Cisco CCDE 400-007 Questions & Answers

• Question 291:

  A business wants to centralize services via VDI technology and to replace remote WAN desktop PCs with thin client-type machines to reduce operating costs.

  Which consideration supports the new business requirement?

  A. VDI servers should be contained centrally within a DMZ

  B. The thin client traffic should be placed in a WAN QoS priority queue

  C. VDI servers should be contained within dedicated VLANs in each branch location

  D. The WAN should offer low latency and be resized

  Correct Answer: D

• Question 292:

  Company XYZ plans to run OSPF on a DMVPN network. They want to use spoke-to-spoke tunnels in the design.

  What is a drawback or concern in this type of design?

  A. Additional host routes will be inserted into the routing tables

  B. Manual configuration of the spokes with the appropriate priority will be needed

  C. There will be split-horizon issue at the hub

  D. Manual configuration of the spoke IP address on the hub will be needed

  Correct Answer: B

• Question 293:

  A multinational enterprise integrates a cloud solution with these objectives

  Achieve seamless connectivity across different countries and regions Extend data center and private clouds into public clouds and provider-hosted clouds

  What are two outcomes of deploying data centers and fabrics that interconnect different cloud networks? (Choose two.)

  A. enhanced security

  B. data and network ownership

  C. ability to place workloads across clouds

  D. centralized visibility

  E. unidirectional workload mobility across the cloud

  Correct Answer: AC

• Question 294:

  A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN EVPN data center within the same location The networks are joined to enable host migration at Layer 2.

  What is the final migration step after hosts have physically migrated to have traffic flowing through the new network without changing any host configuration?

  A. Shut down legacy Layer 3 SVIs. clear ARP caches on all hosts being migrated and then configure the legacy VRRP address onto new VXLAN core switches

  B. Increase VRRP priorities on new infrastructure over legacy VRRP values, then shut down legacy SVIs

  C. Shut down legacy infrastructure to allow VXLAN gateways to become active

  D. Shut down legacy Layer 3 SVIs and activate new preconfigured Layer 3 SVIs on VXLAN

  Correct Answer: D

• Question 295:

  A software-defined networking (SDN) controller teams network topology information by using BGP link-state sessions with the route reflectors of an MPLS-enabled network. The controller then uses the topology information to apply on-demand traffic policies to the network through a protocol that is supported from all Layer 3 routers Each policy is represented as a RIB entry in the control plane of the router.

  Which SDN model has been implemented?

  A. SDN centralized

  B. SDN traffic engineering

  C. SD-WAN

  D. SDN hybrid

  Correct Answer: B

• Question 296:

  A business requirement is supplied to an architect from a car manufacturer stating their business model is changing to just-in-time manufacturing and a new network is required, the manufacturer does not produce all of the specific components m-house.

  Which area should the architect focus on initially?

  A. Automation

  B. Zero Trust Networking

  C. Low Latency Infrastructure

  D. Modularity

  Correct Answer: D

• Question 297:

  The Company XYZ network requires OSPF dead neighbor detection in a subsecond manner However the company network does not support BFD. Which other feature can be used to fulfill the design requirement?

  A. STP

  B. fast hello

  C. LFA

  D. DPD

  Correct Answer: B

• Question 298:

  Refer to the exhibit.

  B. Managed SD-WAN

  C. SD-WAN over L3VPN

  D. SD-WAN over L2VPN

  Correct Answer: B
