•Statement A: "The trace successfully reached the www.cisco.com server. " This is true as indicated by the "Trace complete" message at the end, showing that the trace has reached its destination.

•Statement C: "The IPv6 address associated with the www.cisco.com server is 2600:1408:c400:38d::b33. " This is true because the final hop in the trace, which is the destination, has this IPv6 address.

•Statement B: "The trace failed after the fourth hop." This is incorrect as the trace continues beyond the fourth hop, despite some intermediate timeouts.

•Statement D: "The routers at hops 5 and 6 are offline." This is not necessarily true. The routers might be configured to not respond to traceroute requests.

•Statement E: "The device sending the trace has IPv6 address 2600:1408:c400:38d::b33." This is incorrect; this address belongs to the destination server, not the sender.
