질문 # 58
Your customer needs to ensure that their data is available on the Exadata machine during updates. The customer wants to be able to update one server at a time but still be protected against single-node server failure.
What ASM redundancy level should they use?

• A. Sparse
• B. Extended
• C. High
• D. External
• E. Normal

정답：E

설명：
Your customer needs to ensure that their data is available on the Exadata machine during updates. The customer wants to be able to update one server at a time but still be protected against single-node server failure. This means that they need a redundancy level that can tolerate at least one disk failure without losing data availability or performance. Therefore, the best option for them is normal redundancy . Normal redundancy provides two-way mirroring by default, which means that each data extent has a primary copy and a mirror copy on different disks in different failure groups1. A failure group is a subset of disks within a disk group that are likely to fail at the same time due to common dependencies2. On Exadata Database Machine , each Storage Server is considered as a failure group by default2. This means that if one Storage Server fails or needs to be updated , the data on its disks can still be accessed from another Storage Server that has the mirror copies of the same data extents2. Therefore, normal redundancy ensures data availability and performance during updates or single-node server failures.

질문 # 59
What are two recommended configuration best practices for backup and recovery on Exadata?

• A. Placing the backup network on dedicated switches installed in the top of the rack (ToR) has the benefits of isolating the backup network from other workloads and providing a greater level of control.
• B. The internal Recovery Appliance backup and restore processing is optimized when the RMAN FILESPERSET parameter is set to 1 for the level 1 incremental backup set.
• C. Even if the backup was limited to writing to four tape drives, eight channels could be specified to expedite the restore process.
• D. When off-site long-term backup retention is needed, use Oracle Database Backup Cloud Service as a low-cost, offsite scalable storage for a disaster recovery solution.

정답：B,C

질문 # 62
You use Enterprise Manager to monitor all the components of your Exadata Database Machine.
Recently, you discovered that certain asmdisks were offline in one of the diskgroups used by the rac database called prod.
In which two sources would you find diagnostic messages related to this problem?

• A. Enterprise Manager Alerts on the ILOM home page for cell connectivity problems for the prod database instances
• B. Enterprise Manager Alerts on the Exadata Storage Server Grid home page
• C. alert logs for the prod database instances
• D. alert logs for Enterprise Manager
• E. alert logs for the ASM instances

정답：C,E

설명：
According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources, you can find diagnostic messages related to this problem in the alert logs for the ASM instances and the alert logs for the prod database instances. The alert logs for the ASM instances will provide information related to the offline asm disks, while the alert logs for the prod database instances will provide information related to whether the prod database instances are connected to the ASM instance or not.
