1Z0-134 Free Practice Test

Your organization is using a Multi data source (MDS) on WebLogic Server to support applications connecting to an Oracle RAC database. You have been tasked with configuring a new callback handler for the MDS.
Which two statements are true concerning related MDS options and behavior? (Choose two.)

1. A. Callback handlers are optional when using the Failover MDS Algorithm.
2. B. If the Failover Callback Handler attribute is set on the MDS, the Test Frequency attribute is no longer used.
3. C. Callback handlers are called for both failover and failback decisions.
4. D. You can register only one callback handler for each WebLogic serve

Correct Answer: CD
C: A callback handler used to control the failover and failback within a multi data source must include an implementation of the weblogic.jdbc.extensions.ConnectionPoolFailoverCallback interface.
D: You can register a callback handler with WebLogic Server that controls when a multi data source with the Failover algorithm fails over connection requests from one JDBC data source in the multi data source to the next data source in the list.

What is the file extension for a domain extension template? (Choose the best answer.)

1. A. .jar
2. B. .zip
3. C. .ext
4. D. .tpl
5. E. .war
6. F. .ear

Correct Answer: A
The WebLogic Server Default Domain Extension Template filename is wls_default.jar. It extends the Basic WebLogic Server domain with a web application designed to guide new users through an introduction to WebLogic Server. References:

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.)

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

Correct Answer: AD
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.

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?

1. 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.
2. 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.
3. C. Create authorization policies for individual users whose employee attribute is true creating a constraint-only model,bypassing the use of a role entirely.
4. 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.

Correct Answer: B
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.

Examine the domain diagram:

Assume all servers are running and you have an online WLST session connected to the administration server.
Select two code options that would set the variable x as a reference to the machine02 configuration MBean. (Choose two.)

1. A. cd(‘/Machines/machine02’)x = cmo
2. B. x = getMBean(“/Machines/machine02”)
3. C. x = cmo.getRef(‘/Machines/machine02’)
4. D. getRef(“/Machines/machine02”)x = cmo.currentObj()
5. E. cmo.getMBean(‘/Machines/machine02’)x = cmo.currObj()
6. F. cd(‘/Machines/machine02’)x = getRef(cmo)
7. G. x = getConfiguration(‘/Machines/machine02’)

Correct Answer: AB
A: WLST online provides a variable, cmo, that represents the current management object. Example: wls:/mydomain/serverConfig/Servers/myserver/Log/myserver> cmo[MBeanServerInvocationHandler]mydomain:Name=myserver,Server=myserver,Type=
Log
B: wls:/mydomain/edit !> bean=getMBean('Servers/myserver/WebServer/myserver') wls:/mydomain/edit !> print bean [MBeanServerInvocationHandler]mydomain:Name=myserver,Type=WebServer,Server=my server
