Oracle Oracle Certifications 1Z0-134 Questions & Answers

• Question 111:

  You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.

  Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)

  A. AUTO_ACKNOWLEDGE

  B. CLIENT_ACKNOWLEDGE

  C. DUPS_OK_ACKNOWLEDGE

  D. DEFAULT_ACKNOWLEDGE

  Correct Answer: B

  With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge.

  Incorrect Answers:

  A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.

  C: With DUPS_OK_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it; duplicate acknowledges are permitted.

  D: There is no acknowledge mode named DEFAULT_ACKNOWLEDGE.

• Question 112:

  You created a script to monitor your WebLogic Server WLS Execute Thread:

  

  Here is a message in your ExecuteThread.log file:

  

  What is the value of xxxx if the thread has been running a request for twenty minutes, assuming a default configuration?

  A. SRANDBY

  B. ACTIVE

  C. STUCK

  D. RUNNING

  E. WAITING

  F. ADMIN

  G. FAILED

  Correct Answer: C

  This thread is considered Stuck by WebLogic because it's been running for over the time defined in MaxStuckThreadTime (600 seconds by default). Weblogic Server waits for this time to be reached before marking a thread as stuck if the thread is still working after this time.

  Example: [STUCK] ExecuteThread: '2' for queue: 'weblogic.kernel.Default (self-tuning)' id=73 idx=0x128 nid=13410 prio=1 alive, in native, daemon

• Question 113:

  Which two statements are true about the role of cluster master in whole server migration? (Choose two.)

  A. There is exactly one cluster master in the cluster at a given point of time.

  B. The cluster master must host all the pinned services in the cluster.

  C. Any managed server in the cluster can serve as the cluster master.

  D. A cluster master must always be different from a singleton master.

  E. The cluster master must always be started with the node manager.

  Correct Answer: AC

  One server instance in a cluster that contains migratable servers acts as the cluster master and

  orchestrates the process of automatic server migration, in the event of failure.

  Any Managed Server in a cluster can serve as the cluster master, whether it hosts pinned services or not.

  Note: Any server instance in the cluster can serve as the cluster master. When you start a cluster that

  contains migratable servers, the first server to join the cluster becomes the cluster master and starts up the

  cluster manager service. If a cluster does not include at least one migratable server, it does not require a

  cluster master, and the cluster master service does not start up.

• Question 114:

  Examine the domain diagram:

  

  What is the correct path within the configuration hierarchy to the MBean that contains the log rotation parameters for server04? (Choose the best answer.)

  A. /Servers/server04/Log/server04

  B. /server04/log/rotation

  C. /Cluster01/server04/log

  D. /Machine02/server04/log

  E. /Logs/server04

  F. /TestDomain/server04/log

  G. /server04/log

  Correct Answer: A

• Question 115:

  Which two automatic migration scenarios require node manager for all migratable services? (Choose two.)

  A. Consensus leasing

  B. Database leasing with no pre and post migration scripts

  C. Database leasing with pre and post migration scripts

  D. Synchronous leasing

  Correct Answer: AC

  When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:

  *

  Consensus leasing ?Node Manager must be running on every machine hosting managed servers within the cluster.

  *

  Database leasing ?Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required.

• Question 116:

  You are managing and monitoring durable subscribers for your JMS topics to ensure that all the subscribers would receive persistent messages.

  However, JMS connections are currently restricted, so only one connection with the same client ID could exist in the scope of your cluster.

  On which page of the Administration Console can you set Client ID Policy to unrestricted in order to lift this restriction? (Choose the best answer.)

