1. How2Pass, a fast growing company with one central headquarters site and 3 regional offices, is looking for a scalable WAN technology. Current plans include adding 7 additional regional offices with all sites requiring continuous connectivity. The current HQ router has no free ports. Which of the following WAN technologies would meet the requirements of How2Pass?

A. Dedicated PPP/HDLC links
B. Frame Relay
C. ISDN-BRI
D. ADSL
E. Broadband cable service

It says the answer is D what i never seen anything mentioned anywhere else about ADSL I was thinking the answer was B, does any one know the correct answer

2. You are required to troubleshoot the WAN link between the Cisco main office at Boston and the Cisco remote office at Rio De Janerio. A Cisco router that was providing FR connectivity at Rio de Janerio site as replaced with a different vendor's frame relay router. Connectivity is now down between the Boston and Rio de Janerio site. What is the most likely the cause of the problem?

A. Mismatched LMI types
B. Incorrect DLCI
C. Mismatched encap types
D. Incorrect IP address mapping

I am thinking it is either A or C but not sure, do you know?

I'd go with you on both counts, the second question, well that is usually the biggest problem, especially mismatched encapsulation.......

The first answer is B. You can configure more subinterfaces than you'd ever need to use and have many PVC's. The second answer is most likely encapsulation type since Cisco uses a proprietary Frame Relay encapsulation and the LMI type is autosensing.
