Q141. Which of the following facts must be considered when designing for IP telephony within an Enterprise Campus network?
A. Because the IP phone is a three-port switch, IP telephony extends the network edge, impacting the Distribution layer.
B. Video and voice are alike in being bursty and bandwidth intensive, and thus impose requirements to be lossless, and have minimized delay and jitter.
C. IP phones have no voice and data VLAN separation, so security policies must be based on upper layer traffic characteristics.
D. Though multi-VLAN access ports are set to dot1q and carry more than two VLANs they are not trunk ports.
Answer: D
Q142. A campus network utilizes EIGRP to connect to.several remote branch offices.
Which configuration should be established on all branch routers to improve routing scalability and performance?

C. Adjust EIGRP k-values to utilize delay.
D. Utilize offset lists to direct traffic more efficiently.
Answer: B

Q149. 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
Answer: D
