NEW QUESTION NO: 2
The computer where a federated node was running had a failure and cannot be recovered. A system administrator wants to recreate the node with the same configurations in another computer.
Which steps should the administrator execute in order to recover the damaged node?
A. Configure the new computer with a different hostname.
Create a custom profile with the same name.
Federate to the cell using the command addNodewith the default options.
B. Configure the new computer with a different hostname.
Create a custom profile with a different name.
Federate to the cell using the command addNotewith the option -asExistingNode.
C. Configure the new computer with the same hostname.
Create a custom profile with the same name.
Federate to the cell using the command addNotewith the option -asExistingNode.
D. Configure the new computer with the same hostname.
Create a custom profile with the same name.
Federate to the cell using the command addNotewith the options -includeapps.
Answer: C
Explanation/Reference:
You can use the -asExistingNode option of the addNode command to recover and move nodes of a deployment manager. Using the -asExistingNode option, federate a new custom node to a deployment manager as an existing node. During federation, the product uses information in the deployment manager master configuration to transform the custom node into the existing node.

NEW QUESTION NO: 3
The installation of WebSphere Application Server did not complete successfully, and a system administrator needs to troubleshoot the installation.
What can the administrator do to identify the cause of the installation failure?
A. Run the installvercommand with the appropriate command line options.
B. Check the files under the Agent data location of IBM Installation Manager.
C. Check the files under the logsdirectory of IBM Installation Manager installation directory.
D. Check the log.txtunder <WebSphere Application Server install directory><log directory>.
Answer: C
Explanation/Reference:
Installation Manager creates log files that you can use to troubleshoot any installation problems. Consider verifying the log files after any installation to ensure that everything in that process went successfully.
To examine the logs manually, locate the Installation Manager logs directory. The default location for this directory varies according to the operating system:
Windows: C:\ProgramData\IBM\Installation Manager\logs
UNIX: /var/ibm/InstallationManager/logs

NEW QUESTION NO: 4
A system administrator has configured a cluster containing 40 servers. The cluster members all belong to one core group. While examining the log files, the administrator notices that the core group coordinator is consuming abnormally high amounts of memory and CPU resources.
How can the system administrator reduce the memory and CPU resource usage of the core group coordinator?
A. Configure a core group bridge.
B. Configure a second active coordinator.
C. Decrease the memory on the machine.
D. Move the coordinator to another machine.
Answer: B
Explanation/Reference:
Remember that coordinator election occurs whenever the view changes. Electing a new coordinator uses a lot of resources because this process causes increased network traffic and CPU consumption.
Specifying a preferred coordinator server, whenever practical, helps eliminate the need to make frequent coordinator changes.

A system administrator decides to use the advice from the Performance and Diagnostic Advisor to identify the optimum connection pool settings for data sources. In a cell, the data source db2datasource is defined under node scope and used by two servers from that node. The administrator receives two different sets of advice for db2datasource.
One set of advice suggests to increase the maximum connection pool sizefor db2datasource.

How should the administrator configure the data sources before reusing the Performance and Diagnostic Advisor?
A. Create a data source of the same name under cell scope.
B. Create a data source of the same name under server scope for each server.
C. Increase the minimum connection pool sizefor the data source.
D. Decrease the maximum connection pool sizefor the data source.

NEW QUESTION NO: 7
A system administrator runs a Python script that creates and configures several servers and realizes that the script fails before completing. Although many tasks succeeded, they are rolled back when the script fails.
Before running the script again, what can the administrator add to the script after each task so the completed tasks are committed even if other tasks fail?
A. AdminApp.update ()
B. AdminTask.backupJobManager('server')
C. AdminConfig.save()
D. AdminControl.invoke(server, 'sync')
Answer: D
NEW QUESTION NO: 8
Within a WebSphere Application Server Network Deployment cell, a system administrator needs to write a script to determine if a particular server is stopped. It is important that the wsadminscript explicitly return a status of stoppedas opposed to just failing.
What wsadminobject should the administrator use to write this script?
A. AdminApp
B. AdminTask
C. AdminConfig
D. AdminControl
Answer: D
Explanation/Reference:
Use the AdminControl object to invoke operational commands that manage objects for the application server.
Many of the AdminControl commands have multiple signatures so that they can either invoke in a raw mode using parameters that are specified by Java Management Extensions (JMX), or by using strings for parameters. In addition to operational commands, the AdminControl object supports some utility commands for tracing, reconnecting with a server, and converting data types.

A customer has enabled LTPA as their authentication mechanism and has web resources that are not secured by proper security constraints. A system administrator is required to ensure that all web resources are secured.
How should the administrator accomplish this?
A. Enable "Authenticate when any URI is accessed".
B. Enable "Authenticate only when the URI is protected".
Disable "Use available authentication data when an unprotected URI is accessed".
C. Enable "Authenticate only when the URI is protected".
Enable "Use available authentication data when an unprotected URI is accessed".
D. Map the application security roles to the configured user registry's groups.
Answer: A
Explanation/Reference:
Authenticate only when the URI is protected
The application server challenges the web client to provide authentication data when the web client accesses a Uniform Resource Identifier (URI) that is protected by a Java Platform, Enterprise Edition (Java EE) role. The authenticated identity is available only when the web client accesses a protected URI.
This option is the default Java EE web authentication behavior that is also available in previous releases of WebSphere® Application Server.
