If you use a gumpaste cutter that's that shape and press it into the fondant to imprint the shape you can do it. Just do one line at a time and line up the cutter to meet at the top and bottom when you do the next line up. You can do the same thing with round cutters, flower cutters, whatever you want.
AYes, but the pattern on the cake above is more of an oval shape-it looks like there's impressions done between where the Dragees are placed you can add that effect with an impression tool (hope I haven't confused you)!
There are stacked impression tools/cutters that make this pattern but they are basically cutters attached to each other as CC stated. If you want that exact pattern without buying an extra tool I'd just squish a metal, round cutter and gently make your impressions.
