During a major online sale, an e-commerce website experiences slow page loads and timeouts. The network team observes that the web server's ingress link is saturated and the router's output queue is dropping packets. What is the best immediate action to improve the user experience for the highest-value customers?

Apply QoS policies that prioritize HTTP/HTTPS traffic and rate-limit bulk downloads.

Move the web server to a different subnet.

Disable the router's output queue to prevent drops.

Increase the server's TCP buffer size to handle more connections.

A network administrator needs to ensure that VoIP traffic receives priority over file transfers on a congested link. Which technology is designed to manage network resources to meet the requirements of different applications?

Dynamic Host Configuration Protocol (DHCP)

Network Address Translation (NAT)

A company is deploying a real-time audio streaming service. The application requires a maximum jitter of 20 ms. The network team measures jitter of 25 ms on the primary path. They have the option to use a secondary path with jitter of 15 ms but higher average latency (100 ms vs. 80 ms). The application can tolerate up to 150 ms of latency. Which path should be used?

Use both paths and load-balance the traffic.

Use the primary path because it has lower latency.

Use the primary path and implement a jitter buffer to smooth the variation.

Use the secondary path because jitter is within the requirement, and latency is still acceptable.

A company runs a real-time trading application between two offices connected by a WAN link. The application requires sub-50 ms one-way latency and jitter below 10 ms. During peak hours, the link experiences congestion and latency spikes. The network team must ensure the trading traffic meets its requirements without over-provisioning the link. What should they implement?

Move the application to a cloud provider to reduce latency.

Increase the WAN link bandwidth to eliminate all congestion.

Enable TCP window scaling on the routers to speed up the application.

Apply QoS marking and a low-latency queue for the trading traffic.

A user reports that a web application feels sluggish, but large file downloads are fast. The application uses many small API calls that each require a round trip to the server. Which network constraint is most likely causing the perceived sluggishness?
