Very stumped on these 5 practice questions

I've been studying CCDA for quite a while and can find no concrete verifications to these 5 questions. Can anyone else lend their expertise as to what's right or wrong?

1) A very large organization has received its IPv6 address range from their ISP and intends to use only IPv6 addresses internally. They will access the Internet through port address translation (PAT). What is a requirement for their Domain Name Servers (DNS)?

A) They no longer need DNS servers.
B) Their DNS servers need to support both IPv4 & IPv6 addresses
C) Their DNS servers need to support only IPv6 addresses
D) Their DNS servers need to support only IPv4 addresses
E) They need additional DNS servers in their network just for IPv6 addresses
F) There are no changes required to their DNS servers

Boson says the answer is B

2) What is the first task that a network designer should perform when documenting the customer requirements and existing environment of a network design project?

A) Assess the scope of the design project
B) Identify applications, both planned and installed
C) Identify the customer’s business constraints
D) Identify the customer’s business goals

Boson says D, the DCN book says C

3) The routers on a network are being documented for a technical report. Choose the items that should be included in his report (Choose 3)

A) Interface error statistics
B) Router software revision
C) Router power requirements
D) Interface loads
E) Interface configurations

Boson says A, B, E

4) A prototype network is used to test a proposed network redesign solution. Although the test seemed to be successful, network performance is unacceptable when implemented in the live network. What was wrong with the prototype network test?

A) The prototype should have been built on the live network.
B) The prototype failed to test for the proper characteristics
C) The prototype network didn’t match the live network exactly
D) Different configuration parameters existed in the prototype network.

Boson says B, I say A

Thanks for your help

Oops, sorry here's the fifth.

5) Which two are the primary sources for documenting a customer’s requirements for a network design project?

A) network application specifications
B) request for proposal (RFP)
C) diagram of desired network
D) network performance specifications
E) interview with customer

Boson says D & E, I say B & E

The following is worth what you paid for it, money back guarantee.

1) I agree with B, it seems that they will be running a mixture of 6 (internal) and 4 (external) from the statement, so why wouldn't they need DNS to support both? As I understand it, the first request for a host name mapping, will go to a local DNS server, that server will then interact with the outside servers to get the address. Since those will be vers 4, the internal server needs to talk both, I think.

2) all the books I've studied, seem to indicate D would be correct. 1st the goals, then the constraints.

3) that one confuses me too, because I'd want to pick A, B, D and E! I mean the books clearly point out getting interface utilizations, e.g., Diane Teare 640-861 book, chapter 2, page 70.

4) No comment, the books all seem to explain the use of pilot versus prototype differently. I'm confused.

5) I'm guessing the "trick" is, there is not always an RFP. But an RFP would have network performance specs in it, and that is something you need to know, so D is "more right" perhaps.

Thanks for the insight!! Anyone else care to take a stab at these? Whether you're looking at it from a technical standpoint or Cisco's standpoint, the questions could be answered either one way or another.

Regarding 4, I would say that if the prototype tested for the right characteristics then the live network should perform in an acceptable manner.
