（B）dbmcli -e "LIST METRICHISTORY WHERE name LIKE 'DS_.*'"

（A）The installation can go ahead, no change is required.

（B）A splitter cable can be used to provide power to all PDU cables.

（C）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.

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

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

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

（C）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.

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

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

（B）shutdown -h now' on the affected storage server

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

（D）CellCLI alter GRIDDISK all inactive on the affected storage server

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

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

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

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

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

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

（E）When running a "yum update" for a new Exadata release, all other repositories should be disabled.

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

（A）using the CELLCLI CALIBRATE command on the storage server after logging in as the root user

（B）using the CELLCLI list LUN DETAIL command as the celladmin user

（C）using the CELLCLI CALIBRATE command on the storage server after logging in as the celladmin user

（D）hardware monitoring using the storage server ILOM

（A）the number of Smart Scans performed for the table on all the storage servers, as shown when performing a list activerequest command using CELLCLI on all the cells

（B）the number of Smart Scans performed for the table on all the storage servers, as shown when performing a list ACTIVEREQUEST command using EXACLI on all the cells

（C）the number of parallel queries that accessed the table

（D）the number of serial queries that accessed the table

（E）the number of full table scans that accessed the table

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

（B）# resize2fs +20G /dev/VGExaDb/LVDbOral

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

（D）# xfs_growfs /uOl +20G

（A）No thresholds need to be set because they are preset in the ILOM and these are sufficient for monitoring.

（B）Set thresholds in ILOM and in Enterprise Manager because they are not preset anywhere and must be set in both places.

（C）No thresholds need to be set because they are preset in the ILOM and in Enterprise Manager

（D）Set thresholds only in ILOM because they are not preset anywhere but need to be set only in ILOM.
