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

1. A lightweight development environment for running a new web application that does not requirethe full Java EE stack has to be built. A system administrator decides to use a Liberty Profile and needs a Liberty Profile runtime to create the server and deploy the new application on it. Which tools could the system administrator use to create the runtime? (choose 2)

A) IBM Installation Manager
B) WebSphere Application Server Developer Tool (WDT)
C) WebSphere Customization Tool
D) Install Verification Tool
E) Profile Management Tool

2. A system administrator needs to view the list of certificates for unmanaged web server located on a remote system. How should the system administrator do this?

A) View the plugin-cfg.xml
B) Use iKeyman to view the keyring.
C) Look at the SSL configuration in the httpd.conf
D) Use the administrative console to check the content of the cell default keystore.

3. An application that uses HTTP Session objects has been deployed on a horizontal cluster. A system administer needs to configure the memory-to-memory session replication so as to maximize the chances of successful session failover. How should the system administrator configure a replication domain?

A) Select single replicaand select the tuning parameter to be optimized for performance
B) Select single replica for the number of replicas.
C) Select entire domain and select the tuning parameter to be optimized for performance.
D) Select entire domain for the number of replicas.

4. A system administrator has deployed web applications to a clustered environment where database session persistence is configured. The administrator needs to improve both the response time and the system load with the application servers. How can the system administrator do this?

A) Enable server affinity.
B) Configure dynamic caching.
C) Tune the database session persistence to optimize for failover.
D) Configure a load balancer to spread work between existing web servers.

5. 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) 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.
B) Configure a security domain for the stand-alone LDAP server. Add the applications in the cluster to the security domain.
C) 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.
D) Install and configure a TAI(Trust Association Interceptor) which disables authentication calls coming in just for the cluster.
