I disagree, I like a qualified answer. I often have other options and this allows me to use them. "Can you do X?" "Maybe, I'm very busy so I might not get to it this week" "Ok nevermind I'll ask [other team member] / I'll do it / I'll do Y instead" If you say no when you're busy/uncertain, you quickly become useless to me and I'll learn not to ask you for things. But if you say yes, I'm counting on you and I will be both disappointed and in trouble if you don't deliver.
