IBM DB2 10.1 Advanced DBA for Linux UNIX and Windows Sample Questions:
A DBA wants to create a table named SALES that has the following characteristics:
- Data for the first half of the year will reside in table space TBSP1; the index for this data will reside in table space TBSP21. - Data for the second half of the year will reside in table space TBSP2; the index for this data will reside in table space TBSP22.
Which clause must be used with the CREATE TABLE statement to define this table?
- A. ORGANIZE BY DIMENSIONS
- B. PARTITION BY RANGE
- C. ORGANIZE BY KEY SEQUENCE
- D. DISTRIBUTE BY HASH
A storage group named MED_SG was created as follows: CREATE STOGROUP med_sg ON ?db2fs1? ?db2fs2? '/db2fs3' Then, a table space named TS1 was created in the storage group and two tables (TAB_A and TAB_B) were created in the TS1 table space. Four months later, a DBA discovered that 90% of the space that had been allocated to the MED_SG storage group had been consumed. So, more space was added to the storage group by executing the following command: ALTER STOGROUP med_sg ADD ?db2fs4? ALTER STOGROUP med_sg ADD ?db2fs4 Shortly afterwards, queries against tables in the TS1 table space began to run slower. Which statement should be executed to correct the performance problem?
- A. ALTER STOGROUP med_sg ADD ?db2fs5?ALTER STOGROUP med_sg ADD ?db2fs5
- B. ALTER TABLESPACE ts1 REBALANCE
- C. ALTER TABLESPACE ts1 ADD '/db2fs4' REBALANCE
- D. ALTER STOGROUP med_sg DROP '/db2fs4'
Which statement about value compression is correct?
- A. To use value compression, you must have a license for the DB2 Storage Optimization Feature.
- B. When value compression is used, the byte count of compressed NULLs, zeros, and blanks might be larger than that of the uncompressed version of the same values.
- C. Value compression involves removing duplicate entries for a value, only storing one copy, and keeping track of the location of any references to the stored copy.
- D. Value compression uses a page-level dictionary-based compression algorithm to compress data based on repetition of values found in a single column.
What type of file system is used to store data and logs in a DB2 pureScale environment?
- A. Enhanced Journaled File System (JFS2 or EXT4)
- B. Network File System (NFS)
- C. General Parallel File System (GPFS)
- D. Common Internet File System (CIFS)
In what situation should you use a redirected restore operation?
- A. You want to move data from one operating system to another.
- B. You want to restore you table spaces into new storage groups.
- C. You want to restore your table space containers into a different physical location.
- D. You want to drop a storage group during a restore process.
