ITE 1 Chapter 12 Notes
1. If your Date/Time is wrong; whats the problem?
a. CMOS Battery
2. If you install a 2nd HDD what do you have to do?
a. Set to Master/Slave (IF PATA or IDE HDD) and set to jumpers
b. No jumpers (IF SATA)
3. What does SATA require?
IPv6 Addr/prefixIPv6 Next Hop Exit Interface
Accursive > Exit Interface
Uses Next Hop Addr
Uses Exit Int
Must have ipv6 unicast routing
Next hop Ipv6 route 2001:
Best path is selected by a routing protocol based on the value or metric it uses to determine the
distance to reach a network
o A metric is the value used to measure the distance to a given network
o Best Path to a network is the path with the l
CCNA 2 Chapter 8.5 Notes
OSPF has 3 data bases for IPv4 + 3 for IPv6
Link state Database (Topology Table)
Adjacency Database (Neighbor Table)
Forwarding Database (Routing Table)
How can we see it?
o With the command: Show ip OSPF databases
What does OSPF
1. Why would you use a Passive-Interface command?
a. Use on int without routers
b. Prevents routing updates going in that direction
2. Why do we use Static Routing
a. Small networks
b. Uses less bandwidth (Les resources)
c. Used for stub networks
Personal Computer Systems
Cases and Power Supplies
Influences the motherboard form factor choice
Must allow for good air flow
Available in different sizes
Provides power to all computer components
Must be chosen based on current and
Flexibility Uses all network resources available to provide data traffic load sharing.
Resiliency Provides a way for the network to always be accessible.
Modularity Allows networks to expand and provide on-demand services.
