D. Using the administration console, select the appropriate machine and click stop.
E. The administration server goes into ADMIN mode if it can no longer Communicate with Node Manager.
F. The managed servers that Nod Manager started go into ADMIN mode if they can no longer communicate with Node Manager.
You are using the Administration console to monitor a resource.
Which three techniques can you use to customize the monitoring output?
A. Sort the rows by a specific column.
B. Limit the number of rows displayed.
C. Change the order of the displayed columns.
D. Views the rows from a specific time range.
E. Combine (add) multiple columns together.

F. Kill a server process that did not shut down property.
Which three statements about patching Web Logic server (WLS) by using Opatch are true?
A. Each patch comes with a "read me" file containing installation instructions.
B. You can use Opatch to see which patches are currently applied to WebLogic server.
C. Opatch is a GUI tool and requires the operating system to have a window manager.
D. Opatch requires a JDK to run.
E. After installing WLS, you download the Opath utility from Oracle support.
F. Each patch ZIP file comes with the Opatch utility.
Consider a domain with an existing JDBC data source, which connects to an Oracle database. Your database administrator requests that the JDBC connections to this database now specify a different username.
Which data source attribute would you modify to implement this requirement?
A. Properties
B. Credentials
C. Username
D. Login
E. URL
Which three runtime metrics can you monitor or collect from WebLogic Server applications?
A. Average execution time for a web application URL.
B. Number or transaction rollbacks for a web server
C. Maximum HTTP session timeout for a web application
D. Number of current sessions for an EJB
E. Numbers of faults /errors for a web service
F. Number of instances of an EJB
Identify two advantages of using a Single Client Access Name (SCAN) when configuring a GridLink data source. (Choose two.)
A. The Fast Connection Failover (FCF) pattern, which allows rapid failure detection, is enabled
B. The more sophisticated runtime connection load balancing (RLCB) is used; without SCAN, load balancing reverts to a simple round-robin scheme
C. SCAN is required for the GridLink data source to use an XA driver
D. The database URL is shorter because it contains one SCAN alias and port as opposed to a host and port foe each RAC node
E. The data source configuration does not need to be updated when new nodes are added to the RAC cluster
Consider a data source whose Inactive Connection Timeout has been set to 60 seconds. You suspect that an application is not returning JDBC connections to this data source. In response, you go to the data source's Monitoring tab in the Administration Console.
Which of the available columns will confirm your suspicious?
A. State
B. Active Connections Current Count
C. Connection Delay Time
D. Leaked Connection Count
E. Current Capacity
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. Test the connection to verify the database's availability
B. Add a new connection to the data source if none are available
C. Close the connection to return the connection to the data source
D. Request a connection from the data source
E. Look up the data source using the JNDI name
Consider a multiple node domain. On the administration server's node, you edit setDomainEnv.sh in the bin directory and add a new JAR file to the CLASSPATH. You stop and restart all three WebLogic Server in the domain. Upon investigation, you discover that only applications deployed to one WebLogic Server are able to access the JAR file code. How do you explain this?
A. You must also set the domain attribute "CLASSPATH Discovery Enabled."
B. Each machine that hosts WebLogic Servers has its own domain directories. The script must be modified there as well.
C. Only the first server to receive the new configuration from the administration server gets the updated CLASSPATH
D. The CLASSPATH is not for application code. It is for interval WebLogic Server code. So, only applications deployed to the administrative server can access code through the CLASSPATH
