Cisco 300-415 Online Questions & Answers

• Question 221:

  Which component of the Cisco SD-WAN architecture oversees the control plane of overlay network to establish, adjust, and maintain the connections that form the Cisco SD-WAN fabric?

  A. APIC-EM
  B. vSmart
  C. vManage
  D. vBond
  B. vSmart

• Question 222:

  Two sites have one WAN Edge each. Each WAN Edge has two public TLOCs with no restrict configured. There is full reachability between the TLOCs. How many data tunnels are formed on each Edge router?

  A. 6
  B. 2
  C. 4
  D. 8
  C. 4

  ---

  By default, WAN Edge routers try to form an overlay tunnel to every TLOC over each available WAN transport, including TLOCs that belong to other colors if there is IP reachability between the two transport networks.

• Question 223:

  What is the role of the Session Traversal Utilities for NAT server provided by the vBond orchestrator?

  A. It facilitates SD-WAN toners and controllers to discover their own mapped or translated IP addresses and port numbers
  B. It prevents SD-WAN Edge routers from forming sessions with public transports among different service providers
  C. It facilitates SD-WAN Edge routers to stay behind a NAT-enabled firewall while the transport addresses of the SD-WAN controller are unNAT-ed
  D. It allows WAN Edge routers to form sessions among MPLS TLOCs using only public IP addresses
  A. It facilitates SD-WAN toners and controllers to discover their own mapped or translated IP addresses and port numbers

• Question 224:

  An engineer must configure local redundancy on a site. Which configuration accomplishes the task?

  A. vpn 0tloc-extension interface interface-name
  B. interface interface-name tloc-extension
  C. tloc-extension interface interface-name
  D. vpn 0interface interface-name tloc-extension interface-name
  D. vpn 0interface interface-name tloc-extension interface-name

  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 226:

  A customer requires reliability for voice traffic and has MPLS, biz-internet, and public-internet transports. Which control policy configuration maintains a better SLA and avoids blackholing of voice traffic?

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 227:

  Which software security feature is supported by the Cisco ISR 4451 router?

  A. IPsec/GRE cloud proxy
  B. reverse proxy
  C. Enterprise Firewall with Application Awareness
  D. Cloud Express service
  C. Enterprise Firewall with Application Awareness

• Question 228:

  What are the two reasons a customer chooses to use IPsec tunnels over GRE? (Choose two.)

  A. IPsec failure detection is faster.
  B. Generally, they provide a higher bandwidth for tunnel connection.
  C. CFlowd is required.
  D. A WAN Edge router is behind NAT.
  E. IPsec is more secure.
  A. IPsec failure detection is faster.
  E. IPsec is more secure.

• Question 229:

  An engineer configures an application-aware routing policy for a group of sites. The locations depend on public and private transports. The policy does not work as expected when one of the transports does not perform properly. This policy is configured:

  

  Which configuration completes the policy so that it works for all locations?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  ---

  Within the configured policy Realtime is being tagged with DSCP 46 which is voice and Transactional data is attached to DSCP 34 which is interactive video. Therefore, both of these 2 clases should have a lower amount of loss and jitter.

• Question 230:

  Which API call retrieves a list of all devices in the network?

  A. https://vmanage_IP_address/dataservice/system/device/{{model}}
  B. http://vmanage_IP_address/dataservice/system/device/{{model}}
  C. http://vmanage_IP_address/api-call/system/device/{{model}}
  D. https://vmanage_IP_address/api-call/system/device/{{model}}
  A. https://vmanage_IP_address/dataservice/system/device/{{model}}
