| Sorry, but your analysis is flawed. Reread the question and understand MS
objectives. The only answers that would be 'MS kosher' are B & E. Ideally it
would be "try B then if B is false, do E", but you have to select all that
apply. B & E will satisfy the conditions presented in the question and will
cover any possible router functionality.
Whether or not you had too much to drink, I don't know, but either way, your
answer is wrong.

| Whilst I am ready to admit that the 'MCSE correct' answer is 'B and E', I
maintain that the question is fundamentally flawed and A,C and E is better
as it more accurately describes the implementation and provides for fault
tolerance.
Anyway, B and E are mutually exclusive.

If B is true, then E is superfluous. If E is true, then B is superfluous.
So you can't choose them both at the same time.
Anyone from MS or Sybex reading this ?

| Ok, lets review the answers:
What should you ensure before you start implementing your plan? (Choose all
that
apply.)
A. Make sure that you have identified a Windows 2000 Server on each
subnet on which to install the DHCP services.
WRONG - Not a necessity here. One DHCP server can accommodate the needs of
multiple subnets. Sure it adds fault tolerance, but the question did not
require fault tolerance. Read the question carefully.
B. Make sure that your router supports BootP.
CORRECT - This is a logical first step when using DHCP services over
multiple subnets. If the router supports BootP message passing, then no
configuration of DHCP relay agents is needed.
C. If your router supports BootP, make sure that you install a DHCP
server on each subnet.
WRONG - If your router supports BootP, then there is no need to have a DHCP
server on each subnet. Or vice versa - if you have DHCP servers on each
subnet, there is no need to pass BootP messages via the router.
D. If your router supports BootP, make sure that you install a DHCP
relay agent on each subnet.
WRONG - If your router supports BootP, there is no need to install a DHCP
relay agent. They both do the same job!
E. If your router does not support BootP, make sure that you install a
DHCP relay agent on each subnet.
CORRECT - this goes hand in hand with step B. You need to verify if your
router supports BootP *and then* if it does not, install a DHCP relay agent
on each subnet that does not have a DHCP server on that subnet.
Answer A *could* be correct if fault tolerance was the directive in the
question, but it was not. Answers C and D are just plain wrong. I would
advise re-reading the chapter on DHCP implementation across subnets in your
reference book.
Reading and understanding questions like these is a vital learning step to
being a good troubleshooter. You need to be sure that you are attacking the
problem and only the problem. In some cases overkill can be detrimental, so
make sure that you solve the issue, but don't create new ones.
Good luck on your study and certification efforts.

I already have 216. I also run our DHCP services.

None of the other options mention installing an *actual* DHCP server
(admittedly loosely read here as "DHCP services").
And if you are to satisfy the requirement for minimising both broadcast
traffic and traffic crossing the router, you would consider as a starting
point having one DHCP server per subnet. You may then go ahead and discount
this for other valid reasons.
Fault tolerance should be an implicit criteria for all scenarios in 216
unless the question specifically tells you otherwise.

But what if it doesn't ? Are you going to throw the router away ? This is
financially incorrect, again an implicit criteria for answering all
questions on 216. And even if it does support BootP, your aim to should be
to reduce traffic across the router.

Technically there is no need. But if the router supports BootP, then this
means that DHCP servers on subnets on different sides of the router can be
configured with multiple scopes to provide fault tolerance. If the router
is not BootP compliant, then you would provide for fault tolerance with
multiple DHCP servers on the same subnet serving *the same scope* - not a
pretty configuration to deal with.

If you *only* install a DHCP relay agent, you aren't meeting the requirement
for reducing traffic across the router.

Fault tolerance is implicit.

Absolutely not ! First of all, experience. Secondly, a *thorough*
understanding of why things work the way they do. Thirdly, common sense
(bump).
What happens in the real world if you have a problem that isn't 'in the box'
? Or slightly outside the test criteria for the MCSE ?

|
| If you have these big issues with MCSE tests, why are you concerned with
taking them? Everyone knows the answers need to be MS answers. Either get
with the program and learn the MS answers, don't get with the program and go
about your business, or send your complaint to Microsoft. Arguing over what
SHOULD BE the right answers here is pointless.

