Oracle 1Z0-134 Online Questions & Answers

• Question 1:

  You want to use the WebLogic Diagnostic Framework (WLDF) to monitor some historic MBean attribute values in your WebLogic domain.

  

  Which WLDF component do you use to accomplish this? (Choose the best answer.)

  A. the Harvester with a metric collection definition
  B. a Watch on a metric collection definition
  C. the MBean Collector with a metric collection definition
  D. the Archiver with a metric collection definition
  D. the Archiver with a metric collection definition

  ---

  The Archive component of the WebLogic Diagnostics Framework (WLDF) captures and persists all data events, log records, and metrics collected by WLDF from server instances and applications running on them.

  The Archive provides access interfaces so that the Accessor may expose any of the persisted historical data including logged event data and persisted metrics. Incorrect Answers:

  A: The Harvester component of the WebLogic Diagnostics Framework (WLDF) gathers metrics from attributes on qualified MBeans that are instantiated in a running server. The Harvester can collect metrics from WebLogic Server MBeans and from custom MBeans.

  B: The Watch and Notification component of the WebLogic Diagnostics Framework (WLDF) provides the means for monitoring server and application states and then sending notifications based on criteria set in the watches.

• Question 2:

  As the WebLogic domain administrator, you have been asked to create a new cluster and to establish load balancing of JMS destinations across multiple servers for this cluster. Which three configuration options will ensure load balancing of distributed destinations? (Choose three.)

  A. configuring a JMS server and targeting a WebLogic cluster
  B. configuring multiple JMS servers and targeting them to a WebLogic cluster
  C. configuring multiple JMS servers and targeting them to the configured WebLogic Servers
  D. configuring multiple JMS servers and targeting them to a set of migratable targets
  E. configuring a JMS server and targeting it to a set of migratable targets
  B. configuring multiple JMS servers and targeting them to a WebLogic cluster
  D. configuring multiple JMS servers and targeting them to a set of migratable targets
  E. configuring a JMS server and targeting it to a set of migratable targets

• Question 3:

  Poor ventilation and cooling in and around the machine that hosts your administration server and a clustered managed server causes a local hard drive failure and thus both servers crash as well.

  This is the first time this crash has occurred in production but an automatic Whole Server Migration kicks in as expected. The clustered server migrates to a machine on which it has never run before, and for that reason the server cannot be

  started on this new machine.

  Which action could have helped to launch this migrated clustered server? (Choose the best answer.)

  A. Shut down and relaunch the Node Manager.
  B. Ensure that the Administration Server is up when the server migration is being performed.
  C. First restart the Administration Server, remove this managed server from the cluster, restart it manually, and then target it back to the cluster.
  D. Use a shared disk/NFS for all the migratable servers in the cluster.
  E. Copy the Node Manager security files to the new machine that hosts your migrated server.
  D. Use a shared disk/NFS for all the migratable servers in the cluster.

  ---

  There is no built-in mechanism for transferring files that a server depends on between machines. Using a disk that is accessible from all machines is the preferred way to ensure file availability. If you cannot share disks between servers, you must ensure that the contents of domain_dir/bin are copied to each machine.

• Question 4:

  You are monitoring a WebLogic JDBC data source and have decided to drop some connections because an earlier peak usage condition has now ended. In addition, this data source has not been enabled for automatic shrinking. What will occur once you execute the shrink() method on that JDBCDataSourceRuntimeMBean?

  A. The number of connections in the pool will be reduced to the greater of either the current number of connections in use or to the minCapacity property setting.
  B. The number of connections in the pool will be reduced to the current number of connections in use regardless of the minCapacity property setting.
  C. The number of connections in the pool will be reduced to the minCapacity property setting regardless of the current number of connections in use.
  D. The number of unused connections in the pool will be reduced by half.
  A. The number of connections in the pool will be reduced to the greater of either the current number of connections in use or to the minCapacity property setting.

  ---

  When you shrink a data source, WebLogic Server reduces the number of connections in the pool to the greater of either the initial capacity or the number of connections currently in use. Reference: https://docs.oracle.com/cd/E13222_01/wls/docs92/jdbc_admin/manage.html#wp1048129

• Question 5:

  One server in your WebLogic domain is experiencing a problem. You want to use the WebLogic Diagnostic Framework (WLDF) to diagnose the problem. The default built-in WLDF module is currently configured on the server, but it does not

  capture the metrics you need.

  You have the following requirements:

  You do not want to delete the existing module.

  You want to minimize metric data output while troubleshooting the issue.

  You want to focus your analysis on only the server that is experiencing the problem.

  What WLDF configuration would achieve this result? (Choose the best answer.)

