| T/F: ETHERNET CABLES AND SEGMENTS CAN SPAN ONLY A LIMITED PHYSICAL DISTANCE, BUT THERE DEVICES, SUCH AS REPEATERS AND HUBS THAT CAN BEE ADDED TO AN ETHERNET LAN TO EXTEND SEGMENTS. |

Term
| T/F: BRIDGES AND SWITCHES DIVIDE A LAN INTO MUTIPLE SEGMENTS. |

Definition
|
|
Term
| T/F: SWITCHES OPERATE AT MUCH HIGHER SPEEDS AND SUPPORT MORE ADVANCED FUNCTIONALITY, PERFORMING THREE MAJOR FUNCTIONS IN SEGMENTING AN ETHERNET NETWORK: FORWARDING FILTERING, AND FLOODING. |

Definition
|
|
Term
| T/R: THERE ARE A NUMBER OF WAYS IN WHICH THE PERFORMANCE BENEFITS OF A SWITCHED ETHERNET LANS CAN BE ENHANCED, INCLUDING MICRO-SEGMENTATION AND CONNECTIVITY HIERARCHIES; HOWEVER, THERE IS THE POTENTIAL FOR INTENTIONAL OR UNINTENTIONAL PHYSICAL LOOPS THAT CAN BE SOLVED BY STP. |

| WHAT 2 STATEMENTS ABOUT THE FUNCTIONS OF A HUB ARE ACCURATE? |
|
Definition
- A HUB EXTENDS AN ETHERNET LAN.
- A HUB IS A DATA LINK LAYER DEVICE.
|
|
|
Term
| WHICH 3 STATEMENTS BEST DESCRIBE COLLISIONS? |
|
Definition
- COLLISIONS OCCUR WHEN TWO OR MORE STATIONS ON A SHARED MEDIA TRANSMIT AT THE SAME TIME.
- IN A COLLISON, 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.
|
|
|
Term
| WHICH OF THESE CHOICES BEST DESCRIBES A COLLISION DOMAIN? |
|
Definition
| NETWORK SEGMENTS THAT SHARE THE SAME BANDWIDTH |
|
|
Term
| WHAT TYPE OF HARDWARE WILL HELP ELIMINATE COLLISIONS? |
|
Definition
|
|
Term
| WHAT 3 FACTORS ARE TYPICAL CAUSES OF NETWORK CONGESTION? |
|
Definition
| HIGH-BANDWIDTH APPLICATIONS, INCREASING VOLUME OF NETWORK TRAFFIC, MORE POWERFUL COMPUTER AND NETWORK TECHNOLOGIES |
|
|
Term
|
Definition
| IF THE SWITCH DOES NOT HAVE AN ENTRY FOR THE DESTINATION ADDRESS, IT WILL TRANSMIT THE FRAME OUT OF ALL PORTS EXCEPT THE PORT ON WHICH IT RECEIVED THE FRAME. |
|
|
Term
|
Definition
| IF THE SWITCH DETERMINES THAT THE DESTINATION MAC ADDRESS OF THE FRAME RESIDES ON THE SAME NETWORK SEGMENT AS THE SOURCE, IT DOES NOT FORWARD THE FRAME. |
|
|
Term
|
Definition
| IF THE SWITCH DETERMINES THAT THE DESTINATION MAC ADDRESS OF THE FRAME IS NOT FROM THE SAME NETWORK AS THE SOURCE, IT TRANSMITS THE FRAME TO THE APPROPRIATE SEGMENT. |
|
|
Term
| WHICH THREE CHARACTERISTICS APPLY TO A SWITCH? |
|
Definition
- USES A TABLE OF MAC ADDRESSES TO DETERMINE THE PORT TO WHICH THE DATA IS TO BE SENT.
- CONNECTS LAN SEGMENTS
- INCREASES THE NUMBER OF COLLISION DOMAINS
|
|
|
Term
| WHICH 3 FEATURES DIFFERENTIATE SWITCHES FROM BRIDGES? |
|
Definition
- LARGE FRAME BUFFERS
- SUPPORT FOR MIXED MEDIA RATES
- HIGH PORT DENSITIES
|
|
|
Term
| WHICH 3 STATEMENTS ARE ACCURATE ABOUT HOW THE NETWORK PEFORMANCE OF A SWITCH COMPARES TO THAT OF A BRIDGE? (SOLVING NETWORK CHALLENGES WITH SWITCHED LAN TECHNOLOGY) |
|
Definition
- SWITCHES OPERATE AT MUCH HIGHER SPEEDS THAN BRIDGES.
- SWITCHES SUPPORT MORE ADVANCED FUNCTIONALITY THAN BRIDGES.
- SWITCHES SUPPORT DEDICATED COMMUNICATION BETWEEN DEVICES.
|
|
|
Term
| WHICH 3 STATEMENTS ABOUT MICROSEGMENTATION ARE ACCURATE? |
|
Definition
- MICROSEGMENTATION INCREASES BANDWIDTH AVAILABILITY
- EACH DEVICE ON A NETWORK SEGMENT IS CONNECTED DIRECTLY TO A SWITCH PORT.
- MICROSEGMENTATION ELIMINATES COLLISONS.
|
|
|
Term
| DEFINE FULL-DUPLEX COMMUNICATION? |
|
Definition
- THE COMMUNICATION TYPE EFFECTIVELY DOUBLES THE AMOUNT OF BANDWIDTH BETWEEN THE DEVICES.
- THE NETWORK SENDS AND RECEIVES DATA FRAMES SIMULTANEOUSLY.
|
|
|
Term
| DEFINE HALF-DUPLEX COMMUNCATION? |
|
Definition
| THE NETWORK SENDS AND RECEIVES DATA FRAMES ONE AT A TIME, BUT NOT SIMULTANEOUSLY. |
|
