NEW QUESTION 30
Which two statements are correct about adding an additional database server to a physical Exadata X9M Database Machine using Oracle Exadata Deployment Assistant (OEDA)?

Do not proceed if the OEDA Validate Configuration File step displays an error message about missing files p6880880.zip.

Executing /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server is required to reclaim disk space and perform partition reconfiguration.

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.

The applyElasticConfig.sh script performs network configuration for the new servers. The new servers are restarted at the end of the process.

It is required to install OEDA on the first new database server.

Which two actions are NOT appropriate for that purpose?

YOU query VSSYSTEM_EVENTS and filter for the event ‘cell physical IO interconnect bytes returned by smart scan’, associated to your table.

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’.

You query v$SYSTAT and filter for the statistic ‘cell smart table scan’, associated to your table.

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.

NEW QUESTION 37
How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?

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.

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.

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.

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.

NEW QUESTION 38
How do ASM failure groups provide redundancy?

Failure groups are created for each grid disk to ensure mirror copies are written to the same storage server for faster recovery after a physical disk failure.

Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.

They ensure that the ASM Flex instances are enabled on a maximum of two database servers or VMs per cluster.

Extended Redundancy mirrors data across data centers providing the highest levels of data protection.

NEW QUESTION 39
What is the maximum DRAM capacity you can expand an X9M-2 DB Server?

1536GB

512GB

2048GB

768GB

1024GB

384GB

NEW QUESTION 40
An Exadata X9M-2 Elastic Rack with 4 Database Servers and 8 HC Storage Servers and 3-phase 24kVA 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 splitter cable can be used to provide power to all PDU cables.

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.

The installation cannot proceed until two power feeds are available per PDU.

The installation can go ahead, no change is required.

NEW QUESTION 41
Which four actions should you take before proceeding with applying updates to your Exadata Database Machine?

Consult My Oracle Support note 888828.1 to determine the current recommended Exadata software release.

Run exachk and resolve only WARNINGS that you have not seen before.

Run the appropriate patchmgr preqequisite check step for each component being updated.

Run patchmgr –all_comp -autofix -autobackup -upgrade -rolling.

For database servers, perform a server backup using patchmgr -dbnodes db_list_file -backup -rolling.

NEW QUESTION 45
Which two statements are false about backup to ZFS Storage Appliance (ZFSSA)?

ZFSSA may connect directly to the Exadata 100Gb RoCE network switches.

Top of Rack (ToR) switches are managed as part of the hardware stack and software levels are upgraded during the patching process.

When backing up multi-rack systems, sharing Exadata X9M switches is recommended.

ZFS Snapshots can provide rapid cloning of development and test environment.

NEW QUESTION 46
What are two recommended configuration best practices for backup and recovery on Exadata?

Placing the backup network on dedicated switches installed in the top of the rack (ToR) has the benefits of isolating the backup network from other workloads and providing a greater level of control.

Even if the backup was limited to writing to four tape drives, eight channels could be specified to expedite the restore process.

The internal Recovery Appliance backup and restore processing is optimized when the RMAN FILESPERSET parameter is set to 1 for the level 1 incremental backup set.

When off-site long-term backup retention is needed, use Oracle Database Backup Cloud Service as a low-cost, offsite scalable storage for a disaster recovery solution.
