31- What is BIA ?

Burn in Address other name is MAC address

32- What is Size of IPv4 MAC Address?
48 Bits

33- Why MAC address called Physical address?
Because it’s not changeable

34- Who controls MAC address uniqueness and how
IEEE (Institute of Electrical Electronics and Engineering) Controls its uniqueness.
They divide 48 bits MAC address in two parts. First 24 bits part called OUI (Organizational unique identifier) and other 24 bits are device code.

35- How we can see MAC address from DOS Prompt?
ipconfig/all

36- Why IP address called logical address?
Private IP called logical address because they are change able.

32 bits
38-What is Syntax of IPV4
. DOT

39- How many types of IPS?
Three Types of IP
1- Public
2- Private
3- Special IP

40- What are the ranges of private IPS?
A Class = 10.0.0.0 – 10.255.255.255
B Class = 172.16.0.0 – 172.31.255.255
C Class = 192.168.0.0 – 192.168.255.255

169.254.0.0 through 169.254.255.255 (APIPA only)

CCNA Access List Sim 1

Question

A network associate is adding security to the configuration of the Corp1 router. The user on host C should be able to use a web browser to access financial information from the Finance Web Server. No other hosts from the LAN nor the Core should be able to use a web browser to access this server. Since there are multiple resources for the corporation at this location including other resources on the Finance Web Server, all other traffic should be allowed.

The task is to create and apply an access-list with no more than three statements that will allow ONLY host C web access to the Finance Web Server. No other hosts will have web access to the Finance Web Server. All other traffic is permitted.
Access to the router CLI can be gained by clicking on the appropriate host.

All passwords have been temporarily set to “cisco”.
The Core connection uses an IP address of 198.18.196.65
The computers in the Hosts LAN have been assigned addresses of 192.168.33.1 – 192.168.33.254
Host A 192.168.33.1
Host B 192.168.33.2
Host C 192.168.33.3
Host D 192.168.33.4
The servers in the Server LAN have been assigned addresses of 172.22.242.17 – 172.22.242.30
The Finance Web Server is assigned an IP address of 172.22.242.23.
