Oracle WebLogic Server 12c: Administration I — Question 64

As the technical lead for your project, you have been asked to recommend a new solution to handle frequently increasing loads on your applications. The
WebLogic 12.1.2 domain currently runs with two clusters of three servers with request being filtered and passed by a proxy server that users the round ""robin algorithm.
However, the load sometimes exceeds the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?

Answer options

• A. Add a third cluster and spread existing server instances across the clusters.
• B. Modify the proxy server load balancing algorithm to weight based.
• C. Configure dynamic clusters and specify the number of server instances you anticipate needing at peak load.
• D. Tune work managers to optimize work.
• E. Replace the software load balancer with a hardware load balancer.

Correct answer: C

Explanation

The correct answer, C, suggests configuring dynamic clusters, which allows for scalability by automatically adjusting the number of server instances based on demand. Option A, while it adds a cluster, does not address the scalability issue directly. Option B changes the load balancing method but does not increase capacity. Option D focuses on tuning work managers, which may optimize performance but does not solve the underlying capacity problem. Option E involves a hardware change that may not necessarily improve scalability.
