질문 # 62
You are planning the monitoring configuration for your Exadata X9M Database Machine.
Which three components are monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins?

A. Oracle clusterware on the database server
B. the Power Distribution Units (PDUs)
C. the RDMA over Converged Ethernet (RoCE) switches
D. Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers
E. ASM instances
F. the storage server ILOM

정답：A,D,E

설명：
Exadata-specific Enterprise Manager Plug-Ins are used to monitor different components of the Exadata Database Machine.
1. ASM instances: The Automatic Storage Management (ASM) instances can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the storage space, disk usage, and performance of the ASM instances.
2. Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers: The HCC ratios on Extended (XT) storage servers can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the compression ratios and performance of the storage servers.
3. Oracle clusterware on the database server: The Oracle clusterware on the database server can be monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins. This allows you to monitor the health and performance of the clusterware.

질문 # 63
Which two statements are true about Exadata System Software metrics and alerts on an Exadata Database Machine?

A. Metrics have no thresholds set on them by default.
B. Metric thresholds, if set, will persist across storage and database server reboots.
C. Metric alert notifications can be sent to only one destination such as Enterprise Manager OR SNMP OR SMTP.
D. SMTP metric alert notifications must be sent to both ASR manager and Enterprise Manager agents.
E. Metric alerts are never stateful.

정답：A,B

설명：
Exadata System Software metrics and alerts work as follows:
Persistence of Thresholds: When metric thresholds are configured, they remain active and persist across server reboots. This ensures consistent monitoring behavior even after maintenance or unexpected reboots .
Default Metrics: By default, metrics are collected without predefined thresholds. Administrators must set custom thresholds to enable specific alerting based on their operational requirements.

질문 # 64
You have a script with several CELLCLI commands that must be executed on each cell in your Exadata full rack. The script must run on each cell simultaneously. How must you achieve this?

A. Copy the script to all storage servers using the dcli command and manually execute it on each storage server using the DCLI command.
B. Copy the script to all storage servers using the CELLCLI command and execute it on all storage servers in parallel using the CELLCLI command.
C. Copy and execute the script on all storage servers using the dcli command.
D. Copy and execute the script on all storage servers using the EXACLI command.
E. Copy the script to all storage servers using the dcli command and manually execute it on all storage servers using the EXACLI command.

정답：B

설명：
This can be done by using the 'cellcli -e' command, which allows you to execute commands in parallel on all storage servers. For more information about executing CELLCLI commands in parallel, please refer to the Oracle Exadata Database Machine X9M Implementation Essentials official text book and resources [1][2].

질문 # 65
Which two statements are true about Auto Service Request (ASR) with an Exadata Database Machine?

A. ASR can upload configuration metadata to support problem resolution.
B. Configuring ASR is mandatory for all Database Machine assets.
C. ASR Manager must be installed and configured on one of the database servers.
D. ASR communicates with Oracle support services using HTTPS.
E. ASR Manager must be installed and configured on a dedicated server external to the Database Machine.
F. ASR Manager opens a service request (SR) automatically after sensors detect hardware faults.

정답：D,E

설명：
A and F are true statements about Auto Service Request (ASR) with an Exadata Database Machine [1][2]. In order to use the ASR feature, ASR Manager must be installed and configured on a dedicated server which is external to the Database Machine, and it communicates with Oracle support services using HTTPS. Additionally, ASR can upload configuration metadata to support problem resolution, and it can open a service request (SR) automatically after sensors detect hardware faults.
Reference for this information can be found in the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources [1][2].

질문 # 66
A new Exadata Quarter Rack with 2 Database Servers and 3 HC Storage Servers and 3-phase 15kVA PDUs is being installed in a Data Center. However, the Data Center is only providing enough power for a single cable from each PDU.
Which statement is correct?

A. The power cables from the servers to the PDUs can be rearranged inside the rack following OECA guidance to utilize a single PDU power cable.
B. The installation cannot proceed until two power feeds are available per PDU.
C. A splitter cable can be used to provide power to all PDU cables.
D. The installation can go ahead, no change is required.

정답：A
