Oracle Database 10g R2: Administering RAC Sample Questions:

1. After applying a patch to the network device drivers in your operating system, you verify using CRS_STAT-T that everything runs normally. View Exhibitl for the CRS_STAT-T output.
After your coffee break, customers begin complaining about the performance of your Oracle Real Application Clusters database. Suddenly, the response time has increased and establishing new connections is slower than it used to be. You run CRS_STAT-T again to check if there is a problem.
Based on Exhibit2, what is your conclusion, and what would you do to correct this?

A) The second node in your cluster is down and, therefore, CRS has relocated the VIP from the second node to the first node. After you fix the second node, CRS would relocate the relocated VIP back to its original node.
B) There is no problem, so nothing needs to be corrected.
C) You cannot tell what the problem is based on Exhibit2, so you cannot fix this.
D) Somebody relocated the VIP from the second node to the first node for an unknown reason. You just have to relocate it back.
E) The second node in your cluster is down and, therefore, CRS has relocated the VIP from the second node to the first node. After you fix the problem on the second node, you have to relocate the relocated VIP back to its original node using the SRVCTL command.

2. You are asked to design a Maximum Availability Solution for a RAC configuration that provides for continuous availability for the Oracle database and which can survive instance failures, node failures, data failures, and site failures. The RAC configuration has a four-node cluster with five different services configured. Performance must be maintained for any failure situation for all the services, and all data must be preserved. All the servers in the configuration will have the same hardware. Which configuration would you recommend?

A) Asymmetric RAC and a Logical Standby Database in a Dataguard configuration with RAC and ASM at all sites with the same number of instances but different service preferences
B) Asymmetric RAC and a Physical Standby Database in a Dataguard configuration with RAC and ASM at all sites with the same number of instances but different service preferences
C) Symmetric RAC and a Physical Standby Database in a Dataguard configuration with RAC and ASM at all sites with the same number of instances and the same service preferences
D) Asymmetric RAC and Dataguard configuration with a mixture of RAC and single instances using ASM at all sites with the same service preferences

3. What is the action of your client connection when it is using the following connect string? net_service_name= (DESCRIPTION (ADDRESS=(PROTOCOL=tcp)(HOST=sales1 -svr-vip)(PORT=1521)) (ADDRESS=(PROTOCOL=tcp)(HOST=sales2-svr-vip)(PORT=1521))) (CONNECT_DATA=(SERVICE_NAME=sales. us. acme, com)))

A) It tries to connect you to the listener on SALES2-SRV-VIP if the listener on SALES1-SRV-VIP is down.
B) It always connects you to the first protocol address.
C) It randomizes its connection on the available listeners.
D) It always connects you to the least loaded node.

4. You have migrated your 10g R1 cluster to 10g R2. You wish to create multiple copies of the voting disk. What must you consider when doing this?

A) For the voting disk, it is better to rely on multipathing solutions instead of multiplexing.
B) If multiplexing, two voting disks on independent devices is ideal.
C) Since ASM is the stated direction of Oracle, ASM is the best storage for voting disks.
D) If multiplexing, three voting disks on independent devices is ideal.

5. View the Exhibit, which displays the cluster database performance page after the same workload has been executed three times on your cluster without varying any non-Oracle workloads on the cluster. What are the two ways by which you can tell that the corresponding application was better tuned during the second and third execution? (Choose two.)

A) The database throughout graphic is below the red dashed line during the last execution.
B) The run queue length is going down each time.
C) There is less paging each time
D) The number of transactions per second is getting higher each time.
E) It takes less time to execute the workload each time.
