CCNA: Cisco Certified Network Associate — Question 208

Which CRUD operation modifies an existing table or view?

Answer options

• A. read
• B. update
• C. replace
• D. create

Correct answer: B

Explanation

The 'update' operation is specifically designed to modify existing records in a table or view, making it the correct answer. 'Read' retrieves data without making changes, 'replace' does not exist as a standard CRUD operation, and 'create' is used to add new records rather than modifying existing ones.
