Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 29

Where should distributed load balancing occur in a horizontally scalable architecture?

Answer options

• A. firewall-side/policy load balancing
• B. network-side/central load balancing
• C. service-side/remote load balancing
• D. client-side/local load balancing

Correct answer: D

Explanation

The correct answer is D, as client-side/local load balancing allows for efficient distribution of requests among servers directly at the client level, which is crucial for scalability. Options A and B refer to load balancing approaches that are less efficient for distributed architectures, while option C, service-side/remote load balancing, introduces latency and can create bottlenecks.
