Question 1

Question
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?
Answer
  • It compares the unicast destination address to the bridging, or MAC address, table.
  • It compares the unicast source address to the bridging, or MAC address, table.
  • It forwards the frame out all interfaces in the same VLAN except for the incoming interface.
  • It compares the destination IP address to the destination MAC address.
  • It compares the frame’s incoming interface to the source MAC entry in the MAC address table.

Question 2

Question
Which of the following statements describes part of the process of how a LAN switch decides to forward a frame destined for a broadcast MAC address?
Answer
  • It compares the unicast destination address to the bridging, or MAC address, table.
  • It compares the unicast source address to the bridging, or MAC address, table.
  • It forwards the frame out all interfaces in the same VLAN except for the incoming interface.
  • It compares the destination IP address to the destination MAC address.
  • It compares the frame’s incoming interface to the source MAC entry in the MAC address table.

Question 3

Question
Which of the following statements best describes what a switch does with a frame destined for an unknown unicast address?
Answer
  • It forwards out all interfaces in the same VLAN except for the incoming interface.
  • It forwards the frame out the one interface identified by the matching entry in the MAC address table.
  • It compares the destination IP address to the destination MAC address.
  • It compares the frame’s incoming interface to the source MAC entry in the MAC address table.

Question 4

Question
Which of the following comparisons does a switch make when deciding whether a new MAC address should be added to its MAC address table?
Answer
  • It compares the unicast destination address to the bridging, or MAC address, table.
  • It compares the unicast source address to the bridging, or MAC address, table.
  • It compares the VLAN ID to the bridging, or MAC address, table.
  • It compares the destination IP address’s ARP cache entry to the bridging, or MAC address, table.

Question 5

Question
PC1, with MAC address 1111.1111.1111, is connected to Switch SW1’s Fa0/1 interface. PC2, with MAC address 2222.2222.2222, is connected to SW1’s Fa0/2 interface. PC3, with MAC address 3333.3333.3333, connects to SW1’s Fa0/3 interface. The switch begins with no dynamically learned MAC addresses, followed by PC1 sending a frame with a destination address of 2222.2222.2222. If the next frame to reach the switch is a frame sent by PC3, destined for PC2’s MAC address of 2222.2222.2222, which of the following are true? (Choose two answers.)
Answer
  • The switch forwards the frame out interface Fa0/1.
  • The switch forwards the frame out interface Fa0/2.
  • The switch forwards the frame out interface Fa0/3.
  • The switch discards (filters) the frame.

Question 6

Question
Which of the following devices would be in the same collision domain as PC1?
Answer
  • PC2, which is separated from PC1 by an Ethernet hub
  • PC3, which is separated from PC1 by a transparent bridge
  • PC4, which is separated from PC1 by an Ethernet switch
  • PC5, which is separated from PC1 by a router

Question 7

Question
Which of the following devices would be in the same broadcast domain as PC1? (Choose three answers.)
Answer
  • PC2, which is separated from PC1 by an Ethernet hub
  • PC3, which is separated from PC1 by a transparent bridge
  • PC4, which is separated from PC1 by an Ethernet switch
  • PC5, which is separated from PC1 by a router

Question 8

Question
Which of the following Ethernet standards support a maximum cable length of longer than 100 meters? (Choose two answers.)
Answer
  • 100BASE-T
  • 1000BASE-LX
  • 1000BASE-T
  • 100BASE-FX

Question 9

Question
A Cisco LAN switch connects to three PCs (PC1, PC2, and PC3), each directly using a cable that supports Ethernet UTP speeds up through 1000 Mbps (1 Gbps). PC1 uses a NIC that supports only 10BASE-T, while PC2 has a 10/100 NIC, and PC3 has a 10/100/1000 NIC. Assuming that the PCs and switch use IEEE autonegotiation, which PCs will use half-duplex?
Answer
  • PC1
  • PC2
  • PC3
  • None of the PCs will use half-duplex.
