Tokenring [7:72470]
Hi, I know that this should be a easy question, I think that the answer is B. But the book says A, what do you think the answer is? If you could also provide a link for a detailed answer that would be good. What would happen on a simple ring network if one of the users turned off her workstation? a. Only her workstation would lose connectivity. b. None of the workstations would lose connectivity. c. The workstations on either side of hers in the ring would lose network connectivity. d. The network would fail Answer: ? Thanks in advance Dj - Yahoo!

Exam changes [7:71982]
Hi, I want to get hold of the Cisco Learning Product folders you get when you sit on a Cisco official learning course. I find them much better to read then the Cisco press books. Does anyone know if I can purchase them from anywhere, or that if they are only available when I attend a official Cisco course. The other reason is that with all the exams changing (CCNP/DP/SP), Cisco press take a while for the books to come out, but with Cisco folders you get on the course, I guess they will become available much earlier. Any ides? Thanks in advance, -Dj - Yahoo!

Thanks in advance for your help DJ Bosco Sachanandani wrote: >From what I understand (and have done in a similar way in my network) when the WYSE terminal sends a request for the remote host IP, and when that reaches the router, the router in trying to route the packet to the remote network (based on the routing table) will foward the packet to the ISDN interface. When the ISDN interface realises that there is a packet for the remote network, it will dial out automatically using the phone number and authentication credentails.

IP addressing [7:70057]
Hi, Can someone please check below, to see if I am going in the right direction. I have 3 sites A B C A wants 500 users. B wants 2000 users c unknown up to 200 IP address range I have is as follows:- 10.225.200.0 to 10.225.219.255 I have worked the following:- For A the range is 10.225.200.0 to 10.225.201.255 with a subnet mask of 255.255.254.0 or is it 255.255.255.0 For B the range is 10.225.202.0-255 10.225.203.0-255 10.225.204.0-255 10.225.205.0-255 10.225.206.0-255 10.225.207.0-255 10.225.208.0-255 All with a subnet mask of 255.255.248.0. For C the range is 10.225.209.0-255 to 10.225.210.0-255 subnet mask of 255.255.254.0 if all on single network will all these talk without any problems and I still have 211 through to 219 free.

HDLC [7:66324]
Hi, I have a couple of queries regarding HDLC and Frame Relay. I gather they're both forms of data encapsulation for data and basically this means putting the data in headers and trailers to identify to the next layer or computer how to deal with the data. Please advise whether this is correct. If this is correct, could you please advise under what circumstances HDLC and Frame Relay are used in a real world environment? Do they function in their own right, or are they part of software or hardware or a protocol? I see that HDLC is for point to point transfer only; presumably this means that if a router is using HDLC it can only talk directly to one device out a single interface but with FR, it can send frames over a LAN-like structure? I seem to be in some confusion as to where these two things fit in; the rest of the two chapters (3 and 4) seem fine, I just keep contradicting myself over these two things. I'm sure it's one of those blindingly obvious things that will be really simple to understand once someone sets me straight - I think I'm interpreting these things differently each time I read about them.

PRI [7:64999]
Hi All, Quick question I hope you can help me with. How many D channels does a PRI have? I always thought it was two, but its states 1 in most places. Text taken from the CCNP remote access guide (to make it more confusing): there are 30 timeslots, leaving 2 timeslots for signalling and framing. Timeslot 0 is used for framing and timeslot 16 is used for signalling (counting 0-31). E1 PRI makes use of this same principle. Timeslot 16 is the D channel and timeslot 0 is used for framing information. Please advise. Regards,DJ - With Yahoo!

Multicast...please help [7:51822]
Hi I have a question regarding the election of the LAN router which is supposed to send the queries for multicast accesses. In chapter 8, page 302, IGMPv2 querier election, it is mentioned that the router with the lowest IP address is elected as multicast querier. In Chapter 9, page 336, it is mentioned that the DR (designated Router) elected is the one with the highest IP address. "The DR is responsible for sending IGMP host-query messages to all host on the LAN". Could you please help me understand the differences between the two above cases, because for me, routers seem to have the exactly same role but are elected an opposite way... thanks DJ - Get a bigger mailbox -- choose a size that fits your needs. http://uk.docs.yahoo.com/mail_storage.html Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=51822&t=51822 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
OSI...Please help... [7:51235]

In the example :access-list 101 deny tcp host 172.16.3.10 172.16.1.0 0.0.0.255 eq ftpaccess-list 101 permit ip any any Do the terms "tcp" and "ip" refer to the individual protocols or the stack ? I assume they refer to the individual protocols as you could substitute them with "udp" or "icmp" but then surely the last statement would allow only the individual "ip" protocol and therefore all other packets such as tcp , udp, icmp would be filtered. Or does tcp , udp , icmp get through because it is encapsulated in ip ?
