Question 5

Single choice

You are asked to configure Node Manager for your production environment. You are considering whether to use the Java version or the script-based version of Node Manager.

Which statement correctly describes the difference between the two versions?

A
If you are installing WebLogic Server on a Windows system, you must use the Java version of Node Manager.
B
The script-based version of Node Manager can be used in conjunction with inetd on supported UNIX systems.
C
The script-based version of Node Manager requires a larger footprint than the Java version.
D
When Node Manager is used for consensus leasing, you may see faster performance with the script-based version.

Reveal answer details Close answer details

Correct answerA

Explanation

Java-based Node Manager runs within a Java Virtual Machine (JVM) process. It is recommended that you run it as a Windows service on Windows platforms and as an operating system service on UNIX platforms.
For UNIX and Linux systems, WebLogic Server provides a script-based version of Node Manager.

Question 6

Single choice

A hardware load-balancer (HWLB) is positioned as the primary entry point into your WebLogic Server domain. Aspects of your application use SSL to protect data on the network from your clients to your domain.

Which configuration provides the best performance for your domain? (Choose the best answer.)

A
Configure the HWLB to use an SSL hardware accelerator and terminate SSL.
B
Configure the HWLB to use pass-through SSL, configure an SSL hardware accelerator on WebLogic, and terminate SSL.
C
Configure the HWLB to delegate SSL handling to the WebLogic Proxy Plug-in and terminate SSL.
D
Configure the HWLB to use pass through SSL to the WebLogic Server that it connects to, and terminate SSL.

Reveal answer details Close answer details

Correct answerA

Explanation

In most of the architectures, the SSL is terminated at the hardware load balancer for performance reasons and allows the internal traffic to use HTTP for communication.

Question 7

Single choice

You intend to introduce ordering in message processing for your JMS destination by creating a destination key.

Which statement is true about the JMS Destination Key configuration? (Choose the best answer.)

A
A JMS Destination Key cannot be specified using WLST.
B
A JMS Destination Key cannot be used to sort messages in a Last In First Out order.
C
A JMS Destination Key allows a user-defined sort key.
D
A Destination Key can be applied to the message body.

Reveal answer details Close answer details

Correct answerA

Explanation

The WebLogic Server Administration Console enables you to configure, modify, target, and delete destination key resources in a system module.

Incorrect Answers:
B: As messages arrive on a specific destination, by default they are sorted in FIFO (first-in, first-out) order, which sorts ascending based on each message's unique JMSMessageID. However, you can use a destination key to configure a different sorting scheme for a destination, such as LIFO (last-in, first-out).

C: Attribute Sort Key: The message sort key or the name of a message header field on which to sort.
Message header field keys start with the letters JMS and ignore the key type setting.
Valid values only (user-defined sort key not possible):

JMSMessageID
JMSTimestamp
JMSCorrelationID
JMSPriority
JMSExpiration
JMSType
JMSRedelivered
JMSDeliveryTime

Question 9

Single choice

You are configuring the principals needed to fulfill the security requirements of an application within a sandbox environment that uses the WebLogic Server-embedded LDAP server.

The given security requirements provided have outlined the following facts about some test principals:

One security requirement states that internal patient data can be viewed only by physicians who are employees.

What is an appropriate way to fulfill this security requirement from a principal perspective using the provided information?

A
Create an authorization policy that grants access if a user is a member of the physicians group and their employee attribute is true, bypassing the use of a role entirely.
B
Create an ACL that grants access if a user is a member of the physicians group and their employee attribute is true, bypassing the use of a role entirely.
C
Create authorization policies for individual users whose employee attribute is true creating a constraint-only model, bypassing the use of a role entirely.
D
Create an authorization policy that denies access if a user is a member of the physicians group and their employee attribute is false, bypassing the use of a role entirely.

Reveal answer details Close answer details

Correct answerB

Explanation

Security policies replace access control lists (ACLs) and answer the question "Who has access to a WebLogic resource?".

