Answer / guest
Answer: A
Route summarization DECREASES the size of the routing table
by combining multiple routing table entries into single
routing entry. The complexity of the network is increased
because you have to deal with contiguous addressing, parts
of the summary becoming disjoint, if more specific routes
leak out on another path the longest subnet match will drive
traffic there.
