The old favourite - to map or not to map....

Hi

On pages 92 and 93 of CCIE Routing and Switching LAB Practice labs by Cisco
it gives a solution which uses "no frame relay inverse-arp" after asking the
question "ensure that DLCIs 110 and 104 between R1 and R6 are not
used. The "no fr inverse-arp" is configed on a main interface and a
sub-interface used for p2p connection (with the IP going on the
sub-interface).

Now I know that "no frame relay inverse-arp" on an interface without an IP
address does nothing (coz I have read the mails from Brian Dennis ;-) But
then why does the Cisco Press book award one point for this??? In a lab
scenario I would not config the command where an IP address does not exist
as I would view this as overconfiguration. Am I missing something subtle
here?
