CCENT Exam Cost: Plus How to Register Online
Currently (Sept. 2010) the CCENT Exam is going to cost you $125 USD. If you live in another country other than the United States I’ll show you how you can find out how much it will cost you to take the CCENT Exam in your country’s native currency.
First of all I just want to say that if you think that the CCENT Exam is priced too high or that it isn’t worth getting, it is well worth the investment. Because of the important skills you learn along the way of becoming a CCENT you will become a lot more valuable than other people looking for jobs without it. It also is a great stepping stone toward getting your CCNA. Also just within the first month of getting a job or a pay raise (if you already have an IT job) you will earn more than enough to pay off the original investment of $125 plus study materials.
What you need to know about VLAN Trunks for the CCNA Exam
Understanding how VLAN Trunks work is essential to you passing the CCNA Exam. In this post I’m going to talk about VLAN Encapsulation with 802.1Q, and all the details about the VLAN Trunking Protocol VTP.
Trunks are needed in switching networks with VLANs in order for hosts within different VLANs to still communicate with each other. When you create a VLAN you are supposed to maintain a 1 to 1 ratio with the number of subnets you have. Which means if you have 4 VLANs you should also have 4 subnets. Since each VLAN is in a different subnet they are in different networks and for devices in different networks to communicate with one another a Layer 3 device such as a router is needed. Interfaces on switches by default can only be assigned to one VLAN at a time. So, in order for you to send data about 4 different VLANs configured on a switch to a router you need to configure an interface to be a trunk link. Trunk links are able to send data for many different VLANs at one time. In order to keep them from getting mixed up they tag the switch frame.
What you need to know about VLANs for the CCNA Exam
VLANs are another important topic on the CCNA Exam that you will need to become very familiar with. VLAN stands for Virtual Local Area Network which means that you can now segment a LAN logically at the Layer 2 level rather than physically based on geographic location.
Benefits of VLANs
Having this capacity to logically break up network segments VLANs provide many benefits. They are able to break up broadcast domains, keep network failures from affecting the entire network, increase security, and reduce administrative overhead.
What you should know about PPP for the CCNA Exam
Point-to-Point Protocol or PPP for short is a layer 2 protocol for sending layer 3 packets over synchronous (ISDN) and asynchronous (dial-up) WAN links. Just like for every topic on the CCNA Exam there are many new terms that you will need to learn and understand about PPP. So, lets begin! Link Control Protocol The [...]
What you should know about Frame Relay for the CCNA Exam
Frame Relay is a protocol used to establish WAN connection between remote locations. Frame Relay operates at Layers 1 and 2 of the OSI Model. There are many details to Frame Relay that you will need to understand in order to be prepared for the CCNA Exam and the ICND2 Exam. Virtual Circuits Frame Relay [...]
