Question 5
Question
Which of the following is true about the CSMA/CD algorithm?
Answer
-
The algorithm never allows collisions to occur
-
Collisions can happen, but the algorithm defines how the computers should notice a collision and how to recover
-

-
None of the other answers is correct
Question 6
Question
Which of the following is a collision domain?
Answer
-
All devices connected to an Ethernet hub
-
All devices connected to an Ethernet switch
-
Two PCs, with one cabled to a router Ethernet port with a crossover cable and the other PC cabled to another router Ethernet port with a crossover cable
-
None of the other answers is correct
Question 7
Question
Which of the following describe a shortcoming of using hubs that is improved by instead using switches? (Choose two answers.)
Answer
-
Hubs create a single electrical bus to which all devices connect, causing the devices to share the bandwidth
-
Hubs limit the maximum cable length of individual cables (relative to switches)
-
Hubs allow collisions to occur when two attached devices send data at the same time
-
Hubs restrict the number of physical ports to at most eight

-
Each manufacturer puts a unique code into the first 3 bytes of the address
-
Each manufacturer puts a unique code into the first half of the address
-
The part of the address that holds this manufacturer’s code is called the MAC
-
The part of the address that holds this manufacturer’s code is called the OUI
