e-mail 75 kbps
internet 200 kbps
Oracle 500 kbps
FTP 250 kbps
Total 1025 kbps
The customer has allocated 25% of the WAN link for routing updates and other overhead. They would like
to increase the number of samples encapsulated in each PDU to 40 ms. You have calculated 6 bytes of
overhead for Frame Relay, no cRTP, and the use of the G.711 codec.
How many simultaneous calls could be placed on this link?
A. 0 calls
B. 1 call
C. 2 calls
D. no more than 5 calls
E. no more than 10 calls
F. no more than 20 calls
Answer: B
9. Refer to the exhibit. A QoS strategy has already been deployed on the LAN. Choose three WAN QoS
best practices that should be used over the WAN link. (Choose three.)
