|
non-deterministic
less overhead collisions exist |
|
|
What is true concerning physical and logical topologies?
|
Logical topologies consist of virtual connections between nodes.
|
|
|
What determines the method of media access control? (Choose two.)

|
What is true regarding media access control? (Choose three.)
|
Ethernet utilizes CSMA/CD
defined as placement of data frames on the media Data Link layer protocols define the rules for access to different media |
|
|
Which statements describe the logical token-passing topology? (Choose two.)
|
Computers are allowed to transmit data only when they possess a token.
Electronic tokens are passed sequentially to each other. |

|
What two facts are true when a device is moved from one network or subnet to another? (Choose two.)
|
The device will still operate at the same Layer 2 address.
The Layer 3 address must be reassigned to allow communications to the new network. |
|
