Threaded View
I was checking a testking document and it seams that some answers they
are not correct.

Please advise if these documents have any interest or Iím just wasting
my time.

Here goes just one of the questions:

Why is D wrong?


QUESTION NO: 11
With regard to bridges and switches, which of the following statements
are true? (Choose
three.)
A. Switches are primarily software based while bridges are hardware based.
B. Both bridges and switches forward Layer 2 broadcasts.
C. Bridges are frequently faster than switches.
D. Switches typically have a higher number of ports than bridges.
E. Bridges define broadcast domain while switches define collision domains.

F.
Both bridges and switches make forwarding decisions based on Layer 2
addresses.
Answer: B, E, F
Explanation:
B, F: Both are layer 2 (data link) devices designed to forward layer 2
broadcasts and multicast
addresses.
E: All hosts within a bridged network comprise a single broadcast
domain, while switches can be
used to segment LANs into separate collision domains. Switches are
VLANcapable
while
bridges are typically not capable of this.

Thanks for your time,

Cheers joe

Re: Testking feedback.
Testking (and for that matter, most of the "braindump" sheets I've
seen) are full of errors. If they are your only way of studying, it
will quickly show up in the real world. Don't trust them, and don't
assume that just because the Braindump says as answer is correct that
it actually is.

For your q:

A) False. Switches also use dedicated ASICs and hardware for forwarding
B) True.
C) False. Both bridges and switches can work at wire speed.
D) True. A bridge joins two ethernet segments. A switch is a multiport
bridge.
E) False. Routers "define" broadcast domains. Both bridges and switches
define collision domains.
F) True. Whether a bridge passes a packet or not depends on its MAC. A
switch forwards according the MAC table.

So B,D,F are true.


Re: Testking feedback.
Cross check all your testking or "braindump" answers.  The questions
are good, and they are the type you will see on the exam, but there are
many, many wrong answers (and explanations for that matter).

Thanks guys

Re: Testking feedback.
I woud say

D is correct and E is false

Not all switces are Vlan Aware bij default
