the network is a high-speed data center where there is ample bandwidth to support the addition of VoIP
traffic. ?The remote offices that the data center services are all connected via Frame Relay (FR). After
setting up several NetIQ Chariot VoIP endpoints at remote - office locations, you identify the following
issues: ?Excessive delays during peak hours, as much as 200 milliseconds on round trips. ?There are
dropped packets even at low usage rates. ?The jitter across the FR links is excessive when it is greater

ready? (Choose two.)
A. Upgrade the data center to Layer 3 switching.
