If you dont mind could you please explaine
Good network bandwidth means what will be the range of data transfer
what bandwidht can consider GOOD
And below what range can consider bad
its all depends on the organisation what they have and i would say below 100MB or so would consider slow.You can contact network guys to get more about the bandwitdth what your organisation have ?
What is the definition of a "well-connected network" in regards to a Primary site?
its straight forward.Primary site is used to manage clients which are well-connected means with Good network bandwidth but where as secondary sites are used to manage clients in low-bandwidth networks
