The BulkAttributeRemover uses a regular expression to identify which attributes to remove.

• A. True
• B. False
• C. It uses a simple match
• D. It uses a numeric index

Answer: (A)

The key idea is pattern-based removal driven by regular expressions. The BulkAttributeRemover is designed to scan attribute names and remove those that match a provided regex pattern. This lets you specify flexible, powerful patterns (for example, removing all attributes that start with a prefix, end with a suffix, or match a naming convention) rather than listing every attribute explicitly.

Using a regex is more versatile than a simple exact-name match, which would require you to specify each attribute individually. It’s also not based on a positional index, since attributes are named entities rather than ordered items. So the statement is true: the BulkAttributeRemover uses a regular expression to identify which attributes to remove.
