vty, con, and aux configuration

All,

Most lab scenarios give the following instructions with regard to virtual
terminal access methods:

"Do not change the console aux, or vty access methods unless otherwise
specified"

Given the above statement and the appropriate situation, would adding the
following statements be considered a violation?

0.
Default config:
line con 0
line aux 0
line vty 0 4

1.
ena pass cisco

line vty 0 4
 exec-timeout 0 0
 logging synchronous
 no login

2.
ena pass cisco

line vty 0 4
 exec-timeout 0 0
 logging synchronous
 login
 password cisco

3.
ena pass cisco

line vty 0 4
 exec-timeout 0 0
 privilege level 15
 logging synchronous
 no login

4.
Ena pass cisco
Username cisco password cisco

line vty 0 4
 exec-timeout 0 0
 logging synchronous
 login local

5. (dot1x with radius)
!
aaa new-model
aaa authentication login default none
aaa authentication dot1x default group radius
enable password cisco
!
line con 0
 exec-timeout 0 0
 logging synchronous
line vty 0 4
 exec-timeout 0 0
 password cisco
 logging synchronous

Last question, if you are not given any instruction with regard to the vty,
aux or con, would options 1 or 2 meet the "must be able to telnet to all
routers" requirement.

(Trying to confirm, everything I think I know. Excuse the idiocy!)

Thank in advance,
Al
