Question 1

After installing an enhanced EAR in a WebSphere Application Server environment, a system administrator with Configurator privileges is able to see a JDBC provider and a data source in the Integrated Solution Console (ISC) but is not able to delete these resources.

How can the administrator resolve this issue?

AUse the AdminTask object to delete the resources.

BStop all application server instances and then delete the resources.

CAsk another administrator with iscadmin privilege to delete the resource.

DEdit the EAR to remove the application scoped resources and reinstall the application.

Answer : A

The JDBCProviderManagement command group for the AdminTask object includes the following commands:

Question 2

The administrator needs to identify any security role references and security constraints in a web application.

How can the administrator identify these roles and constraints?

Aibm-application-ext.xml file using a text editor.

Bibmconfig folder in the application after using the EARExpander command.

CWeb deployment descriptor using IBM Assembly and Deploy Tools.

DSecurity role to user/group mapping by using the Integrated Solutions Console (ISC).

Answer : C

Securing web applications using an assembly tool.

You can use three types of web login authentication mechanisms to configure a web application: basic authentication, form-based authentication and client certificate-based authentication. Protect web resources in a web application by assigning security roles to those resources.

Question 3

A system administrator needs to configure a JDBC provider and a data source for an application in a clustered environment. The administrator also needs to copy the JDBC drivers from the database server to the application server machines.

How can the administrator meet these requirements?

ACreate a JDBC provider and the data source in the cluster scope.Copy the driver to all nodes.Set the environment variable at the node level to the driver's path.

BCreate a JDBC provider in the server scope and the data source in the node scope.Copy the driver to all application servers.Set the environment variable at the node level to the driver's path.

CCreate a JDBC provider in the node scope and the data source in the cell scope.Copy the driver to the deployment manager.Set the environment variable at the server level to point to the deployment manager path.

DCreate a JDBC provider in the application scope and the data source in the server scope.Copy the driver to all application server directories.Set the environment variable in each JVM to the driver's path.

Answer : A

Question 4

A system administrator ran the backupConfig command to backup the configuration using the --nostop option. The administrator changed the properties for the service integration environment by modifying the sib.properties file. During testing the administrator noticed Service Integration Bus related errors and wanted to restore the service integration environment. The administrator used the restoreConfig command, but the tuning properties for the service integration environment were not restore.

How can the administrator prevent this issue?

AUse full repository checkpoint for both the backup and the restore.

BUse the restoreConfig command with --nostop for the restore.

CUse the manageprofiles command for both the backup and the restore.

DUse the backupConfig command without --nostop for the backup

EUse the restoreConfig command without --nostop for the restore.

Answer : A

With the repository checkpoint and restore function, you can back up copies of files from the master configuration repository. You can use the backups to restore the configuration to a previous state if future configuration changes cause operational problems. By using this function, you can reduce recovery time for problems that are caused by configuration changes. Studies of unplanned outages have shown that as much as 36 percent of unplanned outages are due to operator errors. A common source of operator error is a bad configuration change. The ability to quickly undo a bad configuration change is critical to minimizing the outage window.

Question 5

While coordinating a flexible management topology, the job manager can send commands to which components?

AApplication server and name server.

BOn demand router and load balancer.

CDeployment manager and admin agent.

DNode agent and web administration server.

Answer : C

To manage multiple cells, register deployment managers with job manager directly

Use administrative agent to register base server profiles with a job manager

Question 6

In a test environment, a system administrator has configured an external HTTP server in the DMZ that is routing to a cluster of application servers. The administrator wants to achieve higher performance when routing and prioritizing incoming requests to the back-end cluster.

How can the system administrator achieve this task?

AConfigure a cluster of external HTTP servers.

BEnable the prefer local option on the cluster members.

CSet up a Caching Proxy server between the external web server and the application server.

DPlace an On Demand Router (ODR) between the external web server and the application servers.

Answer : D

Question 7

An organization updated their LDAP directories and modified user roles. The roles that were configured to have access to a highly secured enterprise application were deleted and new roles with new names were created. The application then had security related exceptions.

How can a system administrator resolve the exceptions and restore security for the application?

AModify the mapping of security roles of the application to the new LDAP roles.

BModify the application and remove all security constraints and redeploy the application.

CModify the application to have a runAs role for each new LDAP role and redeploy the application.

DCreate an administrative authorization group with administrator privileges scoped for the application with an administrative group role for the new LDAP roles.
