• Question 53:

  Indentify three tools that you can use to create a deployment plan.

  A. administration console
  B. weblogic.PlanGenerator
  C. the /autodeploy folder that is locked in the domain directory
  D. developer tools such as JDeveloper or Eclipse
  E. the /plan subfolder that resides outside the application archive
  A. administration console
  B. weblogic.PlanGenerator
  D. developer tools such as JDeveloper or Eclipse

  ---

  A: To create a deployment plan for a deployed application that does not already have a deployment plan, make a configuration change to the deployed application. When you make a persisted configuration change to a deployed application that does not have an existing deployment plan, the Administration Console automatically creates a deployment plan for you and prompts you for the location in which to save it.

  B: The weblogic.PlanGenerator is a Java-based deployment configuration tool. It is primarily intended for developers who want to export portions of a WebLogic Server deployment configuration into an XML deployment plan. weblogic.PlanGenerator also enables you to generate a basic WebLogic Server configuration for applications that have only J2EE deployment descriptors.

  D: Deployment plans can be created or edited through the deployment plan editor functionality available through the Web-based Oracle Enterprise Manager 10g Application Server Control Console interface and the J2EE and Studio Editions of the Oracle JDeveloper 10g integrated development environment.

• Question 54:

  Which two statements are true about multicast communication within a cluster?

  A. Multicast can be used for cluster heartbeat messages.
  B. Multicast is used to replicate session state between servers.
  C. Multiple clusters can share the same multicast address and port.
  D. You may disable multicast on individual cluster members.
  E. Multicast traffic is often limited to a single subnet.
  A. Multicast can be used for cluster heartbeat messages.
  E. Multicast traffic is often limited to a single subnet.

  ---

  A: WebLogic Server instances in a cluster communicate with one another using two basic network technologies:

  *

  IP sockets, which are the conduits for peer-to-peer communication between clustered server instances.

  *

  IP unicast or multicast, which server instances use to broadcast availability of services and heartbeats that indicate continued availability.

  E: In many deployments, clustered server instances reside within a single subnet, ensuring multicast messages are reliably transmitted. However, you may want to distribute a WebLogic Server cluster across multiple subnets in a Wide Area Network (WAN) to increase redundancy, or to distribute clustered server instances over a larger geographical area.

• Question 55:

  You run the following WLST script and it completes successfully. Which statement best describes what the script created?

  

  A. A CMO named myserver with the listen address 192.168.1.102 and port 8008
  B. A Managed Server named myserver with the listen address 192.168.1.102 and port 7001
  C. A Managed Server named myserver with listen address 192.168.1.102 and port 8008
  D. An Administration Server named myserver with the listen address 092.168.1.102 and port
  C. A Managed Server named myserver with listen address 192.168.1.102 and port 8008

  ---

  A managed server (not a CMO, not an administration server) is created.

  Port is 8008.

  Note: Listing: Creating a Managed Server

  connect("username","password")

  edit()

  startEdit()

  svr = cmo.createServer("managedServer")

  svr.setListenPort(8001)

  svr.setListenAddress("my-address")

  save()

• Question 56:

  Which two statements are true about adding servers to a cluster?

  A. When you create a cluster, you must add at least one server to it.
  B. Only managed servers can be in a cluster.
  C. The administration server is automatically added to a new cluster.
  D. You must explicitly identify which servers belong to the cluster.
  A. When you create a cluster, you must add at least one server to it.
  B. Only managed servers can be in a cluster.

  ---

  A cluster must include at least one server.

  A clustered is administered through an administration server, but the cluster consists of managed servers only.

• Question 57:

  Which three tasks can be performed by the Node manager?

  A. Start a server.
  B. Define a node server.
  C. Host the Node Manager console.
  D. Automatically restart a failed server.
  E. Kill a failed application on a server.
  F. Kill the process of a server that did not shut down properly.
  A. Start a server.
  B. Define a node server.
  D. Automatically restart a failed server.

  ---

  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)

• Question 58:

  Identify three properties required by the domain Configuration Wizard when creating a new domain.

  A. machine name
  B. Managed Server name
  C. domain startup mode
  D. domain name
  E. administrator username and password
  C. domain startup mode
  D. domain name
  E. administrator username and password

  ---

  C: Choose the Startup Mode Specify the startup mode for your domain. Either Development or Production

  D: The Create WebLogic Domain window prompts you to specify the name and pathname for the domain, and initiate its creation.

  E: The Configure Administrator Username and Password window prompts you to specify a username and password to be used for starting the Administration Server.

• Question 59:

  Refer to the Exhibit

  

  What is the meaning of the yellow triangle icon next to Listen Address?

  A. This attribute has no value.
  B. The server must be running to change this attribute.
  C. The server must be shut down to change this attribute.
  D. The server must be restarted for a change to this attribute to take effect.
  E. This attribute is read only and cannot be changed in the administration console
  D. The server must be restarted for a change to this attribute to take effect.

  ---

  The server instance for which you configure the listen address does not need to be running. If it is running, you must restart it after you complete these steps. Reference: Administration Console Online Help, Configuring the Listen Address from the Administration Console

• Question 60:

  Which four tasks can be accomplished in the administration console only after the configuration is locked?

  A. deploying an application
  B. changing console preferences
  C. creating a new JMS Server
  D. monitoring the health of a server
  E. enabling the Administrator Port
  F. creating a new Managed Server
  G. adding a new user to the default authentication provider
  A. deploying an application
  C. creating a new JMS Server
  E. enabling the Administrator Port
  F. creating a new Managed Server

  ---

  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.
