正解:D
To monitor ingress traffic from SW1 and SW2 port-channel interfaces from SW3, the engineer must implement a configuration that specifies the source interfaces for monitoring and the destination interface where the monitored traffic will be sent. The correct configuration is found in Option D, which includes the commands to create a monitor session, specify the source interfaces as port-channel 1 and port-channel 2 with the 'rx' option to indicate ingress traffic, and set the destination interface to Ethernet 1/4 where the traffic can be analyzed. This setup uses a Switched Port Analyzer (SPAN) or Remote SPAN (RSPAN) to capture and forward the traffic for monitoring purposes.
