CCNA ICND2 Practice Tests
SimulationExams.com, recently released CCNA ICND2 (Interconnecting Cisco Network Devices 2) practice tests. ICND2 exam counts toward CCNA certification awarded by Cisco Systems®. CCNA ICND2 isintended for candidates who have experience in configuration and troubleshootingof Cisco networking devices.. The practice tests offered by SimulationExamsprovide a simulated test environment for candidates before appearing for thecertification exam.
The advantages of a simulated exam are:
- Ability to gauge one's preparedness to take actual certification exam
- To strengthen weak areas
- To familiarize oneself with actual exam environment (such as timed test, lab practice, relevant practice questions, etc.)
CCNA ICND2 is one of the two qualifying exams available to candidates pursuing a two-exam option for Cisco Certified Network Associate Certification. To achieve CCNA, one need to pass both CCENT (also known as CCNA ICND1), and the CCNA ICND2 exams. Alternatively, one can obtain CCNA certification by passing a single exam, 640-802.

VTP Trunking Protocol
VLAN Trunking Protocol
VTP sends messages between trunked switches to maintain VLANs on these switches in order to properly trunk.
VTP is a Cisco proprietary method of managing VLANs between switches and runs across any type of trunking mechanism.
VTP messages are exchanged between switches within a common VTP domain.
VTP domains must be defined or VTP disabled before a VLAN can be created.
Exchanges of VTP information can be controlled by passwords.
VTP manages only VLANs 2 through 1002.
VTP allows switches to synchronize their VLANs based on a configuration revision number.
Switches can operate in one of three VTP modes: server, transparent, or client.
VTP can prune unneeded VLANs from trunk links.

Networking Primer -IP Addressing
Example: 192.189.210.078
It is sometimes useful to view the values in their binary form.
192 .189 .210 .078
11000000.10111101.11010010.01001110
Every IP address consists of network identifier and node identifier. The IP network is divided based on Class of network. The class of network is determined by the leading bits of the IP address as shown below.
Address Classes
There are 5 different address classes. You can determine which class any IP
address is in by examining the first 4 bits of the IP address.
- Class A addresses begin with 0xxx, or 1 to 126 decimal.
- Class B addresses begin with 10xx, or 128 to 191 decimal.
- Class C addresses begin with 110x, or 192 to 223 decimal.
- Class D addresses begin with 1110, or 224 to 239 decimal.
- Class E addresses begin with 1111, or 240 to 254 decimal.
Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine. Class D addresses are reserved for multicasting. Class E addresses are reserved for future use. They should not be used for host addresses.
Now we can see how the Class determines, by default, which part of the IP address belongs to the network (N) and which part belongs to the Host/node (H).
- Class A: NNNNNNNN.HHHHHHHH.HHHHHHHH.HHHHHHHH
- Class B: NNNNNNNN.NNNNNNNN.HHHHHHHH.HHHHHHHH
- Class C: NNNNNNNN.NNNNNNNN.NNNNNNNN.HHHHHHHH
In the example, 192.189.210.078 is a Class C address so by default the Network part of the address (also known as the Network Address) is defined by the first three octets (192.189.210.XXX) and the node part is defined by the last one octets (XXX.XXX.XXX.078).
In order to specify the network address for a given IP address, the node section is set to all "0"s. In our example, 192.189.210.0 specifies the network address for 192.189.210.078. When the node section is set to all "1"s, it specifies a broadcast that is sent to all hosts on the network. 192.189.210.255 specifies the broadcast address.
Private Subnets
There are three IP network addresses reserved for private networks. The addresses are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They can be used by anyone setting up internal IP networks, such as an intranet. Internet routers never forward the private addresses over the public Internet.

CCNA Intro and CCNA ICND exams.
See CCNA Intro exam details, and CCNA ICND exam details
Download, and practice CCNA Intro exam questions, and CCNA ICND exam questions.
The combined syllabus for CCNA Intro, and CCNA ICND is close to CCNA. If you are a working professional with atleast 1 or 2 years of experience in networking, it is suggested to take single exam path. If you are completely new to networking, it is recommended to take two-exam path.

CCNA Network Simulator
- Simulate a router
- Simulate a switch
- Simulate a router/switch network
- Design a router/switch network
- Save semi-finished configurations, and reload for later resumption
- Save the work to a text file for later use.
A router simulator is essential for having hands-on practice. Ofcourse, if you can buy routers and switches and make physical network that would be fine, but normally does not justify the costs involved.
CCNA network simulators are available from the following sources:
http://routersimulator.certexams.com
http://www.boson.com/Product/CIS-NS-CCNA-04.html
A comprehensive CCNA trainer is available at:
http://www.certexams.com/cisco/ccna/download/ccna-trainer.html
Normally, the software is available free for demo version, and you need to pay if you want to unlock the full version. The cost range from $150 down to $25 depending on the requirements. Download, and checkout the features available.

A guide to certification exams
I. Benefits of Certification:
Recognition and increased job opportunity
Proficiency in Related Technology
Equipping a fresh out of college candidate to face a job
Increased job security, and remuneration - According to CertMag.com study, certified candidates enjoyed salary increase from 10% to as high as 23%. It is also shown that more the number of certifications (higher the skill level) more the amount of compensation. See the article at www.certmag.com/issues/dec00/feature_gabelhouse.cfm.
II. Leading vendor certifications from Microsoft®, CompTIA®, Cisco®, CheckPoint®, and Prosoft®:
Microsoft®, CompTIA®, Cisco®, CheckPoint®, and Prosoft® are among the leading vendors of IT Certifications. Each vendor, in turn may have different certification tracks. For example, Microsoft has MCSE (For Networkers) track, and MCSD (for Developers) track. Usually, each track has different levels of certification aimed at the beginner, the pro, and the expert. As often said, certification is a journey, and not a destination. In fact, many certifications require re-certification after a pre-determined period of time (usually 2-3 years) to remain certified. Therefore, it is important that you choose your certification track after careful consideration of your career plan. Though there are wide range of certifications available, we confine to a few leading certification tracks: MCSE/MCSA, CCNA/CCNP, A+/Network+, CIW, and CheckPoint CCSA/CCSE.
Anyone, who is interested in pursuing certifications is recommended to go through the article, and choose appropriate certification path. View Complete article at: Guide to IT Certifications and Certification Exams
