FTP transfers occur.
Mr. Drew hands you the diagram shown in Figure 16-3. The exiting data network includes
35 sites with approximately 30 people at each site. The network is Multiprotocol Label
Switching (MPLS) WAN, with approximately 200 people at the headquarters. The WAN
links range from 384-kbps circuits to T1 speeds. Remote-site applications include statisti-
cal files and graphical-site diagrams that are transferred using FTP from remote sites to the
headquarters.

Mr. Drew wants a UC solution that manages the servers at headquarters but still provides
redundancy or failover at the remote site. He mentions that he is concerned that the FTP
traffic might impact the VoIP traffic. He wants to choose a site to implement a test before
implementing UC at all sites.
