CCNA Semester 1 chapter 1

This is CCNA Semester 1 chapter 1 1. Which computer component is considered the nerve center of the computer system and is responsible for processing all of the data within the machine? RAM * CPU video card sound card operating system 2. What are two advantages of purchasing a preassembled computer? (Choose two.. * usually a lower cost exact components may be specified extended waiting period for assembly * adequate for performing most general applications suited for customers with special needs 3. A user plans to run multiple applications simultaneously on a computer. Which computer component is essential to accomplish this? * RAM NIC video card sound card storage device

Lab 1 - CCNA Implementation SIM

This topology contains 3 routers and 1 switch. Complete the topology. Drag the appropriate device icons to the labeled Device Drag the appropriate connections to the locations labeled Connections. Drag the appropriate IP addresses to the locations labeled IP address (Hint: use the given host addresses and Main router information) To remove a device or connection, drag it away from the topology. Use information gathered from the Main router to complete the configuration of any additional routers . No passwords are required to access the Main router. The config terminal command has been disabled for the HQ router. The router does not require any configuration. Configure each additional router with the following: Configure the interfaces with the correct IP address and enable the interfaces. Set the password to allow console access to consolepw Set the password to allow telnet access to telnetpw Set the password to allow privilege mode access to privpw Note: Because routes are not being

Configuring DHCP Server

What is DHCP? The DHCP (Dynamic Host Configuration Protocol) is an Internet protocol responsible for automating the configuration of computers which use TCP/IP. DHCP can be used to assign IP addresses to computers by delivering TCP/IP configuration addresses such as IP address, subnet masks, default routers and DNS addresses. It can also be used to provide information for a number of other services such as printers, time, news and TFTP servers. Config A Cisco router can be configured as a DHCP server to assign IP addresses. The range of IP addresses which can be given out is called a 'pool'. From this pool clients are leased addresses for a given time, after which the lease expires and the client needs to request a new IP address lease. The following config lines show how to setup a DHCP pool of addresses in the 192.168.0.0 IP range: no ip dhcp conflict logging ip dhcp excluded-address 192.168.0.1 192.168.0.50 ! ip dhcp pool 1 network 192.168.0.0 255.255.255.0 default-route

Switching - Introducing Spanning Tree Protocol (STP)

A loop avoidance mechanism called STP has been developed to alleviate the 3 issues above. There are two varieties of Spanning Tree Protcol, STP (802.1d) and RSTP ('Rapid' 802.1w) both work in a similar way. A Spanning Tree Algorithm examines the switched network, and, through a series of decisions (discussed below) places each port in the loop into either Forwarding or Blocking state, therefore breaking the loop. Types of port in STP: Designated Port (DP) Closest to Root i.e. All Ports on the Root Switch. Route Port (RP) One Per Switch. Blocking Port. The process the switches go through to decide which port they place in blocking or forwarding state is governed by the position of a 'Root Switch' (also known as 'Root Bridge'): To decide which switch is the root switch, each switch begins by claiming to be the Root Switch they all send out an STP messages called BPDU's (Bridge Protocol Data Unit). A fight-off happens to determine the fi
