NEW QUESTION 1
An administrator configures an IBM DB2data source at cell scope. The environment variable DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope. The data source test connection on one node succeeds, but fails on the other node with java.lang.ClassNotFoundException:com.ibm.db2.jcc.DB2ConnectionPoolDataSource.
Which of the below is the likely cause for the exception?

• A. The data source is configured at cell scope.
• B. Multiple driver JARs are installed on the second node.
• C. DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope.
• D. A different version of the JDBC driver JAR does not exist on the second node.

Answer: C

Explanation:
Check that the variable is correctly defined at the scope where the JDBCProvider/DataSource is defined.
Note: At runtime, WebSphere Application Server invokes a physical data source by resolving the appropriate variable at a level where one of thefollowing criteria exists: The scope of the variable can contain the data source configuration; that is, the variable has the larger scope.
The variable and the data source have identical scopes.
Application Server meets these conditions by attempting to resolve the variable at each level of the scope spectrum. That is, the product tries to resolve the variable in the server scope, then the cluster scope, then the node scope, and lastly the cell scope.

NEW QUESTION 2
What is one of the benefits of using a federated repository over a user registry?

• A. Does notsupport identity profiles
• B. Supports only one registry in a realm
• C. Supports multiple registries within a realm
• D. Provides account and password policy support

Answer: C

Explanation:
Federated repositories enable you to use multiple repositories with WebSphere® Application Server. These repositories, which can be file-based repositories, LDAP repositories, or a sub-tree of an LDAP repository, are defined and theoretically combined under a single realm. All of the user repositories that are configured under the federated repository functionality are invisible to WebSphere Application Server.

• A. Repositories must be local.
• B. Repositories must be online.
• C. Repositories can be either local or online.
• D. Repositories are only in the media package.

Answer: C

Explanation:
IBM Installation Manager is a single installation program that can use remote or local software repositories to install,modify, or update certain IBM products. It determines and shows available packages, checks prerequisites and interdependencies, and installs or modifies the selected packages. You also use IBM Installation Manager to uninstall the packages that it installed.

NEW QUESTION 4
Through what protocol can a Java client directly access EJBs running on an application server?

• A. JDBC
• B. RMI/IIOP
• C. SOAP/JMS
• D. SOAP/HTTP

Answer: D

Explanation:
Provided that it uses the correct protocols (SOAP, HTTP, WSDL), any web service client can access a stateless session bean, whether ornot the client is written in the Java programming language. The client doesn’t even “know” what technology implements the service: stateless session bean, JAX-WS, or some other technology. In addition, enterprise beans and web components can be clients ofweb services. This flexibility enables you to integrate Java EE applications with web services.

NEW QUESTION 9
What does the following JVM argument do?
-Xverbosegclog:${SERVER_LOG_ROOT}/verbose.m%d.7/18/16M%S.%pid.txt,20,10000

• A. It changes the default values for verbosegc logging.
• B. It changes the default location of the verbosegc logging.
• C. It configured verbosegc logging once it has already been enabled.
• D. It sets the default value for enabling and configuring verbosegc logging.

Answer: B

Explanation:
-Xverbosegclog[: <file> [,<X>,<Y>]]
Causes -verbose:gc output to be written to the specified file.
If it cannot create the file (for example, if an invalid filename is passed into the command), it will redirect the output to stderr.
If you specify <X>and <Y> the -verbose:gc output is redirected to <X> files, each containing <Y> GC cycles.
The dump agent tokens can be used in the filename. See Dump agent tokens for more information. If you do not specify <file>, verbosegc.%Y%m%d.%H%M%S.%pid.txt is used. example: -Xverbosegclog:newgclogname.log,7,10000

NEW QUESTION 15
Which type of fix would typically be downloaded to address a specific problem?

• A. Interim fix
• B. Cumulative fix
• C. Product fix pack
• D. Cumulative interim fix

Answer: A

Explanation:
A WebSphere Commerce interim fix (iFix) is a software patch that contains fixes for one or more APARs. A WebSphere Commerce cumulative iFix is a comprehensive collection of interim fixes for a specific release. Both types of fixes are installed with theWebSphere Commerce Update Installer (UPDI).
Note: An Authorized Program Analysis Report, or APAR, is a formal report from IBM development to customers that have notified IBM of a problem or suspected defect. If IBM development is able to confirm the existence of the issue they will create an APAR with any known work around and perhaps an indication of which future release, if any, of the IBM program they intend to target for a formal fix to the defect and whether or not a Program Temporary Fix (PTF) is planned. The APAR will then be published so that it is visible to supported customers.

NEW QUESTION 16
An administrator noticed that one of the servers in the core group is experiencing OutOfMemory. As a result, other servers in the core group failed to start.
What core group custom property should the administrator tune to prevent the affected server from impacting other servers in the core group?

• A. IBM_CS_OOM_ACTION
• B. IBM_CS_DATASTACK_MEG
• C. IBM_CS_WIRE_FORMAT_VERSION
• D. IBM_CS_HAM_PROTOCOL_VERSION

Answer: A

Explanation:
IBM_CS_OOM_ACTION
Use this custom property to explicitly enable exception handlers that are specific for OutOfMemoryExceptions that occur when sending or receiving network messages. When this property is set to Isolate, if an OutOfMemoryException occurs when a network message is being sent or received, these exception handlers stop High Availability Manager communications to the Out of Memory process.
If IBM_CS_OOM_ACTION=Isolate is not added to the configuration settings for a core group, if a core group process runs out of memory, the Out of memory process might not
be able to respond to all messages. This situation prevents multi-step protocols from completing, and prevents the starting server from receiving its initial view of the distributed state.

NEW QUESTION 19
When deploying a new edition of an application, which edition rollout configuration option should be used to ensure that the two editions of the application are not active at the same
time?

• A. Atomic
• B. Grouped
• C. Soft reset
• D. Hard reset

Answer: A

Explanation:
Performing an atomic rollout to an edition replaces an edition on half of the cluster at a time to serve all user requests with a consistent edition of the application. All user requests are served by either the previous or the new edition; user requests are never served by both editions.
An atomic rollout ensures that all application requests are served by a consistent edition, for example, either edition 1.0 or 2.0, but not by both.
