IBM Assessment: IBM WebSphere Process Server V7.0, Deployment Sample Questions:

Question 1

A client wants to build a clustered environment in preparation for an unknown number of business processes to be deployed to in the future. Flexibility in the systems' capability is required. The deployment professional has recommended the Remote Messaging and Remote Support topology. Which of the following explains the deployment professional's recommendation?

A. It uses the fewest physical servers.
B. It uses multiple active messaging engines.
C. It has unlimited scalability for messaging.
D. It has the most scaling and performance tuning flexibility.

Question 2

A problem is reported with a deployed business process in the production environment with several of the application target JVMs exhibiting high CPU utilization. The deployment professional has obtained tprof output and javacores of the processes in question. What are the appropriate steps to take to locate the thread or threads which are responsible for the high CPU consumption?

A. Find the thread ID from sleep.prof, convert them to hex code and search for calculated hex code in javacores
B. Find the threads from javacore
C. Find the thread ID from javacore, convert them to hex code and search for calculated hex code in sleep.prof
D. Find the threads from sleep.prof

Question 3

In a clustered WebSphere Process Server (WPS) V7.0.0 environment, a company has migrated several long running business processes from earlier V6.x versions. An application performance issue which was identified in earlier versions was resolved by adjusting the maximum concurrent endpoints parameter of the BPEInternalActivationSpec of the Message Driven Bean (MDB) based on the peak load. However, the long running business processes do not perform as well as before. In spite of adopting similar settings, what has happened in the new WebSphere Process Server V7.0.0 environment and what are the appropriate tuning settings?

A. Modify the JMS connection factory BPECFC connection pool size to number of threads in the BPEInternalActivationSpec plus 10%. This is the required setting in WPS V7.0.0 used when work manager based navigation is enabled.
B. WPS V7.0.0 fix pack one must be installed to enable optimization introduced by the Business Object (BO) Runtime Framework.
C. In WPS V7.0.0, the default for business process navigation is modified to utilize the advanced performance optimizations feature that leverages work manager based navigation. Accordingly, adjust the BPENavigationWorkManager message pool size and the InterTransactionCache size to accommodate the maximum concurrent incoming requests.
D. Modify the sib.msgstore.discardableDataBufferSize and sib.msgstore.cachedDataBufferSizeCachedDataBufferSize for optimal messaging engine (ME) performance.

Question 4

A deployment professional has installed WebSphere Process Server binaries on AIX 5.3 TL7 with 64 bit architecture. Now the deployment professional needs to create a cell with two managed nodes federated to the deployment manager profile. Select the option which is NOT applicable.

A. Select the profile template /profileTemplate/managed.wbiserver.
B. Select the profile template /profileTemplate/dmgr.wbiserver and use manageprofiles script.
C. Create profiles using silent option through manageprofiles script on /WPS_HOME/bin/manageprofiles.
D. Use the Profile Management Tool to create and augment profiles.

Question 5

A highly available WebSphere Process Server clustered environment comprises of cluster1 with two members, clusterMemberA and clusterMemberB. cluster1 has been added as a member of a bus. The two cluster members host a message producer application, App1, and a message consumer application App2 which needs to consume messages produced by App1. App2 must receive messages in a sequential manner maintaining the order of message delivery. During peak load, the clusterMemberA is most active taking significant performance impact while clusterMemberB is almost idle and is only experiencing about 25% of the overall activity. Identify the steps the deployment professional should take to reconfigure the messaging infrastructure so that the load is balanced more evenly among both cluster members of cluster1.

A. Create an additional messaging engine on cluster1 so that each cluster member hosts an active messaging engine for an even load distribution.
B. Create a secondary two member cluster cluster2 with messaging only capabilities. Add cluster2 as a bus member and create an additional active message engine on cluster2 and detach cluster1 from the bus .
C. Create a secondary two member cluster cluster2 with messaging only capabilities. Add cluster2 as a bus member and detach the cluster1 from the bus.
D. Create another server with messaging only capabilities. Add this server as a bus member and detach the cluster1 from the bus.
