IBM WebSphere Application Server Network Deployment V8.5 Core Administration Sample Questions:

1. A system administrator is moving the deployment manager from the physical server to the virtualized environment. The system is exported as a virtual image from the current setup, however extra configuration changes are necessary to adjust the environment to the new data center. What change will require extra setup by the system administrator?

A) Change the hostname
B) Change the IP address
C) Increase the available memory
D) Decrease the number of available cores

2. A new security requirement needs to be implemented in the WebSphere Application Server environment. Any application deployed to the WebSphere Application Server cannot have a direct access to the file system if it is not needed. What should the system administrator do to enforce this requirement?

A) Add the 'com.ibm.jvm.filesystemaccess=no' parameter to the WebSphere Application Server configuration file.
B) Modify the JVM policy file located inthe Java SDK directory.
C) Enable Java 2 Security and modify policy files.
D) Add the '-nofs ' option to the JVM startup parameters.

3. A system administrator manages a WebSphere Application Server environment which uses a Federated Repository consisting ofmultiple LDAP servers. The first LDAP server is the corporate, highly-available LDAP server and contains most of the users. The second LDAP server contains only the administrative users and is run on a local system which is restarted regularly. To maximize the availability of the Federated Repository, what should the system administrator do?

A) Add both LDAP servers to the High Availability Manager's core group.
B) Set the second LDAP server as a backup server.
C) Use a TAI (Trust Association Interceptor)to aggregate the LDAP servers.
D) Enable Allow operations if some of the repositories are down.

4. A system administrator needs to define an alternate security configuration for one of the clusters in a cell. As a whole, the cell uses a Federated Repository. The cluster in question needs to define a specific stand-alone LDAP server. How could the system administrator accomplish these requirements?

A) Install and configure a TAI(Trust Association Interceptor) which disables authentication calls coming in just for the cluster.
B) Create a new security domain mapped to a scope of the cluster. Then assign the security attributes for the User Realm to use the stand-alone LDAP server.
C) Use a custom registry which checks with the stand-alone LDAP server for authentication. Ensure that the custom registry is enabled only when calls are made from the cluster.
D) Configure a security domain for the stand-alone LDAP server. Add the applications in the cluster to the security domain.

5. A system administrator is asked to increase the logging level of an e-commerce application running on a production server to help developers troubleshoot a problem that is difficult to reproduce. The requester wants lengthy comprehensive logs to locate the root cause of the problem. The application is responsible for the online shopping experience of thousands of customers daily. The administrator is concerned about degrading performance of the application with the major shopping weekendapproaching. How can the administrator address their performance concerns and satisfy the needs of the developers?

A) Enable High Performance Extensible Logging (HPEL) and disable the HPEL text log.
B) Ask the developers to use the WebSphere Event Logging and redeploy the application.
C) Enable the diagnostic trace service in-memory circular buffer.
D) Enable Cross Component Tracing.
