문제3

Why is ASM High redundancy an important configuration choice when rolling Exadata Storage Server patching is planned?

A. High redundancy protects from partner disk failure while a cell is offline being updated.

B. High redundancy speeds up ASM fast mirror resync when a cell is brought back online after patching.

C. High redundancy forces ASM rebalance before allowing disks to be taken offline.

D. Normal redundancy provides the same protection during rolling patching, so High redundancy is not important inthis case

문제4

Your customer has purchased their brand new Exadata Database Machine X3-2 Full rack to achieve 20-TB-per-hour backups on their 300 TB database.

You have been called to determine why they are not able to achieve even half that rate. Use the information in the image below to identify two reasons their backups are still slow.

A. The Media Server to Tape Library transfer is causing a bottleneck.

B. Exadata backups are being performed using RMAN over the 10 Gigabit Ethernet network.

C. LVM snapshots are not configured properly on the Database Server.

D. The number of database servers is causing a bottleneck.

E. The number of tape drives is causing a bottleneck.

문제5

A customer has three databases named CC. FIN, and DW. The CC database is for their CallCenter. Even a slight decrease in the response time of the database would mean more people "on hold" in their data center. The orders received through the CallCenter are stored in the Finance (FIN) database. Both databases, CC and FIN, serve as sources for the Data Warehouse (DW) database. All databases use the same Automatic Storage Management (ASM) diskgroup and therefore, the same physical disks on Exadata storage. The customer wants to dynamically control the resources that are available for the CallCenter database because this has direct impact on their operations?
Which option should be implemented?

A. IORM and DBRM

B. DBRMon the CC database

C. DBRM on all the databases

D. IORM, because DBRM cannot be changed for an existing session

정답: B

문제6

Identify two ways to reduce the risks associated with the software updates that are performed on a production Exadata system.

A. Create a system-wide firmware and software snapshot first.

B. Test on an Exadata system that is identical to the production system first.

C. Updating an engineered system has no risk.

D. Patch all systems at once instead of one at a time.

E. Patch on the standby system first by using Data Guard Standby First Patch Apply.
