1. A company wants its network to be configured and if necessary upgraded to enable it to handle the addition of VoIP traffic along with other IP data. During the network assessment you identify: ?The core of 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 than 30 milliseconds. Which two changes should occur before the customer’s network is declared VoIP – ready? (Choose two.)
A. Upgrade the data center to Layer 3 switching.
B. Modify the 802.1p values on the VLANs to reduce the dropped packets to the remote sites.
C. Increase the Committed Information Rate (CIR) to guarantee that enough bandwidth is available to the remote sites.
