The most common set of responses to a strong 2♣ opening are as follows:

If... then ...
I have 8+ HCP with a balanced hand Respond 2NT. If opener rebids notrump, it is quantitative.
I have 8+ HCP with a good 5+-card major suit (at least 2 of 3 top honors) Bid your suit at the 2 level. If partner raises your suit, follow up with a control bid or 4NT, Blackwood.
I have 8+ HCP with a good 5+-card minor suit Bid your suit at the 3 level. If partner raises your suit, follow up with a control bid or 4NT, Blackwood.
Otherwise Bid 2♦ (see below).

The 2♥, 2♠, 2NT, 3♣, and 3♦ responses are said to be "positive", since they show the presence of some quality of responder's hand. The 2♦ response is "waiting", an artificial relay that denies the positive responses and asks opener to describe their hand. Thus, 2♦ is like a "catch-all" response, used for the following kinds of hands:

• Less than 8 HCP, for example ♠J872 ♥643 ♦J2 ♣KT97
• Unbalanced with a low-quality suit, for example ♠KT985 ♥A63 ♦5 ♣Q765
• 4441 distribution regardless of strength, for example ♠KQT2 ♥4 ♦K754 ♣AJ93.
