CCNA第三学期英文答案chapter3

1. Which two statements describe the benefits of VLANs? (Choose two.) VLANs improve network performance by regulating flow control and window size. VLANs enable switches to route packets to remote networks via VLAN ID filtering. VLANs reduce network cost by reducing the number of physical ports required on switches. VLANs improve network security by isolating users that have access to sensitive data and applications. VLANs divide a network into smaller logical networks, resulting in lower susceptibility to broadcast storms 2. What are two characteristics of VLAN1 in a default switch configuration? (Choose two.) VLAN1 should renamed. VLAN 1 is the management VLAN. All switch ports are members of VLAN1. Only switch port 0/1 is assigned to VLAN1. Links between switches must be members of VLAN1 3. Refer to the exhibit. SW1 and SW2 are new switches being installed in the topology shown in the exhibit. Interface Fa0/1 on switch SW1 has been configured with trunk mode “on”. Which statement is true about forming a trunk link between the switches SW1 and SW2? Interface Fa0/2 on switch SW2 will negotiate to become a trunk link if it supports DTP. Interface Fa0/2 on switch SW2 can only become a trunk link if statically configured as a trunk. Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link if the neighboring interface is configured in nonegotiate mode. Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link automatically with no consideration of the configuration on the neighboring interface 4. Refer to the exhibit. Computer 1 sends a frame to computer 4. On which links along the path between computer 1 and computer 4 will a VLAN...
