Your organization needs a new Oracle 12cR1 RAC environment. The decision is made to done asting RAC system to new servers using theclone.plmethod.Which mandatorystep must be performed before launching the clone procedure?

A. Copy the clone.pl utility to each target node

B. Keep all target nodes network isolated until the cloning is finished on the first node and then join each to the cluster network.

C. Ensure that theserver meets all of the prerequisite requirements because the perlclone.plcloning method does not check that.

D. Install an Oracle 12cR1 Database home to use as a seeded environment.

問題4

You are building a new 12c cluster to accommodate the upcoming projects.You arecurrently working with the networkadmin team to define the requirementsneeded. Currently, thenetworkteam wouldlike to get cleared on the protocols beingused by the various network interface needed. Which three statements about Clusterware communication are correct?

A. For the private network, the interface must support the user datagram protocol (UDP) using high speed network adapters and switches that support TCP/IP. This holds true inthe Linux/Unix environment.

B. For the private network,thenetworkadapters must use high-speed network adapters and switches that support TCP/IP. This requirement holds true inthe Microsoft Windows environment

C. For the public network, each network adapter must support TCP/IP. This requirement holds true for both Microsoft Windows and Linux/Unix environments

D. For the publicnetwork, each network adapter needs tosupport only UDP, which provides lowlatency.This requirement holds true for both MicrosoftWindows and Linux/Unixenvironments

E. There is no mandatory requirement for the protocol being supported for bothprivate and public interfaces.Oracle RAC andClusterware aulomatically detect and support any current standard industry protocol

正確答案: A,B,C

問題5

B. You can issue any command, as long as you are using the force option.

C. You can mount the disk group on all the nodes.

D. You know that nobody is using the disk group, so you can perform a fast rebalancing on the disk group.

E. You can open the database located on this disk group only in standalone mode.

C. Within the Grid Infrastructure home as a file-based repository

D. On a nodeoutside thecluster to guard againstcluster failure

E. In its own single instance Oracle Database 12cR1database and managed as a failover database

正確答案: E
