Which of the following statements are false about the router’s operations? (Select all that apply). The router encapsulates a new destination IP address before sending the data. The router removes the data frame header and checks the destination IP address. The router searches the IP routing table based on the port number in the transport layer header. The router checks the content of the application-layer data and determines the port from which to send the data.

On the network shown in the figure, GE1/0/1 and GE1/0/2 of SW1 are access interfaces, and their PVIDs are VLAN 2 and VLAN 3 respectively. GE1/0/1 of SW2 is also an access interface, and its PVID is VLAN 4.

Configure GE1/0/3 of SW1 as a hybrid interface, add it to VLAN 2 and VLAN 3 in untagged mode, and set its PVID to VLAN 4. Configure GE1/0/3 of SW2 as a trunk interface, configure it to allow packets from VLAN 4 to pass through, and set its PVID to VLAN 4.

Four links between two switches establish an Eth-Trunk in manual mode, and the bandwidth of each link is 1 Gbit/s. One of the links fails. Which of the following statements are true about this scenario? (Select all that apply). The Eth-Trunk interfaces on the switches are still in the Up state. The available link bandwidth between the switches is 3 Gbit/s. The service traffic originally carried by the faulty link stops being forwarded by the switches until the faulty link recovers. All TCP sessions established over the Eth-Trunk are immediately interrupted and re-established.

On the network shown in the figure, the administrator creates Eth-Trunk 1 in manual mode on SW1 and SW2, and adds GE1/0/1 and GE1/0/2 on both switches to the Eth-Trunk. After the administrator runs the display interface brief command on SW1, the administrator finds that GE1/0/1 is Up and GE1/0/2 is Down. Which of the following statements is true about this scenario? ----> GE1/0/1 G1/0/1----> SW1<----- <----- SW2 -----> GE1/0/2 G1/0/2---->. Eth-Trunk 1 is Up because it is Up as long as one member interface is Up. Eth-Trunk 1 is Down because the states of member interfaces must be the same in manual mode. Eth-Trunk 1 is Down because it has only two member interfaces and the minimum number of active links is not reached after one member interface is Down. Eth-Trunk 1 is Down because all member interfaces of the Eth-Trunk must be Up.

The administrator configures an Eth-Trunk in LACP mode between two switches, and sets the maximum number of active links in the Eth-Trunk to 3 and the number of remaining standby links to 1. If one of the active links fails, the two switches automatically adjust the number of active links to 2 through negotiation, and the standby link remains in the standby state. TRUE. FALSE.

After receiving the data frame sent from PC1 to PC2, SW1 adds the VLAN 10 tag to the data frame and then accepts the data frame. SW1 accepts the data frame sent from PC1 to PC2, but discards the data frame returned from PC2 to PC1. The data frame processed inside SW1 does not carry any VLAN tag. SW1 removes the VLAN 10 tag from the data frame before forwarding it from GE1/0/2 to PC2.

Set a lower port priority on SW2. Set a higher system priority on SW2. Set a lower system priority on SW2. Set a lower root path cost on SW2.

The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds. The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1. Then, the administrator disconnects the Ethernet cable of PC1 from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1? GE1/0/3 [SW1] ----------------------- [SW2] | | | GE1/0/1 | GE1/0/1 | | [PC1] [PC2] IP: 192.168.1.1/24 IP: 192.168.1.2/24 MAC: 0050-5600-0001 MAC: 0050-5600-0002 \ \ GE1/0/2 (ligação tracejada) \ [PC1] IP: 192.168.1.1/24 MAC: 0050-5600-0001. SW1 saves the mapping between the MAC address of PC1 and GE1/0/1, and also keeps the mapping between the MAC address of PC1 and GE1/0/2. SW1 saves the mapping between the MAC address of PC1 and GE1/0/2 and deletes the mapping between the MAC address of PC1 and GE1/0/1. SW1 deletes all MAC address entries and relearns them from all ports. SW1 does not update the MAC address table until the original entry ages out.

On the switched network shown in the figure, STP is enabled on all devices. SW1 is the root bridge. The port costs are shown in the figure. Other parameters retain the default values. After the network is stable, which of the following paths is used by SW1 to send traffic to SW4?

The emergence of AI poses new requirements on data center networks. To meet AI computing requirements, a high-speed intelligent computing data center network with zero packet loss needs to be constructed. Which of the following statements are false about the requirements and solutions of intelligent computing data center networks? (Select all that apply). Measures such as single-port ultra-high bandwidth and lossless network technologies can be used to achieve a network with close to zero packet loss, but not a truly lossless network. Lossless technologies such as PFC and ECN are used on the intelligent computing network to implement a network with zero packet loss. Due to large-scale data synchronization services on the intelligent computing network, a single port must have a high bandwidth, such as 200GE or 400GE. The RDMA protocol stack is used on the intelligent computing network to reduce the transmission latency between GPU servers and physical switches.

With the continuous development of AI, data center application scenarios are gradually divided into general-purpose computing and intelligent computing scenarios. Data centers need to ensure service continuity of general-purpose computing clusters while unleashing the full potential of intelligent computing clusters, so as to guarantee stable and efficient operation in the AI era. Which of the following statements are true about the service requirements of data center networks in the two scenarios? (Select all that apply). The general-purpose computing network demands a well-defined hierarchy, adopting a core aggregation-access three-layer architecture. The general-purpose computing network requires high network stability and efficiency. Technologies such as M-LAG can be used to implement fast failover, and VXLAN can be deployed to build a large Layer 2 network for VM migration. The intelligent computing network requires zero packet loss, which necessitates the deployment of various lossless network technologies such as PFC and ECN. The intelligent computing network requires ultra-low latency, including the latency of data transmission within a compute node. The latency can be further reduced by using the RoCE protocol.

With the development of data centers, a large number of services are deployed on virtual machines (VMs). The original VLAN isolation solution cannot achieve isolation between so many VMs. VXLAN uses VXLAN Network Identifiers (VNIs) to provide a larger range than VLAN IDs, so that a larger number of VMs can be isolated.

Both SNMP Trap and Inform Request are used by managed devices to send alarms to the NMS. Inform Request requires an acknowledgment from the NMS, whereas Trap does not. TRUE. FALSE.

During WLAN deployment, a Fit AP fails to go online on the WAC. You log in to the WAC and run the display ap online-fail-record command to locate the fault. The command output shows that the cause is Insufficient license resources. This means that the license resources on the WAC are insufficient and that you need to expand the license capacity. TRUE. FALSE.

.On the campus network shown in the figure below, the core switch Core1 functions as a Layer 3 gateway and as a DHCP server to dynamically assign IP addresses to AP1, PC1, PC2, and PC3. The network below Core1 is a Layer 2 network. WAC1 and R1 are connected to Core1 at Layer 3. AP1 goes online through VLAN 100. The wireless service VLAN is VLAN 101, and the wired service VLANs for PC2 and PC3 are VLAN 102 and VLAN 103, respectively. Additionally, the direct forwarding mode is used for wireless traffic forwarding. If no additional VLANs are allowed on device interfaces, which of the following VLANs must be allowed on GE1/0/1 of ACC1? (Select all that apply) [Internet] | GE0/0/1 | [R1] | GE0/0/2 | Interconnection VLAN 10 | GE1/0/1 [Core1] _________|___________ | | GE1/0/2 GE1/0/4 | | [ACC1] [ACC2] / \ | / \ | MultiGE0/0/0 GE1/0/2 GE1/0/2 | | | [AP1] [PC2] [PC3] | [PC1]. VLAN 100. VLAN 101. VLAN 102. VLAN 200.
