B. DSP resources will only be required at the regional sales offices to convert G.711 to G.729 for
C. DSP resources will be required at the central site to support conferencing, and at the remote

In their busiest day, AMFAB has 35,422 total minutes of external traffic.
Using the answer you determined in question 1, use the following erlang chart snippets to
determine the number of T1 circuits needed to connect AMFAB to the PSTN, assuming one call
blocked in 100 attempts is acceptable.
(See erlang chart at the bottom of the topology.)
C. They only need six trunk lines. Purchasing a T1 would be a waste of money.
G. They only need five trunk lines. Purchasing a T1 would be a waste of money.
AMFAB Environmental Consulting (AMFAB), an environmental consulting company, based near
Atlanta, Georgia, uses a PBX for its campus phone system. The PBX cannot support all the new

According to best practices, how should the Redmond traffic be classified and marked so that all
IP traffic will be handled properly?
A. Mark voice bearer and signaling traffic as CS5; Oracle as CS4; UNIX RPC as CS3;
Exchange/Outlook as CS2; HTTP as CS1; and all remaining traffic as BE
B. Mark voice bearer and signaling traffic as EF: Oracle as AF41; UNIX RPC as AF31;
Exchange/Outlook as AF21; HTTP as AF11; and all remaining traffic as BE
C. Mark voice bearer traffic as AF41; the voice signaling traffic as AF31; UNIX RPC and Oracle
traffic as AF43; and HTTP and Exchange/Outlook as best effort
D. Mark voice bearer traffic as EF; Oracle traffic as AF41; UNIX RPC as AF43; voice signaling
traffic as AF31; Exchange/Outlook traffic as AF21; and the HTTP traffic as best effort
