- 1What does a network switch use to direct traffic within a network? What must the switch do?MAC addresses
- first a switch must learn the MAC addresses of the devices connected - 2What is a MAC address?The hardware address of a device
- 3What are the transmission speeds of Switches?10Mbps
100Mbps
1Gbps
10Gbps - 4What transmission speed does fast ethernet run on? Gigabit ethernet?Fast ethernet: 100 Mbps
Gigabit Ethernet: 1Gbps - 5What do the color of the LED lights on a switch indicate?Yellow: connection is less than full speed
Green: connection is at full speed - 6The speed of any network is only as fast as the ...?slowest device connected
- 7What is an uplink port?a special port on a switch that connects one switch to another
- 8What are the two unique characteristics of uplink ports?- They are faster than other ports
- designed to handle both straight through and crossover cables - 9What kind of cables are normally used to connect switches together?crossover cables
- 10What is another name fro uplink ports?Medium Dependent Interface ports (MDI)
- 11What are the two kinds of switches?Managed and Unmanaged
- 12What is a managed switch?a switch that can be configured
- usually supports vlans - 13What is an unmanaged switch?AKA plug and play switch
- no configuration is needed - 14What is a trunk line in VLANs?the connection between a switch to the original switch in a VLAN setup
- 15What is a layer 2 switch?a switch that learns MAC addresses and and use it to send traffic to a device
- 16What is one thing a Layer 2 switches does not do?route traffic
- 17What is a layer 3 switch?- a router
- AKA multilayer switch
- uses ip address to route traffic between networks - 18What do switches use to learn MAC addresses of devices connected?MAC address tables
- 19What happens to MAC address tables entries if there is no traffic on the connection.they're erased
- 20What is one thing you can control on a managed switch?the number of MAC addresses each switch will memorize per switch port
- 21What is Redundancy?having multiple devices of the same setup so that if one device fails, the other can takeover
- 22What is a perk of Redundancy? What is load balancing?- Load balancing
- load balancing is having multiple devices share a workload so that overall performance can increase - 23What is backplane?The total throughput a switch is capable of at any given time
- 24How do you calculate backplane speed?multiply the number of ports, with the transmission speed
- 25What are the two main methods Switches use to send data?Store and forward
- 26What is the store-and-froward method for sending data?- older method
- a switch will receive an entire data frame, check for errors, then forward the frame
- - 27What is the store-and-froward method for sending data?newer method
- a switch needs to know the frame header that has the destination MAC address then sends the frame - 28Before switches were popular what were used?Hubs
- 29How do hubs work?took signals and sent them out to all the devices connected to it, leaving the devices to figure out who the data is for
- have no idea who's MAC Addresses
- they still are usefull as repeaters - 30What is one issue that can occur with switches?loops can occur
- physical: when a device is accidently pluged into itself
- not physical: recieving multiple copies of the same data fram - 31What protocol prevents loops from ocuring in switches?spanning tree protocol (STP)
- 32How does spanning tree protocol (STP) work?it uses a spanning tree algorithm known as STA, to search, find, then destroy redundant links
- the links are found by transmitting bridge protocol data units (BPDUs) - 33Routers can only transmit data as fast as the ....?media connected to it
- 34What is a directly connected route?a direct connection between two routers
- 35Is static routing commonly used?No, only in special scenarios
- 36What is the default protocol for default routing?TCPIP
- 37What are two other routing protocols?RIP
OSPF - 38What is RIP?Routing Information Protocol
- distance-vector protocol
- uses hop counts to determine the best route for data packets
- does not take speed into consideration - 39What is OSPF?Open Shortest Path First
- link-state protocol
- uses hops and speed to determine best route - 40What is the IP for the default route?0.0.0.0
- 41What does the metric column of a routing table indeicate.The quality of the route
- a lower number is a better route - 42What is the biggest concern with routing tables?their size
- if the table becomes to big it can affect the router - 43What do routing tables use for storage?RAM
- 44Which routing protocol uses little router memory?RIP
- 45Which routing protocol uses significant router memory?BGP
- 46What is convergance?a root bridge router that learns the entire network and then distributes that topology to the remaining routers on the network
