In which area of the campus LAN are the user computers attached to the network?

  1. core
  2. access
  3. distribution
  4. aggregation

Answer(s): B

Explanation:

Cisco has defined a hierarchical model known as the hierarchical internetworking model. This model simplifies the task of building a reliable, scalable, and less expensive hierarchical internetwork because rather than focusing on packet construction, it focuses on the three functional areas, or layers, of your network:
Core layer: This layer is considered the backbone of the network and includes the high-end switches and high-speed cables such as fiber cables. This layer of the network does not route traffic at the LAN. In addition, no packet manipulation is done by devices in this layer. Rather, this layer is concerned with speed and ensures reliable delivery of packets.
Distribution layer: This layer includes LAN-based routers and layer 3 switches. This layer ensures that packets are properly routed between subnets and VLANs in your enterprise. This layer is also called the Workgroup layer.
Access layer: This layer includes hubs and switches. This layer is also called the desktop layer because it focuses on connecting client nodes, such as workstations to the network. This layer ensures that packets are delivered to end user computers.

  4. Increase in mobile workers is requiring companies to overcome the location border so that information can be accessed from anywhere.
  5. Enterprises are increasingly hesitant to become borderless due to varying user experiences, security, and reliability issues.

Answer(s): B,D



What is the goal of the Cisco Borderless Network Architecture?

  1. to provide users with a single device that permits access to information anywhere
  2. to provide users with the same productivity and access to information no matter where they are or which device they use
  3. to eliminate the need for border security and firewalls
  4. to provide companies with a way to extend their security and control over employees on the Internet
