The correct answer is D. resequencing.
Named access-lists are used to control traffic flows in and out of Cisco network devices. They are similar to standard and extended access-lists, but are named with a user-defined name rather than a number.
To change the order of entries in a named access-list, you can use the "resequencing" feature. This feature allows you to change the sequence numbers assigned to each entry in the access-list.
By default, entries in a named access-list are assigned sequence numbers in increments of 10. For example, if you add a new entry to an access-list that already has 3 entries, the new entry will be assigned sequence number 40 (10 more than the last entry).
To change the order of entries, you can use the "resequence" command with the "ip access-list extended" configuration mode. The syntax is as follows:
Router(config)#ip access-list extended ACL_NAME Router(config-ext-nacl)#resequence [START] [INCREMENT]
The START parameter specifies the starting sequence number for the access-list entries, and the INCREMENT parameter specifies the increment value for the sequence numbers.
For example, to resequence the entries in an access-list named "CUSTOMER_ACL" starting at sequence number 10 and incrementing by 5, you would use the following command:
Router(config)#ip access-list extended CUSTOMER_ACL Router(config-ext-nacl)#resequence 10 5
This would change the sequence numbers for the access-list entries to 10, 15, 20, 25, etc. This can be useful if you want to insert new entries into the access-list at a specific location, or if you want to reorder the entries for better readability or efficiency.
Therefore, the correct answer is D. resequencing.
