Q42. Consider the following sequence of CELLCLI commands and SQL statements: 

All CELLCLI commands and SQL statements are executed successfully without warnings. 

Which statement is true about the I/O performance of the DATA01 ASM diskgroups? 

A. The DATA01 diskgroups has better performance because the DATA01 griddisks were created first. 

B. The DATA02 ASM diskgroup has better performance because the DATA02 diskgroups was created first. 

C. The DATA01 diskgroup has better performance because the DATA01 griddisks are created on interleaved cell disks. 

D. The performance of both diskgroups is balanced because they are created on interleaved 

griddisks.

Q47. You are planning the physical installation of two full rack Database Machines and two full-rack expansion racks. The four racks will be combined into one multi rack system. 

Which are the two guidelines for installing this configuration in your data Center? 

A. All Database Machines must be placed side by side with no space between them. 

B. All Expansion Racks must be placed side by side with no space between them. 

C. All racks must be placed in such away that the exhaust air of one rack does not enter theairinlet of another 

D. All racks must be placed side by side with no space between them. 

E. All racks must be isolated from each other with at least one meter between them. 

F. Racks may be placed as required in the machine room. 

G. Expansion Racks must be placed side by side at least one meter apart. 

Answer: AC


Q48. You are in the planning stage of the network configuration for your Database Machine. The requirements are: 

1. A fault-tolerant network, providing higher availability for connections to database instances 

2. Fault tolerance providing higher availability for connections to perform management functions on the database and storage servers. 

3. Full monitoring of all Database Machine components using Enterprise Manager 

Which three components require external Ethernet network cables to connect your existing network infrastructure to your database machine to satisfy this requirement? 

A. Database servers 

B. Exadata storage servers 

C. InfiniBand storage servers. 

D. Power distribution units (PDUs) 

E. Cisco Ethernet switch 

Answer: ABC 


Q49. Which two are true about Exadata storage server alerts? 

A. Metric alerts are never stateful. 

B. Metrics have no thresholds set on them by default. 

C. SNMP alert notifications can be sent to only one destination. 

D. Metric threshold; if set, will persist across storage server reboots. 

E. SMTP alert notifications must be sent to both ASR manager and Enterprise Manager Agents 

Answer: DE 


Q50. Which is true regarding Enterprise Manager monitoring and configuration? 

A. Agents must be deployed on the- storage servers, in case all the database servers are down. 

B. Monitoring the power distribution units (PDUs) is done by Enterprise Manager agents, but additional ethernet cables are required to connect the PDUs to the internal network switch in the Database Machine 

C. Monitoring the power distribution units (PDUs) is done by Enterprise Manager agents without, any additional network configuration. 

D. Agents may be deployed on the storage servers, in case all the database servers are down.
