Oracle Database 10g R2: Administering RAC 1Z0-048 Prüfungsfragen mit Lösungen

1. Which optional parameter of the DESCRIPTION clause of a TNS entry can you use to make sure that another protocol address is tried if the first one fails?

A) TYPE OF SERVICE
B) LOAD_BALANCE
C) SOURCE_ROUTE
D) FAILOVER

2. Which CREATE SEQUENCE option is the most scalable?

A) NOCACHE NOORDER
B) NOCACHE ORDER
C) CACHE NOORDER
D) CACHE ORDER

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) The workloads of the archive processes on the standby instances would be balanced, thereby allowing load balancing across the cluster where the standby resides.
D) 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.
E) 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.

4. Which optional parameter of the DESCRIPTION clause of a TNS entry can you use to randomize the access to available listeners?

A) TYPE OF SERVICE
B) LOAD_BALANCE
C) SOURCE_ROUTE
D) FAILOVER

5. You are about to build a new Oracle Clusterware-based cluster and you want to make the installation process as smooth as possible. You decide to use the Cluster Verification Utility (CLUVFY) to check whether or not your system administrator has set up the hardware and system software correctly. Which two statements about CLUVFY are true? (Choose two.)

A) You can run CLUVFY only from a privileged operating system account.
B) After the Oracle Clusterware installation, you can run CLUVFY from the Oracle Home that holds the CRS binaries.
C) CLUVFY cannot be used until the Oracle Clusterware is installed successfully.
D) To use CLUVFY during the Oracle Clusterware installation, you have to download CLUVFY from the Oracle Technology Network (OTN) Web site and install it before you can use it.
E) You can run CLUVFY directly from the Oracle Clusterware distribution media.
F) You have to install CLUVFY on all cluster nodes in order to use CLUVFY on other nodes than the one from which you perform the installation.
