【Soulguard】 only prevents the card from leaving the field, not from being destroyed. So in case of 【Soulguard】, there will be damage from 【Penetrate】, but in case of "Dragobond", there will be no damage from 【Penetrate】 from the first attack because "Dragobond" allows the chosen monster to be "not destroyed".
