16. See the illustration. Network engineers are preparing to design a new security structure for the network from the HR server and workstation. Which of the following policies comply with the design principles of the hierarchical network model?
	Layer-4 switching is implemented on S1 to reduce the data packet processing workload on D1 and D2. Install all security processing tools on S1 to reduce network traffic load.
	Configure all port security options on S1. Use the 3rd layer access control function on D1 and D2 to restrict access to the HR server to hosts in the HR subnet.
	Remove all HR assets from the data center and connect to S1. On S1, use the 3rd layer security function to deny all traffic from and out of S1.
	Execute all port access and layer 3rd security functions on C1

 

 

 

17. What are the two features of enterprise-level switches? (Select two items .)
	Low port density

18. Which layer of the OSI model is used by the access layer LAN switch to make forwarding decisions?
	Layer 3
	Layer 3
	Layer 3
	Layer 3

 

 

19. What is the potential impact of migrating from a traditional corporate network architecture to a fully integrated network?
	Local simulated telephone services can be completely outsourced to providers with lower fees.
	The Ethernet VLAN structure is simplified.
	A shared infrastructure is formed, so only one network needs to be managed.
	QoS issues will be greatly mitigated.
	Bandwidth competition between voice data streams and video data streams reduces
