Exam 350-401 topic 1 question 50 discussion

The Cisco SD-WAN architecture implements two types of data policy: Centralized data policy controls the flow of data traffic based on the source and destination addresses and ports and DSCP fields in the packet's IP header (referred to as a 5-tuple), and based on network segmentation and VPN membership. These types of data policy are provisioned centrally, on the Cisco vSmart controller, and they affect traffic flow across the entire network. Localized data policy controls the flow of data traffic into and out of interfaces and interface queues on a Cisco vEdge device. This type of data policy is provisioned locally using access lists. It allows you to classify traffic and map different classes to different queues. It also allows you to mirror traffic and to police the rate at which data traffic is transmitted and received.

a set of statements define how data is forwarded based on source and destination (IP packet information)

B is correct

If you search in the official guide about "data policy" you will never find a result -_- why is this question in the exam then !!

B is correct

Ref: Policies Configuration Guide for vEdge Routers, Cisco SD-WAN Releases 19.1, 19.2, and 19.3 “C H A P T E R 2 Policy Basics … Policy Overview Policy influences the flow of data traffic and routing information among Cisco vEdge devices in the overlay network. Policy comprises: … • Data policy—which affects the flow of data traffic in the network's data plane …” A. list of ordered statements that define node configurations and authentication used within the SD-WAN overlay Wrong answer. B. set of statements that defines how data is forwarded based on IP packet information and specific VPNs Correct answer. C. detailed database mapping several kinds of addresses with their corresponding location Wrong answer. D. group of services tested to guarantee devices and links liveliness within the SD-WAN overlay Wrong answer.

it is B

B! It is definitely a forwarding policy

hi folks, here is my opinion this matter. https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/policies/vedge/policies-book/data-policies.html "Data policy can be applied to data traffic based on the packet header fields, such as the prefix, port, protocol, and DSCP value, and they can also be applied based on the VPN in the overlay network to which the traffic flows." Answer: B

Provided answer is correct

B is the correct answer. https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/config-guide/b_wl_16_10_cg/mobility.html
