    질문 # 34
    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. alert logs for Enterprise Manager
    • B. alert logs for the prod database instances
    • C. Enterprise Manager Alerts on the ILOM home page for cell connectivity problems for the prod database instances
    • D. alert logs for the ASM instances
    • E. Enterprise Manager Alerts on the Exadata Storage Server Grid home page

    정답：B,D

    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.

    질문 # 36
    Which two quarantine types can disable Smart Scan for multiple databases that offload SQL statements to a cell on an Exadata Database Machine?

    • A. SQL Plan Quarantine
    • B. Database Quarantine
    • C. Disk Region Quarantine
    • D. Manually created Quarantine
    • E. Cell Offload Quarantine

    정답：A,E

    설명：
    A and E are the two correct quarantine types that can disable Smart Scan for multiple databases that offload SQL statements to a cell on an Exadata Database Machine. A is correct because SQL Plan Quarantine will disable Smart Scan for all queries related to the SQL plan that was placed in the SQL Plan Quarantine [1]. E is correct because the Cell Offload Quarantine will disable Smart Scan for all queries offloaded to Oracle Database Exadata Storage Server Software [2]. The other statements (B, C, and D) are incorrect.

    질문 # 37
    You are in the process of upgrading your nonvirtualized X9M-2 Database Machine elastic configuration with 4 database servers and 7 HC storage servers with an additional 4 database servers and 7 HC storage servers.
    The new storage servers are called DM01CEL08 through dmoicel14.
    After creating 96 new griddisks, you issued this SQL statement:

    How many failgroups if any, will be added to the DATE diskgroup by executing this SQL statement?

    • A. 7 consisting of 12 griddisks each
    • B. 12 consisting of seven griddisks each
    • C. 1 consisting of all 96 griddisks
    • D. 96 consisting of one griddisk each
    • E. 0 because the new griddisks will be added to the existing faiigroups

    정답：B


    질문 # 38
    I/O performance of the prod database on your Exadata Database Machine has degraded slightly over the past month. The database has been allocated to the OLTP I/O Resource Management (IORM) category.
    Which two monitoring tools might be useful in examining I/O performance for the prod database?

    • A. OS I/O metrics using Enterprise Manager host pages for the storage servers
    • B. I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *p1us
    • C. OS I/O metrics using OS tools such as iostat on the database servers
    • D. OS I/O metrics using OS tools such as iostat on the storage servers
    • E. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk

    정답：B,E

    설명：
    According to the Oracle documentation1, two monitoring tools that might be useful in examining I/O performance for the prod database are:
    cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk (D). This tool can help you monitor the I/O Resource Management (IORM) metrics and identify any bottlenecks or imbalances in the storage layer.
    I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *p1us . These views can help you monitor the I/O activity and latency at the file, function, and consumer group level.
