Curious about Actual Oracle Engineered Systems (1Z0-902) Exam Questions?

Correct : D

The correct order of steps is 10, 8, 9, 11. The 10th step is to use the drop down to add Exadata X9M Database Servers, the 8th step is to use the drop down to add Exadata X9M EF Storage Servers, the 9th step is to use 'Add Equipment' to add the ZFS Storage Controllers, and the 11th step is to use 'Add Equipment' to add the ZFS Storage Trays. These steps are referenced in the Oracle Exadata Database Machine X9M Implementation Essentials Official Textbook, which is available online athttps://docs.oracle.com/cd/E80437_01/E80437/html/index.html.

Correct : C

This command is based on the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and other resources. This command sets the power state of the system to ON and starts the storage server. It is the only command that is able to start the storage server remotely. All the other commands are incorrect or require the user to be physically present in the data center.

Correct : D

According to Oracle's documentation1, to set a threshold for a metric on a database server, you need to use thecreate thresholdcommand with the appropriate parameters.Theset thresholdcommand is used to modify an existing threshold2.

Therefore, the command that you should use to generate alerts for such an event is:

dbmcli -e ''create threshold ds_temp comparison='>', critical=30'' on each database server1

Correct : D

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.

Correct : D

Exadata Secure RDMA Fabric isolation is a feature that allows you to use virtualization on the X9M-2 platform while maintaining security and isolation between multiple tenants or VM clusters. Secure Fabric isolation works by creating a dedicated network partition and VLAN ID for each Database VM cluster, which is used for cluster networking between the database servers in the VM Cluster. This ensures that the network traffic of each VM cluster is isolated from the others, and it prevents unauthorized access to the data or resources of other VM clusters. Secure Fabric isolation can also be used for other purposes such as client networking, Data Guard traffic, but it's mainly used to provide security and isolation between multiple tenants or VM clusters.

According to Oracle's documentation1, Exadata Secure RDMA Fabric Isolation is a feature that enables strict network isolation for Oracle Real Application Clusters (Oracle RAC) clusters on Exadata Database Machine systems that use RDMA over Converged Ethernet (RoCE). Exadata Secure RDMA Fabric Isolation uses RoCE VLANs to ensure that network packets from one VM cluster cannot be seen by another VM cluster.VLAN tag enforcement is done at the KVM host level, which means that security cannot be bypassed by any software exploits or misconfiguration on the database server VMs1.

Therefore, the statement that is true about how Exadata Secure RDMA Fabric isolation is used in X9M-2 with virtualization enabled is:

With Secure Fabric isolation, each Database VM cluster uses a dedicated network partition and VLAN ID for cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.
