Oracle WebLogic Server 12c: Administration I - 1z1-133

Consider a domain that includes a Node Manager home directory. One way to enroll each Node Manager with your domain is with the WLST command nmEnroll().
Select the two scenarios where you do not need to use this command to perform the same task? (Choose two.)

• A. Use the administration console. Select the machine, then the Configuration and Node Manager tabs.
  Select "Enroll with the Domain." Save and activate your changes
• B. You create a managed server template by using the pack utility. Then create the domain by using the unpack utility on the new machine where Node Manager will run
• C. The Node Manager is on the machine where the domain was created by using the Configuration Wizard
• D. Use the script enrollNodeManager.sh found under the WEBLOGIC_HOME directory in server/bin

Which three statements about patching WebLogic Server (WLS) by using OPatch are true? (Choose three.)

• A. Each patch ZIP file comes with the OPatch utility.
• B. OPatch is a GUI tool and requires the operating system to have a window manager.
• C. Each patch comes with a "read me" file containing installation instructions.
• D. You can use OPatch to see which patches are currently applied to WebLogic Server.
• E. After installing WLS, you download the OPatch utility from Oracle Support.
• F. OPatch requires a JDK to run.

You set up two network channels for server-to-server communication. You want channel X to be used more than channel Y, so you give channel X a higher Channel Weight. You want to see if indeed channel X is used more.
You use the administration console and look at both channels under each one's Monitoring tab. What scenario would best assure you that channel X has an overall higher connection rate?

• A. Channel X Bytes Received is higher.
• B. Channel X Bytes Sent is higher.
• C. Channel X Accept Count is higher.
• D. Channel X Connections is higher.

You require high availability for HTTP sessions in a web application. In addition, you have the following constraints:
* There is little free memory on the machines hosting the cluster.
* HA must be guaranteed even when multiple machines fail simultaneously.
* You are not allowed to update the production databases schema.
Which is the best session persistence option?

• A. Whole-server migration
• B. Database persistence
• C. File persistence
• D. In-memory replication

Consider a WebLogic Java EE application that uses a JDBC data source.
Which three steps would the application developer typically write code to perform? (Choose three.)

• A. Close the connection to return the connection to the data source
• B. Test the connection to verify the database's availability
• C. Look up the data source using the JNDI name
• D. Request a connection from the data source
• E. Add a new connection to the data source if none are available
