QUESTION 89
What action does a switch take if the destination MAC address is unknown?

A. Discard frame
B. Send ICMP unreachable message to source
C. Flood packet on all ports
D. Compare destination IP address against an ACL to determine if it is permitted
E. Send gratuitous ARP on all ports and wait for reply before forwarding

Answer: C
Explanation:
“What happens though when the switch receives a frame with a destination MAC address that is not included in the table? In that case the switch will just broadcast/flood the frame with the unknown destination address to all of its ports (apart from the port where the frame came from). This process is called unknown unicast flooding. ” http://telconotes.wordpress.com/2013/03/09/how-a-switch-works/

QUESTION 92
Which two networking devices operate at Layer 1 of the OSI model? (Choose two.)

A. Repeater
B. Bridge
C. Switch
D. Router
E. Hub

Answer: AE
Explanation:
It defines the electrical and physical specifications of the data connection. It defines the relationship between a device and a physical transmission medium (e.g. a copper or fiber optical cable). This includes the layout of pins, voltages, line impedance, cable specifications, signal timing, hubs, repeaters, network adapters, host bus adapters (HBA used in storage area networks) and more.”

QUESTION 96
What are two features of a bridge? (Choose two.)

A. Reliable transmission
B. Operate at OSI Layer 2
C. Operate at OSI Layer 3
D. Create multiple broadcast domains
E. Create multiple collision domains
F. Flood input packets to all ports
G. Drop IP packets with invalid destination ports

Answer: BE
Explanation:
“- a bridge is a two interfaces device that creates 2 collision domains, since it forwards the traffic it receives from one interface only to the interface where the destination layer 2 device (based on his mac address) is connected to. A bridge is considered as an “intelligent hub” since it reads the destination mac address in order to forward the traffic only to the interface where it is connected”
