Nokia 4A0-100 practice questions, page 9 of 13, with answer review and explanations.

Question 41

(Click the Exhibit Button below) An Ethernet Local Area Network (LAN) consists of the following components: - Four 24-port hubs & Two 16-port switches How many broadcast domains are on this LAN?

  1. 1
  2. 2
  3. 5
  4. 32

Question 42

Which of the following best describes an Ethernet bridge?

  1. A passive device simply used to connect two or more cables. Does not generate or amplify any signals.
  2. A device that receives and retransmits a signal out its other ports, but does not do any Layer 2 analysis of the data.
  3. A device that receives a signal and based on the Layer 2 destination address, makes a decision on which ports the signal should be retransmitted.
  4. A device that receives a signal and based on the Layer 3 destination address, makes a decision on which ports the signal should be retransmitted.

Question 43

What happens immediately after an Ethernet switch receives an Ethernet frame?

  1. It records the destination MAC address and the interface on which it arrived.
  2. It records the source MAC address and the interface on which it arrived.
  3. It floods the frame out of all its interfaces except the interface on which the frame arrived.
  4. It transmits the frame out of the appropriate interface.

Question 44

What is the behavior of a typical Ethernet switch when it receives a frame with a uncast destination MAC address? (Choose two)

  1. The switch floods the frame out of all ports except the port on which it was received.
  2. The switch looks in its FDB. If the source address is unknown it discards the frame.
  3. The switch looks in its FDB. If the destination address is known it forwards the frame out the appropriate interface.
  4. The switch looks in its FDB. If the destination address is unknown it floods the frame out all ports except the port on which it was received.
  5. The switch looks in its FDB. If the destination address is unknown it discards the frame.

Question 45

Which technologies can be used with Ethernet switches to achieve redundancy? (Choose two)

  1. LAG
  2. OSPF
  3. RIP
  4. STP
