Which old RouterOS feature is deprecated and associated with switch grouping?

• A. Master Port
• B. Switch Chip
• C. ARP
• D. DHCP Client

Answer: (A)

Grouping multiple ports to behave as a single switch path in RouterOS used to be done with a Master Port. This approach is deprecated because modern RouterOS relies on the built-in switch chip and dedicated switch interfaces to manage port groups, VLANs, and bridging. In current configurations, you set up a switch using the switch chip’s features rather than assigning a master/slave relationship between ports. The other options don’t describe how port groups are deprecated for switching: ARP is about mapping IPs to MACs, DHCP Client handles obtaining IP settings from a server, and the Switch Chip refers to the hardware that performs switching today rather than a deprecated configuration method.
