feature in the NSX UI provides a visual representation of the network, showing the mapping between virtual NICs and the host's physical adapters. This visualization helps administrators troubleshoot connectivity issues by clearly displaying the connections and configurations of the network switches and the corresponding adapters on the hosts.

To enable NSX Edge Services for a VM on a VLAN-backed logical switch, a service interface needs to be configured on a Tier-0 Gateway. The service interface is designed specifically to support services for VLAN-based networks. It connects the Tier-0 Gateway with VLAN-backed logical switches, facilitating the necessary networking functions such as routing, firewall, NAT, and VPNs that are essential for the deployment and operation of such services.

In a Single Tier topology, there is no Tier-1 gateway. Therefore, the interfaces related to Tier-1 (options D and E) are not applicable. Ingress traffic on the Edge node in a Single Tier topology involves the Tier-0 Uplink interface, which connects the edge node to the physical network, and the Downlink Interface for the Tier-0 Distributed Router (DR), which connects to the logical network. Thus, the correct options are the Tier-0 Uplink interface and the Downlink Interface for the Tier-0 DR.

The three security features dependent on the NSX Application Platform are NSX Intelligence, NSX Network Detection and Response, and NSX Malware Prevention. NSX Intelligence provides advanced analytics and visibility, enabling security insights. NSX Network Detection and Response offers capabilities for detecting and responding to network-based threats. NSX Malware Prevention provides mechanisms to detect and prevent malware within network traffic.

Profiles exist only on Tier-1 Gateway firewall configurations and not on Tier-0. This is because context profiles, a specific type of profile used for advanced rules and filtering, are only available on Tier-1 gateways.
