Question # 4

You are troubleshooting why transactions are not being committed. After investigation, you realize that these transactions have enough time during the first phase of the two-phase commit, but not enough time during the second phase. Therefore, rather than committing, they are timing out and are being rolled back.

Which Java Transaction API (JTA) attribute needs a larger value?

Timeout Seconds

Abandon Timeout Seconds

Before Completion Iteration Limit

Checkpoint Interval Seconds

Unregister Resource Grace Period

Question # 5

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?

Proxy plug-in or hardware load balancer

Configured or dynamic cluster

Replicated or persistent HTTP sessions

Unicast or multicast communication

Single or multiple domains

Question # 6

Identify two reasons for defining machines and assigning servers to them in WebLogic Server. (Choose two.)

A machine can be the proxy to a cluster.

A machine definition is required to configure the Node Manager.

To reference an instance of WebLogic Server, you must know its machine and port.

A machine is a required organizational unit. A domain contains machines and machines contain servers.

WebLogic Server uses server machine assignments to help it choose servers in a cluster on which to replicate session state.

A machine’s Cluster Weight attribute may be used by load balancers to help them determine how often to send requests to servers assigned to that machine.

Question # 7

You need to monitor the HTTP session count for a running web application.

Identify three ways to perform this monitoring. (Choose three.)

Run the jstat tool in your JDK.

Write and run a custom WLST script.

Use the application’s Monitoring tab in the Administration Console.

Use the Monitoring Dashboard in the Administration Console.

Use the Cloud Control page in the Administration Console.

Question # 8

The startup of a WebLogic Server instance fails with the error message:

java.net.BindException : Address already in use

Which two methods help identify what is currently listening at the port and the IP this server is configured to be bound to? (Choose two.)

The pmap command lists all processes running with their associated port number.

The UNIX lsof command can report information on the process that is listening at a particular IP and port on the local machine.

netstat, which is available on Windows and Linux/UNIX, can report on the process bound to this IP and port.

pstat will report detailed runtime statistics on any process currently listening at this IP and port.

The Linux port watching tool PortInfo can raise an alert anytime a process attempts, succeeds, or fails to connect to a specific IP and port. It can also be used to identify if a port is being used by a java process.

Question # 9

Which two statements are true about WebLogic data sources? (Choose two.)

Data sources are targeted to a domain.

Data sources are bound in the JNDI tree of a server.

Data sources are based on the JMS specification.

A data source contains a connection pool.

A domain requires at least one data source.

Question # 10

You are creating and configuring a cluster by using the administration console. Which two statements are true? (Choose two.)

All servers that will be part of the cluster must be created before the cluster is created.

You must pick the cluster messaging mode.

Even though you create a non-dynamic cluster, you can change it to a dynamic cluster later.

Once the cluster is created, you cannot change its messaging mode.

The administration console does not provide a way to manually migrate singleton services. It must be set up to be done automatically or by using WLST.
