. Which of the following statements describes part of the process of how a switch decides to forward a frame destined for a known unicast MAC address?
a.) It compares the unicast destination address to the bridging, or MAC address, table.
b.) It compares the unicast source address to the bridging, or MAC address, table.
c.) It forwards the frame out all interfaces in the same VLAN except for the incoming interface.
d.) It compares the destination IP address to the destination MAC address.
e.) It compares the frame’s incoming interface to the source MAC entry in the MAC address table.
a.) It compares the unicast destination address to the bridging, or MAC address, table.
Which of the following statements best describes the forwarding logic that a LAN switch, with all interfaces assigned to VLAN 1 as per default settings, uses for an incoming frame with a destination MAC address of FFFF.FFFF.FFFF?
a.)It forwards the frame out all switch ports.
b.)It forwards the frame out all switch ports except the arrival port.
c.)It forwards the frame out all ports that had earlier registered to ask to receive broadcasts.
d.)It discards the frame.
b.)It forwards the frame out all switch ports except the arrival port.
Which of the following statements best describes what a switch does with a frame destined for an unknown unicast address?
a.)It forwards out all interfaces in the same VLAN except for the incoming interface.
b.)It forwards the frame out the one interface identified by the matching entry in the MAC address table.
c.)It compares the destination IP address to the destination MAC address.
d.)It compares the frame’s incoming interface to the source MAC entry in the MAC address table.
a.)It forwards out all interfaces in the same VLAN except for the incoming interface.
Which of the following comparisons does a switch make when deciding whether a new MAC address should be added to its MAC address table?
a.)It compares the unicast destination address to the bridging, or MAC address, table.
b.)It compares the unicast source address to the bridging, or MAC address, table.
c.)It compares the VLAN ID to the bridging, or MAC address, table.
d.)It compares the destination IP address’s ARP cache entry to the bridging, or MAC address, table.
b.)It compares the unicast source address to the bridging, or MAC address, table.
A Cisco Catalyst switch has 24 10/100 ports, numbered 0/1 through 0/24. Ten PCs connect to the ten lowest numbered ports, with those PCs working and sending data over the network. The other ports are not connected to any device. Which of the following answers lists facts displayed by the show interfaces status command?
a.)Port Ethernet 0/1 is in a connected state.
b.)Port Fast Ethernet 0/11 is in a connected state.
c.)Port Fast Ethernet 0/5 is in a connected state.
d)Port Ethernet 0/15 is in a notconnected state.
c.)Port Fast Ethernet 0/5 is in a connected state.
