Question # 1

One Managed Server that is part of a large domain throws java.lang.OutOfMemory errors (OOM) occasionally.

You have been monitoring this server with the jvisualVM tool but that didn’t help because the issue occurs infrequently and not a specific scenario. So you decided to force the server to dump the heap memory as soon as an OOM gets thrown in order to analyze the dump file later.

How do you modify the Java HotSpot startup command to enable this feature and save the dump in the directory D:\hprof-dumps\?

A.

Add -XX:+DumpHeapOnOutOfMemory -XX:DumpPath= D:\hprof-dumps.

B.

Add -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=D:\hprof-dumps.

C.

Add -XX:+DumpHeapOnOutOfMemoryError -XX:HeapPath=D:\hprof-dump.

D.

Add -XX:+HeapDumpOnOutOfMemory -XX:HeapDumpPath=D:\hprof-dumps.

E.

Add -XX:+HeapDumpOnOutOfMemoryError -XX:DumpPath=D:\hprof-dumps.

F.

Add -XX:+HeapDumpOnOutOfMemoryException -XX:HeapDumpPath=D:\hprof-dumps.

Question # 2

A WebLogic Server (WLS) domain was recently updated from WLS 10.3.6 to WLS 12.1.12.

What is the mode of operation of the Node Manager after the update and what is needed to keep the same behavior as in WLS 10.3.6?

A.

Nothing, Node Manager runs and behaves the same on both WLS versions

B.

Node Manager runs in “per machine” mode and nothing is needed to keep the same behavior.

C.

Node Manager runs in “per domain” mode and requires manual steps to return to “per machine” mode, used in WLS 10.3.6.

D.

Node Manager mode of operating and behavior can be selected in Reconfiguration Wizard.

Question # 3

A domain defines four machines: host01, host02, host11, and host12. It also defines a dynamic cluster whose Machine Name Match Expression is set to the value “host1*”.

Which of the machines will be used to host servers in this dynamic cluster?

A.

host01 and host11 only

B.

host11 and host12 only

C.

host11 only

D.

all machines

E.

the default machine of the domain

F.

host01 only

Question # 4

You monitor a running JDBC data source with the console and note the following values:

    Current Capacity = 10

    Current Capacity High Count = 20

Identify two plausible explanations for these metrics. (Choose two.)

A.

The workload was lower than it is now

B.

The statement cache size is 20

C.

The pool size has increased

D.

The statement cache size is 10

E.

The pool size has decreased

F.

The workload was higher than it is now

Question # 5

You want to start the managed server called managed1 in “Standby” mode, to keep it as a “hot backup”. Which statement about your domain configuration must be true?

A.

The server managed1 must be of a cluster.

B.

Your domain has an administration port.

C.

Only the admin server can start in “Standby” mode.

D.

There is no such thing as “Standby” mode.

Question # 6

In memory replication in your cluster seems to be slow. You decide to create a replication channel for your cluster. Which two statements are true? (Choose two.)

A.

The channel is used for heartbeats so they do not interfere with replication communication

B.

Each server in the cluster must have this named replication channel configured on it

C.

If no replication channel is configured, then sessions are persisted to the file system or the database

D.

The channel can be used for stateful session bean replication

E.

The channel cannot use a secure protocol

Question # 7

While using the Configuration Wizard to create a new domain, you do not set the Listen Address for the administration server and accept the default value. What is the result?

A.

Server startup fails

B.

The server binds to localhost

C.

The server prompts for an address when it is started the first time

D.

The server attempts to bind to all network interfaces on the host OS

Question # 8

You need to configure WebLogic Server to satisfy the needs of your new application that will update more than one data set on several databases in the same transaction.

All updates will be committed or rolled back at the end of the transaction.

Which setting should be considered?

A.

Enable Use XA Data Source Interface in the transaction properties of each data source.

B.

WebLogic Server supports distributed transactions by default, so no specific settings are required.

C.

Split the transaction into multiple local transactions.

D.

Configure your data sources with the available XA-compliant driver for your DBMS.

E.

Enable Two-Phase Commit in each data source.

Question # 9

You are in the process of planning a deployment in which a single WebLogic cluster will host a web application. There are several options to consider.

Which is not a valid decision?

A.

Proxy plug-in or hardware load balancer

B.

Configured or dynamic cluster

C.

Replicated or persistent HTTP sessions

D.

Unicast or multicast communication

E.

Single or multiple domains

Question # 10

A web application is configured for in-memory replication and is deployed to a cluster. This cluster is distributed across two buildings on a university campus. For performance reasons, you require that session replication occur within the building whenever possible.

How do you implement this requirement?

A.

Disable the dynamic server list in the proxy plug-in.

B.

Configure the cluster to use multicast communication.

C.

Configure the application’s cookies parameters.

D.

Configure each server’s replication group.
