                                                  質問 # 184
                                                  A network becomes unintentionally segmented when remote sites connect to HQ only via the public Internet.
                                                  Which option helps de-segment the network?

                                                  正解：A

                                                  解説：
                                                  # Explanation:
                                                  A: Virtual networks (e.g., VPNs, tunnels) create secure, logical overlays across segmented physical infrastructure such as the public Internet, effectively re-integrating remote sites into the corporate network.
                                                  This re-establishes end-to-end connectivity and consistent routing/security policies.
                                                  Other options:
                                                  B: QoS does not address segmentation or connectivity.
                                                  C: Lax control-plane policies do not restore logical network integration and may increase security risk.
                                                  D: Blocking traffic further limits connectivity and exacerbates segmentation.

                                                  質問 # 185
                                                  Refer to the exhibit.

                                                  An engineer is designing the traffic flow for AS 111. Traffic from AS 111 should be preferred via AS 100 for all external routes. A method must be used that only affects AS 111. Which BGP attributes are best suited to control outbound traffic?

                                                  正解：B


                                                  質問 # 186
                                                  When classifying and marking traffic, a recommended design principle is to classify and mark applications as close to their sources as technically and administratively feasible. As the line between enterprises and service providers continues to blur, what ensures interoperability and future expansion?

                                                  正解：B


                                                  質問 # 187
                                                  Refer to the exhibit.

                                                  Refer to the exhibit. A new high availability DB server cluster is installed in the network. These two servers require high bandwidth and low latency Layer 2 connectivity for database replication.
                                                  Which solution supports these requirements?

                                                  正解：D

                                                  解説：
                                                  To support high-bandwidth, low-latency Layer 2 communication between DB Server 1 and DB Server 2, you must create a direct Layer 2 path between SW1 and SW2. Using REP (Resilient Ethernet Protocol) segments ensures loop-free Layer 2 operation without the drawbacks of STP convergence delays.
                                                  * Option C is correct: Adding a third REP segment (Segment 3) directly between SW1 and SW2 isolates the traffic between the two DB servers and ensures deterministic behavior with fast convergence.
                                                  * Option A (LACP with STP) introduces STP blocking and doesn't align well with REP's control plane.
                                                  * Option B and D: Overloading existing segments or splitting new links into existing REP segments does not offer the same direct path, bandwidth, or deterministic behavior.


                                                  質問 # 188
                                                  Drag and drop the FCAPS network management reference models from the left onto the correct definitions on the right.

                                                  正解：

                                                  解説：


                                                  質問 # 189
