Cisco CCNA lab kit Buying a Cisco CCNA lab kit for home is the best way to be completely prepared for Cisco exams. Many CCNA candidates prefer to buy kits where one can get multiple routers and switches, along with all the cables and other connection devices needed. It is a good idea to keep few things in mind when purchasing Cisco CCNA lab kitfor home. The problem arises when one first starts to use Cisco CCNA lab kitwithout knowing anything about the lab kit. Always keep in mind to use one transceiver per AUI port on a Cisco router, so if you're getting routers with two AUI ports in total then you wonâ€™t need five transceivers in the kit. It doesn't matter to have one spare rather than having three which is too much.More importantly, do not buy Cisco CCNA lab kit with old CCNA or CCNP study guides material. There are kits with books that are three years older andwill be of no use to the candidate. If you see a Cisco CCNA lab kit that looks good but also comprises of books or manuals then just ask the vendor for a price that doesn't include the books. Watch the new IOS version if you have access to IOS upgrades, and preferably work on with the IOS version that is present on the routers and switches after you buy the Cisco CCNA lab kit for a while. There is no need of the latest and utmost IOS version for CCNA study, but it is advisable not to buy routers with IOS versions beginning with "10" unless the IOS is upgraded. Purchasing a Cisco CCNA / CCNP Home Lab kit is one of the best investments one will make in his career. Researchingis necessary while purchasing the kit, as one will be on his true path to Cisco success in the exam room as well as on the network. For CCNA and CCNP home labs2503 routers will be fantastic. They come with two serial interfaces, allowing the person to connect one interface directly to another router. One also needs a DTE/DCE cable for connecting another interface to a frame relay switch according to oneâ€™s choice for the purpose. If a frame relay switch is not present then connect a 2503 directlyto two other routersvia the serial interfaces.Transceivers are pretty cheap and readily available from Cisco resellers and eBay sellers, so one can just pick for each 2503 router online. The 2503 routers come with a BRI interface. Even though it has an ISDN simulator present one may choose to add another later.This allover makes 2503 a great strategy for future lab expansion.
