Q62. Which three are considered as technical constraints when identifying network requirements? (Choose three.) 

A. support for legacy applications 

B. bandwidth support for new applications 

C. limited budget allocation 

D. policy limitations 

E. limited support staff to complete assessment 

F. support for existing legacy equipment 

G. limited timeframe to implement 

Answer: A,B,F 


Network design might be constrained by parameters that limit the solution. Legacy applications might still exist that must be supported going forward, and these applications might require a legacy protocol that may limit a design. Technical constraints include the following: 

.Existing wiring does not support new technology. 

.Bandwidth might not support new applications. 

.The network must support exiting legacy equipment. 

.Legacy applications must be supported (application compatibility). 

Q63. Which of the following three options represents the components of the Teleworker Solution? (Choose three.) 

A. Cisco Unified IP Phone 

B. Cisco 880 Series Router 

C. Aironet Office Extend Access Point 

D. Catalyst 3560 Series Switch 

E. Cisco 2900 Series Router 

F. MPLS Layer 3 VPN 

G. Leased lines 

Answer: A,B,E 


A Cisco ASR is used to terminate Teleworker solutions, not a 2900 series router. Hybrid teleworker uses Aironet, Advanced teleworker uses 880, both use IP phones. google: "at_a_glance_c45-652500.pdf" for details 

The Cisco Virtual Office Solution for the Enterprise Teleworker is implemented using the Cisco 800 series ISRs. Each ISR has integrated switch ports that then connect to the user’s broadband connection. The solution uses a permanent always-on IPsec VPN tunnel back to the corporate network. This architecture provides for centralized IT security management, corporate-pushed security policies, and integrated identity services. In addition, this solution supports the enterprise teleworker needs through advanced applications such as voice and video. For example, the enterprise teleworker can take advantage of toll bypass, voicemail, and advanced IP phone features not available in the PSTN. 

Enterprise Teleworker Module 

The enterprise teleworker module consists of a small office or a mobile user who needs to access services of the enterprise campus. As shown in Figure 2-14, mobile users connect from their homes, hotels, or other locations using dialup or Internet access lines. VPN clients are used to allow mobile users to securely access enterprise applications. The Cisco Virtual Office solution provides a solution for teleworkers that is centrally managed using small integrated service routers (ISR) in the VPN solution. IP phone capabilities are also provided in the Cisco Virtual Office solution, providing corporate voice services for mobile users. 



Q65. Which two mechanisms are used by distance vector protocols to prevent routing loops? (Choose two.) 

A. split horizon 

B. route summarization 

C. route poisoning 

D. tuned timers 

Answer: A,C 

Q66. What device virtualization technology allows for a single point of management and a centralized routing instance? 




D. VM 


Q67. Which statement describes an advantage of the Layer 2 access model over the Layer 3 access model in the data center? 

A. It enables NIC teaming. 

B. It removes STP dependency. 

C. It increases scalability. 

D. It decreases convergence. 


Q68. Which three statements are true regarding the virtual interface on a Cisco Wireless LAN Controller? (Choose three.) 

A. supports mobility management 

B. serves as a DHCP relay 

C. used for all controller to AP communication 

D. supports embedded Layer 3 security 

E. default for out-of-band management 

F. default for in-band management 

G. provides connectivity to AAA servers 

Answer: A,B,D 

Q69. What Cisco product is designed to improve the performance of Windows file and exchange services in remote data centers? 

A. Application Control Engine 

B. Wide Area Application Services 

C. Cisco Application Policy Infrastructure Controller 

D. Cisco Prime Network Services Controller 


Q70. An application uses broadcast traffic to send data to IPv4 hosts. How can the application communicate using IPv6? 

A. Anycast 

B. Unicast 

C. Broadcast 

D. Multicast
