Could i see pictures of the three most common network topology?
The three most common are ring, star, and bus.
Here is a simple picture of the networks.
What is the yogscast server address?
they have 2 that i know. one.yogiverse.com and two.yogiverse.com but they are offline
Describe at least five key principles in the design of layered network architecture?
Principles are not advantages or disadvantages of the layered approach, principles are behind the layered approach
Principles:
- Data transmission error free.
- Minimum time for route discovery.
- Communication between layers through primitives.
- Congestion control for minimum delays and retransmission.
- Minimum effort in replacing new layer in the existing network layers.
P E R T is the acronym for Product Evaluation Review Technique. C P M signifies Critical Path Method.
What does lease expires mean in local area network connection status?
Means that each ip addresse will change say from 192.168.1.59 to 192.168.1.23
Port 447 is assigned to the service:
DDM-Distributed File Management
This refers to the speed of each port. Combined, an 8-port switch will have a capacity of 1.6Gbps (100Mbps inbound and outbound per port), for example. The switching fabric is said to have this combined capacity.
What identifiers are added at the transport layer during the encapsulation process?
two applications communicating the data
The show interfaces command could be issued to determine if the router has experienced an input or output error.
How does a repeater extend the length of a lan?

Does LAN use peer-to-peer or server-based networking?
It can be set to both
Lan's typically use server based networking, but a Lan can have no server at all, just workstations that link together.
A local area network for a building?
Since local area networks are small in size and geographic location, a building may contain several LANs connected together with routers. It is very common to have many LANs within a building, either as true physical LANs or logical VLANs through managed switches.
How can a switch help reduce network security problems?
Switches use routing table which does allow to brandband your connection requests how hubs do. It protects you from sniffing programs.
Which network access method relies most often on a star-wired bus physical topology?
A star-wired bus is a hybrid topology (more than 1 type of topology). There is no particular access method that requires or relies on that type of hybrid.
When a PC reports it has used an automatic private IP address what can you assume about the network?
You may assume that there is a problem with network connectivity somewhere. You might also assume that the DHCP server is not operating because an APIPA address would only be used if the device could not receive an address via DHCP protocol.
In networking terms what is reliability?
in networking terms, reliability means ensuring that each segment that the source send arrives at the destination
For a router to forward packets with a destination on a network not in the routing table the gateway of last resort must be set. This can be done on a cisco router by going to global configuration mode and entering the following: Router(config)ip route 0.0.0.0 0.0.0.0 s0/0/0 this will cause the router to forward all packets with a destination not in the routing table out serial interface 0/0/0.
After setting up one or more scope sof contiguous address ranges and activating each scope to configure your DHCP server, you must then authorize your server as a security precausion.
Example of public and private ip Address?
A public ip address can be anything that is not in these three ranges. 10.0.0.0 - 10.255.255.255, 172.16.0.0 - 172.31.255.255, or 192.168.0.0 - 192.168.255.255.
How many connections are required by a fully-connected network with five stations?
A fully connected network follows the formula c=n*(n-1)/2, where n is the number of nodes and c is the number of connections. So, for a network of 5 nodes (stations) there would be 5*4/2=10 connections.
