                                          問題 #181
                                          The network logic architecture of a cutover project is shown in the figure. The purpose of the cutover is to expand a network device R4 between R2 and R3. The router IDs of R1, R2, and R3 are 10.0.1.1, 10.0.2.2, and 10.0.3.3 respectively. The OSPF protocol runs between network devices.

                                          After the physical network is connected, when performing the cutover operation, the network engineer first mistakenly imports the backup configuration of R3 into R4. Based on this scenario, which of the following descriptions are correct? (Multiple choice)

                                          答案：C,D


                                          問題 #182
                                          Which of the following statements about VLAN aggregation is true?

                                          答案：B,D


                                          問題 #183
                                          In BGP/MPLS IP VPN, the OSPF multi-instance process uses the DN bit to prevent Type5 LSA loops.

                                          答案：A


                                          問題 #184
                                          A network engineer provides a troubleshooting report after rectifying a fault. The actual network is simplified into the one shown in the figure, where R1 and R2 both have OSPF enabled, and function as the gateways of PCI and PC2, respectively. Given this, which of the following statements is false?

                                          答案：C


                                          問題 #185
                                          On the network shown in the figure, PC1 and PC2 are connected to the same switch (SW1) and belong to the same VLAN.

                                          Which of the following are possible causes of a communication failure between PC1 and PC2?
                                          Options:

                                          答案：A,B,C,D

                                          解題說明：
                                          Comprehensive and Detailed In-Depth Explanation:
                                          1. Understanding the Network Setup
                                          * PC1 (192.168.1.1/24) and PC2 (192.168.1.2/24) are connected to SW1.
                                          * Both PCs are in the same VLAN, meaning communication should work without routing.
                                          * If there is a communication failure, it could be due to physical, VLAN, ARP, or port security issues.
                                          2. Evaluating Each Answer Option
                                          * Option A: "SW1's GE0/0/2 is shut down."
                                          * Correct.
                                          * If GE0/0/2 is shut down, PC2 cannot send or receive traffic, causing communication failure.
                                          * Even if PC1 is working, PC2 will be unreachable.
                                          * # A is a valid cause.
                                          * Option B: "The link of SW1's GE0/0/1 is faulty."
                                          * Correct.
                                          * If GE0/0/1 has a faulty link, PC1 cannot communicate with PC2, causing failure.
                                          * Even if PC2 is working, PC1 will be unreachable.
                                          * # B is a valid cause.
                                          * Option C: "Incorrect static ARP entries are configured on the hosts."
                                          * Correct.
                                          * If static ARP entries are incorrectly configured, PCs will map the wrong MAC addresses to IPs.
                                          * This will result in packet delivery failures, even if the physical network is working.
                                          * # C is a valid cause.
                                          * Option D: "Port isolation is configured on SW1."
                                          * Correct.
                                          * Port isolation (or private VLAN) prevents direct communication between specific ports.
                                          * If port isolation is enabled on GE0/0/1 and GE0/0/2, PC1 and PC2 will be unable to reach each other.
                                          * # D is a valid cause.
                                          Final Answer:
                                          # A, B, C, and D are correct.
