QUESTION 1:
Both switches and hubs are being utilized within the work. Which of
the following is true regarding the use of switches and hubs work connectivity
in work?
A. Switches take less time to process frames than hubs take
B. Hubs can filter frames
C. Switches do not forward broadcasts
D. Switches increase the number of collision domains in work
E. Using hubs can increase the amount of bandwidth available to hosts
F. None of the above
Answer: D
Explanation:
The biggest benefit of using switches instead of hubs in your work is that each
switch port is actually its own collision domain. (Conversely, a hub creates one large
collision domain.) But even armed with a switch, you still can't break up broadcast
domains. Neither switches nor bridges will do that. They'll typically simply forward all
broadcasts instead. Switch creates the collision domain per port, so we can say switch
increase the number of collision domains.
QUESTION 2:
Which one of the following characteristics is true regarding the use of hubs and
switches?
A. Hubs can have their ports be configured with VLANs
B. Using hubs is costly with regard to bandwidth availability.
C. Switches can not forward broadcasts.
D. Switches are more efficient than hubs in processing frames.
E. Switches increase the number of collision domains in work.
Answer: E
Explanation: Switches increases the number of collisions domains in work.
Switches that are configured with VLANs will reduce the size of the collision
domains by increasing the number of collision domains in work, but making
them smaller than that of one big, work.
Incorrect Answers:
A. Switches are capable of VLAN configurations, but hubs are not.
