Cisco 300-415 Online Questions & Answers

• Question 421:

  A network administrator is configuring a centralized control policy based on match action pairs for multiple conditions.

  Which order must be configured to prefer Prefix List over TLOC and TLOC over Origin?

  A. highest to lowest sequence number
  B. nonsequential order
  C. deterministic order
  D. lowest to highest sequence number
  D. lowest to highest sequence number

  ---

  Explanation

  By assigning higher sequence numbers to the rules or match action pairs you want to prioritize, you ensure that these rules are evaluated first. In this case, you would configure the Prefix List rule with a higher sequence number than the TLOC rule, and the TLOC rule with a higher sequence number than the Origin rule.

• Question 425:

  An administrator must configure an ACL for traffic coming in from the service-side VPN on a specific WAN device with circuit ID 391897770.

  Which policy must be used to configure this ACL?

  A. local data policy
  B. central data policy
  C. app-aware policy
  D. central control policy
  A. local data policy

  ---

  Explanation

  Localized data policy controls the flow of data traffic into and out of interfaces and interface queues on a vEdge router. This type of data policy is provisioned locally, on the vEdge router, 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.
