Hi all,
I've got these three questions and I'm truelly not sure about the answers so what do u think ?

1.You want to pass object data from a component that resides on a client computer to a component that resides on a server. You want to keep network traffic to a minimum. Which three methods can you use to accomplish this? (Choose three)

A. Pass the data in a variant array.
B. Pass the data as a string buffer.
C. Pass the data as a disconnected ADO recordset.
D. Set each property of the server object to be equal to the equivalent property of the client object.
E. Write the data to the database. Then access the data from the server component.

2. The address table in a database contains the following columns.

AddresslD
StreetNumber
StreetName
City
Country
CreatedBy
CreatedDate
Timestamp

Which three columns would most likely be properties of an address business object? (Choose three.)

3. You want to use data environment designer to place controls and labels on a form. The controls and labels will be bound to the result set of a stored procedure that already exists in the database. Which two steps must you take to accomplish this (choose two)

A. Add a connection to the data environment

B. Add a command to the data environment that references the stored procedure. Then drag the command from the data environment to the form

C. Create a new stored procedure by using the database designer. Then drag the stored procedure from the data environment to the form

D. Map each field of the result set to a specific type of control by using the field mapping tab of the options dialog box for the command.

I'm really confused about their answers so plz I really need someone to help me with them

yours,
tamer

I would say:

1. A,B,D This is really a process of elimination. The database commands would both be slow. I'm not sure that the string buffer is a good idea but it should work quickly.

2. StreetNumber, StreetName and City. I would have chosen Country as well but the question only asked for three. The other four would be used internally and not made properties of the object in most cases.

3. A,B. The Data Environment Designer lets you do this through drag and drop once you have a command object. C would have to be done by accessing the database. D is bogus and mentions "to a specific type of control" which would not help.

Those are braindump questions. I recognise one of them from one of my exams. Oh well. I'm sort of beyond caring. A guy in the jobs forum was saying how his MS certs were not only useless but worse than useless! That had me chuckle.

...

I wouldn't do D. It's n network calls (n = no. of properties) !!
C is a bit bizarre, but it should work.
