QoS has already been deployed and optimized, but it is no longer sufficient to ensure optimal network performance. Which two solutions should the architect use to improve network performance? (Choose two.)

B, D 4
Selected Answer: BD
As the question mentions that QoS has been implemented and optimized, I can assume A and C have already been done. So I prefer B & D to upgrade the link and add new uplinks

I have answers as A and C???
A, C 1
Selected Answer: AC
For me also A and C make sense.
B, D 1
Selected Answer: BD
I went for B and D straight away because the question says that 'QoS has already been... optimized' which rules out any more fiddling with QoS. Dropping noncritical network traffic (A) to me is far from optimal network performance
A, C 1
Selected Answer: AC
AC would love to say BD, throw more bandwidth at it, but that would make most questions on QOS pointless...
B, D 1
Selected Answer: BD
B and D are right.

Since we are talking about access and distribution switches, these are usually in close proximity and adding links should not be much of an issue. From that point, BD.
I completely see your point.....but maybe at the core level where adding more may be hard.
