| I haven't read about Frame Relay for over a year now so let's see if I still know about it. Please don't consider my answers as correct until others tell us what they think then we could discuss and see who's right.
1. ABE
2. AB
3. AD | |

| Out of curiosity (I'm not taking CCNP just surfing through), I would have thought that ADSL would have been more likely than ISDN BRI. (Q1). Is that not the case then? | |
| sukuvi 2003-07-26, 10:15 am |
| I believe the reason ADSL is not a choice is due to distance requirement between CO or the exchange and the subscriber. I can't remember what the distance is but it's got to be within a max, beyond that it won't work.
You'll notice this as well in the statistics of broadband internet access subscribers. There are more cable subscribers than there are for DSL subscribers and for the same reason.
SureshHomepage, what do you think? | |
| SureshHomepage 2003-07-26, 8:51 pm |
| Yes Sukuvi...I also thoguht the same!
I was thinking of both ADSL as well as the Cable Modems as possible options but I am left with to select only one among them.
ADSL has line and distance constrains....also as you said cable modem is more popular than ADLS in US and Ofcourse NOT in Asian countries, Australia and Asiapacific where ADLS is more popular to my knowledge.
I selected the answer as cable modem for the simple reason I thought that the questions setters could be housed at Cisco's San Jose office! True?! | |

| Interesting to think that your physical location on the planet would have a bearing on the answer to this question.
In the UK, I think ADSL is more popular than ISDN these days, though I am happy to be corrected. So my answer would have been AEF.
Thanks for the replies! | |

| I have to agree with the answer from thebonzodog on question one. It didn't state any distance from a serving central office. In California, I haven't seen too many people using ISDN.

| Hi,
Eventually anyone would like to answer in a way that would fetch him scores!
The questions was to to select 3 answers among 6 choices. ISDN and Async dial-up has obviously been considered as possible options and included on the answers list.
When you think of providing a portable dial-up connectivity you can not strike out ISDN as an option though ADSL advantaged more in UK! I find little bit of an unprofessionalism here. A considerably experienced WAN design engineer wouldn't think that way. You can not strike out ISDN in the name of ADLS's popularity.
Anyway the debate here to select the 3rd answer, whether to include ADSL or Cable modem and NOT ISDN vs. ADSL.
I preferred Cable Modem rather than ADSL. |
