+Useful with dynamic NAT in the event you run out of dynamic addresses to translate to. Clearing translations will free up slots if the clearout timer isn't quick enough.

+===== Chapter Questions =====
+==== One ====
+Examine the following show command output on a router configured for dynamic NAT:
+<code>
+-- Inside Source
+access-list 1 pool fred refcount 2288
+ pool fred: netmask 255.255.255.240
+    start 200.1.1.1 end 200.1.1.7
+    type generic, total addresses 7, allocated 7 (100%), misses 965
+Users are complaining about not being able to reach the Internet. Which of the following is the most likely cause?
+</code>
+The NAT pool does not have enough entries to satisfy all requests.
+The problem is not related to NAT, based on the information in the command output.
+The command output does not supply enough information to identify the problem.
+Standard ACL 1 cannot be used; an extended ACL must be used.
+You answered this question correctly. ×
+Explanation:
+The last line mentions that the pool has seven addresses, with all seven allocated, with the misses counter close to 1000 - meaning that close to 1000 new flows were rejected because of insufficient space in the NAT pool.
