Examine the following show command output on a router configured for dynamic NAT:

— Inside Source
access-list 1 pool ccna
pool ccna: netmask 255.255.255.240
start 190.1.1.1 end 190.1.1.10
type generic, total addresses 10, allocated 10 (100%), misses 595

You are responsible to find out why users are not being able to reach the Internet.

(A) The cause is not related to dynamic NAT
(B) The command output does not provide any clue to identify the problem
(C) Dynamic NAT can't use Standard ACLs
(D) The NAT pool does not have enough entries to fulfill the user's requests

The NAT pool does not have enough entries to fulfill the user's requests is the correct answer. As you can see, the last line mentions that the pool has ten addresses, with all ten allocated, with the misses counter 595, meaning that 595 new flows were rejected because of insufficient space in the NAT pool.
