Oracle Oracle Certifications 1Z0-133 Questions & Answers

• Question 31:

  Your developers created Plain Old Java Objects (POJO) that provide useful functionality. The code is

  packaged in a JAR file. You want to make this code accessible from all the applications deployed to the

  managed servers in your domain.

  What are the four ways to accomplish this? (Choose four.)

  A. Include the JAR file as an optional package

  B. Deploy the JAR file as an EJB

  C. Deploy the JAR file as a shared library

  D. Place the JAR file in the lib folder of the domain

  E. Deploy the JAR file to the administration server. All managed servers have access to their admin server

  F. Add the JAR file to the CLASSPATH of the domain servers by editing the domain's seyDomainEnv.sh script

  G. Deploy the JAR file as another web application

  H. Deploy the JAR file as a web service.

  Correct Answer: BCEH

• Question 32:

  The admin server's domain files were backed up by using the tar command on Linux. The admin server crashes and the domain files become corrupted. The domain files are restored from the backup. You try and start the admin server by using the usual domain start script. The script does not run. The error is "permission denied". How should you troubleshoot this?

  A. Check the ownership and file system permissions of the start script

  B. Ensure you are currently logged in as a WebLogic Server administrator before running the script

  C. Stop any running managed servers and then start the admin server

  D. After the restoration of a domain, you must start the admin by using WLST

  E. Be sure to start the admin server as the root user

  Correct Answer: A

• Question 33:

  View the following file except, which configures HTTP session replication:

  replicated

  From which file is this except taken?

  A. weblogic-application.xml

  B. session.xml

  C. web.xml

  D. config.xml

  E. weblogic.xml

  Correct Answer: E

• Question 34:

  Your administration server goes down. One of the managed server of the domain is also currently shut down. This managed server has been successfully started in the past. You cannot bring up the administration server right away, but you need to start the managed server. You run the start script, but the managed server will not start. Explain this.

  A. This managed server has disabled Managed Server Independence mode

  B. Managed servers always contact their admin server for the latest configuration. When the admin server is down, a managed server cannot be started.

  C. This managed server must be part of a cluster and the cluster master is also down

  D. This managed server must reside on the same machine as the admin server

  E. The domain must use the embedded LDAP for authentication. Without the admin server, the managed server cannot get updates to its local LDAP store

  Correct Answer: A

• Question 35:

  Select two ways to start the Java-based Node Manager on a Linux machine. (Choose two.)

  A. Use the startNodeManager.sh script

  B. Use the administration console. Select the machine and then click the Start button.

  C. Have Node Manager start at system boot as a daemon

  D. Use the Oracle Process Manager and Notification Server (OPMN) to start Node Manager as a system process

  E. Set the appropriate environment variables. Then run the Java virtual machine with the class nodemanager.RunTime, passing the class the proper parameters.

  Correct Answer: AB

• Question 36:

  One of your applications sends SQL requests to a back-end database. Today some of these requests are very slow to complete and users are waiting an unusually long time before getting the information back. You decided to take a look at a thread dump and found several threads with a stack similar to:

  

  What should be your initial assumption and first action?

  A. The maximum capacity of the connection pool was reached due to higher load than usual and you just need to wait until new connections get released or increase the capacity of the pool. This can be done in the Admin Console.

  B. The response data provided by the database SQL is larger than the receive socket buffer, so you just need to increase the buffer

  C. The activity on the database side needs to be checked with your DBA to verify if the connection request was received and how it's been handled by the database

  D. The datasource connection was leaked and needs to be reset

  E. A firewall is blocking the connection between WebLogic Server and the back-end database. This needs to be immediately addressed with your network administrator

  F. The Oracle JDBC driver got corrupted and needs to be reinstalled or replaces with a different driver

  Correct Answer: B

• Question 37:

  Identify two advantages of using a Single Client Access Name (SCAN) when configuring a GridLink data source. (Choose two.)

  A. The Fast Connection Failover (FCF) pattern, which allows rapid failure detection, is enabled

  B. The more sophisticated runtime connection load balancing (RLCB) is used; without SCAN, load balancing reverts to a simple round-robin scheme

  C. SCAN is required for the GridLink data source to use an XA driver

  D. The database URL is shorter because it contains one SCAN alias and port as opposed to a host and port foe each RAC node

  E. The data source configuration does not need to be updated when new nodes are added to the RAC cluster

  Correct Answer: AE

• Question 38:

  In your WebLogic Server environment, applications will not access a single database server. Instead they will access a cluster of redundant database servers. This database product was purchased from a vendor other than Oracle. You want to provide transparent failover to the applications as they communicate with the database cluster. Which type of WebLogic data source should you create?

  A. generic data source

  B. multi data source

  C. GridLink data source

  D. parallel data source

  Correct Answer: B

• Question 39:

  You create a new dynamic cluster with the following parameters: Number of servers: 2 Listen port: 8101 Enable calculated listen ports: true

  To which two port numbers will the resulting two dynamic servers bind? (Choose two.)

  A. 8101

  B. 8102

  C. 8103

  D. 8100

  E. 8104

  Correct Answer: AD

• Question 40:

  Consider a web application that is deployed to a single cluster. After configuring the application to use in-memory session replication, there is a noticeable drop in performance, possibly due to the large amount of data being placed in HTTP sessions. Which action improves performance while continuing to provide high availability for this application's sessions?

  A. Configure asynchronous session replication in the application

  B. Increase session timeout in the application

  C. Configure file-based session persistence in the application

  D. Configure automatic service migration in the application

  E. Configure cookie-based session persistence in the application

  Correct Answer: C