  A. Topic > Monitoring > Durable Subscribers

  B. Connection Factory > Configuration > Client

  C. Topic > Configuration > Thresholds and Quotas

  D. Topic > Configuration > Overrides

  E. Topic > Configuration > Durable Subscribers

  F. JMS Server > Configuration > Durable Subscribers

  Correct Answer: B

  You can find help on Client ID Policy configuration through the following path:

  OTN Home > Oracle WebLogic Server 12.1.1.0 Documentation > Administration Console Online Help > JMS Connection Factory: Configuration: Client

• Question 117:

  Your organization is using a Multi data source (MDS) on WebLogic Server to support applications connecting to an Oracle RAC database. You have been tasked with configuring a new callback handler for the MDS.

  Which two statements are true concerning related MDS options and behavior? (Choose two.)

  A. Callback handlers are optional when using the Failover MDS Algorithm.

  B. If the Failover Callback Handler attribute is set on the MDS, the Test Frequency attribute is no longer used.

  C. Callback handlers are called for both failover and failback decisions.

  D. You can register only one callback handler for each WebLogic server.

  Correct Answer: CD

  C: A callback handler used to control the failover and failback within a multi data source must include an implementation of the weblogic.jdbc.extensions.ConnectionPoolFailoverCallback interface.

  D: You can register a callback handler with WebLogic Server that controls when a multi data source with the Failover algorithm fails over connection requests from one JDBC data source in the multi data source to the next data source in the list.

  Incorrect Answers:

  B: Frequency of these tests is controlled by the Test Frequency Seconds attribute of the multi source. The default value for Test Frequency is 120 seconds, so if you do not specifically set a value for the option, the multi data source will test disabled data sources every 120 seconds.

• Question 118:

  You are asked to configure Node Manager for your production environment. You are considering whether to use the Java version or the script-based version of Node Manager.

  Which statement correctly describes the difference between the two versions?

  A. If you are installing WebLogic Server on a Windows system, you must use the Java version of Node Manager.

  B. The script-based version of Node Manager can be used in conjunction with inetd on supported UNIX systems.

  C. The script-based version of Node Manager requires a larger footprint than the Java version.

  D. When Node Manager is used for consensus leasing, you may see faster performance with the script-based version.

  Correct Answer: A

  Java-based Node Manager runs within a Java Virtual Machine (JVM) process. It is recommended that you run it as a Windows service on Windows platforms and as an operating system service on UNIX platforms. For UNIX and Linux systems, WebLogic Server provides a script-based version of Node Manager.

• Question 119:

  My JMS file store size has grown very large and is using up a significant chunk of the disk. I need to reduce the file size during the maintenance window without impacting any relevant information.

  Which utility enables me to do this? (Choose the best answer.)

  A. weblogic.store.Compacter

  B. weblogic.store.Admin

  C. weblogic.store.Reducer

  D. weblogic.file.FileUtil

  Correct Answer: B

  To open the persistent store administration utility from a Java command line, type the following: > java weblogic.store.Admin Here is an example of using the compact command to compact the space occupied by a file store in the

  mystores directory. > storeadmin->compact -dir c:\mystores -tempdir c:\tmp Reference: https://docs.oracle.com/middleware/1212/wls/CNFGD/store.htm#CNFGD275

• Question 120:

  Your WebLogic Server (WLS) environment consists of multiple domains. Which is a true statement about WLS domains? (Choose the best answer.)

  A. Multiple domains can use the same or separate WLS installation while running on the same machine.

  B. Domains require a minimum of one managed server.

  C. Multiple domains require separate WLS installations while running on the same machine.

  D. Multiple domains require individual Node Managers while running on the same machine.

  E. Multiple domains can share the same administration server.

  Correct Answer: A

  You can use a single Oracle WebLogic Server installation to create and run multiple domains, or you can use multiple installations to run a single domain.

  Incorrect Answers:

  B: Domains include a special WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain. Usually, you configure a domain to include additional WebLogic Server instances called Managed Servers.

  C: A single WLS installation can have multiple domains.

  

  D: By specifying multiple domains in the nodemanager.domains file, you can configure a single, machine-scoped Node Manager process which manages server instances belonging to multiple WebLogic domains.

  E: Each domain requires its own Administration Server for performing management activities.
