Cisco CCDE 400-007 Questions & Answers

• Question 241:

  Company XYZ branch offices connect to the headquarter sites using two links, MPLS and Internet. The company wants to design the traffic flow so that voice traffic goes through the MPLS link and all other traffic uses either the MPLS link or the Internet link. Which technique can the company use in their design to ensure that the traffic is not process switched?

  A. policy-based routing

  B. virtual links

  C. visualization

  D. floating static route

  Correct Answer: A

• Question 242:

  Which extensions to GRE tunneling provide session tracking and in-order packet delivery in exchange for additional state stored in tunnel endpoints?

  A. GRE Protocol Type and Checksum extension fields.

  B. GRE Version and Reserved0 extension fields.

  C. No extension fields are available in the GRE header to track session data and packet sequences.

  D. GRE Key and Sequence number extensions.

  Correct Answer: D

• Question 243:

  Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future.

  Which technology can be used to meet these requirements?

  A. multipoint route-redistribution with route filtering using ACLs

  B. DUMP multipoint route-redistribution with route filtering using route tags

  C. DUMPS single point route-redistribution with route filtering using route tags

  D. DUMPS single point route-redistribution with route filtering using ACLs

  Correct Answer: B

• Question 244:

  A senior network designer suggests that you should improve network convergence times by reducing BGP timers between your CE router and the PE router of the service provider. Which two factors should you consider to adjust the timer values? (Choose two.)

  A. service provider agreement to support tuned timers

  B. manual updates to the peer groups

  C. service provider scheduling of changes to the PE

  D. number of routes on the CE router

  E. number of VRFs on the PE router

  Correct Answer: AD

• Question 245:

  Which undesired effect of increasing the jitter compensation buffer is true?

  A. The overall transport jitter decreases and quality improves.

  B. The overall transport jitter increases and quality issues can occur.

  C. The overall transport delay increases and quality issues can occur.

  D. The overall transport delay decreases and quality improves.

  Correct Answer: C

• Question 246:

  Which two mechanisms avoid suboptimal routing in a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries? (Choose two.)

  A. AD manipulation

  B. matching OSPF external routes

  C. route tagging

  D. route tagging

  E. route filtering

  F. matching EIGRP process ID

  Correct Answer: AD

  To solve this type of problem, the redistributing routers must have some awareness of which routes came from the other routing domain. In particular, the lower-AD routing protocol needs to decide which routes came from the higher-AD routing protocol, and either use a different AD for those routes or filter the routes.

• Question 247:

  Which two benefits can software defined networks provide to businesses? (Choose two.)

  A. provides additional redundancy

  B. decentralized management

  C. reduced latency

  D. enables innovation

  E. reduction of OpEx/CapEx

  F. meets high traffic demands

  Correct Answer: DE

• Question 248:

  Refer to the diagram.

  

  Which solution must be used to send traffic from the foreign wireless LAN controller to the anchor wireless LAN controller?

  A. Send packets from the foreign controller to the anchor controller via Layer 3 MPLS VPN or VRF-Lite

  B. Send packets without encapsulation to the anchor controller over the routed network.

  C. Encapsulate packets into an EoIP tunnel and send them to the anchor controller.

  D. Send packets from the foreign controller to the anchor controller via IPinIP or IPsec tunnel.

  Correct Answer: C

• Question 249:

  Which two pain points are the most common for container technology adoption? (Choose two)

  A. Performance

  B. Security

  C. Cost

  D. Container deployment

  E. Skilled staff

  F. Compliance

  Correct Answer: DE

  What is one topic that should be considered in the Define Strategy step?

  A. financial and governance models

  B. innovate and align with business according to volume

  C. due diligence and financial scenarios

  D. contingency exit strategy steps

  Correct Answer: D
