How many 128GB Persistent Memory DIMMS are included in Exadata X9M-2 Extended (XT) Storage Servers?

• A.8
• B.12
• C.2
• D.0

You are planning the monitoring configuration for your Exadata X9M Database Machine.
Which three components are monitored directly through the use of Exadata-specific Enterprise Manager Plug-Ins?

• A.the RDMA over Converged Ethernet (RoCE) switches
• B.Hybrid Columnar Compression (HCC) ratios on Extended (XT) storage servers
• C.the Power Distribution Units (PDUs)
• D.Oracle clusterware on the database server
• E.ASM instances
• F.the storage server ILOM

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

You have been asked to design a backup solution for an Exadata X9M-2 Quarter Rack with Extreme Flash Storage Servers connected to a new ZFS Storage Appliance ZS7 with 2 Storage Controllers with 100Gb Ethernet cards and 3 Storage Trays. You are using Oracle Exadata Configuration Assistant to validate the rack layout.
1. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU10.
2. Use drop down to add ZFS Storage Appliance Controllers.
3. You cannot add ZFS Storage Appliance to an Exadata Rack.
4. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU1.
5. Use drop down to add ZFS Storage Trays.
6. Use "Add Equipment" to add the Exadata X9M Database Servers, starting from RU16.
7. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU1.
8. Use drop down to add Exadata X9M EF Storage Servers.
9. Use "Add Equipment" to add the ZFS Storage Controllers, starting from RU27.
10. Use drop down to add Exadata X9M Database Servers.
11. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU31.
Which of these steps are correct and what is their correct order?

• A.3
• B.10, 8, 2, 5
• C.4,1, 6, 9
• D.10, 8, 9, 11
• E.7,6,9,11

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 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.
• C.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.
• 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.
