Which statement is true about broadcast and collision domains?

• Adding a switch to a network will increase the size of the broadcast domain
• Adding a router to a network will increase the size of the collision domain
• The more interfaces a router has the larger the resulting broadcast domain
• The size of the collision domain can be reduced by adding hubs to a network
• Adding a switch to a network will decrase the size of the broadcast domain

What is one function of a Layer 2 switch?

• Duplicates the electrical signal of each frame to every portt
• Learns the port assigned to a hostt by examining the destination MAC address
• Determines which interface is used to forward a frame on the destination MAC address
• Forwards data based on lofical addressing
• To manage the layer 3 packets

Which switch characteristic helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port?

• High port density
• Frame buffering
• Fast internal switching
• Fast port speed
• ASIC

Which switching method makes use of the FCS value?

• Fragment-free
• A large frame buffer
• Fast-forward
• Cut-through
• Store-and-forward

Which two statements are true about half-duplex and full-duplex communications? (Choose two.)

• Full duplex offers 100% potential use of the bandwidth
• Half duplex has only one channel
• Full duplex allows both ends to transmit and receive simultaneously
• Full duplex increases the effective bandwidth
• All modern NICs support both half and full duplex communication

Which network device can be used to eliminate collisions on an Ethernet network?

• Switch
• Hub
• Firewall
• Router
• Host

Which network device can serve as a boundary to divide a Layer 2 broadcast domain?

• Access point
• Ethernet bridge
• Ethernet hub
• Router
• Switch

Which type of address does a switch use to build the MAC address table?

• Layer 4 protocol
• Destination IP address

What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table?

• Drop the frame
• Forward the frame out all ports except the port where the frame is received
• Send the frame to the default gateway address
• Use ARP to resolve the port that is related to the frame
• Adds the destination MAC address to the MAC table
