1Z0-060 Question #187: Real Exam Question with Answer & Explanation

Question

Options

• Aalphanumeric columns that will have invalid binary representation after converting to the chosen
• Balphanumeric columns that need conversion to a different binary representation before
• Cdate columns that will have invalid binary representation after converting to the chosen Unicode
• Dnumeric columns that will have invalid binary representation after converting to the chosen
• Enumeric columns that will exceed the column size limit after converting to the chosen Unicode
• Falphanumeric columns that need no conversion

Explanation

The DMU classifies columns into categories based on how their data is affected by Unicode conversion, including invalid binary representation across multiple column types.

Common mistakes.

• B. Alphanumeric columns needing conversion to a different binary representation are not a standalone DMU classification category - the DMU's primary categories focus on validity issues, size breaches, and columns already compatible.
• E. Numeric column data does not expand in size during Unicode character set migration because numeric types use fixed-width binary storage, so this is not a valid DMU classification category.
• F. Alphanumeric columns requiring no conversion are not listed as one of the distinct DMU column classification categories that the tool uses to report migration issues.
