A network administrator is monitoring a WAN link and observes that the average utilization is 70%, but the link occasionally experiences packet loss during peak hours. The administrator is considering whether to upgrade the link or implement QoS. Which approach is most appropriate?

Upgrade the link immediately to eliminate packet loss.

Implement QoS to prioritize critical traffic and reduce the impact of congestion, and monitor the results before upgrading.

Do nothing and accept the packet loss.

Implement QoS and upgrade the link at the same time.

What is the primary difference between bandwidth and throughput?

Bandwidth is measured in bytes per second, while throughput is measured in bits per second

Bandwidth is the theoretical maximum, while throughput is the actual measured rate

Throughput is the theoretical maximum, while bandwidth is the actual measured rate

They are the same and can be used interchangeably

Which factor is most likely to degrade WAN performance in a campus environment?

Low signal strength on fiber links

A company has a WAN link with high latency (150 ms) between two sites. Users access a central application that uses many small, sequential requests. The application is slow, and the link is not congested. Which WAN optimization technique would be most effective in improving the application's performance?

Caching of frequently accessed data.

Protocol optimization that reduces the number of round trips required for each request.

Increasing the WAN link bandwidth.

Compression of the application traffic.

Campus WAN Performance JN0-1103 Practice Questions (Page 4)

Part of the Campus and Branch WAN Design domain, which makes up ~33% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~12–20 in this domain), expect 1–2 from this objective — we provide 30 practice questions to prepare you well beyond it.
