OSI Model
• Topology
• Patch cable
• Flow control
• Common layer 2 device
• Best path
• Purpose of Layer 2 devices
Router Configuration
• Packet forwarding
• Administrator entries to manipulate the
routing table
• Split Horizon operation
Routing Protocols
• Which routing protocol uses link-state
advertisements (LSAs)?
• Link-state routing updates
• Route of last resort
• RIP updates occur every ___
• RIP metric
• Routers use _____ to maintain tables
• Routing protocol used to communicate between
autonomous systems
Routing Protocols
• Another term for shortest path first routing algorithm
• Configuring IGRP
• Split horizon
• IGRP routing updates
• IGRP hop count
ACLs
• A packet that does not match any of the tests in an
access list
• A wildcard mask bit of "0" means _________.
• 0.0.0.0 255.255.255.255
• Access list to permit or deny part of a protocol suite
• If inbound or outbound is not specified
• Wildcard mask for a host range of a subnet
ACLs
• Extended access lists should be placed ____
•
A numbered access list in the range of 800-899
• What are Access Control Lists?
• In which router mode are access lists created?
Network Configuration
• The first step in LAN design
• Alleviate congestion
• Time necessary to move a packet from the data link
layer to the physical layer
• Network latency with bridge or hub
• Used with VLANs to tighten network security
• Workgroup servers should be ____
• Establishes a bandwidth domain also known as the
collision domain
Network Configuration
• Internetwork design seeks to provide _________.
• The star/extended star topology standard
• The data capacity of a link
• A list of equipment repairs
• Peer-to-peer network
Network Configuration
• Users in a peer-to-peer network
• First step in the troubleshooting process
• Loopback function on the NIC
• Negative influence on network performance
Novell IPX
• IPX network number
• Encapsulation for Novell version 3.12
• Novell routing protocol
• Novell RIP metrics
• Set the number of routes used for load sharing
• IPX routing command to show the number and type
of packets received and transmitted
• Command for the 802.2 frame format
• Part of the IPX packet that indicates the number of
routers through which the packet has passed
Switching
• Switch effect on bandwidth
• A switch segments a LAN into ____
• Types of frame forwarding
• Protocol to allow redundant paths in a
switched/bridged network
• Benefit of using VLANs
Switching
• Switch ports administratively assigned to a VLAN
• Switch ports automatically assigned to a VLAN
• Benefits of a switched LAN
• Requires more administration up front to setup the
database within the VLAN management software
