Q1. A node isevicted from a three-node cluster due to poor latency of the underlying storage Which two statements arecorrectin describing the instancerecovery process?
A. Perform a restore of archive redo from flashrecovery area to recover database
B. Upon startup, the SMON/LMS processes perform instance crash recovery.
C. Upon startup of failed instance,the SMON process performs instance crash recovery by using checkpoints to determine which data needs to be append to data files.
D. User intervention is not required.
E. Upon startup, PMON (process monitor) performs instance crashrecovery automatically User intervention is not required
Q2. Which statement about ACFS and ADVM under Flex ASM is incorrect?
A. ADVM proxy instance is required for ADVM and ACFS to connect to flex ASM.
B. An ADVM proxy instance must run on the same node as ADVM and ACFS.
C. The ADVM proxy instance is configured on all Hub and Leaf nodes in a Flex cluster.
D. The ADVM proxy instance has its ORACLE_SID set to +APX<node number>.
E. Administrators can shut down the ADVM proxy if ACFS is not running on the node.
Q3. How many ASM Disk Group(s) do you need, if you want to have the redundancy level set to high (triple mirroring) for a FILE?
D. It depends on the number of different disks in a Disk Group, not the number of Disk
Q4. Identify two correct statements about stopping instances and Oracle RAC databases
A. To shut down an Oracle RAC database completely, you must shut down every instance that has the database open or mounted.
B. After a NORMAL or IMMEDIATE shutdown, instance recovery is required
C. srvctl stop instance shuts down the Oracle RAC database.
D. crsctl stop crs stops the stack on the node, including the database instance.
Q5. Which three statements about Oracle RAC background processes are correct?
A. 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
B. 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
C. LMON (Global Enqueue Service Monitor) monitors global enqueues and resources across the cluster and performs global enqueue recovery operations
D. LMD (Global Enqueue Service Daemon) manages incoming remote resource requests withineach instance
E. LMS (Global Cache Service Process) manages non-Cache Fusion resource requests such as library and row cache requests
F. LCKO (Instance Enqueue Process) manages background slave process creation and communication on remote instances
Q6. You want to convert an Oracle Clusterware Standard Cluster to an Oracle Flex Cluster. Which commands will you execute?
A)crsct1 config gns crsct1 add gns –vip myvip| IP address srvct1 stop cluster –node mynode srvct1 modify cluster node flex
B)srvct1 get cluster mode status # if GNS not configured then must be configured with a fixed VIP – find GNS status srvct1 set config gns srvct convert cluster mode flex
C)crsct1 get cluster mode status # if GNS not configured then must be configured with a fixed VIP – find GNS status srvct1 config gns crsct1 set clustermode flex crsct1 stop crs crsct1 start crs -wait
D)crsct1 set clusterware hub crsct1 set clustermode flex
srvct1 show cluster mode status
A. Option A
B. Option B
C. Option C
D. Option D
Q7. You are talking to the network adminteam about the Interconnect network in Oracle RAC and Clusterware. Which statement about the Private interconnect interface is incorrect?
A. Oracle RAC and Oracle ASM instances use the private interconnect for inter-instance communication.
B. Oracle Clusterware uses the private interconnect to exchange Clusterware-related messages among its nodes.
C. It supports both IPv4 and IPv6.
D. It supports redundant network interfaces for load balancing and high availability.
Q8. You are preparing two Oracle Linux nodes, node1 and node2, for the installation of Oracle Grid Infrastructure, you plan to use the existing Linux users "grid" as Grid Infrastructure software.
What task must be performed before installing the Grid Infrastructure?
A. Change the user "grid' initial login group to "dba"
B. No task must be performed.
C. Change the user ID ofthe grid user in node1, node2, or both nodes to guarantee that the user IDs are equal
D. Add "users" to supplementary groups of "grid" in node1. Or, alternatively remove "users" from supplementary groups ofnode2 "grid."
E. Use another Linux user as "grid" might be used for other purposes.
Q9. Which three statements best describe how Oracle ACFS takes advantage of Oracle ASM?
A. File systems can be dynamically resized.
B. Performance can be maximized through direct access to Oracle ASM disk groups.
C. Oracle ACFS maximizes availability through a dedicated path on the Cluster Interconnect.
D. Data reliability in Oracle ACFS is enhanced by Oracle ASM mirroring.
E. All file systems are mirrored across Oracle ASM Disk Groups to increase reliability.
Q10. A customeris using thepolicy-managed database by name RACDB on a 4-node cluster. The server namesinthe Clusterare:dasher, vixen, comet, and dancer
There are two server pools defined, frontoffice and backoffice The attributes are as followsServerpoolmportance MinMax
There are two uniform services being created, crmsrv and hrsrv.
crmsrv is being assigned toserverpoolfrontoffice and hrsrv is assigned to backoffice.
Currently, allfour nodes are up and running. The database and its services are running as follows:
The serverpoolfrontoffice , which is running thecrmsrv service is being run on the dasher and vixen hosts
Theserverpoolbackoffice, whichis runninghrsvc service is being run on comet and dancer hosts.
What happens when the dasher node fails?
A. Nothing happens because any service relocation is a major interruption to the clients who are connecting to the services.
B. One of the nodes is moved from the backofficeserverpool to the fronofficeserverpool . This is moved with the consideration or importance and minimum attributes configured. Effectively, the crmsrv service wil run intwo nodes andhrsvc will run in one node.
C. Rebootlescrs cluster stack willbe tried inallthe duster nodes to resolve the issue.If this is notresolved, allnodes in thecluster get bounced to resolve the issues
D. Because the crmsrv serviceis defined asuniform servicethe cluster ensures at least one node is up and running, which is the current case. So, there will be no service relocation thatwillhappen.
