Oracle WebLogic Server 12c: Administration I — Question 21

Consider an application that comprises both web and EJB components.
What are two benefits of implementing a multitier cluster architecture over a single-tier(basic) cluster architecture? (Chose two.)

Answer options

• A. Dynamic clusters are only supported for the multitier architecture
• B. Remote EJB access is blocked
• C. Each cluster can be scaled independently
• D. Future web clusters can share the same EJB tier
• E. All servers can be managed (started/stopped) together

Correct answer: D, E

Explanation

The correct answers D and E highlight that future web clusters can leverage the same EJB tier, promoting resource efficiency, and that all servers can be managed together, simplifying administration. Options A and B are incorrect as dynamic clusters are not exclusive to multitier architecture, and remote EJB access is typically not blocked but rather facilitated in such setups. Option C, while true, does not directly highlight a specific advantage over single-tier architecture.
