On a Cisco switch is the command :-copy running-config startup-configavailable, as on a router ?I recall reading that on changing the running config on a 2950 or 1900 Catalyst switch, it is written immediately to NVRAM, so the above command is NOT av...
Can anyone please clarify the split horizon rules for Frame Relay. I have read conflicting descriptions from different sources.As I understand it, for the main physical interface configured with encapsulation type Frame Relay, split horizon is disabl...
Does VTP require that a switch-to-switch link is configured as a trunk link rather than an access link ? Or can it send its advertisements over an access (non-trunk) link ?And how about Spanning Tree Protocol (STP) ? Does it require a trunk between t...
Does the order of OSPF network statements matter ? Ie. do they work like an ACL where more specific statements must come come before more general ones ?For example is there any difference between entering :-network 192.168.129.96 0.0.0.3 area 40 netw...
Imagine a scenario in which a router is connected to a local ethernet network, and to other routers on an internetwork. My question is regarding what is stored in the ARP cache on a host on the local ethernet.As I understand it entries in the ARP cac...
Thats what I thought. The multiple choice answer will only accept a switch name though. I attach a diagram of the topology. Only SW-AC3 can be connected to, via the console connection shown.
Hi, thanks for your reply. In the question it does not allow you to telnet or console onto the next switch. Only one switch out of the four can be connected to. It is this reason I think it is not possible to determine the root switch for sure withou...
Hi, I have encountered a similar problem with a 4 switch simulation, which gives access to only SW3, and asks which switch is the root bridge.By running show spanning-tree command I can see the MAC address of the root bridge, and the root port of SW3...
Thanks for your comment Rick. I took CompTIA A+ and N+ exams last year, and I note that these also include this type of question. Maybe its a general feature in certification exams.
Thanks for all replies. The final conclusion that OSPF has no hop count limitation is in keeping with the answer expected in the practice test question. Some routing protocols DO have hop count limits, namely RIP has a limit of 15, and IGRP has a lim...