  A. Create a new module and add metrics to it, target the new module to the server with the problem, and then activate the new module alongside the existing module.
  B. Deactivate the existing module, create a new module and add metrics to it, set an instance parameter to the server with the problem, and then activate the new module.
  C. Deactivate the existing module, create a new module and add metrics to it, target the new module to the cluster with the problem, and then activate the new module.
  D. Deactivate the existing module, create a new module and add metrics to it, target the new module to the server with the problem, and then activate the new module.
  A. Create a new module and add metrics to it, target the new module to the server with the problem, and then activate the new module alongside the existing module.

• Question 6:

  Which three tools allow you to create a Domain Template? (Choose three.)

  A. JDeveloper
  B. pack command
  C. Smart Template Wizard
  D. weblogic.Build
  E. Domain Template Builder
  F. WLST
  G. Archive command
  B. pack command
  E. Domain Template Builder
  F. WLST

• Question 7:

  You are troubleshooting an application that uses a WebLogic server data source. You decide to execute a reset() operation on the corresponding JDBCDataSourceRuntimeMBean. Which statement is true regarding the impact on the application that is using that data source? (Choose the best answer.)

  A. A Reset is the equivalent of a Shutdown followed by a Start.
  B. A Reset is the equivalent of a Force Suspend followed by a Resume.
  C. A Reset is the equivalent of a Suspend followed by a Resume.
  D. A Reset is the equivalent of a Force Shutdown followed by a Start.
  A. A Reset is the equivalent of a Shutdown followed by a Start.

• Question 8:

  On a WebLogic Managed Server you administer, you have the following log:

  

  You investigate and find a Web Module named MyApp with the following deployment descriptor weblogic.xml:

  

  Which two are true? (Choose two.)

  A. Access to Web Module MyApp now returns an HTTP Error: 503 Service unavailable.
  B. The ExecuteThread: `17' is now available because WebLogic Server automatically stops stuck threads.
  C. When the WebLogic Managed Server is restarted the Web Module will be in Admin mode.
  D. If another thread is stuck the error number will be in the WebLogic log file.
  E. The health status of the Managed Server where the application is deployed is now warning due to the subsystem pooltread.
  B. The ExecuteThread: `17' is now available because WebLogic Server automatically stops stuck threads.
  D. If another thread is stuck the error number will be in the WebLogic log file.

• Question 9:

  I want to configure automatic migration of pinned services from an unhealthy server to another target in the cluster. I wish to configure consensus leasing for this purpose. Which two statements are true in this scenario? (Choose two.)

  A. Set the cluster "Migration Basis" policy to Consensus.
  B. Migratable server should be associated with a node manager.
  C. Set the server "Migration Basis" policy to Consensus.
  D. A high availability database must be configured to manage consensus leasing information.
  A. Set the cluster "Migration Basis" policy to Consensus.
  C. Set the server "Migration Basis" policy to Consensus.

  ---

  A: Using the Automatic Migration option requires setting a cluster's Migration Basis policy to either Database or Consensus leasing.

  C: Setting Migration Basis to Consensus leasing means that the member servers maintain leasing information in-memory, which removes the requirement of having a high-availability database to use leasing. This version of leasing requires that you use Node Manager to control servers within the cluster.

• Question 10:

  You are required to configure a Coherence cluster for a WebLogic domain. Review the image below for the architecture of the WebLogic domain.

  

  The configuration represents the following:

  Two WebLogic clusters of n number of servers each One cluster contains an EAR deployment that contains a WAR module and a GAR module One cluster contains a GAR deployment Application data flows into the cluster with the EAR deployment and then to the cluster with the standalone GAR deployment

  Based on this configuration, what is the typical configuration of a Coherence cluster for this domain?

  A. Single Coherence cluster that includes both WebLogic clusters. EAR cluster is storage-disabled. GAR cluster is storage-enabled.
  B. Single Coherence cluster that includes both WebLogic clusters/ EAR cluster is storage-enabled. GAR cluster is storage-disabled.
  C. A Coherence cluster for each WebLogic cluster. EAR and GAR clusters use a replicated topology with storage enabled.
  D. Single Coherence cluster that includes both WebLogic clusters. EAR and standalone GAR clusters are both storage-enabled.
  A. Single Coherence cluster that includes both WebLogic clusters. EAR cluster is storage-disabled. GAR cluster is storage-enabled.

  ---

  A Coherence cluster can contain any number of managed Coherence servers. The servers can be standalone managed servers or can be part of a WebLogic Server cluster that is associated with a Coherence cluster.

  *

  storage-disabled ?a managed Coherence server that is not responsible for storing data and is used to host Coherence applications (cache clients). A Coherence application GAR is packaged within an EAR and deployed on storage-disabled managed Coherence servers.

  *

  storage-enabled ?a managed Coherence server that is responsible for storing data in the cluster. Coherence applications are packaged as Grid ARchives (GAR) and deployed on storage-enabled managed Coherence servers.
