Looks like a detailed breakdown of this one is in order:
VLANs have been designed to _____.
A. address forwarding decisions based on transport layer information and
spanning tree scalability
(VLANs have nothing to do with Layer 4, so we can cross this one out.)
B. maximize the amount of traffic switched at Layer 3 and minimize the
amount of traffic switched at Layer 2
(Design dictates that we want to take the opposite approach, and besides -
VLANs are Layer 2 services, not Layer 3.)
C. address the scalability issues of a flat network topology and the
addition of network management through Layer 3 routing protocols
(Well, I like the use of the words "scalability" and "flat," but VLANs have
nothing to do with routing protocols, and routing protocols don't have
anything to do with network management!)
D. address redundant access to the workgroup and migration of servers to
server farms for increased security and management of data resources
(Hmmmm...redundancy? Not sure that's the thrust behind using VLANs...I like
the security idea, but think design again - that's a Distribution Layer
problem, not an Access Layer problem, which is where VLANs live. Scratch
this one too.)
E. address segmenting broadcast domains while still providing network-wide
shared services and allowing users to use hyperlinks to hop transparently
between servers across enterprise networks
(Okay, segmenting broadcast domains I love...but *hyperlinks*? Your signal
is breaking up, Captain...)
Every answer given is a tug-o-war in itself - it gives enough "correctness"
to make you want to pick it, but then throws a bunch of crap at you from
left field. So, the verdict is: this has to be one of the most
poorly-worded quiz questions *ever* written. Ignore it. :-)
