Question 2

Which tool can be used to collect data to be used for monitoring and tuning the environment?

AThread and Monitor Dump Analyzer

BPerformance Monitoring Infrastructure

CIBM Tivoli Performance Viewer Advisor

DGarbage Collection and Memory Visualizer

Answer : B

WebSphere Application Server provides Performance Monitoring Infrastructure (PMI) data to help monitor the overall health of the WebSphere Application Server environment. PMI provides average statistics on WebSphere Application Server resources, application resources, and system metrics. Many statistics are available in WebSphere Application Server, and you might want to understand the ones that most directly measure your site's resources to detect problems.

CThe offering ID must point to the correct instance.

DThe repository location must point to the correct instance.

Answer : D

Question 4

What is the default location for heap dumps?

A/logs

B/profiles/logs

C/logs/server1

Answer : D

Question 5

DThe Job Manager also maintains a master repository for the environment.

Answer : B

Question 7

In an IBM WebSphere Application Server cluster, an administrator notices EJB requests are not evenly distributed on the cluster members during the load test.

What two things can the administrator verify in order to identify and resolve the issue? (Choose two.)

AEnsure Dynamic Workload Management is enabled.

BEnsure host scoped routing optimization is enabled.

CEnsure PMI Workload Management counters are enabled.

DEnsure each server in the cluster has an equal weighted value.

EEnsure the Web server plug-in is using the round robin algorithm.

Answer : A, D

A: Workload management optimizes the distribution of client processing tasks. Incoming work requests are distributed to the application servers, enterprise beans, servlets, and other objects that can most effectively process the requests.

D: The server weighted round robin routing policy ensures a balanced routing distribution based on the set of server weights that have been assigned to the members of a cluster. For example, if all servers in the cluster have the same weight, the expected distribution for the cluster is that all servers receive the same number of requests. If the weights for the servers are not equal, the distribution mechanism sends more requests to the higher weight value servers than the lower weight value servers. The policy ensures the distribution that you want, based on the weights that are assigned to the cluster members.
