Q17. Which two statements are true about the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers?

The sparse_<DBM_NAME> diskgroup is created automatically.

There is free space available on the hard disks inside the database servers for possible extension of the /uoi file system.

The DATA_<DBM_Name> and RECO_<DBM_NAME> ASM diskgroups are built on with DATA on the outer-most tracks and RECO on the inner-most tracks of the physical disk.

There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes.

There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs.

Q18. Which dbmcli command is NOT valid on Exadata X9M?

dbmcli -e “LIST METRICHISTORY WHERE name LIKE ‘DS_.*'”

dbmcli -e “LIST METRICCURRENT WHERE name = ‘DS_TEMP’ “

dbmcli -e “LIST IBPORT DETAIL”

dbmcli -e “LIST ALERTHISTORY WHERE agelnMinutes < 15”

Q19. Which two statements are true about applying updates on Exadata systems?

Failed storage server updates are automatically rolled back to a previous release.

To speed up applying storage server updates in a rolling manner, updating two storage servers simultaneously is recommended.

Updating kernel and RDMA packages on storage cells should be prevented by excluding them with the yum -exclude option.

For regular Exadata updates, yum automatically installs a non-UEK kernel, which can be selected to boot from grub.

Failed database server updates are rolled back to a working state on a previous release automatically.

When running a “yum update” for a new Exadata release, all other repositories should be disabled.

Q20. You are adding a disk expansion kit to a running Exadata X8M Database Machine’s Database Servers, and have a filesystem layout that includes:

After running the following commands, which command needs to be run to add 20G of space to the filesystem mounted on /u01?

# lvextend -L +20G -verbose /dev/mapper/VGExaDb-LVDbOral

# xfs_growfs /uOl +20G

# resize2fs +20G /dev/VGExaDb/LVDbOral

# lvextend -L +20G -verbose /dev/VGExaDb/LVDbOral

Q21. Which are two correct statements about backing up Exadata Database Machine?

Backup of the Oracle Cluster Registry, which also contains Voting Disk information, is automatically maintained on the file system of the first database server.

Backing up Exadata Storage Server Software is critical for restoration.

For high availability, system area can be on the first two disks and M.2 devices.

The M.2 disk is hot pluggable and can be replaced when the power is on, but you will have to restore the system data manually.

Use a snapshot-based backup of an Oracle Exadata Database Machine database server software.

Q22. Which three statements are true about Oracle Configuration Manager (OCM) for an Exadata Database Machine?

It is mandatory to install OCM on all database servers.

It collects configuration information automatically.

It collects configuration information on demand.

It is mandatory to install OCM on at least one database server.

Collected configuration information can be uploaded automatically to Oracle.

Collected configuration information can be uploaded manually to Oracle.

Q23. Which statement is true about the patching features provided in Platinum Services?

Oracle Platinum Service covers Exadata storage software and firmware patching, but customers must perform the database patching.

Patching services are available for the full software stack up to twice per year.

The rolling and complete down time approaches are two options to patching.

Patching is done automatically during business hours.

Add 24x 32GB DIMMs.

Q25. Which two statements are true about Auto Service Request (ASR) with an Exadata Database Machine?

ASR Manager must be installed and configured on a dedicated server external to the Database Machine.

Configuring ASR is mandatory for all Database Machine assets.

ASR Manager must be installed and configured on one of the database servers.

ASR can upload configuration metadata to support problem resolution.

ASR Manager opens a service request (SR) automatically after sensors detect hardware faults.

ASR communicates with Oracle support services using HTTPS.

Q26. An Exadata storage server physical disk on an X9M-2 high-capacity full rack entered the predictive failure state. Which two steps must you perform to replace this failed physical disk?

Replace the failed physical disk.

Add the griddisks back into the ASM diskgroup they used to be a member of.

Identify the griddisks located on the failed physical disk and drop them from the associated ASM diskgroups.

Rebalance the data on the effected griddisks before performing a manual drop command.

Create a new celldisk and new griddisks on the replaced physical disk.

Verify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.

Q27. 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?

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

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

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

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.
