- BConfigure a DMZ secure proxy.
- CConfigure High Performance Extensible Logging.
- DConfigure primary and backup load balancers for the HTTP servers.
5454. 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.

5555. While monitoring a cluster in the cell, the administrator notices that one server in the cluster periodically loses connections to the database. When this happens, requests to the server have a significantly decreased response time and various error conditions are listed in the log files for the server. Since the error codes are returned quickly, the server starts returning responses faster than the average service times for the application. Due to this, the weight for the server is increased and a large percentage of incoming requests are being routed to the erroneous server and the server is getting overloaded with requests.
How can the administrator detect these conditions in the future and take action to prevent this
problem?- AConfigure the storm drain health policy.
- BConfigure the on demand router (ODR) transport chain to tune inbound connections.
- CMonitor the JVM heap usage to determine a new server weight.
- DEnable the PMI Extended statistic set and use the Connection Pool summary report.

What can the system administrator configure to ensure users can continue to work if one of the cluster server fails?- AAn increased session timeout.
- BA cluster of external HTTP servers.
- CA load balancer to spread work between existing servers.
- DA WebSphere eXtreme Scale HTTP session management.
5757. A developer created an enterprise application which contained data source and security role information. The developer asked a system administrator to install this application to an application server where global security is enabled using the Integrated Solutions Console (ISC). A new data source was configured at the server scope for the use of this application. While load testing the application, the developer noticed that the attributes configured on the new data source were ignored by the application server.
How can the administrator ensure that the attributes configured on the new data source are used by the application server?- ACreate the data source under cell scope instead of server scope.
- BDelete any data source of the same name defined under node, cluster or cell scope.
- CReinstall the application and clear the Process embedded configuration check box.
- DCorrect the component-managed and container-managed authentication aliases set on the data
source.
5858. 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?- AEnable “Authenticate when any URI is accessed”.
- BEnable “Authenticate only when the URI is protected”.
- CEnable “Authenticated only when the URI is protected”.
- DMap the application security roles to the configured user registry’s groups.
- AEnable “Authenticate when any URI is accessed”.
5959. A system administrator wants to learn some of the Python scripting commands for the administration of the environment.
Which product feature should the administrator use?- AThe wsadmin.properties file to load a profile.
- BThe AdminTask object to generate wsadmin scripts.
- CThe guided activities panel from the Integrated Solutions Console (ISC).
- DThe “Log command assistance commands” option in the Integrated Solutions Console (ISC).
6060. A system administrator completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs. The administrator notices that the shared resources directory is very large in size and grows larger each time the Installation Manager is run.
How can the administrator decrease the size and remove some of the content from the shared resources directory?- AManually delete content from the directory.
- BDuring an update, create a new shared resources directory.
- CClear the Delete Saved Files option for the Installation Manager.
- DSet the preserveDownloadedArtifacts preference to false.
6161. A system administrator, Admin1, with Administrator privileges has archived full repository checkpoints. Another administrator, Configurator1, with Configurator privileges has copied the checkpoint contents directory from one of the archived check points to its original location. Configurator1 tries to restore the configuration using the copied archived checkpoint contents and the restore fails.
How can Configurator1 restore the configuration using the copied archived full repository checkpoint?- ACopy the archived checkpoint metadata directory to its original location.
- BIncrease the Automatic checkpoint depth to keep all the delta checkpoints.
- CDelete the delta checkpoints taken after the full repository checkpoint was taken.
- DAsk an administrator to update the privileges for Configurator1 to matchAdmin1.
6262. A system administrator is configuring the security of a new environment. The administrator has been asked to configure one LDAP server that has different sub-trees for business users and administration users.
What should the administrator do to implement the required security configuration?- AInstall and configure a TAI (Trust Association Interceptor)
- BConfigure a security domain for the stand-alone LDAP server.
- CUse Federated repositories and configure the supported entity types.
- DUse Stand-alone custom registry and configure the flat file implementation.
6363. 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.

- 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.

- CCheck the files under the logs directory of IBM Installation Manager installation directory.
- DCheck the log.txt under <WebSphere Application Server install directory><log directory>.

How should the administrator meet this requirement and restrict Configurator role access for a single application?- ACreate a J2C authentication alias for that developer.
- BCreate an Administrative user role and provide Configurator access to the developer.
