2. Memory-to-memory replication in Both client and server mode
3. Session affinity in Web server plug-in
4. Database persistence

Answer: C

QUESTION 48
When adding a new member to a cluster, why might it be necessary for an administrator to select the option for generating unique HTTP ports?

1. To avoid port conflicts with other servers on the same node
2. To ensure that cluster members on different nodes have unique ports
3. To prevent other applications from using these ports
4. To enable encryption over the secure HTTP ports

Answer: A

QUESTION 49
Mapping J2EE security roles to users is a function of:

1. Installing an application
2. Defining the JDBC connections to the backend databases.
