Hope network's designed to be aware of best practice (4,3,5)
I believe the answer is:
know the ropes
'be aware of best practice' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'hope network's designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'hope'+'networks'='hopenetworks'
'hopenetworks' is an anagram of 'KNOW THE ROPES'.
'to' is the link.
Can you help me to learn more?
(Other definitions for know the ropes that I've seen before include "Understand normal procedures" , "Be familiar with procedure" , "Campanologists should" , "Be experienced" , "be up to speed" .)
