1. What is a characteristic of the distribution layer in the three layer hierarchical model?
- acts as the backbone for the network, aggregating and distributing network traffic throughout the campus
- provides access to the rest of the network through switching, routing, and network access policies
- distributes access to end users
- represents the network edge
2. What is a definition of a two-tier LAN network design?
- access and core layers collapsed into one tier, and the distribution layer on a separate tier
- access and distribution layers collapsed into one tier, and the core layer on a separate tier
- distribution and core layers collapsed into one tier, and the access layer on a separate tier
- access, distribution, and core layers collapsed into one tier, with a separate backbone layer
3. A network technician is evaluating the desirable features of both access and distribution layer switches. Which two features are common to switches at these two layers? (Choose two.)
- connectivity to the data center
- link aggregation
- application based filtering
4. What are two benefits of extending access layer connectivity to users through a wireless medium? (Choose two.)
- increased flexibility
- decreased number of critical points of failure
- reduced costs
- increased bandwidth availability
- increased network management options
5. Which task would typically require only services that are located at the access layer of the hierarchical design model?
- connecting to the corporate web server to update sales figures
- using a VPN from home to send data to the main office server farm
- responding to an email from a co-worker in another department
- printing a meeting agenda on a departmental network printer in a different VLAN
- intra-VLAN communications between two hosts that reside on the same local departmental network
6. What feature is more important at the core layer than at any other hierarchical network design layer?
- easy access of end devices
- aggregation of network links
- QoS classification and marking
- data security
- packet switching speed
7. Which Cisco Enterprise Architecture module consists of a building or group of buildings consisting of many LANs in a fixed geographic area?
- enterprise branch
- enterprise edge
- enterprise campus
- enterprise data center
8. A network administrator is planning the upgrade of an enterprise LAN to feature Layer 3 support for the application of data security policies, aggregated links, and redundant devices and links. Which switches in the hierarchical three-layer design model support these network requirements?
- core switches
- access switches
- backbone switches
- distribution switches
9. Which two devices would commonly be found at the access layer of the hierarchical enterprise LAN design model? (Choose two.)
- access point
- Layer 2 switch
- Layer 3 device
- modular switch
10. What do companies gain from the services performed at the network edge?
- faster communication with server farms
- stronger security against malicious attacks
- faster communication with Internet destinations
- enhanced performance and reliability through VLANs and redundant trunk links
11. On a campus network, personnel who are located in a five site college have access to servers found in one location. In which network block of the campus network architecture would these servers be found?
- WAN edge
- data center
- Internet edge
- network services
12. A network engineer has to decide between a Layer 2 Access Layer (STP-based) and a Layer 3 Access Layer (Routed access) campus design option. Which statement must be considered for a decision to be made?
- The STP based access option supports spanning VLANs across multiple access switches, whereas the Routed access option does not.
- The Routed access option is the best cost-effective solution.
- The STP based option does not require FHRP, whereas the Routed access option does.
- The Routed access option offers easier troubleshooting than the STP-based option.
