Question 51

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 52

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 53

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 54

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

Question 55

Which of the following is typically a characteristic of Layer 2 framing?

  1. Provides a universal addressing scheme to uniquely identify destinations in the network.
  2. The size of the Layer 2 frame cannot exceed 1518 bytes.
  3. Provides error checking of the frame contents after transmission.
  4. All the above.
