70-642 考試是 Microsoft 公司的 TS: Windows Server 2008 Network Infrastructure, Configuring 認證考試官方代號，Microsoft 認證可代表豐富且多樣化的工作角色及責任。因此，取得特定的認證將可做為具備成功執行重要 IT 功能所需之能力的最佳證明。由於受到全世界企業專家的熱烈支持，Microsoft 認證仍是達到長期事業目標的最有效率的方法之一，並且是公司用來開發及留住重要 IT 人員的不二法門。

MCTS認證翻譯過來就是微軟認證技術專家，是微軟認證體系中最基礎的證書，其證書的等級相當於以前的MCP認證，並做為MCP認證的後繼證書，持有MCTS代表對微軟某個技術或某個產品具有充分的技術能力，可以執行搭建和管理(針對網管或系統管理人員) 或程式撰寫能力(針對開發人員)。
　　但MCTS認證更有針對性的在每個證書多了其技術方向的說明，MCTS認證據IT認證考試資源網介紹MCTS認證側重于某項的微軟產品或技術的資格的鑒定，MCTS認證是以產品和技術為認證的標的，與前一代的MCP認證不同，每一個MCTS認證均只有一科考試科目，只要通過該科考試，即可取得MCTS資格，但開發技術的MCTS要求考生必須要先通過70-536:TS: Microsoft .NET Framework Application Development Foundation，才可以擁有以通過一科考試的方式取得開發技術的MCTS認證的資格。