You assign security policies to any of the defined WebLogic resources (for example, an EJB resource or a JNDI resource) or to attributes or operations of a particular instance of a WebLogic resource (an EJB method or a servlet within a Web application). If you assign a security policy to a type of WebLogic resource, all new instances of that resource inherit that security policy. Security policies assigned to individual resources or attributes override security policies assigned to a type of WebLogic resource.

Question 10

Multiple choice

You need to update a database accessed by an application that uses a WebLogic server data source. It has been decided that the data source on WLS should first be shut down.

You have been asked to advise as to whether they should execute a shutdown() or a forceShutdown() on the corresponding JDBCDataSourceRuntimeMBean.

Which two statements are true regarding the impact on the application that is using that data source? (Choose two.)

A
The shutdown() operation will fail if there are any reserved connections in use.
B
The forceShutdown() operation will allow 20 seconds for any reserved connections in use to complete prior to destroying the connection.
C
The shutdown() operation will send an HTTP 503 status code to clients.
D
The forceShutdown() operation will immediately cause any in-flight transaction to be rolled back.
E
The shutdown() operation will allow 20 seconds for any reserved connections in use to complete, otherwise the operation will fail.

Reveal answer details Close answer details

Correct answersA, D

Explanation

A: When you shut down a data source (not forcibly shut down), WebLogic Server closes database connections in the data source and shuts down the data source. If any connections from the data source are currently in use, the operation will fail.

D: When you forcibly shut down a data source, WebLogic Server closes database connections in the data source and shuts down the data source. All current connection users are forcibly disconnected.

Question 18

Multiple choice

Even though your company has a thorough procedure for testing applications in a pre-production environment prior to production deployment, you have decided to conduct additional testing of a particular application after it is deployed. You choose to deploy the application in administration mode.

Which three statements are true? (Choose three.)

A
The application deployment must use the edeploy option using a unique version string.
B
You must configure an administration port for the entire domain, or an administration channel for the targeted server.
C
The application must first be distributed to the targeted server prior to starting it in administration mode.
D
The application cannot have any dependencies on any shared Java EE libraries.
E
After testing, the application can be dynamically transitioned to start accepting all client requests.

Reveal answer details Close answer details

Correct answersB, C, E

Explanation

B: Distributing an application copies deployment files to target servers and places the application in a prepared state. You can then start the application in Administration mode, which restricts access to the application to a configured Administration channel so you can perform final testing without opening the application to external client connections or disrupting connected clients.

C: Distributing an application prepares it for deployment by copying its deployment files to all target servers and validating it. After you distribute an application, you can start it in Administration mode, which restricts access to the application to a configured Administration channel and allows you to distribute the application to a production environment (or distribute a new version of an application) without opening the application to external client connections.

E: While in Administration mode, you can connect to an application only via a configured Administration channel. This allows you to perform final ("sanity") checking of the application directly in the production environment without disrupting clients. After performing final testing, you can either undeploy the application to make further changes, or start the application to make it generally available to clients.

Incorrect Answers:
A: After performing final testing, you can either undeploy the application to make further changes, or start the application in Production mode to make it generally available to clients.

Question 19

Single choice

You are asked to create a WLST script to make live updates to a domain that has its administration server running. You want your script to mimic the actions of a WebLogic administrator by using the administration console and clicking the "Lock and Edit" button.

What commands would accomplish this?

A
edit() followed by startEdit()
B
lockDomain() followed by edit()
C
domainConfig() followed by cd(`Edit')
D
getLock(0) followed by edit()
E
clearPending() followed by lockDomain()
F
lockDomain() followed by editDomain()

Reveal answer details Close answer details

Correct answerA

Explanation

Not edit() navigates to the last MBean to which you navigated in the edit configuration MBean hierarchy or to the root of the hierarchy, DomainMBean.

StartEdit() starts a configuration edit session on behalf of the currently connected user. You must navigate to the edit configuration MBean hierarchy using the edit command before issuing this command.

Note: Click the Lock & Edit button to lock the configuration edit hierarchy for the domain. This enables you to make changes using the Administration Console.

Incorrect Answers:
B, F: No WLST command lockDomain().
D: No WLST command getLock().
E: No WLST command ClearPending.
