This is Module Review Number 2 from ICND PArt 1 Vol 1.
A hub extends an Ethernet LAN.
A hub reduces the size of a collision domain
Adding a hub eliminates the need for users on a network segment to compete for the same bandwidth.
A hub is a data link layer device.
A hub amplifies the data signal before retransmitting it.
Collisions occur when two or more stations on a shared media transmit at the same time
Larger segments are less likely to have collisions.
In a collision, the frames are destroyed, and each station in the segment begins a random timer that must be completed before attempting to retransmit the data.
Adding a hub to a network can improve collision issues.
More segments on a network mean greater potential for collisions.
Two or more devices trying to communicate at the same time
two networks that are connected
Network segments that share the same bandwidth
None of the above
Repeater
Bridge
Hub
Extender
high-bandwidth applications
many network segments
increasing volume of network traffic
More powerful computer and network technologies
greater distances for LANs
Bridges forward but do not filter data frames between LAN segments.
Bridges maintain MAC address tables.
Bridges are more "intelligent" than hubs.
Bridges can buffer and forward frames between two or more LAN segments.
Bridges operate at Layer 2 of the OSI model.
Isolating potential network problems to specific segments
Increasing the speed of a network
Extending a LAN to cover greater distances by joining multiple segments
Creating fewer collision domains
Forwarding data frames between LAN segments
Uses a table of MAC addresses to determine the port to which the data is to be sent
Connects LAN segments
Reduces the number of collision domains
Increases the number of collision domains
Filters data before forwarding it to its destination on the network
Large frame buffers
Use of a table of MAC addresses to determine the segment to which the data is to be sent
Support for mixed media rates
High port densities
Ability to segment LANs
Switches operate at much higher speeds than bridges.
Switches operate at lower speeds than bridges.
Switches support more advanced functionality than bridges.
Switches support less functionality than bridges.
Switches support dedicated communication between devices.
Implementing a bridge creates microsegmentation.
Microsegmentation increases bandwidth availability
Each device on a network segment is connected directly to a switch port.
Microsegmentation eliminates collisions.
Microsegmentation limits the number of segments on a network
