An expanding company is deploying leased lines between its main site and two remote sites. The bandwidth of the leased lines is 128kb/s each， terminated on different serial interfaces on the main router. These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs， and has therefore reserved sufficient bandwidth in a low latency queue on each interface for the VOIP traffic. Users now complain about bad voice quality although no drops are observed in the low latency queue.What action will likely fix this problem？（）
- A、mark VOIP traffic with IP precedence 6 and configure only ’fair-queue’ on the links
- B、configure the scheduler allocate 3000 1000 command to allow the QoS code to have enough CPU cycles
- C、enable class-based traffic shaping on the VoIP traffic class
- D、enable Layer 2 fragmentation and interleaving on the links
- E、enable Frame Relay on the links and send voice and data on different Frame Relay PVCs

第8题：
(d) Calculate the ex dividend share price predicted by the dividend growth model and discuss the company’s
view that share price growth of at least 8% per year would result from expanding into the retail camera
market. Assume a cost of equity capital of 11% per year. (6 marks)
(d) The dividend growth model calculates the ex div share price from knowledge of the cost of equity capital, the expected growth
rate in dividends and the current dividend per share (or next year’s dividend per share). Using the formula given in the
formulae sheet, the dividend growth rate expected by the company of 8% per year and the decreased dividend of 7·5p per
share:
Share price = (7·5 x 1·08)/(0·11 – 0·08) = 270p or ￡2·70
This is the same as the share price prior to the announcement (￡2·70) and so if dividend growth of 8% per year is achieved,
the dividend growth model forecasts zero share price growth. The share price growth claim made by the company regarding
expansion into the retail camera market cannot therefore be substantiated.
In fact, a lower future share price of ￡2·49 was predicted by applying the current price-earnings ratio to the earnings per
share resulting from the proposed expansion. If this estimate is correct, a fall in share price of 7% can be expected.
The share price predicted by the dividend growth model of ￡2·70 would require an after-tax return on the proposed expansion
of 11·66%, which is more than the 9% predicted by the Board. The current return on shareholders’ funds is 7·5% (4·5/60),
but in 2005 it was 12·8% (7·3/57), so 11·66% may be achievable, but looks unlikely.
Since the market price fell from ￡2·70 to ￡2·45 following the announcement, it appears that the market does not believe
that the forecast dividend growth can be achieved.
