You analyze Lytic traffic modeling for a customer’s network. The network includes a main office, a data center, and five branch offices. Lync servers are consolidated in the data center. The main office and the data center are connected to a Multiprotocol Label Switching (MPLS) network. The branch offices are connected to the main office with virtual private network (VPN) links. The model uses all Lync modalities for all users. The network topology diagram is shown in the exhibit. (Click the Exhibit button.)
The model indicates that the main office exceeds the bandwidth available for Lync over the MPLS link by 10 percent. The utilization of VPN links available for Lync traffic is at almost 100 percent.
You need to recommend a change to optimize Lync traffic through the main office MPLS link.
What should you recommend?
A. Move the Lync pool to the main office.
B. Move the Lync pool to a branch office.
C. Deploy a Survivable Branch Appliance (SBA) at all branches.
D. Deploy a Survivable Branch Appliance (SBA) at the main office.
