Later, user USER1 ran an application that inserted 100,000 rows into table T1. The following query is frequently ran against the T1 table: SELECT deptno, empno, deptname FROM t1 WHERE deptno = 'EN' AND empno = '123' Assuming current statics exist for the table and index, which index will provide optimal performance for this query? A. CREATE INDEX idx1 ON t1 (deptno, empno) INCLUDE (deptname) B. CREATE INDEX idx1 ON t1 (deptno, empno) C. CREATE INDEX idx1 ON t1 (deptno) INCLUDE (empno) D. CREATE INDEX idx1 ON t1 (deptno) Answer: B QUESTION NO: 5 Given INTRA_PARALLEL is OFF, average row length is 900 bytes, and temporary table cardinality is 1000, which setting would prevent a SORTHEAP overflow when the temporary table is sorted? A. SORTHEAPTHRES 10000K, SORTHEAP 250K B. SORTHEAPTHRES 10000K C. SORTHEAP AUTOMATIC, SHEAPTHRES 10000K D. SORTHEAP AUTOMATIC, SHEAPTHRES 0 Answer: D QUESTION NO: 6 Setting the DB2_FMP_COMM_HEAPSZ=0 will result in which the following? A. User-defined function calls will be disabled. B. In a partitioned environment, infinite communications will be enabled between partitions. C. In a partitioned environment, communications will not be buffered. D. Non-fenced routines can beinvoked, however automatic database maintenance will be disabled. Answer: D QUESTION NO: 7 Your UNIX system administrator has indicated that there appears to be a lot of I/O wait time associated with your database, which is stored in a 7+p RAID array. An investigation reveals the following information: DB2_PARALLEL_IO=* Tablespace with ID 7 has a single container and is dedicated to the largest table. It has a page size of 16K, an extent size of 32, and a prefetch size of 64. Which setting would optimize I/O for the largest table? A. DB2_PARALLEL_IO=7:64 B. DB2_PARALLEL_IO=7:7 C. DB2_PARALLEL_IO=7:16 D. DB2_PARALLEL_IO=7:32 Answer: B QUESTION NO: 8 Which command CANNOT be used to explicitly build a compression dictionary for a table? A. REORG B. LOAD C. INSPECT D. IMPORT Answer: D QUESTION NO: 9 What determines the degree of inter-partition parallelism used? A. The number of database partitions and the definition of partition groups. B. The number of database connections and the definition of partitions groups. C. The value of the INTER_PARALLEL Database Managerconfiguration parameter. D. The value of the DFT_DEGREE database configuration parameter. Answer: A QUESTION NO: 10 Which statement about compression and temporary tables is NOT correct? A. When executing queries that require temporary tables, DB2 considers the storage savings and the impact to query performance to determine whether compression is worthwhile. B. Compression is only applied to created temporary tables that were defined with the CREATE TEMPORARYTABLE ?COMPRESS YES statement. C. The minimum size that a table must be before compression is used is larger for temporary tables than for regular tables. D. The explain facility and the db2pd utility can be used to determine whether a temporary table has been compressed. Answer: B
