| A | B |
|---|
| Functionality | A network design goal that ask can a network meet the users requirements. |
| Scalability | A network design goal that states that the network must be able to grow. |
| Adaptability | A network design goal that states a network must look toward the future. |
| Manageability | A network design goal that ensures the stability of network operation. |
| Cut-Through - Fast Forward | switching mode - A MAC address of the destination device is read and the packet is Transmitted before the entire packet arrives at the switch - Latency is FIFO |
| Store & Forward | switching mode - The entire frame is received and checked before any forwarding takes place (Cyclic Redundancy Check - error checking). |
| Cut-Through - Fast Forward | switching mode - offers the lowest latency, immediately forwards a packet after receiving the destination address - Latency is FIFO |
| Fragment Free Switching | switching function - it examines the data packet size, doesn’t forward any packet below 64 bits - Latency is FIFO |
| Asymmetrical Switching | Provides switched connections between ports of unlike bandwidth, it has little congestion, but requires more bandwidth. |
| Symmetric Switching | Provides switched connections between ports of the same bandwidth, has increased throughput |
| Frame Filtering | A common technique for grouping users into distinct VLANs, this technique examines particular information about each frame. |
| Frame Tagging | A common technique for grouping users into distinct VLANs, this technique assigns a VLAN ID to each frame |
| Spanning Tree Protocol | Detects and breaks loops by placing some connections is a standby mode - these standby modes are made active in the event of a true Network failure |
| Blocking | A state of Spanning Tree Protocol - No frames forwarded, BPDUs heard |
| Listening | A state of Spanning Tree Protocol - No frames forwarded, listening for frames |
| Learning | A state of Spanning Tree Protocol - No frames forwarded, learning address |
| Forwarding | A state of Spanning Tree Protocol - Frames forwarded, learning address. |
| Disabling | A state of Spanning Tree Protocol - No frames forwarded, No BPDUs heard |
| Bridge Protocol Data Units | STP packet sent out to exchange information among bridges in the network. |
| NIC | This is one thing that can be changed when migrating from 10MB to 100 MB bandwidth over Cat 5. |
| Content Addressable Memory | This is where learned address are stored in a switch when they are learned dynamically. |
| Default Route | Route defined by a network administrator on where to send packets if no table entry is found. |
| Distance Vector Routing | This has scheduled updates (IGRP & RIP) gets all topological data from Neighbors and adds to the metric value of a packet as it receives information. |
| Link State Routing | 24. Updates are sent when network changes occur, a router can calculate its own shortest path to its destination “know all the links of the network and picks the shortest path” OSPF |
| Multi-protocol Routing | When a router is able to support more than one independent routing protocol at a time (IGRP & RIP). |
| Routing Protocol | Protocols between networks (IGRP, OSPF, EIGRP, RIP, EGP, BGP) |
| Routed Protocol | Protocols over a network (node to node) (TCP.IP, IPX, AppleTalk) |
| timers basic | Command that lets you control how often IGRP sends updates |
| no metric holddown | Command that disables holddowns, accepts a new route, meaning that after a route has been removed, a new one is accepted immediately. |
| 30 Seconds | Default RIP updates |
| 60 Seconds | Default Novel RIP updates |
| 90 Seconds | Default IGRP updates |
| Ethernet 802.3 | Novel Encapsulation name for novell-ether, or NetWare Version 3.11. |
| Ethernet 802.2 | Novel Encapsulation name for sap, or NetWare Version 3.12 |
| Ethernet II | Novel Encapsulation name for arpa, this is used with TCP/IP |
| Ethernet - SNAP | Novel Encapsulation name for snap. |
| Standard Access List | This access list blocks all traffic from a network, it allows all traffic from a network, or deny protocols suites, it checks only the source, this ACL gets put close to the destination, its number ranges are from 1- 99. |
| Extended Access List | This access list can allow some users to access FTP but allow all users to access the web, they check both source and destination packet address, this ACL gets put close to the source, its number ranges are from 100 - 199. |
| DNS | Port # 53 |
| Dynamic | Term used when switch ports are automatically assigned to a VLAN |
| FTP | Port # 21 |
| IPX addressing | Total of 80 bit hex # - 32 bits Network # - 48 bits MAC |
| IP addressing | Total of 32 bits, 4 octets |
| debug ipx routing activity | Command checks ipx routing tables. |
| show ipx traffic | Command shows the number & type of packets received and transmitted by the router. |
| checks ipx sap activity | Command checks IPX SAP updates. |
| ipx maximum-paths | Command is designed to increase throughput by allowing the router to choose among several equal-cost, parallel paths. When paths have differing costs, the router chooses lower cost routes before higher-cost routes. |
| Service Advertising Protocol | 48. Server advertises its network services and addresses 60 second update. |
| Get nearest Server | Broadcasts from a client needing a server to log onto. Server responds with this response - if no server or router responds NetWare Client/ Server interaction begins when the client starts up. |
| host | Command is used instead of writing a wild card of mask of all 0 |
| any | Command used to access all of something |
| log | tells the server if an address was denied, the time and the IP address of it. |
| Application Layer | provides services to the application process, such as electronic mail, file transfer, and terminal emulation. |
| Presentation layer | ensures that information sent by the application layer of one system will be readable by the application layer of another |
| Session Layer | establishes, manages, and terminates sessions between |
| Transport Layer | is responsible for reliable network communication between end nodes; layer provides mechanisms for the establishment, maintenance, and termination of virtual circuits, transport fault detection and recovery, and information flow control. |
| Network Layer | layer provides connectivity and path selection between two end systems |
| Data Link Layer | provides reliable transit of data across a physical link |
| Physical Layer | defines the electrical, mechanical, procedural and functional specifications for activating, maintaining, and deactivating the physical link between end systems |
