OPTION D IS CORRECT
In network routing, the control plane is the part of the router architecture that is concerned with drawing the network topology, or the information in a (possibly augmented) routing table that defines what to do with incoming packets.
Kindly revert for any queries
Thanks.

This chapter ("data plane") is all about forwarding packets at a router. Check all the statements that apply to Forwarding: Forwarding tables are computed by the control plane, in software. Forwarding tables are typically stored at every input port of a router. Forwarding tables are typically stored at every output port of a router. Forwarding tables are stored in the switching fabric. Destination-based forwarding means that we use the destination address of an IP datagram, to look...
(5 marks) A 2900-byte datagram arrives at a router link that has a maximum transmission unit of 600 bytes. The original datagram has an identification number of 1337. How many fragments will be generated and what are the relevant fields in the IP datagram(s) that will be related to fragmentation. This question is probably best addressed with a diagram of the datagrams showing the relevant fields. 3. 4. (2 marks) Does a router inside an AS (non-edge router) need to...
