Correct Answer: ABD

Node Manager enables you to perform these tasks:

*

Start and stop remote Managed Servers. (A)

*

Monitor the self-reported health of Managed Servers and automatically kill server instances whose health state is "failed".

*

Automatically restart Managed Servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot. (D)

Correct Answer: BE

B: The Administration Server uses the machine definition in conjunction with the Node Manager application to start remote WebLogic Server instances.

E: By default, WebLogic Server attempts to create session state replicas on a different machine than the one that hosts the primary session state. You can further control where secondary states are placed using replication groups. A replication group is a preferred list of clustered servers to be used for storing session state replicas. Using the WebLogic Server Console, you can define unique machine names that will host individual server instances. These machine names can be associated with new WebLogic Server instances to identify where the servers reside in your system. Machine names are generally used to indicate servers that run on the same machine.

Correct Answer: B

B: keytool import Reads the certificate or certificate chain (where the latter is supplied in a PKCS#7 formatted reply) from the file cert_file, and stores it in the keystore entry identified by alias. If no file is given, the certificate or PKCS#7 reply is read from stdin. keytool can import X.509 v1, v2, and v3 certificates, and PKCS#7 formatted certificate chains consisting of certificates of that type.

Incorrect answers:

A: keytool --genkey generates a key pair (a public key and associated private key). Wraps the public key into an X.509 v1 self-signed certificate, which is stored as a single-element certificate chain. This certificate chain and the private key are stored in a new keystore entry identified by alias.

Description: Loads a trusted CA certificate into a keystore. If the keystore does not exist, it is created.

Correct Answer: E

Correct Answer: ABE

A: The main steps for creating a custom file store are as follows:

1.Create a directory where the file store's data will be persisted. 2.Create a custom file store and specify the directory location that you created. 3.Associate the

custom file store with the subsystem(s) or migratable target that will be accessing it, such as:

*For JMS servers, select the custom file store on the General Configuration page. *For Store-and-Forward agents, select the custom file store on the General

Configuration page. *For a Path Service, select the custom file store on the General Configuration page.

B: The main steps for creating a JDBC store are as follows:

Create a JDBC data source or multi data source to interface with the JDBC store. Create a JDBC store and associate it with the JDBC data source or multi data

source. It is highly recommended that you configure the Prefix option to a unique value for each configured JDBC store table.

Associate the JDBC store with the subsystem(s) that will be using it, such as:

For JMS servers, select the JDBC store on the General Configuration page. For Store-and-Forward agents, select the JDBC store on the General Configuration

page. For a Path Service, select the custom file store on the General Configuration page.

E: Each server instance, including the administration server, has a default persistent store that requires no configuration.

Note:

When a persistent message is sent, it is stored in the WebLogic Persistent Store. The persistent store provides a built-in, high-performance storage solution for

WebLogic Server subsystems and services that require persistence. For example, it can store persistent JMS messages or temporarily store messages sent using

the Store-and-Forward feature. The persistent store supports persistence to a file-based store or to a JDBC-enabled database.

Note 2: A persistent message is guaranteed to be delivered once-and-only-once. The message cannot be lost due to a JMS provider failure and it must not be

delivered twice. It is not considered sent until it has been safely written to a file or database. WebLogic JMS writes persistent messages to a WebLogic persistent

store (disk-base file or JDBC-accessible database) that is optionally targeted by each JMS server during configuration.

Correct Answer: B

WebLogic Server provides three different options for staging files: stage mode, nostage mode, and external_stage mode.

By default, WebLogic Portal's default staging mode is "stage."

Correct Answer: D

The following attributes are displayed in the exhibit:

Session Invalidation Interval (in seconds)

Session Timeout (in seconds)

debug-enabled

Maximum in-memory Sessions

These attributes are stored in the weblogic.xml file as the following elements:

invalidation-interval-sec

timeout-secs

debug-enabled

max-in-memory-sessions

Incorrect answers:

A: config.xml does not contain session related information.

The config.xml file consists of a series of XML elements. The Domain element is the top-level element, and all elements in the Domain are children of the Domain

element. The Domain element includes child elements, such as the Server, Cluster, and Application elements. These child elements may have children

themselves.

For example, the Server element includes the child elements WebServer, SSL and Log. The Application element includes the child elements EJBComponent and WebAppComponent. Each element has one or more configurable attributes. An attribute has a corresponding attribute in the configuration API. For example, the Server element has a ListenPort attribute, and likewise, the weblogic.management.configuration.ServerMBean class has a ListenPort attribute.

Correct Answer: AD

A (not B): For any given WebLogic Server instance, you can override the default filter and create a log filter that causes a different set of messages to be written to

the domain log file.

Note:

To create and configure a log filter:

1.

If you have not already done so, in the Change Center of the Administration Console, click Lock and Edit (not B) (see Use the Change Center).

2.

In the left pane of the Console, select the name of the active domain in the Domain Structure panel.

