Question 5
Consider a multiple node domain. On the administration servers 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. Test the connection to verify the database’s availability
A. You must also set the domain attribute “CLASSPATH Discovery Enabled.”
B. Add a new connection to the data source if none are available
B. Each machine that hosts WebLogic Servers has its own domain directories. The script must be modified there as well.
C. Close the connection to return the connection to the data source
C. Only the first server to receive the new configuration from the administration server gets the updated CLASSPATH
D. Request a connection from the data source
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
E. Look up the data source using the JNDI name

Question 9
You are using the Configuration Wizard to create a new domain that will host an EJB application without a cluster. Remote EJB clients can therefore take advantage of WebLogic Servers load balancing and failover capabilities. However, a proxy server exists between the EJB clients and this new cluster. Which cluster attribute should you modify in the Configuration Wizard to ensure that external EJB clients are routed correctly through the proxy?
