CCNA 3 Chapter 1 V4
1. Which layer of the hierarchical network design model is refered to as the high-speed backbone of the internetwork, where high availability and redundancy are critical?
core layer
2. Which two characteristics are associated with enterprise level switches? (Choose two.) high forwarding rate support link aggregation
3. Which feature supports higher throughput in switched networks by combining multiple switch ports? link aggregation
4. Which hierarchical design model layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs (VLANs)? distribution 5. What is the likely impact of moving a conventional company architecture to a completely converged network?
A shared infrastructure is created resulting in a single network to manage.
6. Refer to the exhibit. Beginning with HR servers and workstations, a network engineer is designing a new security structure for the network. Which set of policies adheres to the hierarchical network model design principles?
Configure port security options on S1. Use Layer 3 access control features on D1 and D2 to limit access to the HR servers to just the HR subnet.
7. Which three features are commonly supported at the distribution layer of the Cisco hierarchical network model? (Choose three.) security policies quality of service
Layer 3 functionality
8. Configuring communication between devices on different VLANs requires the use of which layer of the OSI model?
Layer 3
9. Which layer of the OSI model does an access layer LAN switch use to make a forwarding decision?
Layer 2
10. Which two features are supported at all three levels of the Cisco three-layer hierarchical model? (Choose two.)
Quality of Service link aggregation
11. A network technician is asked to examine an existing switched network. Following this examination, the technician makes recommendations for adding new
