How does STP prevent forwarding loops at OSI Layer 2?. MAC address forwarding. Port blocking. TTL. Collision avoidance. Which state does the switch port move to when PortFast is enabled?. forwarding. learning. blocking. listening. What is the primary effect of the spanning-tree portfast command?. It enables BPDU messages. It minimizes spanning-tree convergence time. It immediately puts the port into the forwarding state when the switch is reloaded. It immediately enables the port in the listening state. Refer to the exhibit. Which switch becomes the root bridge?. S2. S4. S3. S1. When using Rapid PVST+, which command guarantees the switch is always the root bridge for VLAN 200?. spanning-tree vlan 200 priority 0. spanning-tree vlan 200 priority 614440. spanning-tree vlan 200 priority 38572422. spanning-tree vlan 200 priority root primary. Refer to exhibit. How does SW2 interact with other switches in this VTP domain? *SW2 vtp domain cisco vtp mode transparent vtp password test interface fastethernet0/1 description connection to SW1 switchport mode trunk switchport trunk encapsulation dot1q. It forwards only the VTP advertisements that it receives on its trunk ports. It processes VTP updates from any VTP clients on the network on its access ports. It transmits and processes VTP updates from any VTP Clients on the network on its trunk ports. It receives updates from all VTP servers and forwards all locally configured VLANs out all trunk ports. Which configuration ensures that the switch is always the root for VLAN 750?. Switch(config)#spanning-tree vlan 750 priority 0. Switch(config)#spanning-tree vlan 750 root primary. Switch(config)#spanning-tree vlan 750 priority 38003685. Switch(config)#spanning-tree vlan 750 priority 614440. Which result occurs when PortFast is enabled on an interface that is connected to another switch?. After spanning tree converges PortFast shuts down any port that receives BPDUs. Spanning tree may fail to detect a switching loop in the network that causes broadcast storms. VTP is allowed to propagate VLAN configuration information from switch to switch automatically. Root port choice and spanning tree recalculation are accelerated when a switch link goes down. Refer to the exhibit. Which switch in this configuration will be elected as the root bridge? ***** SW1: 0C:E0:38:00:36:75 SW2: 0C:0E:15:22:05:97 SW3: 0C:0E:15:1A:3C:9D SW4: 0C:E0:18:A1:B3:19. SW2. SW1. SW3. SW4. Refer to the exhibit. What two conclusions should be made about this configuration? (Choose two). The spanning-tree mode is Rapid PVST+. The designated port is FastEthernet 2/1. The spanning-tree mode is PVST+. The root port is FastEthernet 2/1. This is a root bridge. Refer to the exhibit *** Switch1: 0C.E0.38.57.24.22 Switch2: 0C.0E.15.22.1A.61 Switch3: 0C.0E.15.1D.3C.9A Switch4: 0C.E0.19.A1.4D.16. Switch 1. Switch 4. Switch 3. Switch 2. What criteria is used first during the root port selection process?. lowest neighbor's bridge ID. local port ID. lowest path cost to the root bridge. lowesr neighbor's port ID. Which spanning-tree enhancement avoids the learning and listening states and immediately places ports in the forwarding state?. BPDU filter. PortFast. Backbonefast. BPDUguard. |
