Oracle Database 10g R2: Administering RAC Sample Questions:
Question #1
Which four statements contain accurate information regarding RAC VIPs and application VIPs? (Choose four.)
A. It is recommended to share application VIPs among multiple applications.
B. A RAC VIP fails over if the listener fails.
C. It is not recommended to share an application VIP among several applications.
D. It is not recommended to share a RAC VIP among several database instances.
E. A failed over application VIP does accept new connections.
F. An application VIP fails over if the associated application fails over.
G. A failed over RAC VIP does accept new connections.
H. It is recommended to share a RAC VIP among several database instances.
Question #2
You want check whether the group services node application is running on all the nodes in your cluster before you create a cluster database. Which utility can you use to make sure the node application is running on all nodes in the cluster?
A. crs_stat
B. addnode.sh
C. crsctl
D. onsctl
E. Isnrctl
Question #3
View the Exhibit.
A Symmetric RAC and Physical Standby Database configuration is set up for a high availability requirement matching the one in the exhibit with the primary using 'maximum availability' protection mode.
Which two benefits are there for each primary instance in sending its redo to a corresponding standby instance, rather than having all the primary instances sending redo to the same standby apply instance? (Choose two.)
A. If the redo receive load is spread across multiple receiving instances then the primary redo transport is less likely to become a bottleneck.
B. The services on the primary would be symmetric allowing performance on each instance to be equal in the event of a switchover or failover to the standby database.
C. Multiple standby instances allow the redo to be applied more quickly by the standby apply instance after the redo has already arrived from the primary.
D. The workloads of the archive processes on the standby instances would be balanced, thereby allowing load balancing across the cluster where the standby resides.
E. Multiple standby instances allow the redo to be written to standby redo logs more quickly than just using a single receiving instance by reducing commit time on the primary instances.
Question #4
You have attended a user group presentation on RAC and based on what you have learned you feel that your company would benefit from having the RAC option to meet its Oracle database requirements in several ways. Your manager does not know much about RAC and asks you to create a presentation to the team explaining RAC, and whether it should be implemented in your installation. Which three statements explain the benefits and implications of RAC? (Choose three.)
A. RAC would increase availability in the event of a network failure.
B. RAC used in conjunction with parallel execution may provide for speedup of OLTP workload processes.
C. RAC would increase scalability for all application workloads in all cases.
D. RAC used in conjunction with parallel execution may provide speedup of DSS queries.
E. RAC would increase availability in the event of node and instance failures.
F. RAC alone would increase availability when doing release upgrades.
G. RAC alone would not help protect from human errors.
H. RAC would increase availability in the event of data failures.
Question #5
You decide to implement a Data Guard configuration to support a disaster recovery plan for your RAC database. Your primary database has all shared files and the flash recovery area is stored on ASM disk groups. Which three options exist for storing the data guard broker configuration files at the primary location? (Choose three.)
A. must be stored on Oracle Cluster File System if a cluster file system is used
B. can be stored on shared Raw Devices
C. may be stored on any supported cluster file system if a cluster file system is used
D. can be in any shared ASM disk group
E. must be in the same shared ASM disk group as the Flash Recovery Area if the broker configuration files are stored in ASM disk groups.
F. must be in the same shared ASM disk group as the database data files if the broker configuration files are stored in ASM disk groups
