How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?
A. With Secure Fabric isolation, each Storage Server runs multiple KVM guests each dedicated to a Database VM cluster using a dedicated network partition and VLAN ID. This provides security and isolation between multiple tenants or VM clusters.
B. With Secure Fabric isolation, each Database VM Guest uses a dedicated network partition and VLAN ID for client networking between application servers. This improves security by preventing man in the middle attacks.
C. With Secure Fabric isolation, each Database VM Cluster uses a dedicated network partition and VLAN ID for Data Guard networking between the primary and disaster recovery Exadata racks. This improves security by isolating data guard traffic onto an encrypted network between data centers.
D. 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.
Which two statements are correct about adding an additional database server to a physical Exadata X9M Database Machine using Oracle Exadata Deployment Assistant (OEDA)?
A. Do not proceed if the OEDA Validate Configuration File step displays an error message about missing files p6880880.zip.
B. Executing /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server is required to reclaim disk space and perform partition reconfiguration.
C. In order to configure the servers with Oracle Exadata Deployment Assistant (OEDA), the new server information must be entered in OEDA, and the configuration file must contain existing nodes.
D. The applyElasticConfig.sh script performs network configuration for the new servers. The new servers are restarted at the end of the process.
E. It is required to install OEDA on the first new database server.
You want to monitor how a large production table is accessed. Especially, you are interested to see how the access on that particular table leverages the benefits of the Exadata Platform.
Which two actions are NOT appropriate for that purpose?
A. YOU query VSSYSTEM_EVENTS and filter for the event 'cell physical IO interconnect bytes returned by smart scan', associated to your table.
B. You query v$segment_statistics and filter for the Object ID of your table from dba_objects and the the column STATISTIC_NAME='optimized physical reads'.
C. You query v$SYSTAT and filter for the statistic 'cell smart table scan', associated to your table.
D. You run the CellCli-command list activerequest , filtering for the attributes ioReason and objectNumber, that you specify as 'Smart Scan' and the Object ID of your table from DBA_OBJECTS.
You are adding a disk expansion kit to a running Exadata X8M Database Machine's Database Servers, and have a filesystem layout that includes:

A. # lvextend -L +20G --verbose /dev/mapper/VGExaDb-LVDbOral
B. # xfs_growfs /uOl +20G
C. # resize2fs +20G /dev/VGExaDb/LVDbOral
D. # lvextend -L +20G --verbose /dev/VGExaDb/LVDbOral

D. ASR can upload configuration metadata to support problem resolution.
E. ASR Manager opens a service request (SR) automatically after sensors detect hardware faults.
F. ASR communicates with Oracle support services using HTTPS.
