Refer to the exhibit. Router R14 is being configured. Which configuration should be used to create a host route to PC 10?

  • A ip route 10.80.65.10 255.255.255.254 10.80.65.1
  • B ip route 10.80.65.10 255.255.255.255 10.73.65.66
  • C ip route 10.73.65.66 0.0.0.255 10.80.65.10
  • D ip route 10.73.65.66 255.0.0.0 10.80.65.10
Explanation

A host route identifies one specific destination IP address, so the static route must use the 255.255.255.255 mask. PC 10 has address 10.80.65.10, and from R14 the correct next hop toward that host is R86 at 10.73.65.66 across the 10.73.65.64/30 link. Therefore the correct static route is ip route 10.80.65.10 255.255.255.255 10.73.65.66.
