Q3. Refer to the exhibit. 

Which of the following two are advantages of Server virtualization using VMware vSphere? (Choose two) 

A. Retains the one-to-one relationship between switch ports and functional servers B. Enables the live migration of a virtual server from one physical server to another without disruption to users or loss of services 

C. The access layer of the network moves into the vSphere ESX servers, providing streamlined vSphere management 

D. Provides management functions including the ability to run scripts and to install third-party agents for hardware monitoring, backup, or systems management 

E. New functional servers can be deployed with minimal physical changes on the network 

Answer: B,D 

Q4. Which two options are advantages of having a modular design instead of an EOR design in a data center? (Choose two.) 

A. cooling constraints 

B. cable bulk 

C. decreased STP processing 

D. redundancy options 

E. cost minimization 

F. low-skilled manager 

Answer: C,D 

Q5. Which two design recommendations are most appropriate when EIGRP is the data center core routing protocol? (Choose two.) 

A. Summarize data center subnets. 

B. Advertise a default route into the data center core from the aggregation layer. 

C. Tune the EIGRP timers to enable EIGRP to achieve quicker convergence. 

D. Adjust the default bandwidth value to ensure proper bandwidth on all links. 

Answer: A,B 

Q6. Which option describes why duplicate IP addresses reside on the same network in Cisco network design? 

A. HSRP designed network 

B. using Cisco ACE in active/passive mode 

C. VRRP designed network 

D. running multiple routing protocols 

Answer:

Q7. A network engineer is building a LAN design that includes Cisco NAC. What two characteristics of an out-of-band NAC deployment are important to consider when evaluating it for the design? (Choose two.) 

A. supported by a limited number of switch models 

B. never in-line with user traffic 

C. aggregate client traffic is constrained to NAC server port speed 

D. recommended if sharing ports between IP phones and PCs 

E. supports real IP gateway (routed mode) 

Answer: A,D 

Q8. A network team must provide a redundant secure connection between two entities using OSPF.

B. HTTPS 

C. Root Certificate 

D. AAA Server 

Answer:

Q9. When designing remote access to the Enterprise Campus network for teleworkers and mobile workers, which of the following should the designer consider? 

A. It is recommended to place the VPN termination device in line with the Enterprise Edge firewall, with ingress traffic limited to SSL only 

B. Maintaining access rules, based on the source IP of the client, on an internal firewall drawn from a headend RADIUS server is the most secure deployment 

C. VPN Headend routing using Reverse Route Injection (RRI) with distribution is recommended when the remote user community is small and dedicated DHCP scopes are in place 

D. Clientless SSL VPNs provide more granular access control than SSL VPN clients (thin or thick), including at Layer7
