Question
Your company has just added R3 router to the existing network. But currently no routing updates are being exchanged between R3 and the network. All other connectivity, including Internet access are working properly.
The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.
All passwords on all routers are set to cisco.
IP addresses are listed in the chart below.

CCNA Configuration SIM Question

Question
Refer to the topology
Configuration_Sim.jpg
TUT Company recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring RIPv2 routing using the router command line interface (CLI) on the R2-TUT.
Name of the router is R2-TUT
Enable-secret password is cisco1
The password to access user EXEC mode using the console is cisco2
The password to allow telnet access to the router is cisco3
IPV4 addresses must be configured as follows:
Ethernet network 213.123.20.128/27 – router has last assignable host address in subnet
Serial network is 200.0.1.16/28 – router has last assignable host address in the subnet. Interfaces should be enabled.
Router protocol is RIPv2

CCNA NAT SIM Question

Question
You are tasked to configure Internet access on a router. The ISP has provided the company six public IP addresses of 198.18.184.105 198.18.184.110. The company has 14 hosts that need to access the internet simultaneously. The hosts in the company LAN have been assigned private space addresses in the range of 192.168.100.17 – 192.168.100.30.
The following have already been configured on the router：
– Router basic configuration
– Interfaces have been configured for NAT inside (Fa0/0) and NAT outside (s0/0)
– The appropriate static routes have also been configured
– All passwords have been temporarily set to “cisco”
Tasks:
+ Use NAT to provide Internet access to all hosts in the company LAN.
+ Name the router TUT
+ Inside global addresses: 198.18.184.105 198.18.184.110/29
+ Inside local addresses: 192.168.100.17 – 192.168.100.30/28
+ Numer of inside hosts: 14

C is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language. It keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers. Audience This tutorial is designed for software programmers with a need to understand the C programming language starting from scratch. This tutorial will give you enough understanding on C programming language from where you can take yourself to higher level of expertise. Prerequisites Before proceeding with this tutorial, you should have a basic understanding of Computer Programming terminologies. A basic understanding of any of the programming languages will help you in understanding the C programming concepts and move fast on the learning track. Execute

Properly defining the fields in a table is important to the overall optimization of your database. You should use only the type and size of field you really need to use; don't define a field as 10 characters wide if you know you're only going to use 2 characters. These types of fields (or columns) are also referred to as data types, after the  type of data  you will be storing in those fields. MySQL uses many different data types broken into three categories: numeric, date and time, and string types. Numeric Data Types: MySQL uses all the standard ANSI SQL numeric data types, so if you're coming to MySQL from a different database system, these definitions will look familiar to you. The following list shows the common numeric data types and their descriptions: INT  - A normal-sized integer that can be signed or unsigned. If signed, the allowable range is from -2147483648 to 2147483647. If unsigned, the allowable range is from 0 to 4294967295. You can specify a widt

Android operating system is a stack of software components which is roughly divided into five sections and four main layers as shown below in the architecture diagram. Linux kernel At the bottom of the layers is Linux - Linux 3.6 with approximately 115 patches. This provides a level of abstraction between the device hardware and it contains all the essential hardware drivers like camera, keypad, display etc. Also, the kernel handles all the things that Linux is really good at such as networking and a vast array of device drivers, which take the pain out of interfacing to peripheral hardware. Libraries On top of Linux kernel there is a set of libraries including open-source Web browser engine WebKit, well known library libc, SQLite database which is a useful repository for storage and sharing of application data, libraries to play and record audio and video, SSL libraries responsible for Internet security etc. Android Libraries This category encompasses those Java-based li
