NEW QUESTION 20
You performed an incremental level 0 backup of a database:
RMAN > BACKUP INCREMENTAL LEVEL 0 DATABASE;
To enable block change tracking after the incremental level 0 backup, you issued this command:
SQL > ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE
‘/mydir/rman_change_track.f’;
To perform an incremental level 1 cumulative backup, you issued this command:
RMAN> BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE;
Which three statements are true?
- A. Backup change trackingwill sometimes reduce I/O performed during cumulative incremental backups.
- B. More than one database block may be read by an incremental backup for a change made to a single block.
- C. The change tracking file must always be backed up when you perform a full database backup.
- D. Block change tracking will always reduce I/O performed during cumulative incrementalbackups.
- E. The incremental level 1 backup that immediately follows the enabling of block change tracking will not read the change tracking file to discover changed blocks.
Answer: B,D,E
Explanation:
Oracle Block Change Tracking
Once enabled; this new 10g feature records the modified since last backup and stores the log of it in a block change tracking file using the CTW (Change Tracking Writer) process.
During backups RMAN uses the log file to identify the specific blocks that must be backed up. This improves RMAN’s performance as it does not have to scan whole datafiles to detect changed blocks. Logging of changed blocks is performed by the CTRW process which is also responsible for writing data to the block change tracking file.
Note:
* An incremental level 0 backup backs up all blocks that have ever been in use in this database.
NEW QUESTION 21

- C. Tables cannot be renamed during an import operation.
- D. Only data can be compressed during an export operation.

NEW QUESTION 22
Which two statements are true about the Oracle Direct Network File system (DNFS)? (Choose two.)
- A. Direct NFS can load-balance I/O traffic across multiple network adapters.
- B. It utilizes the OS file system cache.
- C. Oracle Disk Manager can manage NFS on its own, without using the operating kernel NFS driver.
- D. A traditional NFS mount is not required when using Direct NFS.
- E. Direct NFS is available only in UNIX platforms.
Answer: A,C
Explanation:
E: Performance is improved by load balancing across multiple network interfaces (if available).
Note:
* To enable Direct NFS Client, you must replace the standard Oracle Disk Manager (ODM) library with one that supports Direct NFS Client.
Incorrect:
Not A: Direct NFS Client is capable of performing concurrent direct I/O, which bypasses any operating system level caches and eliminates any operating system write-ordering locks
Not B:
* To use Direct NFS Client, the NFS file systems must first be mounted and available over regular NFS mounts.
* Oracle Direct NFS (dNFS) is an optimized NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS storage devices (accessible over TCP/IP).
Not D: Direct NFS is provided as part of the database kernel, and is thus available on all supported database platforms – even those that don’t support NFS natively, like Windows.
Note:
* Oracle Direct NFS (dNFS) is an optimized NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS storage devices (accessible over TCP/IP). Direct NFS is built directly into the database kernel – just like ASM which is mainly used when using DAS or SAN storage.
* Oracle Direct NFS (dNFS) is an internal I/O layer that provides faster access to large NFS files than traditional NFS clients.
NEW QUESTION 23
Examine the parameter settings in your local ORCLdatabase:
Examine the parameter settings for the remote SALESdatabase:
As the SYSuser, you issue the following command on ORCL:
CREATE PUBLIC DATABASE LINK sales.us.example.com USING ‘sales1’;
The sales1tnsnames entry points to the sales database instance.
Which two are requirements to ensure that you can successfully connect by using this database link?
(Choose two.)
- A. Only the user creating the database link must have an account and the required privileges in the remote database.
- B. Local database users who use this database link should have accounts and the required privileges in the remote database.
- C. The GLOBAL_NAMESinitialization parameter should be set to FALSEin the ORCLdatabase.
- D. The SALES1net service name should be known to both the local and remote databases.
- E. The REMOTE_OS_AUTHENTinitialization parameter should be set to FALSE in the remote database.
Answer: B,C
NEW QUESTION 24
Your database supports an online transaction processing (OLTP) application. The application is undergoing some major schema changes, such as addition of new indexes and materialized views. You want to check the impact of these changes on workload performance.

- A. SQL Access Advisor
- B. SQL Performance Analyzer
- C. SQL Tuning Advisor
- D. Automatic Workload Repository compare reports
- E. Database replay
Answer: B

* Gathering optimizer statistics
* SQL tuning actions, such as creating SQL profiles
