Q51. Which protocol is used in an in-band network and why? 

A. UDP, because it is connectionless 

B. SSH, because the username and password are encrypted 

C. Telnet, because the username and password are sent in clear 

D. MSDP, because it uses TCP as its transport protocol 

Answer:


Q52. Which option is an.advantage of using PIM sparse mode instead of PIM dense mode? 

A. No RP is required. 

B. There is reduced congestion in the network. 

C. IGMP is not required. 

D. It floods all multicast traffic throughout the network. 

Answer:


Q53. Which routing protocol provides the fastest convergence and greatest flexibility within a campus environment? 

A. OSPF 

B. IS-IS 

C. BGP 

D. EIGRP 

Answer:


Q54. Which two VPN solutions extend the routing capabilities of basic IPsec VPNs? (Choose two.) 

A. GRE 

B. NVI 

C. DES 

D. VTI 

E. AES 

Answer: A,D 


Q55. 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:


Q56. Which of the following is most accurate with respect to designing high availability within the Enterprise Campus network? 

A. High availability at and between the Distribution and Access layers is as simple as redundant switches and redundant Layer 3 connections 

B. Non-deterministic traffic patterns require a highly available modular topology design 

C. Distribution layer high availability design includes redundant switches and Layer 3 equal-cost load sharing connections to the switched Access and routed Core layers, with a Layer 3 link between the Distribution switches to support summarization of routing information from the Distribution to the Core 

D. Default gateway redundancy allows for the failure of a redundant Distribution switch without affecting endpoint connectivity 

Answer:


Q57. Which statement about Fibre Channel communications is correct? 

A. N_Port to N_Port connections use logical node connection points. 

B. Flow control is only provided by QoS. 

C. It must be implemented in an arbitrated loop. 

D. Communication methods are similar to those of an Ethernet bus. 

Answer:


Q58. 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 


Q59. A designer should have which three technologies in the network before configuring MPLS Layer 3 VPNs? (Choose three.) 

A. MPLS 

B. LDP 

C. Cisco Express Forwarding 

D. VSS 

E. vPC 

F. VRRP 

Answer: A,B,C 


Q60. Why is QoS important for in-band management? 

A. It supports remote management when traffic volume is high. 

B. It supports proper routing. 

C. It supports network security against DoS attacks and worm outbreaks. 

D. It supports network redundancy.
