This may be as significant with the one-day exam, but FWIW I did not use
aliases in the lab nor did I use them on my practice lab.
My reasoning is that in the old-style two day lab your troubleshooting
is likely to be on a different network. If you look at the alias lists
suggested here you'll see that they're primarily show and debug commands.
If you become accustomed to your favorite alias lists, you'll come to
rely on them. Getting hit with a new network and limited time means
going through the hassle of entering your alias lists again on all of
the routers or doing without them.
Practicing using unaliased commands will improve your speed in typing
them. I got to the point that I could type "sh ip bgp nei" about as
quickly and effortlessly as typing my name, and I'm not a particularly
good or fast typist.
I sgree with the idea of setting helpful global configuration commands
early in the setup stage.
no ip domain-lookup
ip tcp synwait-time 5
ip subnet-zero
line con 0
exec-timeout 0 0
are good examples.
With the one-day setup, entering aliases may be of some benefit but
IMHO it's one more thing to stress over and of little value. Practicing
without them doubtless helped my speed in troubleshooting, and is useful
in real life when working on customer networks.
