Sample IBM Db2 Assessments question Test your knowledge!

Considering IBM Db2's lock timeout behavior, what happens if a transaction holds a lock and an incompatible lock request is made by another transaction, assuming DEFAULT_LOCKTIMEOUT is set to a positive value?

  • The requesting transaction is immediately rolled back.
  • The requesting transaction will wait indefinitely until the lock is released.
  • The requesting transaction will wait for the timeout period and then proceed without the lock.
  • The requesting transaction will wait for the specified timeout period before being rolled back.

When defining a relational table in IBM Db2, which of the following data types allows storage of binary data for a fixed length?

  • BLOB
  • VARCHAR
  • CHAR FOR BIT DATA
  • CLOB
  • DATALINK

Which SQL statement would you use to remove all rows from an IBM Db2 table named 'employee_sales' without logging the individual row deletions?

  • TRUNCATE TABLE employee_sales DROP STORAGE
  • DROP TABLE employee_sales
  • DELETE FROM employee_sales
  • TRUNCATE TABLE employee_sales IMMEDIATE
  • REMOVE * FROM employee_sales

What is the result of the following query in IBM Db2 assuming that the 'sales_data' table exists and has the appropriate columns: SELECT MAX(sale_amount), salesman_id FROM sales_data GROUP BY salesman_id HAVING COUNT(*) > 5?

  • It retrieves the highest sale_amount and corresponding salesman_id for each group of salesmen with more than 5 sales.
  • It shows an error because the HAVING clause cannot use aggregate functions.
  • It retrieves the highest sale_amount for salesmen with more than 5 sales, without showing the salesman_id.
  • It retrieves all the sale_amounts and salesman_ids regardless of the number of sales.
  • It retrieves the total count of sales alongside the salesman_id for those with more than 5 sales.

Which of the following is an acceptable way to enforce data integrity for a 'department_id' field in a table named 'employees' which references a 'department_id' in a 'departments' table?

  • Use a PRIMARY KEY constraint on both 'department_id' fields
  • Use a FOREIGN KEY constraint on 'department_id' in the 'employees' table referencing 'departments'
  • Use a UNIQUE constraint on 'department_id' in the 'employees' table
  • Use a CHECK constraint on 'department_id' in the 'employees' table
  • Use an INDEX on 'department_id' in both tables

Which of the following statements accurately describes isolation levels in IBM Db2 and their impact on locks?

  • Read uncommitted isolation does not acquire any locks, allowing dirty reads.
  • Repeatable read isolation releases shared locks after a query completes but before a transaction ends.
  • Read committed isolation holds exclusive locks until the transaction completes.
  • Cursor stability isolation level prevents other transactions from writing to rows read by the current transaction.
  • Serializable isolation level acquires no locks but uses optimistic concurrency control.
