Oracle Exadata Database Machine X8M Implementation Essentials: Common Questions From Candidates

What is the Oracle Exadata Database Machine X8M Implementation Essentials certification exam?

The Oracle Exadata Database Machine X8M Implementation Essentials exam (code: 1z1-902) is the official Oracle exam that leads to the Oracle Engineered Systems certification. It sits at the Specialist level of the Oracle certification track. It is also connected with related credentials such as Oracle Exadata Database Machine X9M Certified Implementation Specialist. Passing it proves to employers that your skills have been validated by Oracle itself, which is why the 1z1-902 credential keeps showing up in job postings.

How many questions are in the 1z1-902 exam, and how long does it take?

The Oracle Exadata Database Machine X8M Implementation Essentials exam gives you 90 minutes to work through 85–87. Pacing matters more than most candidates expect, so before exam day, run at least one full timed session in the Dumpkiller test engine to learn how long you can afford per question. If an item stalls you, flag it and move on — coming back later beats burning five minutes on a single question.

Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions:

Question 1

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 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 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.

Question 2

Which of the following is NOT a requirement when validating, receiving, unpacking, and planning access route and space requirements for Exadata Database Machine?

A. Oracle Exadata Rack may only be installed on raised floor environments.
B. A conditioned space is required to remove the packaging material to reduce particles before entering the data center.
C. All four leveling and stabilizing feet should be raised and out of the way prior to moving the rack.
D. 914mm of space required above the rack height is required for maintenance access.
E. The entire access route to the installation site should be free of raised-pattern flooring that can cause vibration.
F. The incline of any access route ramp must be less than or equal to 6 degrees.

Question 3

Which two options describe the flash memory capabilities of the Exadata X9M-2 database and storage severs?

A. 8 x 6.4 TB NVMe flash cards on the Extreme Flash (EF) storage server
B. 8x 6.4 TB NVMe flash cards on the Extended (XT) storage server
C. No flash storage on the database server
D. 4 x 6.4 TB NVMe flash cards on the database server
E. 4 x 6.4 TB NVMe flash cards on the High Capacity (HC) storage server

Question 4

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?

A. Install Oracle Rest Data Services on each Database server and install the MS APEX application.
B. Install Oracle Rest Data Services on each Storage server and install the MS APEX application.
C. 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.
D. The MS Process on the storage servers is natively endowed with REST services, but are not enabled by default.

5. Automatic Diagnostic Repository Command Interpreter (ADRCI)
6. CELLCLI
7. Cell Server(CELLSRV)
8. diskmon
9. Restart Server (RS)
10. Management Server (MS)
What is the correct location where these software components can run in the standard Exadata Database Machine deployment?

A. 1, 2, 3, 4, 5, 8, 9 and 10 run on the database servers; 5, 6,7, 9 and 10 run on the Exadata storage servers.
B. 1, 2, 3, 4, 9 and 10 run on the database servers; 5, 6, 7, 8, 9, and 10 run on the Exadata storage servers.
C. 1, 2, 3, 4, 8 and 9 run on the database servers; 5, 6, 7, 9 and 10 run on the Exadata storage servers.
D. 3, 4, 8, and 10 run on the database servers; 1, 2, 5, 6, 7 and 9 run on the Exadata storage servers.
