NEW QUESTION # 67
How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?

  • A. 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.
  • 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 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.
  • D. 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.

Answer: A

Explanation:
Exadata Secure RDMA Fabric isolation is a feature that allows you to use virtualization on the X9M-2 platform while maintaining security and isolation between multiple tenants or VM clusters. Secure Fabric isolation works by creating a dedicated network partition and VLAN ID for each Database VM cluster, which is used for cluster networking between the database servers in the VM Cluster. This ensures that the network traffic of each VM cluster is isolated from the others, and it prevents unauthorized access to the data or resources of other VM clusters. Secure Fabric isolation can also be used for other purposes such as client networking, Data Guard traffic, but it's mainly used to provide security and isolation between multiple tenants or VM clusters.


NEW QUESTION # 68
Which two statements are true about Auto Service Request (ASR) with an Exadata Database Machine?

  • A. ASR can upload configuration metadata to support problem resolution.
  • B. ASR communicates with Oracle support services using HTTPS.
  • C. ASR Manager opens a service request (SR) automatically after sensors detect hardware faults.
  • D. ASR Manager must be installed and configured on one of the database servers.
  • E. Configuring ASR is mandatory for all Database Machine assets.
  • F. ASR Manager must be installed and configured on a dedicated server external to the Database Machine.

Answer: C,F


NEW QUESTION # 69
Which three statements are true concerning the configuration or use of Enterprise Manager Cloud Control to monitor and manage Exadata Database Machine components?

  • A. Oracle management agents must only be installed on one compute node in a Database Machine to enable monitoring and management of all compute nodes and storage nodes.
  • B. Cloud Control cannot monitor partitioned Exadata Database Machine systems.
  • C. Oracle management agents must only be installed on one storage node in a Database Machine to enable monitoring and management of all storage node.
  • D. Compute nodes forward their SNMP traps to the Management Server process on the same compute node.
  • E. Storage nodes forward their SNMP traps to the Management Server process on the same storage node.
  • F. Cloud Control can monitor and manage a Database Machine storage Expansion rack.

Answer: A,C,F

Explanation:
Oracle Enterprise Manager (EM) Cloud Control provides comprehensive monitoring and management for Exadata Database Machines, including:
Support for Database Machine Storage Expansion Racks: EM Cloud Control seamlessly integrates with the Storage Expansion Rack, allowing administrators to monitor both primary and expansion storage environments together, which is essential for large-scale deployments.
Minimal Agent Installation: Cloud Control needs only one Oracle Management Agent on one compute node to monitor the entire Database Machine cluster, covering all compute and storage nodes. This is due to Exadata's interconnect and resource-sharing capabilities, enabling centralized monitoring with minimal setup requirements.
