Exam 350-401 topic 1 question 44 discussion

Hi gents, here my thinking to this topic A. under traffic classification and marking conditions --> this is not a condition but rather an action and therefore WRONG B. under interface saturation conditions Saturation is a condition and NOT BAD C. under all network conditions well if this was the case, then the vendor Cisco would have made this a default state and thats it. also WRONG D. under network convergence conditions Well the wording is very vague here. a service policy can assign utmost priority to system level tasks that help in convergence, for example try putting OSPF protocol into CS6 or EF marking and implement a Priority Queueing (PQ) then you have made convergence faster but starved out everything else. Also NOT BAD but why would any clear thinking admin interfere with system level priorities? as far as i can see, there is only answer B which is NOT BAD answer for a question worded like that. Answer B

B is correct!

B is the correct answer

conditions!!!

it´s B

B is correct. Marking should be performed on inbound policies. Outbound policies are to allow for proper queueing to handle times of saturation.

A would be correct because consider traffic like VoIP, video, etc.

B. Under interface saturation conditions When the WAN interface is experiencing high utilization or saturation, an outbound QoS policy becomes especially useful. In such conditions, the link might be congested, leading to potential packet drops, latency, or degradation of critical traffic performance. Implementing QoS policies allows prioritization and control of traffic, ensuring that important applications or traffic types receive preferential treatment, minimizing the impact of congestion on critical services. QoS policies help manage and shape traffic leaving the interface, allowing network administrators to allocate bandwidth, prioritize certain types of traffic (such as voice or video), and mitigate congestion effects during periods of high utilization. This helps in maintaining better network performance and ensuring that essential applications or services continue to function optimally even under saturation conditions.

B is correct answer

b is correct

I think B is correct for me!!!

another stupidly phrased question. if the answer is really A, i think the question needs to be phrased like this: under which conditions will an outbound QoS policy be most beneficial. given this, it would be most beneficial if traffic was marked and classified first. If it wasnt marked or classified, then interface saturation would make no difference. But test makers are trying to craft words in a tricky way, resulting in B seeming like the best answer. I dunnow! dumb question. I hope I don't see this on the exam!

The congestion condition

MY SELECT CORRECT. SORRY

RUI OLEGARIO DE SIQUEIRA - VOT IS C

B is correct!

I agree with B.
