Cisco 300-415 Online Practice Questions and Exam Preparation

Cisco 300-415 Online Questions & Answers

• Question 431:

  Which condition must be present to support DRE in a Cisco SD-WAN environment?

  A. client-server topology
  B. TCP Optimization
  C. hub-and-spoke topology
  D. flow symmetry
  D. flow symmetry

• Question 432:

  A policy is created to influence routing in the network using a group of prefixes.

  What policy application will achieve this goal when applied to a site list?

  A. Vpn-membership policy
  B. Control-policy
  C. cflowd-template
  D. App-route policy
  B. Control-policy

• Question 433:

  How must the application-aware enterprise firewall policies be applied within the same WAN Edge router?

  A. within zone pair
  B. within and between zones
  C. between two VPN tunnels
  D. between two VRFs
  B. within and between zones

  ---

  Explanation

  Zones in this context refer to logical groupings of network interfaces or subnets on the WAN Edge router. By applying firewall policies within a zone, you control the traffic within that zone, and by applying policies between zones, you can control the traffic that flows between different zones. This allows for fine-grained control over network traffic and security.

• Question 434:

  Which two architectural components are part of an SD-WAN high availability vManage cluster? (Choose two.)

  A. network configuration system
  B. WAN Edge router
  C. NAT router
  D. messaging server
  E. application server
  A. network configuration system
  E. application server

• Question 435:

  An engineer is configuring a data policy for packets that must be captured through the policy.

  Which command accomplishes this task?

  A. policy > data-policy > vpn-list > sequence > default-action > drop
  B. policy > data-policy > vpn-list > sequence > action
  C. policy > data-policy > vpn-list > sequence > default-action > accept
  D. policy > data-policy > vpn-list > sequence > match
  B. policy > data-policy > vpn-list > sequence > action

• Question 436:

  An engineer wants to track tunnel characteristics within a SLA-based policy for convergence.

  Which policy configuration will achieve this goal?

  A. Data policy
  B. Control policy
  C. App-route policy
  D. VPN membership policy
  C. App-route policy

  ---

  Explanation

  App-Route policies allow you to define and manage application-aware routing policies based on specific application characteristics, such as application performance, latency, and other tunnel-related characteristics. These policies are used to ensure that traffic is routed over the most suitable paths to meet SLA (Service Level Agreement) requirements, including convergence and performance criteria.

• Question 437:

  Which type of lists are used to group related items via an application-aware routing policy under the policy lists command hierarchy on vSmart controllers?

  A. data prefix, she. and VPN
  B. OSCP value, application, and VPN
  C. data prefix, application, and SLA class
  D. DSCP value, site, and VPN
  C. data prefix, application, and SLA class

• Question 438:

  What are two attributes of vRoute? (Choose two)

  A. originator
  B. service
  C. encapsulation
  D. carrier
  E. domain ID
  A. originator
  B. service

• Question 439:

  What does forward error correction addresses in Cisco SO-WAN?

  A. inefficient traffic forwarding caused oy inbound shapers
  B. reduced application performance degradation rotated to service degradation
  C. applications with occasional invalid data input and poor performance
  D. traffic flows with increased delay over a particular transport
  B. reduced application performance degradation rotated to service degradation

• Question 440:

  For data plane resiliency, what does the Cisco SD-WAN software implement?

  A. BFD
  B. establishing affinity between vSmart controllers and WAN Edge routers
  C. multiple vBond orchestrators
  D. OMP
  A. BFD

  ---

  Explanation

  For data plane resilience, the Cisco SD-WAN software implements standard protocol mechanisms, specifically BFD, which runs on the secure IPsec tunnels between WAN Edge routers.
