Overall, the Cisco 400-007 exam is a challenging but rewarding certification exam that can help individuals take their career to new heights in the field of network design.
The CCDE v3.0 certification is designed for professionals who have extensive experience in network design and architecture. Cisco Certified Design Expert (CCDE) Written Exam certification validates the ability of a network designer to create advanced network solutions that meet the business requirements of organizations. The Cisco 400-007 Certification Exam is one of the requirements for obtaining the CCDE v3.0 certification.
Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q302-Q307):NEW QUESTION # 302
Company XYZ is designing the network for IPv6 security and they have these design requirements:
* A switch or router must deny access to traffic from sources with addresses that are correct, but are topologically incorrect
* Devices must block Neighbor Discovery Protocol resolution for destination addresses that are not found in the binding table.
Which two IPv4 security features are recommended for this company? (Choose two)
  • A. IPv6 Destination Guard
  • B. IPv6 Prefix Guard
  • C. IPv6 RA Guard
  • D. IPv6 Source Guard
  • E. IPv6 DHCP Guard
Answer: A,B

NEW QUESTION # 303
What is an architectural framework created by ETSI that defines standards to decouple network functions from proprietary hardware-based appliances and have them run in software on standard x86 servers?
  • A. NFV
  • B. NPIV
  • C. VNF
  • D. NFVIS
Answer: A
Explanation:
* C (NFV - Network Functions Virtualization):ETSI NFV framework allows virtualizing network functions (firewalls, load balancers, etc.) on standard hardware, promoting flexibility, cost reduction, and hardware independence.
Other options explained:
* A: NPIV relates to Fibre Channel storage, not network virtualization.
* B: NFVIS is Cisco's NFV infrastructure software, not the ETSI standard itself.
* D: VNF refers to individual virtualized functions, not the framework.

NEW QUESTION # 304
Company XYZ is revisiting the security design for their data center because they now have a requirement to control traffic within a subnet and implement deep packet inspection. Which technology meets the updated requirements and can be incorporated into the design?
  • A. VLAN ACLs on the switch
  • B. Zone-based firewall on the Layer 3 device
  • C. Routed firewall
  • D. Transparent firewall
Answer: D
Explanation:
* C (Transparent firewall): Operates at Layer 2, allowing filtering and inspection of traffic within the same subnet without requiring IP routing changes. It performs deep packet inspection while maintaining Layer 2 adjacency, making it ideal for intra-subnet traffic control in data centers.
* This allows security segmentation inside broadcast domains, enforcing security policies even for east- west traffic.
Other options explained:
* A: Routed firewalls require subnet boundaries and are not ideal for intra-subnet control.
* B: VLAN ACLs provide basic filtering but lack deep packet inspection capabilities.
* D: Zone-based firewalls are primarily designed for inter-subnet (Layer 3) traffic segmentation.

NEW QUESTION # 305
Company XYZ was not satisfied with the reconvergence time OSPF is taking. BFD was implemented to try to reduce the reconvergence time, but the network is still experiencing delays when having to reconverge. Which technology will improve the design?
  • A. Change the OSPF hello and dead intervals
  • B. OSPF fast hellos
  • C. Change the protocol to BGP
  • D. BFD echo
Answer: D
Explanation:
* B (BFD Echo):BFD Echo mode uses local hardware-based loopback mechanisms for even faster fault detection than regular BFD asynchronous mode, significantly reducing failure detection time and thus convergence delay.
Other options explained:
* A/D: OSPF fast hellos improve OSPF detection but are still control-plane driven and slower than hardware-based BFD Echo.
* C: BGP is slower to converge than OSPF, especially for IGP-like designs.

NEW QUESTION # 306
Which actions are performed at the distribution layer of the three-layer hierarchical network design model?
(Choose two)
  • A. Fast transport
  • B. Fault isolation
  • C. Redundancy and load balancing
  • D. Reliability
  • E. QoS classification and marking boundary
Answer: B,C
