                                                  Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q317-Q322):

                                                  NEW QUESTION # 317
                                                  The network designer needs to use GLOP IP addresses to make them unique within their ASN. Which multicast address range will be considered?

                                                  Answer: B

                                                  Explanation:
                                                  * C: GLOP addressing is defined in RFC 2770, assigning a portion of the 233.0.0.0/8 range for each AS based on their 16-bit ASN. This allows each AS to use a /24 of globally unique multicast addresses without coordination from IANA.
                                                  Other options:
                                                  * A: 239.0.0.0/8 is the administratively scoped multicast address space.
                                                  * B: 224.0.0.0/24 is reserved for local link-scoped protocols (e.g., OSPF, RIP).
                                                  * D: 232.0.0.0/8 is the Source-Specific Multicast (SSM) range.


                                                  NEW QUESTION # 318
                                                  Which type of interface are OpenFlow and OpFlex?

                                                  Answer: C

                                                  Explanation:
                                                  #Explanation:
                                                  * A: OpenFlow and OpFlex are examples of southbound interfaces in SDN (Software Defined Networking). They are used by the SDN controller to communicate with the underlying infrastructure (e.g., switches, routers, hypervisors).
                                                  Other options:
                                                  * D (Northbound): Interfaces used by applications to communicate with the SDN controller.
                                                  * B, C: Not standard terminologies in SDN interface classification.


                                                  NEW QUESTION # 319
                                                  Which issue poses a challenge for security architects who want end-to-end visibility of their networks?

                                                  Answer: D


                                                  NEW QUESTION # 320
                                                  An engineer is designing a DMVPN network where OSPF has been chosen as the routing protocol A spoke-to-spoke 'J<ita propagation model must be set up Which two design considerations must be taken into account? (Choose two )

                                                  Answer: C,E

                                                  What is the best approach in a large legacy application migration scenario when the goal is to complete the migration in the shortest possible time?

                                                  Answer: C

                                                  Explanation:
                                                  Rehosting, also known as "lift and shift," is the fastest migration approach because it moves the application to the cloud with minimal or no modifications, making it ideal when the priority is completing the migration quickly.
