70-467 Question #156: Real Exam Question with Answer & Explanation

The correct answer is B: Upgrade the four package versions. Use an XML editing tool to merge the compatible. SSIS packages are XML files, so merging four SSIS 2005 versions requires upgrading them to SSIS 2012 format first to ensure schema compatibility before using an XML editor to combine the changes.

Question

The IT department is currently upgrading all SQL Server Integration Services (SSIS) packages to SSIS 2012. The final version of a complex SSIS 2005 package has been overwritten. Four prior versions of the package exist. Each of the prior versions contains a different part of the final solution. You have backups of all associated project files. You need to create an updated package as quickly and accurately as possible. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

Options

  • AUse an XML editing tool to merge the compatible changes of the package versions by
  • BUpgrade the four package versions. Use an XML editing tool to merge the compatible
  • CUse the DataSet.Merge method to merge the compatible changes of the package versions
  • DUpgrade the four package versions. Use SSIS Designer to visually compare the package

Explanation

SSIS packages are XML files, so merging four SSIS 2005 versions requires upgrading them to SSIS 2012 format first to ensure schema compatibility before using an XML editor to combine the changes.

Common mistakes.

  • A. Merging SSIS 2005 packages with an XML editor before upgrading risks silent data loss or errors because the SSIS 2005 and SSIS 2012 XML schemas differ and are not directly compatible.
  • C. DataSet.Merge is an ADO.NET in-memory method for combining DataSet objects and has no ability to parse or merge SSIS package XML files.
  • D. SSIS Designer has no built-in visual diff or merge capability, making it impractical and error-prone for reconciling four separate package versions accurately.

Concept tested. SSIS package upgrade and XML-based version merging
