What is the first step in troubleshooting a WAN performance degradation issue?

Identify the affected applications and time frame

A campus is planning a new WAN link to a remote site. The site has 200 users who primarily use email, web browsing, and a cloud-based CRM. The average concurrent bandwidth usage is estimated at 80 Mbps, with peaks of 120 Mbps during daily backups. The business requires that the CRM remain responsive during peak times. What is the most appropriate link capacity planning approach?

Provision a 80 Mbps link and schedule backups outside business hours.

Provision a 100 Mbps link and rely on QoS to prioritize CRM traffic during peaks.

Provision a 200 Mbps link to ensure no congestion ever occurs.

Provision a 150 Mbps link to accommodate the peak usage with some headroom.

A network architect is designing a WAN link for a campus that will run a mix of real-time and data traffic. The architect must choose between a single high-bandwidth link and two lower-bandwidth links with load balancing. Which factor is most important to consider for the real-time traffic?

The total bandwidth of the links.

The potential for jitter introduced by load balancing.
