【正确答案】 D

【答案解析】 A选项中“C 222.29.159.8/29 is directly connected，FastEthernet2/5”处“FastEthemet2/5”错误，该位置应该填入具体的虚拟局域网号。B选项中“0 E1 222.29.87.0/24 [120/21]via 162.105.254.24，2d16h，Vlan2”处“[120/21]”错误，这里面O代表的是OSPF协议，其管理距离应该是110。C选项中“S 222.29.159.48/28[1/0]via Vlan908”处“via vlan908”错误，via后面应该是一个具体的IP地址。故选择D选项。
