Oracle Real Application Clusters 12c Essentials - 1z0-432 Exam Questions [2026]

QUESTION NO: 1
You have completed a rolling conversion fromDNS to GNScluster resolution from the database andcluster resources end.The remaining are the configuration changes to be done from theclient side.
Which two items need to betaken into account to achieve a successful connection?

A. All the nodes in the cluster need to be bounced oneafter the otherinorder for the changes to be completed as it is not possible to do it online B. There is no need to change anything in client configuration as the combination of TAF and ONSwillautomatically take care of reaching the correct nodes C. For each client using a SCAN, change the SCAN theclient uses so that theclient uses the SCAN in the domain delegated to GNS D. For each client using VIP names, change the VIP name on eachclient sothat they use the same server VIP name, but with the domain namein thedomain delegated to GNS.

Correct Answer: C,D

QUESTION NO: 2
Which three statements about Oracle RAC background processes are correct?

A. GTXO-j (Global Transaction Process) controls the flow of messages to remote instances, manages global data block access,and transmits block images between the buffer caches or different instances B. LMS (Global Cache Service Process) manages non-Cache Fusion resource requests such as library and row cache requests C. LCKO (Instance Enqueue Process) manages background slave process creation and communication on remote instances D. LMON (Global Enqueue Service Monitor) monitors global enqueues and resources across the cluster and performs global enqueue recovery operations E. LMD (Global Enqueue Service Daemon) manages incoming remote resource requests withineach instance F. ACMS (AtomicControlfile to Memory Service) is an agent that contributes to ensuring that a distributed SGA memory updateis either globally committedon success or globally aborted if a failure occurs

Correct Answer: D,E,F

QUESTION NO: 3
Which statement about the server Flex ASMis incorrect?

A. When an ASM instance fails, the database clients and ASM cluster file systems can reconnect another ASM instance. B. Flex ASM allows ASMclients to remotely connect to ASM over a network. C. Flex ASM requires an ASM instance on each cluster node running an Oracle Database instance D. WithFlex ASM ,a small pool of ASM instances can be used to serve a larger pool of database servers.

Correct Answer: C

QUESTION NO: 4
Which three statements accurately describe the components of the Cluster Ready Services Technology Stack?

A. Cluster Synchronization Services (CSS):Manages the cluster configuration by controlling which nodes are members of the cluster and by notifying members when a node joins or leaves the cluster B. Oracle Agent (oraagent): This process was known as RACG in Oracle Clusterware 11gR1 (11.1). C. Event Management (EVM). Provides time managementinacluster for Orade Clusterware D. Cluster Ready Services(CRS):Aspecialized oraagent process that helps CRSD manage resources owned by rootsuch as the network, and theGrid virtual IP address E. Grid Naming Service (GNS):Handles requests sent by external DNS servers, performing name resolution fornames defined by the cluster. F. Cluster Time Synchronization Service (CTSS): A background process that publishes events that Oracle Clusterware creates.

Correct Answer: A,B,E

QUESTION NO: 5
If you upgrade to ASM 12cR1 and implement Flex ASM, do you need to upgrade all the databases to 12cR1?

A. No.You can run in a mixed 11.2 database instance and a 12cR1 database instance.The
11.2 instance will use the Flex ASM instance of the other server. B. Yes.Allthe databases need to be upgraded to 12cR1 C. No.You can run in a mixed 11.2 database instance and a 12cR1 database instance, but the 11.2 instance willfail if the local Flex ASM instanceis moved to another server D. No.You cannot upgrade your database instance to 12cR1

Correct Answer: C

QUESTION NO: 6
You are given the task of managing an Oracle RAC 12cR1 Cluster by using Oracle Flex ASM.Which two statements are valid?

A. A failure of an ASM instance affects availability for the databases using ASM disk groups due to decreased cardinality of available ASM instances B. When deployed,Oracle Flex ASM enables an Oracle ASM instance to run on a separate physical server from the database server C. To determine whether Oracle Flex ASMis enabled, use asmcmdshowclustermode D. A failure of an ASM instance affects the databases, evenif youare using ASM disk groups

Correct Answer: B,D
