                                          質問 # 280
                                          An engineer must design a management network that enables SSH, NTP, FTP, and SNMP over the production network. The design requires the management of routers and switches that exist across different networks. Which feature must the design include?

                                          正解：A

                                          解説：
                                          A dedicated management VRF is the correct feature when management protocols must traverse the production network but remain logically separated. The question describes in-band management because SSH, NTP, FTP, and SNMP are carried over the production network rather than over a separate physical console or out- of-band network. The design still requires routers and switches across different networks to be managed securely. A management VRF gives the management plane its own routing table, allowing the engineer to restrict management reachability, apply separate routing, and keep management traffic from leaking into user or service forwarding paths. Management Plane Protection can restrict which interfaces accept management- plane traffic, but it does not by itself provide separate routing across different networks. A terminal server or dedicated console connection is an out-of-band operational tool, not the production-network management design requested here. A dedicated management VRF per device is therefore the correct feature. Reference topics: in-band management, management VRF, SNMP and SSH reachability, management-plane segmentation, enterprise operations design.


                                          質問 # 281
                                          An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network. The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same router levels for each protocol per interface. Which IS-IS design is required?

                                          正解：D

                                          解説：
                                          https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_isis/configuration/xe-3s/irs-xe-3s-book/ip6-route-isis-xe.html#GUID-04990BCF-8228-459E-AFAA-9FAF1E2136E9 For single-topology IS-IS IPv6, routers must be configured to run the same set of address families. IS-IS performs consistency checks on hello packets and will reject hello packets that do not have the same set of configured address families. For example, a router running IS-IS for both IPv4 and IPv6 will not form an adjacency with a router running IS-IS for IPv4 or IPv6 only. In order to allow adjacency to be formed in mismatched address-families network, the adjacency-check command in IPv6 address family configuration mode must be disabled.


                                          質問 # 282
                                          Drag and drop the model-driven telemetry considerations from the left onto the modes they apply to on the right.

                                          正解：

                                          解説：


                                          質問 # 283
                                          An engineer is configuring an interface on a Cisco IOS XE device using a RESTCONF PATCH request. The target data model requires a strict hierarchy containing the correct namespace, container paths, list keys, and leaf values.Refer to the exhibit. Which JSON payload accurately represents the expected YANG data model structure to successfully commit the configuration?

                                          正解：A

                                          解説：
                                          The validated answer is Option D because this item depends on the exhibit containing configuration or model fragments. In Cisco programmability questions, the correct option is determined by whether the selected YANG or API payload accurately represents the intended configuration hierarchy, data types, and device- specific path. The answer must match the complete model structure, not merely contain the right-looking address, interface name, or protocol value. Option D should therefore be retained as the verified selection because it is the only option that aligns with the expected data model structure shown in the exhibit. For these items, the professional review must avoid inventing a replacement payload when the answer choices are embedded as images. The proper explanation is that YANG-based configuration validation requires the namespace, container path, list keys, and leaf values to match the model used by the target platform.
                                          Reference topics: YANG configuration validation, RESTCONF or NETCONF payload structure, model hierarchy, Cisco IOS XE programmability, exhibit-based option verification.


                                          質問 # 284
                                          An architect must address sustained congestion on the access and distribution uplink of network.
                                          QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal network performance.
                                          Which two solutions should the architect use to improver network performance? (Choose two)

                                          正解：B、E


                                          質問 # 285
