私が見ていたのは http://www.mongodb.org/display/DOCS/Quickstart+Windows を見て、その指示に従いました。 どなたか、MongoDBを実行する際の問題点を教えていただけませんか（Windows 7を使用しています）。

どのように解決するのですか？

ログ出力に明記されていますね。

exception in initAndListen: 10296 dbpath (/data/db) does not exist, terminating

このディレクトリを単純に作成するか、より良い方法は で定義します。 を設定ファイル内の設定値として定義し、それを mongod -f C:\path\to\your\mongodb.conf .
