Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q45-Q50):

NEW QUESTION # 45
What is the minimum Oracle Linux version required to support RoCE and Persistent Memory?

A. Oracle Linux 7.9
B. Oracle Linux 7.5
C. Oracle Linux 8.0
D. Oracle Linux 7.7

Answer: C

Explanation:
RoCE, or Remote Direct Memory Access over Converged Ethernet, is a high-speed networking technology that allows data to be transferred between servers, storage, and other devices over Ethernet. Persistent Memory is a form of non-volatile memory that can be used to store data without losing it when power is lost.
Oracle Linux 8.0 supports both RoCE and Persistent Memory, allowing Exadata systems to leverage the benefits of both technologies. For more information on Oracle Linux 8.0 and its features, refer to the Oracle Exadata Database Machine X9M Implementation Essentials official text book and resources.

NEW QUESTION # 46
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 and execute the script on all storage servers using the EXACLI command.
B. Copy the script to all storage servers using the dcli command and manually execute it on all storage servers using the EXACLI command.
C. Copy the script to all storage servers using the CELLCLI command and execute it on all storage servers in parallel using the CELLCLI command.
D. Copy and execute the script on all storage servers using the dcli command.
E. Copy the script to all storage servers using the dcli command and manually execute it on each storage server using the DCLI command.

Answer: D

NEW QUESTION # 47
You have been notified by your Network Administrator that an upstream switch has been replaced due to a hardware fault. Which command verifies that the client network on your Exadata X9M-2 Database Server is available via both client switches?

A. cat /proc/net/bonding/bondeth0
B. ifconfig -a legrep "re0| re1"
C. netstat -rn
D. /opt/oracle.SupportTools/ibdiagtools/checkbadlinks.p1 -all

Answer: A

Explanation:
According to Oracle's documentation1, the client network on Exadata X9M-2 Database Server is used for client access to the database servers using Single Client Access Name (SCAN) and Oracle RAC Virtual IP (VIP) addresses. To verify that the client network is available via both client switches, you can use the command:
cat /proc/net/bonding/bondeth0
This command displays information about the bondeth0 interface, which is used for the client network on Exadata X9M-2 Database Server2. You can check if both interfaces (eth0 and eth1) are active and connected to different switches3.

NEW QUESTION # 48
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 CELLMONITOR account using cellcli interactively on each storage server
B. to the CELLMONITOR account calling CELLCLI on all cells using DCLI
C. to the CELLADMIN account using cellcli interactively on each storage server
D. to the CELLADMIN account by calling CELLCLI on all cells using DCLI
E. to an administrator-created storage server user with appropriate privileges on celldisk objects by calling EXACLI on all cells using exadcli
F. to an administrator-created storage server user with appropriate privileges on celldisk objects by calling CELLCLI on all cells using exadcli

Answer: C,D,F

Explanation:
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

NEW QUESTION # 49
Which two statements are true about applying updates on Exadata systems?

A. Failed storage server updates are automatically rolled back to a previous release.
B. When running a "yum update" for a new Exadata release, all other repositories should be disabled.
C. For regular Exadata updates, yum automatically installs a non-UEK kernel, which can be selected to boot from grub.
D. Failed database server updates are rolled back to a working state on a previous release automatically.
E. Updating kernel and RDMA packages on storage cells should be prevented by excluding them with the yum -exclude option.
F. To speed up applying storage server updates in a rolling manner, updating two storage servers simultaneously is recommended.

Answer: C,D
