Track contact Sitecore goal execution

How can we track a contact has executed a specific goal or not ? To track goal execution we have GetKeyBehaviorCache() method.

Guid goalReadId = new Guid("Goal GUID");
Sitecore.Analytics.Tracking.KeyBehaviorCache cacheGoal = Sitecore.Analytics.Tracker.Current.Contact.GetKeyBehaviorCache();
bool goalBlogTriggered = cacheGoal.Goals.Any(G => G.Id == goalReadId);
