1- For [ Critical voice ] wording. Is it a proctor question to ask if he it
requires matching precedence 5 in the ACL used to match the voice traffic?
2- Again is it a proctor question if I like to confirm if [ maximum reserved
bandwidth 100 ] is required or not?
4- Regarding the class-default as the question says remaining bandwidth will
go for the default class. This is the default behavior any way so I think no
extra configuration is required for it.
