A branch office has finished work on a new project and needs to send the data back to the main office where the project will be stored and accessible for the rest of the company. The company…

Load balancing distributes traffic across multiple servers or links to improve availability and throughput, but does not control how different traffic types share available bandwidth.

Multipathing provides redundant network paths for fault tolerance and increased throughput, but does not prioritize or separate traffic types to prevent interference.

Bandwidth compression reduces the size of data to improve effective throughput, but does not prioritize or segregate traffic types to prevent one service from impacting another.

QoS (Quality of Service) enables network administrators to classify and prioritize traffic types, assigning bandwidth limits or priorities to specific flows. By configuring QoS policies, the administrator can throttle or deprioritize the large file transfer traffic while guaranteeing sufficient bandwidth for email and web services, ensuring all traffic coexists without interference.
