ICND -1 LAN Switching Fundamentals

Which two of these statements regarding 801.1Q trunking are correct? (Choose two)

• 801.1Q native VLAN frames are untagged by default

• 801.1Q trunking ports can also be secure ports

• 801.1Q trunks should have native VLANs that are the same at bot hends

• 801.1Q native VLAN frames are always untagged and cannot be tagged

• 801.1Q trunks require full-duplex, point-to-point connectivity

What is the maximum size of an Ethernet frame that uses 801.1Q tagging?

• 68 bytes

• 128 bytes

• 1522 bytes

• 1514 bytes

Which feature builds a FIB and an adjacency table to expedite packet forwarding?

• Cut through

• Process switching

• Cisco Express Forwarding

• Fast switching

When HostA pings HostB, which entry will be in the ARP cache of HostA to support this transmission, after the ping?

• 
• 
• 
• 

What is used to allow multiple VLANs between switches without using a L3 device?

• STP

• DHCP

• Trunk

Why will a switch never learn a broadcast address?

• A broadcast address will never be the source address of a frame

• A broadcast frame is never forwarded by a switch

• Broadcast frames are never sent to switches

• Broadcast addresses use an incorrect format for the switching table

• Broadcasts only use network layer addressing

Which two attributes change all along the pathway from source to destination in network communication? (Choose two)

• IP destination address

• MAC source address

• IP source address

• MAC destination address

On a Cisco switch, which protocol determines if an attached VoIP phone is from Cisco or from another vendor

• TCP

• UDP

• RTP

• CDP

For what two purposes does the Ethernet protocol use physical addresses? (Choose two)

• To differentiate a Layer 2 frame from a Layer 3 packet

• To allow communication between different devices on the same network

• To allow communication with devices on a different network

• To allow detection of a remote device when its physical address is unknown

• To uniquely identify devices at Layer 2

After you configure the Loopback0 interface, which command can you enter to verify the status of the interface and determine whether fast switching is enabled

• Show run

• Show interface Loopback 0

• show ip interface loopback 0

• show ip interface brief
