Q124. Refer to the exhibit. 

Which statement accurately represents the characteristics of the core layer in this design? 

A. QoS should only be performed only in the core. 

B. Load balancing should never be implemented or used. 

C. Access lists should be used in the core to perform packet manipulation. 

D. Partial mesh should be used as long as it is connected to each device by multiple paths.

A. access lists 

B. IP security 

C. context based access 

D. intrusion prevention system

Q127. What are the three primary functions of the distribution layer of the campus network design hierarchy? (Choose three.) 

A. provide end-user connectivity 

B. provide high speed transport 

C. provide QoS services 

D. enforce security policies

Q128. Which statement describes the recommended deployment of DNS and DHCP servers in the Cisco Network Architecture for the Enterprise? 

A. Place the DHCP and DNS servers in the Enterprise Campus Access layer and Enterprise branch. 

B. Place the DHCP and DNS servers in the Enterprise Campus Server Farm layer and Enterprise branch. 

C. Place the DHCP server in the Enterprise Campus Core layer and Remote Access_VPN module with the DNS server in the Internet Connectivity module. 

D. Place the DHCP server in the Enterprise Campus Distribution layer with the DNS server in the Internet Connectivity module. 

Answer:

Explanation: For the Enterprise Campus, DHCP and internal DNS servers should be located in the Server Farm and they should be redundant. External DNS servers can be placed redundantly at the service provider facility and at the Enterprise branch.
