350-901 · Question #98

Given an application that implements a basic search function as Well as a video upload function , which two load-balancing approaches optimize the application's user experience? (Choose two.)

The correct answer is B. Video upload requests should be routed to the endpoint with highest data throughput. D. Search requests should be routed to the endpoint with lowest round-trip latency. Different traffic types have different performance requirements - video uploads need maximum throughput while search queries need minimum latency to feel responsive.

Why each option

Different traffic types have different performance requirements - video uploads need maximum throughput while search queries need minimum latency to feel responsive.

AVideo upload requests should be routed to the endpoint using an intermediate hop.

Routing through an intermediate hop adds additional network hops and latency, which degrades performance for any traffic type and provides no benefit for video uploads.

BVideo upload requests should be routed to the endpoint with highest data throughput.Correct

Video uploads transfer large amounts of data sequentially, making throughput the dominant factor for performance. Routing to the endpoint with the highest data throughput minimizes total transfer time and prevents bottlenecks for large file uploads.

CVideo upload requests should be routed to the endpoint with lowest round-trip latency.

Lowest round-trip latency is the correct metric for interactive search requests, not for video uploads where sustained throughput - not ping time - determines how quickly large files complete.

DSearch requests should be routed to the endpoint with lowest round-trip latency.Correct

Search queries are small, interactive requests where the user is actively waiting for a result. Routing to the lowest round-trip latency endpoint directly reduces perceived response time and improves the interactive user experience.

ESearch requests should be routed to the endpoint with highest data throughput.

Highest data throughput matters for bulk transfers like video uploads, not for search queries, where the payload is tiny and latency determines responsiveness.
