Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q41-Q46):

NEW QUESTION # 41
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?

A. 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.
B. There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs.
C. There is free space available on the hard disks inside the database servers for possible extension of the /uoi file system.
D. The sparse_<DBM_NAME> diskgroup is created automatically.
E. There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes.

Answer: A,B

NEW QUESTION # 42
Which three statements are true about Oracle Configuration Manager (OCM) for an Exadata Database Machine?

A. It collects configuration information on demand.
B. It is mandatory to install OCM on at least one database server.
C. It is mandatory to install OCM on all database servers.
D. It collects configuration information automatically.
E. Collected configuration information can be uploaded automatically to Oracle.
F. Collected configuration information can be uploaded manually to Oracle.

Answer: A,D,E

Explanation:
It collects configuration information automatically (B). OCM gathers detailed configuration information about a variety of designated Oracle products and components across an enterprise on a regular basis2.
It collects configuration information on demand . OCM can also collect configuration information manually when requested by the user or by Oracle Support2.
Collected configuration information can be uploaded automatically to Oracle (E). OCM can upload the collected configuration information to My Oracle Support automatically for analysis and support purposes3.

NEW QUESTION # 43

1. Stabilize the Exadata Rack.
2. Unpack Oracle Exadata Rack.
3. Review the safety guidelines.
4. Let the Exadata acclimatize for 24 hours.
5. Power on Exadata PDU A.
6. Place Exadata in its allocated space.
7. Power on Exadata PDU B.
What is the correct order of these steps?

A. 3,2,6,4,1,7,5
B. 3,2,6,1,4,7,5
C. 4,3,2,6,1,7,5
D. 2,3,4,6,1,7,5
E. 2,6,1,4,3,7,5

Answer: D

NEW QUESTION # 44
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 cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.
C. 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.
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: B

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.
According to Oracle's documentation1, Exadata Secure RDMA Fabric Isolation is a feature that enables strict network isolation for Oracle Real Application Clusters (Oracle RAC) clusters on Exadata Database Machine systems that use RDMA over Converged Ethernet (RoCE). Exadata Secure RDMA Fabric Isolation uses RoCE VLANs to ensure that network packets from one VM cluster cannot be seen by another VM cluster. VLAN tag enforcement is done at the KVM host level, which means that security cannot be bypassed by any software exploits or misconfiguration on the database server VMs1.
Therefore, the statement that is true about how Exadata Secure RDMA Fabric isolation is used in X9M-2 with virtualization enabled is:
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.

NEW QUESTION # 45
You are updating your Exadata X9M-2 Elastic Database Machine with 6 database servers and 12 High Capacity Storage Servers. You will be using patchmgr to apply updates across the entire machine while still maintaining database availability.
Assuming you are driving patchmgr from an external server, which statement is true about the execution phase?

A. patchmgr cannot apply updates in a rolling manner, you must manually apply patches with the dbnodeudpate and cellupdate tools if high availability is required.
B. patchmgr must be invoked with the -rolling argument. Each component type must be upgraded independently of the other.
C. patchmgr must be invoked with the -rolling argument with all database and storage servers listed in a single input file.
D. patchmgr will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption.

Answer: D

Explanation:
According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book [1], patchmgr can be used to apply updates in a rolling manner while still maintaining database availability. It will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption. This is done by invoking patchmgr with the -rolling argument and specifying the component groups in the input file.
