Check Your Understanding Questions

Complete all the review questions listed here to test your understanding of the topics and concepts in this chapter. The appendix, “Answers to the ‘Check Your Understanding’ Questions,” lists the answers.

  1. Which three options correctly associate a layer of the hierarchical design model with the function of that layer? (Choose three.)

    1. Core - end device connectivity
    2. Distribution - aggregation and traffic control
    3. Access - end device connectivity
    4. Distribution - high speed backbone
    5. Access - aggregation of traffic
    6. Core - high speed backbone
  2. Which hierarchical network design goal is to provide a way for the network to always be accessible?

    1. hierarchical
    2. modularity
    3. resiliency
    4. flexibility
  3. Which two layers of the hierarchical network design model are commonly combined into a single layer in a small-to-medium sized network architecture? (Choose two.)

    1. access
    2. data link
    3. network
    4. distribution
    5. application
    6. core
  4. What is convergence as it relates to network design?

    1. Implementation of an access-distribution-core layer design model for all sites in a corporation
    2. A centralized point in the network design where all traffic aggregates before transmission to the destination
    3. The combining of voice and video with traditional network traffic
    4. Designing a network in such a way that each tier has a specific function and upgrade path
  5. What are three benefits of a converged network? (Choose three.)

    1. Voice and data support staff are combined.
    2. Network design is simplified.
    3. Network configuration is simplified.
    4. Voice, video, and data traffic use one physical network.
    5. Maintenance is simpler than hierarchical networks.
    6. Network moves, adds, and changes are simplified.
  6. Which two terms are correctly defined? (Choose two.)

    1. Internal switching rate - processing capability of a switch that quantifies how much data it can process per second
    2. Port density - capability to use multiple switch ports concurrently for higher throughput data communication
    3. Rack unit - number of ports that can fit in a specific switch
    4. Cut-through switching - the transmission of a frame after the destination MAC address has been examined and processed
    5. Modular configuration switch - only support features or options that ship with the device
  7. A switch that uses MAC addresses to forward frames operates at which layer of the OSI model?

    1. Layer 1
    2. Layer 2
    3. Layer 3
    4. Layer 4
  8. A switch has just been powered on. PC1 connects to port 1; PC2 connects to port 2. If PC1 sends data to PC2, how will the switch process the frame?

    1. The switch forwards the frame based on the MAC address of PC2.
    2. The switch adds the MAC address of PC1 (that is received on the ingress port) to the switch MAC address table.
    3. The switch forwards the frame to all switch ports including ports 1 and 2.
    4. The switch adds the IP address of PC2 (that is sent through the egress port) to the switch MAC address table.
  9. What function is most likely to be provided by a Cisco access layer switch?

    1. PoE
    2. Routing
    3. Link aggregation
    4. Fault isolation
  10. Use the abbreviated MAC addresses in the MAC address table to determine the correct answer. A PC connected to port Gi0/3 sends data to a PC connected to port Gi0/5. When the switch receives the data, what will the switch do to process the frame?

    Port MAC address

    Gi0/3 AA

    Gi0/7 AB

    1. Add the destination MAC address to the switch MAC address table.
    2. Forward the data out all ports except for port Gi0/3.
    3. Forward the data to port Gi0/3.
    4. Forward the data out all ports.
    5. Add both the source and destination MAC addresses to the switch MAC address table.
  11. Use the abbreviated MAC addresses in the MAC address table to determine the correct answer. A PC connected to port Gi0/4 sends data to a PC connected to port Gi0/3. When the switch receives the data, what will the switch do first to process the frame?

    Port MAC address

    Gi0/3 AA

    Gi0/7 AB

    1. Add the source MAC address to the switch MAC address table.
    2. Forward the data out all ports except for port 4.
    3. Forward the data to port 5.
    4. Forward the data out all ports.
    5. Add both the source and destination MAC addresses to the switch MAC address table.
    6. Add the destination MAC address to the switch MAC address table.
