Network Address Translation Explained for CCNA. Network Address Translation (NAT) is a method of mapping one IP address space into another by modifying network address information in the IP header of packets while they are in transit. i.e. Basically, for an IP packet in transit, the IP address is changed from one to another in a pre-determined manner.

Next question would be the need to translate (or map) one IP to another. There are multiple reasons for this translation as detailed below: Translation of private addresses into unique public addresses when accessing the Internet: Many organizations use private address space internal to the organization with a view of conserving the IP addresses. Now that we know some of the cases where network address translation is useful, we discuss various types of NAT: Static NAT: Maps an unregistered IP address to registered IP (globally unique) addresses on one-to-one basis. Below are some of key terms related to NAT which play important role in IP address Translations: A Labsim with Examsim. Back to simulationexams.com A+ practice tests with labsim home page.

About the CompTIA 220-1001 A+ Core 1 exam CompTIA's 220-1001 certification exam is the first of two exams to be passed before earning your A+ certification. This exam measures the necessary competencies of an entry-level IT professional for necessary hands-on experience in working with configuring and/or troubleshooting Windows PCs. The 220-1001 certification tests your understanding of computer technology, networking and security, as well as the communication skills and professionalism that will be required in the field or within an organization.

The second exam required to earn CompTIA's A+ certification is A+ Core 2 (220-1002) exam. The 220-1001 and 220-1002 exam exams together enable one to achieve A+ Certification. A+ certification is ISO 17024 Accredited (Personnel Certification Accreditation). What to expect in the CompTIA A+ Core 1exam? This test consists of multiple-choice questions.

Spanning Tree Protocol (STP) in Local Area Networks (LANs) What is Spanning Tree Protocol: In computer networking, data packets are forwarded from one network node to another as the packet travels from source to destination. However, in Ethernet networks, it is quite possible that these packets (in strict sense, these are called frames as they traverse at layer-2 of the OSI layer format within LAN) have multiple paths to the next hop address. Consider the simple figure given below: Assume that Frame 1 originating at SwitchA needs to reach destination SwitchD. As may be seen in the adjacent figure, Frame 1 originating a SwitchA has multiple paths to reach SwitchC.

If the redundant path is not blocked, it may result in a loop. i.e. the same frame Frame 1 may be broadcast at SwitchC and again come back via SwitchB. Remember that bridges and layer-2 switches natively send frames to all ports other than the port on which the frame is received. Note: STP allows redundancy in Layer-2 networks. Default priority value is 32768. Example: 1. References: Feed Fury Feed of Anand Software. AnandSoft on Reddit. IOS Apps for Compai A and Cisco CCNA.

Network Simulators for Cisco and Juniper Networks.

Network Simulators provide a virtual networking environment so that one can learn to design, configure, and troubleshoot networks consisting of virtual devices. The following are the parts of a virtual network: Virtual devicesRoutersFirewallsSwitchesWorkstationsVirtual connetorsSerial connectorsEthernet RJ-45 connectorsConsole and Aux portsISDN connectorsVirtual cablesEthernet cablesSerial cablesConsole/Aux cablesCable adapters, etcThere is no physical hardware and therefore there is no obsolescence. It costs fraction of the cost of actual networking devices. Remember, most of the networking devices are very expensive when it comes to gigabit speeds. However, you don’t need to use a gigabit speed device just for learning how to network.Labs – The network simulator comes with dozens of labs on various topics including subnets, IPv6, routing protocols such as RIP, EIGRP, OSPF, BGP, etc.Simulate NAT, VPN, ACLs, and more and see if you got the configuration properly.
