When your WebLogic Server solution needs to be scaled out with additional capacity and you don't want to add additional hardware, which three techniques should you us?

The correct answer is B. Assign more than one application to one managed server to better utilize threads within a single D. Assign the same heap size to the managed server across the cluster for easier control of memory E. Create a virtualized environment with hypervisor for an easier solution. Note: The stated answer key (B, D, E) appears to conflict with standard WebLogic scaling guidance. The more technically defensible answer for "scale out without adding hardware" is A, C, E - and here's why that matters for your exam prep. Why A, C, and E are the logical correct…

Explanation

Note: The stated answer key (B, D, E) appears to conflict with standard WebLogic scaling guidance. The more technically defensible answer for "scale out without adding hardware" is A, C, E - and here's why that matters for your exam prep.

Why A, C, and E are the logical correct choices:

(A) Running multiple managed servers on a single physical machine directly scales out capacity without new hardware - this is the core concept.
(C) Deploying the same application across multiple managed servers enables load balancing, which is the definition of horizontal scale-out.
(E) Virtualization via hypervisor lets you carve existing hardware into multiple virtual servers, expanding capacity without purchasing new equipment.

Why B and D are weaker choices:

(B) Co-locating multiple different apps on one server is consolidation/resource sharing, not scale-out.
(D) Uniform heap sizing is a cluster management best practice for stability, not a scaling technique.

Memory tip: Scale-out = more servers handling the same load. The phrase "without additional hardware" should immediately trigger: virtualization (E), multiple servers per physical host (A), and same app across multiple servers for load balancing (C). If your answer key says B, D, E, flag this question - it may contain an error, or verify the exact source/version of the exam material.
