10. Management Server (MS)
What is the correct location where these software components can run in the standard Exadata Database Machine deployment?

A. 3, 4, 8, and 10 run on the database servers; 1, 2, 5, 6, 7 and 9 run on the Exadata storage servers.
B. 1, 2, 3, 4, 8 and 9 run on the database servers; 5, 6, 7, 9 and 10 run on the Exadata storage servers.
C. 1, 2, 3, 4, 9 and 10 run on the database servers; 5, 6, 7, 8, 9, and 10 run on the Exadata storage servers.
D. 2, 3, 4, 8, and 10 run on the database servers; 1, 5, 6, 7and 9 run on the Exadata storage servers.
E. 1, 2, 3, 4, 5, 8, 9 and 10 run on the database servers; 5, 6,7, 9 and 10 run on the Exadata storage servers.

答案：B

解題說明：
Oracle KVM Guest, Oracle Enterprise Manager Agent (OMA), RDBMS instance, Automatic Diagnostic Repository Command Interpreter (ADRCI), CELLCLI, diskmon, and Restart Server (RS) can all run on the database servers. The Cell Server (CELLSRV) and Management Server (MS) can both run on the Exadata storage servers. Specific instructions for installing and configuring these software components can be found in the book and can be referenced here: https://docs.oracle.com/cd/E80920_01/E80920/html/x9m_software_components.html.

問題 #87
Which are two correct statements about backing up Exadata Database Machine?

A. Use a snapshot-based backup of an Oracle Exadata Database Machine database server software.
B. Backup of the Oracle Cluster Registry, which also contains Voting Disk information, is automatically maintained on the file system of the first database server.
C. The M.2 disk is hot pluggable and can be replaced when the power is on, but you will have to restore the system data manually.
D. Backing up Exadata Storage Server Software is critical for restoration.
E. For high availability, system area can be on the first two disks and M.2 devices.

答案：A,C

問題 #88
Which three statements are true about the Grid Infrastructure configuration after a nonvirtual deployment of a new Exadata Database Machine with a single cluster?

A. The OCR is multiplexed in the DATA_<DBM__NAMe> and RECo_<dbm_name> diskgroups.
B. Three Single Client Access Name (SCAN) listeners are configured on the RDMA over Converged Ethernet (RoCE) network.
C. The ora. diskmon clusterware resource is enabled and online.
D. Three Single Client Access Name (SCAN) listeners are configured on the client access network.
E. Grid Naming Service (GNS) is not configured.
F. Grid Infrastructure uses the management network as the cluster interconnect.

答案：A,B,C

解題說明：
For a non-virtual deployment of Oracle Exadata with a single cluster:
Single Client Access Name (SCAN) Listeners: By default, three SCAN listeners are configured on the RDMA over Converged Ethernet (RoCE) network. This setup allows for load balancing and high availability of incoming client connections across the cluster nodes.
Oracle Cluster Registry (OCR) Multiplexing: The OCR is typically stored in multiple locations within the disk groups to enhance reliability and fault tolerance. On Exadata, the OCR is multiplexed across the DATA and RECO disk groups for enhanced resilience.
ora.diskmon Resource: This is an essential component of Oracle Clusterware, responsible for monitoring and managing disk-related cluster resources. It is always enabled and kept online by Oracle Clusterware on Exadata systems.

問題 #89
Which are two valid reasons for executing an X9M-2 Exadata storage server rescue procedure?

A. moving all disks from one cell to another as part of a chassis-level component failure
B. corruption in the / (root) filesystem
C. the failure of physical disk 1
D. accidental loss of all data from all griddisks in a storage server
E. corruption in a normal or high redundancy ASM diskgroup
F. the failure of both physical M.2 disks
G. the failure of physical disk 0 and 11

答案：B,F

解題說明：
The two valid reasons are:
corruption in the / (root) filesystem . According to 1, this is one of the scenarios that requires a storage server rescue procedure , because it prevents the storage server from booting up normally . The rescue procedure will re-image the root filesystem with a fresh copy of the operating system and restore the configuration files from a backup1.
the failure of both physical M.2 disks . According to 2, each Exadata Storage Server X9M-2 has two physical M.2 disks that store the operating system and configuration files for the storage server . If both M.2 disks fail , then the storage server cannot boot up or function properly . The rescue procedure will replace the failed M.2 disks with new ones and re-image them with the operating system and configuration files2.

問題 #90
You must drop all celldisks on all the storage servers in an X9M-2 quarter rack as part of a reconfiguration project.
Which three statements describe the account on the storage servers which you should use and the tool that may be used to drop the celldisks?

A. to the CELLADMIN account by calling CELLCLI on all cells using DCLI
B. to the CELLMONITOR account using cellcli interactively on each storage server
C. to the CELLMONITOR account calling CELLCLI on all cells using DCLI
D. to an administrator-created storage server user with appropriate privileges on celldisk objects by calling CELLCLI on all cells using exadcli
E. to the CELLADMIN account using cellcli interactively on each storage server
F. to an administrator-created storage server user with appropriate privileges on celldisk objects by calling EXACLI on all cells using exadcli

答案：A,D,E

解題說明：
To drop all celldisks on all the storage servers in an X9M-2 quarter rack, you should use the CELLADMIN account, which has the necessary privileges to perform this task. You can use the CELLCLI command-line interface to drop the celldisks. The best way to do this is by calling CELLCLI on all cells using DCLI (Oracle Database Command Line Interface) which allows you to run commands on multiple servers at once. Alternatively, you can use an administrator-created storage server user with appropriate privileges on celldisk objects by calling CELLCLI on all cells using exadcli. It is not recommended to use the CELLMONITOR account, as it has a more limited set of privileges. It is also important to note that EXACLI is not a valid tool for this task
