Cisco Exam 300-415 Topic 5 Question 94 Discussion

Actual exam question for Cisco's 300-415 exam

Question #: 94
Topic #: 5

An application team is getting ready to deploy a new business-critical application to the network. To protect the traffic, the network team must add another queue to the QoS map and then deploy the map to fabric Which configuration slop must be completed prior to adding the queue to the QoS map and applying If

AThe relationship between die new QoS class and the hardware queue must be configured from the 'lists' page of the Local Policy section of vManage. The QoS map is then applied to the WAN interface

BThe relationship between The new QoS class and the hardware queue must be configured from the 'lists' page of the Local Policy section of vManage. The QoS map is then applied to the service-side interface.

CThe relationship between the new QoS class and the hardware queue must be configured from the 'lisla' page of the Centralized Policy section of vManage. The QoS map is then applied to the WAN interface.

DThe relationship between the new QoS class and the hardware queue must be configured from the 'lists' page of the Centralized Policy section of vManage. The QoS map is then applied to the service-side interface.

Show Suggested Answer

Suggested Answer: A

Adding a new QoS queue to handle business-critical application traffic involves several specific steps in Cisco SD-WAN's vManage:

1.Configure QoS Class and Hardware Queue Relationship:

oNavigate to the 'lists' page within the Local Policy section of vManage.

oDefine the relationship between the new QoS class and the appropriate hardware queue. This step is crucial as it ensures that the new traffic class is mapped correctly to the underlying hardware resources, which are responsible for enforcing the QoS policies.

1.Applying the QoS Map:

oOnce the new QoS class and hardware queue relationship is configured, the updated QoS map must be applied to the relevant interfaces.

oSpecifically, the QoS map should be applied to the WAN interface. This ensures that the new QoS policies are enforced on the traffic as it traverses the WAN, which is typically where QoS management is most critical due to bandwidth constraints and variable network conditions.

I'm really feeling option A on this one. The 'lists' page of the Local Policy section is where you set up the QoS class-to-hardware queue mapping, and then you apply it to the WAN interface. Easy peasy!

Ah, I see what they're getting at. This is a tricky one, but I'm going with B. The key is that it's the 'Local Policy' section, not the 'Centralized Policy' section.

Hmm, I think C is the correct answer. The relationship between the new QoS class and the hardware queue must be configured from the 'lists' page of the Centralized Policy section of vManage, and then the QoS map is applied to the WAN interface.

Yes, that's correct. Once that's done, the QoS map can be applied to the WAN interface for the new business-critical application deployment.

I agree, C seems to be the right choice. It's important to configure the relationship between the QoS class and hardware queue from the Centralized Policy section of vManage.