3.

On the Configuration: Log Filters page, click New.

4.

On the Create a New Log Filter page, enter a value to identify the filter in the Name field.

5.

Click Finish.

The new log filter appears in the Log Filters table.

6.

To configure a filter expression, in the Log Filters table, click the log filter name.

7.

On the Configuration page, in the Filter Expression text box, enter criteria for qualifying messages.

A filter expression defines simple filtering rules to limit the volume of log messages written to a particular log destination.

See D) below.

8.

Click Save.

The filter and filter expression are listed in the Log Filters table.

D: Log Filter Configuration

Use this page to define a custom log filter to restrict the set of messages that one or more servers send to a message destination, such as the domain log,

standard out, server log file, or memory buffer of recent log events.

You can click Edit to type or paste in an expression directly, using WLDF Query Language syntax (see Related Topics, below); or you can click Add Expression to

construct an expression by choosing items from lists.

Once you create a filter, you cannot change its name. Instead, you must create a new filter under a different name.

Correct Answer: ACEF

A: Steps to Deploy Application using Administration Console

1.

Start the Admin Server and Managed Server.

2.

Navigate to Administration console http://localhost:7001/console and login.

3.

Navigate to Domain Environment > Deployments. Lock the console.

4.

Etc.

E: To enable the administration port for your domain:

1.

If you have not already done so, in the Change Center of the Administration Console, click Lock and Edit

2.

Shutdown all Managed Servers in the domain. You cannot enable the administration port dynamically on a Managed Server.

3.

Ensure that all servers in the domain are properly configured to use SSL.

4.

In the left pane of the Console, under Domain Structure, select the domain name.

5.

Select Configuration > General and select the Enable Administration Port check box to enable the SSL administration port for this domain.

6.

In the Administration Port field, enter the SSL port number that server instances in the domain use as the administration port. You can override an individual server instance's administration port assignment on the Advanced options portion of the Configuration: General page for the server instance.

7.

Click Save.

8.

To activate these changes, in the Change Center of the Administration Console, click Activate Changes.

Note: If you want to use the Administration Console to make configuration changes, you must first click the Lock and Edit button in the Change Center. When you click Lock and Edit, you obtain a lock on the editable hierarchy of Configuration MBeans for all servers in the domain (the edit tree). As you make configuration changes using the Administration Console, you click Save (or in some cases Finish) on the appropriate pages. This does not cause the changes to take effect immediately; instead, when you click Save, you are saving the change to the edit tree and to the DOMAIN_NAME/pending/config.xml file and related configuration files. The changes take effect when you click Activate Changes in the Change Center. At that point, the configuration changes are distributed to each of the servers in the domain. If the changes are acceptable to each of the servers, then they take effect. (Note, however, that some changes require a server to be restarted.) If any server cannot accept a change, then all of the changes are rolled back from all of the servers in the domain. The changes are left in a pending state; you can then either edit the pending changes to resolve the problem or revert the pending changes.

Incorrect answers:

G: There is no need to lock the configuration when you add a user (to the default authentication provider). Note: To create a new user in the embedded WebLogic LDAP server:

1.

Log in to the Oracle WebLogic Server Administration Console

2.

In Oracle WebLogic Server Administration Console, select Security Realms from the left pane and click the realm you are configuring. For example,myrealm.

3.

Select Users and Groups tab, then Users. Click New. etc.

Correct Answer: AB

A: Target

The target that this JMSServer is deployed to.

See step 5) in the Note below.

B: Persistent Store

The file or database in which this JMS server stores persistent messages. If unspecified, the JMS server uses the default persistent store that is configured on

each targeted WebLogic Server instance.

Note: See step 4) below.

To create a JMS server:

1.

If you have not already done so, in the Change Center of the Administration Console, click Lock and Edit

2.

In the Administration Console, expand Services > Messaging and select JMS Servers.

3.

On the Summary of JMS Servers page, click New.

Note: Once you create a JMS server, you cannot rename it. Instead, you must delete it and create another one that uses the new name.

4.

On the Create a JMS Server page:

a.

In Name, enter a name for the JMS server.

b.

In Persistent Store, select a pre-configured

custom file or JDBC store that will be used by

the JMS server or click the Create a New

Store button to create a store on the fly.

5.

On the Select Targets page, select the server instance or migratable server target on which to deploy the JMS server.

Migratable targets define a set of WebLogic Server instances in a cluster that can potentially host a pinned service, such as a JMS server.

Correct Answer: BD

In WebLogic Server, you configure database connectivity by adding data sources to your WebLogic domain. WebLogic JDBC data sources provide database access and database connection management. Each data source contains a pool of database connections that are created when the data source is created and at server startup. Applications reserve a database connection from the data source by looking up the data source on the JNDI tree or in the local application context and then calling getConnection(). When finished with the connection, the application should call connection.close() as early as possible, which returns the database connection to the pool for other applications to use.
