A client has a large ESX environment that they backup using EMC NetWorker. Their virtual
machines are a mix of database and non-database servers. They currently perform
guest-based backups so that their database server backups are application consistent.
They have asked you to address some performance issues they have been encountering.
Specifically, network utilization is high during backups. They would like you to provide a
recommendation to reduce network traffic without adding additional cost while retaining
application consistency. What is a recommended solution that addresses the customer’s
issues?

A.
Provide additional bandwidth to the environment by replacing slower equipment
with faster equipment

B.
Provide additional bandwidth to the environment by installing additional network
equipment

C.
Switch the non-database servers to image-based backups and leave the database
servers as is

D.
