I am pretty new to graphic design world & obviously Inkscape too. I just need to draw a simple circle with dots in Inkscape. I have tried all the options in the stroke style section, but wasn't successful. I have searched online about this, but found only a workable solution here. But I think that is complicated solution to do just this simple job. Is there any other easier way to draw a simple circle with dots? I really hope there is something.

Thanks in advance.

You could use a pattern along a path effect.

Here's an example. The pattern itself was simply a small circle (shown top left), which was copied to the clip board, then applied as a pattern to a larger circle:

I agree that the link you've provided uses an unnecessarily complex method. The project you seek is called polar array in some CAD software. Using "inkscape polar array" provided many results, one of which is the SEGD resource:

How to create these rotated clones?

In the linked answer, the responder used large circles as his object, but you can use anything created in Inkscape. It's an easy matter to resize his hula hoops to dots.

The image above is from the linked answer.

More options:

• use a stroke with a dot pattern (requires the correct ratio between the dash length and the stroke width, and also requires rounded caps): https://codepen.io/manabox/pen/wlLrh
  


• use the polar arrangement option of the Object > Arrange dialog: http://www.inkscapeforum.com/viewtopic.php?t=31762
  

I will propose another solution.

1. 
   

   You can start with a circle and add a marker to the stroke.

   
   
   

   

   
   



2. Convert to stroke. Path→Object to Path or Shift+Ctrl+C`.




3. Select all the nodes on the stroke and add new nodes with: Insert new nodes into selected segments. Do this until you have the number of points that you want.




4. Convert stroke to path. Path→Stroke to path or Ctrl+Alt+C`.




5. Ungroup and delete the line.
