Which of the following statements about IP route summarization is FALSE?

Route summarization (a.k.a. supernetting) is the process of combining multiple contiguous subnets

into a single summarized route, which:

Reduces routing table entries

Enhances scalability and efficiency

Minimizes instability by localizing route changes

Option A is false because it describes subnetting, not summarization. Summarization works in the

opposite direction – combining smaller routes into a larger one.
