MuleSoft Certified Integration Architect – Level 1 — Question 13

Additional nodes are being added to an existing customer-hosted Mule runtime cluster to improve performance. Mule applications deployed to this cluster are invoked by API clients through a load balancer.
What is also required to carry out this change?

Answer options

• A. API implementations using an object store must be adjusted to recognize the new nodes and persist to them
• B. A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion
• C. External monitoring tools or log aggregators must be configured to recognize the new nodes
• D. New firewall rules must be configured to accommodate communication between API clients and the new nodes

Correct answer: C

Explanation

The correct answer is C because external monitoring tools or log aggregators must be aware of the new nodes to ensure that they can monitor and aggregate logs effectively. Options A and B are incorrect because adjustments to object store implementations and provisioning a new load balancer are not mandatory to integrate additional nodes. Option D is also incorrect as existing firewall rules may already accommodate the new nodes without additional configurations.
