Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 249

Under which network conditions is an outbound QoS policy that is applied on a router WAN interface most beneficial?

Answer options

• A. under traffic classification and marking conditions
• B. under interface saturation conditions
• C. under all network conditions
• D. under network convergence conditions

Correct answer: B

Explanation

An outbound QoS policy is most beneficial under interface saturation conditions because it helps prioritize traffic and manage bandwidth effectively when the network is congested. The other options, such as traffic classification and marking, network convergence, and all network conditions, do not necessarily indicate a need for QoS adjustments, as they may not involve immediate bandwidth concerns.
