Which of the following WAN technologies will meet the requirements? Answer: D A. Frame Relay B. Broadband cable C. ISDN-BRI D. ADSL E. Dedicated PPP/HDLC links F. ISDN ADSL work by using a modem and is always on. The question tells you that the HQ router has no free ports, so by using an ADSL modem, it will be the best choice for this question. The cable modem would also be a good choice, but without much security, the ADSL is the better answer. The ADSL may be a good solution but actually the CCNA course does not include ADSL technology. Because the network requires continuous connectivity while the head office lack of ports, a subinteface solution with Frame-Relay may be the best choice. A. 是A吗????????
