Question 46

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.

Question 47

The method by which Ethernet frames are associated to a specific VLAN is referred to as:

  1. Segmenting
  2. Stacking
  3. Routing
  4. Tagging

Question 48

What information is used to separate VLANs on a VLAN trunk that connects multiple VLANs?

  1. VLAN tag.
  2. IP Header.
  3. FCS.
  4. Priority Value.

Question 49

Using Q-in-Q Virtual Local Area Network (VLAN) stacking, how does a carrier differentiate one customers traffic from that of another?

  1. The provider edge (PE) switch adds an additional field called a PE tag to the customers Layer 2 data.
  2. The PE switch replaces the customers VLAN tag with a carrier-assigned tag.
  3. The PE switch adds a second VLAN tag to identify the customers traffic on the carriers network.
  4. The PE switch assigns a customer-specific priority label to the customers traffic.

Question 50

What is the purpose of the Data Link Layer in the OSI model?

  1. The Data Link Layer is responsible for encapsulating the packet into a frame for transmission on the transmission media.
  2. The Data Link Layer is responsible for encapsulating the packet into an IP header and routing the packet.
  3. The Data Link Layer is responsible for formatting the packet for applications such as JPEG format.
  4. The Data Link Layer is responsible for timing of the signals on the transmission media
