A. B. C. D.A
On MX Series devices, the interface type that connects the control and forwarding planes is the me0 interface.
The forwarding plane is responsible for forwarding traffic through the device, while the control plane is responsible for managing the device's operation, such as processing routing protocols, managing interfaces, and communicating with other devices.
The me0 interface, also known as the management Ethernet interface, is used for out-of-band management of the device and for communication between the control and forwarding planes. This interface is used for management traffic and does not participate in the forwarding of data traffic.
Option A fxp1 and Option B fxp0 are both used for remote management and are not used to connect the control and forwarding planes.
Option D ae1 is an aggregated Ethernet interface and is used for combining multiple Ethernet interfaces into a single logical interface. This interface is used for forwarding traffic, but it is not used to connect the control and forwarding planes.
Therefore, the correct answer is option C, me0.
