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.

How do ASM failure groups provide redundancy?

A.

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.

B.

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

C.

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

D.

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

Which statement is true about the Persistent Memory Commit Accelerator?

A.

Persistent Memory Commit Accelerator tracks changes to Persistent Memory Data Accelerator to ensure duplicate blocks are not written to Flash.

B.

Persistent Memory Commit Accelerator helps to further reduce redo log write latency by using Persistent Memory and Remote Direct Memory Access (RDMA).

C.

Persistent Memory Commit Accelerator copies redo log data from disk for faster redo apply on Data Guard Standby Databases.

D.

Persistent Memory Commit Accelerator contains logging information from all tiers of the software stack for rapid triage and diagnostics.

E.

Persistent Memory Commit Accelerator reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk.

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

A.

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.

B.

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

C.

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.

D.

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.

Which two quarantine types can disable Smart Scan for multiple databases that offload SQL statements to a cell on an Exadata Database Machine?

SQL Plan Quarantine

B.

Manually created Quarantine

C.

Database Quarantine

D.

Disk Region Quarantine

E.

Cell Offload Quarantine

You have been tasked with replacing a memory module of an Exadata Storage Server and need to power off the affected storage server. Which two commands must you execute to safely power off the storage server in an Exadata X9M Database Machine?

A.

CeLLCLI> alter cell shutdown SERVICES all on the affected storage server

B.

CeLLCLI> list GRIDDISK where status != 'inactive' on the affected storage server

C.

'crsct1 stop cluster -all' on one of the database servers

D.

CellCLI LIST GRIDDISK ATTRIBUTES name WHERE asmdeactivationoutcome != 'Yes' on the affected Storage server

E.

CellCLI alter GRIDDISK all inactive on the affected storage server

F.

shutdown -h now' on the affected storage server

You are hardening the security posture of your Exadata Database Machine. Before disabling ssh access to the storage servers, what should you do to enable REST access to the MS process?

A.

Install Oracle Rest Data Services on each Database server and install the MS APEX application.

B.

The MS Process on the storage servers is natively endowed with REST services, but are not enabled by default.

C.

Install Oracle Rest Data Services on each Storage server and install the MS APEX application.

D.

The MS Process on the storage servers is natively endowed with REST services and are enabled by default, however, appropriate roles and users should be created to ensure security.

You have been asked by Oracle Support to check the firmware of the hard & flash disks in a storage server. Which cellcli command should you use to get this information?

B.

list cell attributes name, deviceName, diskType, physicalFirmware

C.

list physicaldisk attributes name, deviceName, diskType, physicalFirmware

D.

list devices attributes name, deviceName, diskType, physicalFirmware

You are planning the monitoring configuration for your Exadata X9M Database Machine.

ASM instances

B.

Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers

C.

the storage server ILOM

D.

the Power Distribution Units (PDUs)

E.

Oracle clusterware on the database server

F.

the RDMA over Converged Ethernet (RoCE) switches
