1) What are the advantages of using named ranges ?
You can insert or delete cells, rows and columns and the cell references remain intact.

2) How many named ranges should a workbook have ?
The more you have the more memory Excel needs to process the file.
10,000 or less would be recommended
20,000 would be excessive
40,000 would seriously impact performance
60,000+ would cause your file to crash

3) What is the difference between a Workbook Level named range and a Worksheet Level named range ?
Workbook Level - These can be referenced from any worksheet in the workbook, without prefixing.

=Name_Wbk 

Worksheet Level - These are intended to only be used on one specific worksheet although you can reference them from other worksheets by prefixing the name of the worksheet.

=Sheet1!MyWorksheetLevel 

4) What type of named range is created when you use the Name Box ?
Typing into the Name Box creates a named range with workbook level scope.
You can create worksheet level scope if you proceed it with the name of the worksheet and an exclamation mark.

5) What is a dynamic named range ?
A dynamic named range expands automatically when more data is added to the range.
This type of named range uses a combination of the worksheet functions OFFSET and COUNTA.

=OFFSET(Sheet1!$B$2,0,0,COUNTA(Sheet1!$B$1:$B$100),1)
