Which two networks will require the router to perform a recursive lookup?
** 10.0.0.0/8
** 192.168.2.0/24
What is a hybrid network topology?
A hybrid is a combination of two or more basic network topologies, such as a star-bus, star-ring, or tiered topology.
What situation would it be most desirable to use a connectionless transport layer protocol?
It is desirable in some cases where the time to establish and maintain a connection is either unnecessary or incurs excessive overhead.
Take, for instance, beacons broadcast by either your cellular towers or WiFi access points--these transmissions are multicast and are not intended for a particular recipient, thus there is no reason to set up a connection to any client devices. Any multicast transmission would not need to establish a connection.
In other cases, such as streaming video applications, a connectionless protocol like UDP is used since lost packets are often unusable once they fail to reach the recipient by a given deadline. An application using UDP transport will be able to ignore the lost packets or explicitly request important packets again, whereas a connection-oriented transport layer like TCP would retransmit stale packets and also throttle bandwidth in response to lost packets.
Which two statements describe static routes?
*They require manual reconfiguration to accommodate network changes.
*They are identified in the routing table with the prefix S
IPX/SPX
NetBEUI
Assuming no subnetting what are valid Class B host addresses?
A classful class B network has a network range of 128 - 191. For host addresses, anything that is legal for an IP address in the last 2 octets would be a valid host address for a class B with no subnets.
What are the key factors to consider when grouping hosts into a common network?
* Purpose * Geographic
location * Ownership
What is port forwarding in networking. What is the main purpose of port forwarding in router?
Well Port Forwarding is really only, opening ports and making them special to let a one connection on it. The main purpose for me is for gaming, you need to port forward for a game to run a dedicated server if the game allows, like Quake 3 arena, or GTA's, or Call of Duty's ect.
Why do most network use distributed processing?
The basic idea of using a network is to share resources; therefore, by its very definition you are using a form of distributed processing. There is no way around that, because when you share resources you are distributing the information, this way across a network.
How do you daisy chain routers?
Routers perform DHCP, which means the router acts as the "owner" of the network. If a router set it's own IP address to 192.168.1.1, then it will likely assign IPs to computers connected to it in the 192.168.1.x range. If you plug another router into your first router, the second router might have the IP 192.168.2.1, and then assign IPs in the 192.168.2.x range. This is what you want to avoid. Having all your computers on the same 192.168.x network is necessary.
You essentially want to use your second router as a switch. To do this, disable DHCP in the routers admin UI. Then, instead of plugging the source cable (coming from your first router) in the "Uplink" port, plug it into one of the regular 1, 2, 3, 4 etc ports. This will enable your router to pass along IPs from your main router, rather than assign it's own. Plug other devices into 2, 3, 4, etc. You've essentially bridged your routers.
What happens when you Bridge WAN with a LAN?
LAN users get access to internet or can communicate with others LAN connected to WAN.
Common way of sharing resources on a peer-to-peer network is modify by?
Modify the file-sharing controls using the computer's operating system
What is IP Subnet Planning and why is it important?
IP subnet planning is a way to manage how TCP/IP networks are split. It is important because switched networks can operate without intervention for long periods of time but TCP/IP Internets need much support and tuning. Subnet planning covers the need for TCP/IP management efforts and expertise.
Where are internet cards available?
If you're talking about "wireless internet cards" Or Visa Check Cards to use online? www.wireless.att.com/businesscenter/solutions/wireless-laptop/modem-cards.jsp Here is another internet card people refer to: http://www.123greetings.com/friendship/net_pals/
One disadvantage of telnet is that it is not secure, meaning people can read your passwords and other sensitive information. It is outdated and has no colors. It is fairly hard to use.
Can a packet be forwarded without a route?
No packet can be forwarded without a route. Whether the packet is originating in a host or being forwarded by an intermediary device, the device must have a route to identify where to forward the packet.
