Questions # 101:

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

Options:

The 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

The 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.

The 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.

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. The QoS map is then applied to the service-side interface.

Answer

Explanation

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

Configure QoS Class and Hardware Queue Relationship:

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

Define 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.

Applying the QoS Map:

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

Specifically, 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.

Questions # 105:

Question # 105

An engineer configures Rome WAN Edge 10 use MPLS cloud as the preferred link to reach Paris WAN Edge and use biz-internet as a backup. Which policy configuration must be led in the outbound direction toward Rome to accomplish the task?

Question # 105

Options:

Option A

Option B

Option C

Option D

Answer

Explanation

To configure Rome WAN Edge to prefer the MPLS cloud for reaching Paris WAN Edge, and use biz-internet as a backup, the policy must be set correctly to define the preference for each transport link.

Understanding TLOCs (Transport Locator): TLOCs represent the transport network paths (MPLS, Internet, etc.) available for SD-WAN. The preference values assigned to TLOCs determine their priority. A lower preference value indicates a higher priority.

Policy Configuration Analysis:

Option A: This option correctly configures the TLOC list for the system IPs representing the MPLS and biz-internet links with the appropriate preferences (500 for MPLS and 400 for biz-internet).

Other options either repeat the TLOC configuration incorrectly or reference wrong system IPs.

Policy Configuration:

policy

lists

tloc-list TLOC-1

tloc 10.1.1.102 color mpls encap ipsec preference 500

tloc 10.1.1.102 color biz-internet encap ipsec preference 400
