I got the RHCE for RHEL 6 a few years ago and remember it being full of useless guff, such as configuring SAMBA users as well as users for other services, as well as iSCSI, etc. that you mention, none of which I've ever used (so, of course, have forgotten - it's hard to commit such rubbish to memory!).
And, while I've studied for the RHEL 7 RHCE haven't taken the exam yet, because it's expensive and full of much the same useless stuff.
It's probably good to learn a lot of the other, more useful stuff, just for your own knowledge, but I really don't think it's worth the effort, time or money to do all that's necessary for the exam (unless someone else is paying for it).
Probably looks good on the CV, but that's about it, IMO.

dspam_clean
dspam_clean(1) DSPAM dspam_clean(1)
NAME
dspam_clean - perform periodic maintenance of metadata
SYNOPSIS
dspam_clean [--profile=PROFILE] [-s[signature_life]] [-p[probability_life]] [-u[sl,hcl,shl,ihl]] [user1 user2 ... userN]
DESCRIPTION
dspam_clean is used to perform periodic housecleaning on DSPAM's metadata dictionary by deleting old or useless data.
OPTIONS
--profile=PROFILE
Specify a storage profile from dspam.conf. The storage profile selected will be used for all database connectivity. See dspam.conf
for more information.
-s Performs stale signature purging. If a value is specified, the default value of 14 days will be overridden. Specifying an age of 0
will delete all signatures from the user(s) processed.
-p Deletes all tokens from the target user(s) database whose probability is between 0.35 and 0.65 (fairly neutral, useless data). If a
value is specified, the default life of 30 days will be overridden. It's a good idea to use this flag once with a life of 0 days for
users after a significant amount of corpus training.
-u Deletes all unused tokens from a user's dataset. Four different life values are used:
sl Stale tokens which have not been used for a long period of time
hcl Tokens with a total hit count below 5 (which will be assigned a hapaxial value by DSPAM)
shl Tokens witha single spam hit
ihl Tokens with a single innocent hit
Ages may be overridden by specifying a format string, such as -u30,15,10,10 where each number represents the respective life. Speci-
fying a life of zero will delete all unused tokens in the category.
user1 user2 ... userN
Specify the username(s) to perform the selected maintenance operations on. If no username is specified, all users are processed.
EXIT VALUE
0 Operation was successful.
other Operation resulted in an error.
