- What is a Broadcast Storm
- 6. Name some of the ways of combining TCP/IP traffic and SNA traffic over the same link.
- What does the Ether type code do?
- What is BGP?
- a It differentiates which protocol is being carried by the ethernet frame.
- b Border Gateway Protocol. Currently version 4. BGP is used for routing between networks on the Internet core, it supports many advanced routing features.
- c A broadcast storm means that your network is overwhelmed with constant broadcast or multicast traffic. Broadcast storms can eventually lead to a complete loss of network connectivity as the packets proliferate. If a certain broadcast transmit threshold is reached, the port drops all broadcast traffic. Firewalls are one of the best ways to protect your network against broadcast storms.

- LAN Emulation used to run normal networking over ATM, it emulates the broadcast nature of a LAN over connection oriented ATM.
- Multicasting allows a single message to be sent to a group of recipients. Emailing, teleconferencing, are examples of multicasting. It uses the network infrastructure and standards to send messages.
- The exit-point from one network and entry-way into another network, often the router of the network.
- Domain local groups grant permissions to objects within the domain in which the reside. Global groups contain grant permissions tree or forest wide for any objects within the Active Directory.
- Hub: 1.it is a layer1 device..used to connect various machine on Lan. 2.It forwards broadcast by default. 3.It supports one collision domain and one broadcast domain. 4.it works on Bus topolog resulting less speed. Switch: 1. A layer2 device. 2. Forward broadcast first time only. 3. one broadcast domain & colliosion domains depends on no. of ports. 4.It is based on Star Topology giving 100mbps to every pc on Lan. Router: 1. Does not Broadcast by default. 2. breaks up Broadcast domain. 3. Also called Layer3 switch.
5 True/False Questions
What are the 3 major classes of IP network? → A, B, C, D, E
What mask would you use to supernet two class C addresses → An IPX address is made up of 4 bytes of Network address and 6 bytes of node address and takes the form of ABABABAB.FFFF.FFFF.FFFF. The address is in hexidecimal. The network address is allocated by the network (usually the servers or routers) and the node address is the MAC address of the device.
What is MTU → Border Gateway Protocol. Currently version 4. BGP is used for routing between networks on the Internet core, it supports many advanced routing features.
What is a VPN? → VPN(Virtual Private Network )... these are bascially the logical networks on the physical line... you can have many VPN oveer same line.. Need of VPN arises when your company need to increase the network but don't want to buy any more switches.. take an eg. your dept. your room is packed with employees and ur company need to add 4 more persons to ur deptt. what will they do.. the solution is to create VPN's...you can configure the switch ports in other deptts. and create a specific VLAN of ur deptt.so that the persons can sit there and access to the required pcs.
How many bytes in an IPX network address? → An IPX address is made up of 4 bytes of Network address and 6 bytes of node address and takes the form of ABABABAB.FFFF.FFFF.FFFF. The address is in hexidecimal. The network address is allocated by the network (usually the servers or routers) and the node address is the MAC address of the device.
