Question 46

In what type of network is a broadcast storm likely to occur?

  1. An Ethernet network with redundant paths not running STP.
  2. An ATM network.
  3. A SONET network.
  4. All of the above.

Question 47

What problems was Spanning Tree Protocol (STP) primarily designed to solve? (Choose two):

  1. Providing path redundancy.
  2. Preventing loops.
  3. Handling collisions.
  4. Allowing flooding of multicast traffic.

Question 48

Which of the following is a feature of a VLAN?

  1. A VLAN allows multiple Ethernet switches to be connected in a single broadcast domain.
  2. A VLAN allows multiple Ethernet switches to be connected in a single collision domain.
  3. A VLAN can separate ports on the same switch into different broadcast domains.
  4. A VLAN can separate ports on the same switch into different collision domains.

Question 49

What is required if devices on different VLANs wish to communicate with each other?

  1. Devices on different VLANs cannot communicate with each other.
  2. Devices on different VLANs can communicate with each other as long as they are connected to the same switch.
  3. Devices on different VLANs can communicate with each other as long as the switches they are attached to are connected to each other with an Ethernet connection.
  4. Devices on different VLANs can communicate with each other if there is an IP router to connect the VLANs.

Question 50

A 24 port Ethernet switch is configured with VLAN 100 on ports 1 - 8, VLAN 200 on ports 9 - 16 and VLAN 300 on ports 17 - 24. Which of the following describes the behavior of the switch when a broadcast frame is received on port 1?

  1. The switch will discard the broadcast frame because there is no specific destination address.
  2. The switch will flood the broadcast frame on all ports on which the switch has seen frames from attached devices
  3. The switch will flood the broadcast frame on ports 2 to 8.
  4. The switch will flood the broadcast frame on all 24 ports.
