Drag and Drop Question
On the network shown in the figure, the administrator creates an Eth-Trunk between SW1 and SW2 to increase link bandwidth and enable terminals in VLAN 10 and VLAN 20 to communicate with each other. When the network is running, the administrator encounters network problems.
Match the problems with the troubleshooting methods.

Match the problems with the troubleshooting methods.
Correct Answer:
Explanation:
GE1/0/3 added to the Eth-Trunk is always in Down state. -> Run the display interface brief command to check the status and error statistics of physical interfaces.
The traffic sent from PC1 cannot reach PC3 after passing through the Eth-Trunk. -> Check whether the lists of allowed VLANs on the Eth-Trunk interfaces at both ends are the same.
The Eth-Trunk cannot be established between the two devices. -> Check whether the aggregation modes at both ends of the Eth-Trunk match.
Physical Interface Down: When a single member port (GE1/0/3) fails to come up within the trunk, the immediate first step is checking the physical layer and link-layer protocol status using display interface brief to rule out hardware, cable, or transceiver errors.
VLAN Reachability Issues: If the Eth-Trunk trunk link is successfully built but specific traffic (like PC1 in VLAN 10 to PC3 in VLAN 10) fails to traverse across, it points directly to misconfigured VLAN permissions (e.g., forgetting to allow VLAN 10 on the Eth-Trunk trunk port configuration).
Trunk Establishment Failure: If the logical Eth-Trunk interface itself cannot form, it is typically due to a mismatch in foundational parameters-most notably, one side being configured in standard manual load-balancing mode while the other is using dynamic LACP mode.
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.
Inform Request requires an acknowledgment from the NMS, whereas Trap does not.

During WLAN deployment, a Fit AP fails to go online on the WAC. You log in to the WAC and run the display ap all command to check the AP status. The command output shows that the AP status is unauth, indicating that the AP fails the authentication. You therefore need to confirm this AP on the WAC to allow the AP to go online.

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.

On the OSPF network shown in the figure, S1 is a Layer 2 switch. A total of_____DRs will be elected on this network. (Enter only digits.)
On the OSPF network shown in the figure, S1 is a Layer 2 switch. A total of_____DRs will be elected on this network. (Enter only digits.)
Correct Answer:
1
Explanation:
A DR election occurs on each OSPF broadcast multi-access segment. In this topology, R1, R2, and R3 are connected through the Layer 2 switch S1, forming a single broadcast domain, so only one DR is elected there. The link between R3 and R4 is a point-to-point connection, which does not require DR election. Therefore, only one DR exists in the entire network.
