Brazil showed they remain the team to beat at these World Cup finals after defeating the Ivory Coast thanks to a Luis Fabiano brace and a third goal from Elano.
Their evening ended on a disappointing note when Kaka was sent off in the closing stages after lashing out at Kader Keita in an ill-tempered conclusion to the match.
The five-times World Cup winners only showed their true quality in brief glimpses but they had far too much for the Elephants, who produced another dire performance following their grim goalless draw with Portugal five days earlier.
Dunga opted to start with an unchanged starting line-up while Sven-Goran Eriksson brought in Didier Drogba only for the Chelsea striker to produce a poor display despite scoring a late consolation goal.
Brazil took the lead after 25 minutes. The ball broke on the edge of the area to Luis Fabiano who strode forward before lashing a shot high into the net from a difficult angle.
Emmanuel Eboue lashed a shot wide just before the half-time whistle, but that was as good as it got for the Elephants in the opening 45 minutes.
The match was as good as over five minutes into the second period when Luis Fabiano added a second goal.
This time the Sevilla forward steered the ball home, although there was a clear handball in the build-up. Boubacar Barry got a hand to the shot but couldn't keep it out.
Aruna Dindane picked out Drogba at the far post after 52 minutes but the striker could only guide his header wide of the target.
Ten minutes later one of the best moves of the match ended with Barry parrying Kaka's shot. Almost immediately afterwards Kaka beat his man, got to the byline and pulled the ball pack for Elano to sidefoot his shot into the net with Barry helpless.
The former Manchester City midfielder soon had to be carried off the pitch with a leg injury and, as Ivory Coast finally broke free from their shackles, Drogba timed a run to perfection with 11 minutes left as he sent his header past Julio Cesar.
The final 10 minutes were fractious and Kaka was booked late on for an off-the-ball incident before being dismissed after clashing with Keita.
Keita walked into Kaka and went down clutching his face. The incident left a nasty taste in the mouth.
