A Correct answer
Explanation

For seven different applications, the number of unique custom connections is calculated as n(n-1)/2 = 7×6/2 = 21. This represents all possible pairs of applications that could be connected. Each connection is bidirectional but counted once, making this the complete set of integration points.

AI explanation

For n distinct systems to be connected pairwise via custom (point-to-point) connections, the number of unique connections is C(n,2) = n(n-1)/2. For n=7 applications, that's 7×6/2 = 21. This is exactly the number given in the statement, so the statement is mathematically True. This combinatorial fact is the classic argument for why point-to-point integration doesn't scale (connections grow quadratically) compared to a hub/ESB pattern, which needs only n connections. There's no standard alternate reading of 'custom connections' that would change this count for 7 systems, so the statement should be marked True, not False.
