Refer to the exhibit. The network administrator must configure Cape Town to reach Dubai through Tokyo according to the speeds supplied by the service provider. Cape Town is instead reaching Dubai directly and therefore does not meet the requirement. Which configuration resolves the issue?

  • A CapeTown -router eigrp 100variance 2
  • B CapeTown -interface E 0/0bandwidth 5000interface E 0/1bandwidth 10000
  • C CapeTown -interface E 0/0bandwidth 5000interface E 0/1bandwidth 10000Dubai -interface E 0/0bandwidth 50000interface E 0/1bandwidth 5000Tokyo -interface E 0/0bandwidth 50000interface E 0/1bandwidth 10000
  • D Dubai -router eigrp 100variance 2
Explanation

EIGRP selects the route with the lowest composite metric, which by default includes the minimum configured bandwidth along the path and cumulative delay. Configuring Cape Town’s direct interface as 5 Mbps and its Tokyo-facing interface as 10 Mbps makes the route through Tokyo preferable. The EIGRP autonomous system shown is 222, so commands under EIGRP 100 do not affect the routing process.