| Congrats on your certification success, but it looks like you kinda missed
the point of analysis of the business case. Fault tolerance is not always
implicit, in many cases cost is the overriding factor. As far as B is
concerned, this is merely part of the answer. B in conjunction with E is the
best solution. Of course you don't throw out the router if it fails test B,
but if it does you need a backup - answer E.
And really, how much traffic does DHCP generate on the network? Unless you
have your lease set to some unreasonably small period, the traffic should be
minimal. And finally, yes, understanding the whole problem before digging in
*is* a vital tool for the successful troubleshooter. Any troubleshooter that
runs in half-cocked not understanding the whole scope of the problem is
unlikely to solve it correctly.
I am done debating this issue as you apparently have yourself firmly
convinced in your methodology.

| Thanks for that, I was feeling a bit battered.
I passed 216 (not with the highest of scores... but then they just ditched
score reports :-)
I remember being told off badly in class for questioning a blatant error in
one of the books -"don't go confusing the other students".
How useful is that ?
Just trotting out the line - "it says so in the book so it must be
correct" - sounds too similar to "it says so in the braindump so it must be
correct".
Top marks to Microsoft for decertifying people who breach copyright and for
their efforts to make the MCSE content reflect real world practice.
I just wish they would use written, essay style questions and
practicals..... that would really sort us out.
As for what I am doing here..... after seven years working in Technical
Infrastructure and Network Administration, my employer 'allocated' me to get
certified as part of our Gold Partner Status.

| You`re just showing your ignorance
A is definately completly wrong
B is 100% correct
C is !00% incorrect
D is 100% incorect
E is 100% correct
even for fault tolerence 2 dhcp servers would be used.I have a cable
modem my address is isued by a central dhcp server.This dhcp server is
probally giving addresses for 200+ different subnets.There is no way
the cable company have 1 dhcp server per subnet(200+dhcp servers),for
fault tolerence they are probally using 2 dhcp servers.It just shows
how rubbish the MCSE certificate is if A MCSE can`t even understand
such a *simple* question

I know the answer which gets you the marks is 'B and E' - just because it
does. No other reason. So if you want the marks, choose it. But it says
very little about the candidate's understanding of or ability to use DHCP.
About your cable modem scenario - well, actually, the question says this :
"You are the administrator of a network in a *single* location that has
grown dramatically. "
Where's the cable modem ?
Is anyone surprised that this group is full of pictures of racing cars and
rude words when the quality of relevant discussion is so low and people are
so ready to insult ?

- You have a router that you want to use to break the network into three
subnets in order to control the bandwidth utilization of the overall
network.
Does this mean REDUCE traffic across the router? Or does this mean control
the bandwidth on your network as in isolate boxes that'll slow down
performance for other users.
My opinion is, your reading into the question too much.

it`s not just the answers that gets you the marks but it is also how
it is in the real world.This questions says a lot about the
candidate's understanding of or ability to use DHCP,if they dont know
b,e are *totally* correct they don`t know shit

I gave you this scenario to try to make you understand how ridiculious
answer A is.If answer A is correct that means if the network grew
again to 50 subnets you would also increase dhcp servers to 50 which
in the real world is totally wrong also the question says "you are
going to implement DHCP to manager the IP addresses centrally."which
certainly does`nt mean 1 dhcp server per subnet

| Time to revisit this.
The scenario given in the question is typical of network growth in small /
medium enterprises (SMEs).
What happens is that fixed address management becomes a burden necessitating
the switch to DHCP. At the same time, the network may be broken up into
multiple subnets in order to reduce network traffic and increase
performance, siting relevant servers and clients together.
Now - the move would be from static IP addresses to dynamically allocated
addresses and from one subnet to *TWO* or *THREE* subnets. No-one is going
to jump to from static to dynamic and one subnet to twenty or a hundred
subnets at the same time.
So, given the move to two or possibly three subnets, I stand by A,C and E.
One DHCP server per subnet for fault tolerance configured with mulitple
scopes split 80/20.
No-one is talking about an enterprise with 20,000 computers on it connected
to a WAN across thirteen countries.....

| You`re method would work but why use 3 dhcp servers when you can just
as easily use 1 or 2?
A important part of setting up a network infrastucture is reducing
cost of ownership
You`re method does`nt reduce the cost of ownership so it is *wrong*

| Your answer is B & E.
B: your Router needs to support BootP to subnet
E: if your Router DOESN'T support BootpP, you need to install a
Relay Agent.
Try reading Windows Help files for info on BootP
If your router doesnt support BootP you need a Relay Agent
