I believe, your solution 2 is wrong (it does what you were asked to do,
but it also limits traffic from all users to 3Mbps).
The solution from guide limits traffic from each user (port) to 3Mbps
rate, without any relation to summary rate (as in your solution).
For example, if some port receives traffic at 2Mbps and other also at
2Mbps, your solution will limit summary rate from 4Mbps to 3Mbps.
But proposed solution - won't.

Below are two scenario I ran into in my practice workbook. Please let
me know if my solution is correct and any reason its not thanks
Question states
VLAN B should allow no more than 2mb total throughput. Would my
solution still be correct? Where did they get the 250000 in Solution 1
and 375000 in Solution 2?
My solution
mls qos aggregate-policer AGG 2000000 1000000 exceed-action drop
!
policy-map POLICE-AGG
class class-default
police aggregate AGG
interface FastEthernet0/1
switchport access vlan 12
service-policy input POLICE-AGG
!
interface FastEthernet0/2
switchport access vlan 12
service-policy input POLICE-AGG
Solution guide
mls qos aggregate-policer VLANB 2000000 250000 exceed-action drop
!
class-map match-all B
match vlan 12
match class-map class-default
!
!
policy-map MyQoS
class B
police aggregate VLANB
interface FastEthernet0/1
switchport access vlan 12
service-policy input MYQOS!
interface FastEthernet0/2
switchport access vlan 12
service-policy input MYQOS
Question 2 : Vlan D should make sure that any speaker will not flood the
LAN with more than 3MB of traffic at a time
My solution
mls qos aggregate-policer VLAND 3000000 1000000 exceed-action drop
policy-map AGG
class class-default
police aggregate VLAND
Service policy applied inbound on ports in the VLAN
Solution guide
policy-map VLAND
class class-default
police 3000000 375000 exceed-action drop
