See the diagram attached herewith.

What would the mulmeter shows if I connect a multimeter accross
A & B in resistance mode ?

DFR-Diode Forward Resistane
DRR- Diode Reverse Resitance

Both are identical diodes and the multimeter is set in auto range.

Practically, it will be near infinity in both cases.
 

It will show infinity most probably (while you don't touch the multimeter terminals)....
 

A 1N4148 diode is in a clear glass case. When the meter reverse-biases it then light on it will cause it to pass a small current.
