Question

Which prompt is used to configure parameters for the Ethernet ports of an industrial switch?

Options

ASwitch(config-if)#
BSwitch(config-if-ind)#
CSwitch(config-line)#
DSwitch(config-ind)#
ESwitch(config-vlan)#

Explanation

Switch(config-if)# is the interface configuration mode prompt, entered via interface <type> <number> from global config - this is where you set parameters like speed, duplex, switchport mode, and shutdown for any switch port, including Ethernet ports on industrial switches. Option B (config-if-ind) and D (config-ind) are fabricated prompts that don't exist in IOS or industrial switch CLIs. Option C (config-line)#) is real but configures console/VTY/AUX lines for terminal access, not Ethernet ports. Option E (config-vlan)#) is also real but is used to configure VLAN database settings, not individual port parameters.

Memory tip: Think "if" = "interface" - config-if is always where you touch physical or logical ports.
