• Question 99:

  Refer to the exhibit.

  

  For Company XYZ Bangkok is using ECMP to reach the 172 20 2 0/24 network The company wants a design that would allow them to forward traffic from 172 16 2 0/24 toward 172 20 2 0/24 via the Singapore router as the preferred route The rest of the traffic should continue to use ECMP.

  Which technology fulfills this design requirement?

  B. route summarization
  C. unequal-cost load balancing using variance
  D. LFA
  A. policy-based routing

• Question 100:
