• Question 71:

  Which three statements are true about the administration console?

  A. The administration console cannot be disabled.

  B. The context path of the administration console may be changed.

  C. The administration console may be extended.

  D. If a domain is in Development Mode, the administration console no longer requires an administration-level user when logging in.

  E. If a domain is in Production Mode, access to the administration console must be made through secure port.

  F. If the domain's Administration Port is enabled, access to the administration console must be made only through that port.

  Correct Answer: BCF

  B: The Console Context Path is an advance configuration option. The context path that you want to use in URLs that specify the Administration Console. Note: Create a new WebLogic Server domain based on a template. Templates allow you to re-create an existing do- main for use in another context, such as migrating a domain containing an application under development to a pro- duction environment.

  C: An Administration Console extension is a WAR file that contains the resources for a section of a WebLogic Portal Web application. When you deploy the extension, the Administration Console creates an in-memory union of the files and directories in its WAR file with the files and directories in the extension WAR file. Once the extension has been deployed, it is a full member of the Administration Console: it is secured by the WebLogic Server security realm, it can navigate to other sections of the Administration Console, and if the extension modifies WebLogic Server resources, it participates in the change control process.

  Incorrect answers:

  A: Exposing the console in your production environment might be security issue. In those cases you can either dis- able the console or hide it. Needless to say if you disable the console then your only option is to depend on com- mand-line and scripting tools for any other administration activity or to even enable the console back. But hiding will provide a level or security.

  To disable the console:

  In the admin console navigate to --> General --> Advanced Options --> Console Enabled. De-select that option to disable console (restart required).

  To hide the cosole:

  E: Access through a secure port is recommended, but not required:

  The administration port requires all communication to be secured using SSL. By default, all servers in a do- main use demonstration certificate files for SSL, but

  these certificates are not appropriate for a production environment.

• Question 72:

  You are creating a new domain by using the Configuration Wizard, based solely on the Basic WebLogic Server Domain product (no template). Select three resources that you can create while still in the Configuration Wizard.

  A. Administration Server

  B. Managed Server

  C. Data Server

  D. JMS Server

  E. Cluster

  F. Domain Log

  Correct Answer: ABE

  A: The Configure the Administration Server window prompts you to define the configuration information for the Administration Server, including: Administration Server name Listen address Nonsecure and secure (optional) listen ports

  B: The Configure Managed Servers window prompts you to define the configuration information for one or more Managed Servers, including: Managed Server name Listen address Nonsecure and secure (optional) listen ports

  E: The Configure Clusters window prompts you to define the configuration information for one or more clusters, including: Cluster name Multicast address and port Cluster address that identifies the Managed Servers in the cluster Frontend host if you are using a proxy server or a firewall. Frontend HTTP port if you are using a proxy server or a firewall.

• Question 74:

  Your company is developing batch order system that utilities JMS. Each order message that is created will be broadcasted to and consumed by several order processing and billing applications.

  As part of configuring the domain that will support this system, which type of JMS destination resource should you create?

  A. Grid

  B. Queue

  C. Topic

  D. Batch

  E. Client

  Correct Answer: C

  A JMS destination identifies a queue (point-to-point) or topic (publish/subscribe) resource within a JMS module.

  A JMS topic identifies a publish/subscribe destination type for a JMS server. Topics are used for asynchronous peer communications. A message delivered to a

  topic is distributed to all consumers that are subscribed to that topic.

• Question 75:

  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.

  A. The pool size has increased.

  B. The pool size has decreased.

  C. The workload was higher than it is now.

  D. The workload was lower than it is now.

  E. The statement cache size is 10.

  F. The statement cache size is 20.

  Correct Answer: BC

  The pool size has decreased from a maximum 20 to 10.

  The workload has been 20. Now it is 10. The workload was higher.

  Note: Current Capacity: The current count of JDBC connections in the connection pool in the data source.

  Current Capacity High Count: Highest number of database connections available or in use (current capacity) in this instance of the data source since the data

  source was deployed.

  Note:

  Incorrect answers:

  E, F: The statement cache deals with statements. Current capacity and Current Capacity High Count deals with connections.

  Statement Cache Size shows the total number of statements to cache for each connection in each instance of the data source. WebLogic Server can reuse

  statements in the cache without reloading the statements, which can increase server performance. Each connection in the connection pool has its own cache of

  statements.

• Question 76:

  Refer to the Exhibit.

  

  Which three statements are true about using the administration console to shut down a server?

  A. The configuration must first be locked.

  B. The choice "Force Shutdown Now" drops in-work requests.

  C. Both the choices, "When work completes" and "Force Shutdown Now", reject any new requests.

  D. The choice "When work completes" allows in work requests to complete before the server down.

  E. The administration console can be used to shut down Managed Servers, such as managed not the Administration Server.

  Correct Answer: BCD

  B: select Force Shutdown Now to stop the server immediately without completing ongoing tasks.

  D: Select When Work Completes to gracefully shut down the server A graceful shutdown gives WebLogic Server subsystems time to complete certain application

  processing currently in progress.

  Screenshot:

  

  Incorrect answers:

  A: You can shutdown a managed server without selecting "lock and edit".

  E: The Administration server can also be shutdown.

• Question 77:

  A managed server, myserver1, has a boot.properties file in the security directory. It was started with the startManageWeblogic.sh script(.cmd in windows) and his boot.properties file was used for its startup credentials.

  You just used the administration console to change all administrator passwords. To continue using boot.properties, what can you do?

  A. This is not possible. A boot.properties file can be used only with the Administration Server.

  B. Delete boot.properties. In the administration console, under the myserver configuration, select Generate Boot Identity file.

  C. You need not do anything- The password in boot .properties was automatically updated by administration console when you changed the password.

  D. Edit boot.propetties. Type over the encrypted password with the new password in clear text. The next time myserver1 is started, it will encrypt the password in the file.

  E. Delete boot .properties. Use the WLST encrypt () command to create a new boot.properties file containing the new password. Copy that file into the security directory of myserver1

  Correct Answer: D

  If you install the WebLogic Server Examples component, the default user weblogic is created that has permission to start and stop WebLogic Server. The default password is welcome1. If you change the password of the weblogic user, WebLogic Server does not automatically update this password in the boot.properties file, which is located in the DOMAIN_NAME/servers/AdminServer/security directory.

  If you change the password for user weblogic, you can use either of the following workarounds so that you can continue to boot a WebLogic Server instance via that username and its new password:

  *

  Remove the boot.properties file. Subsequently each time you start WebLogic Server, you are prompted for the username and password. The changed password for the weblogic user will be accepted.

  *

  Modify the existing boot.properties file, changing the username and password as follows:

  username=weblogic password=welcome1 Subsequently during the server startup process, the boot.properties file is encrypted again.

• Question 79:

  As an Oracle WebLogic Server administrator, you are given an EAR file application to deploy. Identity three reasons for creating an EAR file first.

  A. After the .ear file has been deployed, the developer will not have to ask for your assistance to deploy it again.

  B. The EAR file is created to avoid namespace clashes in the Java code.

  C. The EAR file can contain multiple WAR, EAR, and other resources to easily bundle together.

  D. The EAR file is required if you are deploying an application.

  E. The EAR file can declare application-wide security roles definitions.

  Correct Answer: ABE

  E: An EARfile contains:

  * Web module

  A WAR file containing the view logics like JSPs, Servlets, Html contents. Every web module must have one Web Deployment descriptor placed inside "WEB-INF/

  web.xml"

  web.xml is a J2EE standard deployment descriptor. Among other settings, it has a set of elements for configuring security for the web application.

  Note:

  *

  An EAR file provides a convenient way to bundle up all pieces of a J2EE application. It may contain Java Module, WAR Module or an EJB Jar module. An EAR can contain at least any one of these modules. EAR may contain more Modules as well.

  *

  To bring your portal online in a production environment, it is first necessary to prepare your portal application. Typical preparation steps include modifying deployment descriptors for the product, building the Enterprise archive (EAR) with all its pre-compiled classes, and deciding if you want to compress that EAR into an archive or leave it exploded.

• Question 80:

  You have selected Configuration Archive Enabled for the domain. When a configuration change and activated, where is the previous version of the configuration archived?

  A. in the Oracle database

  B. in the config directory

  C. in the pending directory

  D. in the console-ext directory

  E. in the configArchive directory

  Correct Answer: E

  You can configure WebLogic Server to make backup copies of the configuration files. This facilitates recovery in cases where configuration changes need to be reversed or the unlikely case that configuration files become corrupted. When the Administration Server starts up, it saves a JAR file named config-booted.jar that contains the configuration files. When you make changes to the configuration files, the old files are saved in the configArchive directory under the domain directory, in a JAR file with a sequentially-numbered name like config-1.jar.
