Which layer of the hierarchical network design model is refered to as the high-speed backbone of the internetwork, where high availability and redundancy arecritical?access layercore layerdata-link layerdistribution layernetwork layerphysical layer2. Which two characteristics are associated with enterprise level switches? (Choosetwo.)low port densityhigh forwarding ratehigh latency levelsupport link aggregationpredefined number of ports3. Which feature supports higher throughput in switched networks by combiningmultiple switch ports?convergenceredundant linkslink aggregationnetwork diameter4. Which hierarchical design model layer controls the flow of network traffic usingpolicies and delineates broadcast domains by performing routing functions betweenvirtual LANs (VLANs)?applicationaccessdistributionnetworkcore5. What is the likely impact of moving a conventional company architecture to acompletely converged network?Local analog phone service can be completely outsourced to cost-effective providers.The Ethernet VLAN structure is less complex.A shared infrastructure is created resulting in a single network to manage.QoS issues are greatly reduced.There is less bandwidth competition between voice and video streams.6.

Beginning with HR servers and workstations, a networkengineer is designing a new security structure for the network. Which set of policiesadheres to the hierarchical network model design principles?Implement Layer 3 switching on S1 to reduce the packet processing load on D1 and D2.Install all security processing on S1 to reduce network traffic load.Configure port security options on S1. Use Layer 3 access control features on D1 and D2to limit access to the HR servers to just the HR subnet.Move all HR assets out of the data center and connect them to S1. Use Layer 3 securityfunctions on S1 to deny all traffic into and out of S1.Perform all port access and Layer 3 security functions on C1.7.
